VXI is used in many different applications ranging from test and measurement and ATE, to data acquisition and analysis in both research and industrial automation. Although some VXI systems today are purely VXI, many users are migrating to VXI by integrating it into existing systems consisting of GPIB instruments, VME cards, or plug-in data acquisition (DAQ) boards. You can control a VXI system with a remote general-purpose computer using the high-speed Multisystem eXtension Interface (MXI) bus interface or GPIB. You can too embed a computer into a VXI chassis and control the system directly. Whatever your system configuration needs may be, VXI offers the flexibility and performance to pick on today’s most challenging applications.The requisite for VXIbus
The exact for an industry-standard instrument-on-a-card architecture has been driven by the requisite for physical size reduction of rack-and-stack instrumentation systems, tighter timing and synchronization between multiple instruments, and faster transfer rates than the 1 Mb/s rate of the 8-bit GPIB. The modular form factor, elevated bandwidth, and commercial success of the VMEbus made it particularly attractive as an instrumentation platform. The tremendous popularity of GPIB too made it attractive as a model for device communication and instrument control protocols. The VXIbus specification adds the standards necessary to combine the VMEbus with GPIB to create a new, modular instrumentation platform that can meet the needs of future instrumentation applications.
VXI brings the following benefits to instrumentation users:
The baseline VXI hardware specifications are a mandate for interoperatibility between hardware products from different vendors. These specifications cover mechanical and environmental requirements such as module sizes, mainframe and module cooling, and EMC compatibility between modules, as well as automated system initialization and backplane communication protocols. The VXIplug&play Systems Alliance builds on these baseline specifications to address the system as a total with the goal of having the user up and running in “five minutes or less.” building a system based on open industry standards means that you elect components for your system based on your requirements, regardless of vendor. Open standards too ensure that once your system is built, your investment will continue to pay dividends well into the future.
Both the VXIbus Consortium and the VXIplug&play Systems Alliance remain strong, active organizations committed to maintaining VXI as an open, multivendor technology and increasing its ease of exhaust and end-user success. In fact, many of the largest instrument suppliers in the world are members of both organizations, including National Instruments, GenRad, Hewlett-Packard, Racal Instruments, and Tektronix. With VXIplug&play, you are assured that components from different vendors travail reliably in the same system. Members of the VXIbus Consortium and the VXIplug&play Systems Alliance indulge in combined their expertise to develop technically sound standards for both hardware and software, bringing the entire industry into a unique generation of instrumentation – a generation that stresses ease of exhaust and open systems without sacrificing flexibility or performance.VXIbus Mechanical Configuration
Physically, a VXIbus system consists of a mainframe chassis that has the physical mounting and backplane connections for plug-in modules, as shown in pattern 1. The VXIbus uses the industry-standard IEEE-1014 VMEbus as a basis architecture to build upon. As shown in pattern 2, VXI uses the plenary 32-bit VME architecture, but adds two board sizes and one connector. The P1 connector and the seat row of the P2 connector are retained exactly as defined by the VME specification. The VME user-definable pins on the P2 connector and the additional pins on P3, the third VXI connector, implement instrumentation signals between plug-in modules directly on the backplane.
The VXIbus specification includes packaging requirements, electromagnetic compatibility, power distribution, cooling, and airflow for VXIbus mainframes and plug-in modules. The modules are installed in the mainframe slots. LEDs, switches, test points, and I/O connections are accessible from the module front panel.Module and Mainframe Cooling
Airflow direction is from bottom (P3) to top (P1). Cooling requirements must live established for plenary modules and included in product specifications. These requirements must include an operating point of minimum airflow requirement. Mainframe suppliers must too provide similar information for their mainframes.EMC and Noise
The addition of a unique module to a VXIbus system must not humiliate the performance of any other module. The VXIbus specification includes near-field radiation and susceptibility requirements, which obviate one module from interfering with the operation of other modules. To befriend meet these requirements, the VXIbus module width was increased from the 0.8 in. VME requirement to 1.2 in., so that there is enough leeway for the module to live completely enclosed in a metal case for shielding. The metal cases connect to backplane grounds. Thus, you can exhaust existing VME boards in a VXIbus chassis, but not vice versa.
The VXIbus specification too has conducted-emissions and susceptibility requirements, which obviate any power supply noise from affecting the performance of a module. For far-field radiated emissions such as FCC and VDE, each module must not contribute more than its participate of the total. For example, in a mainframe that holds 13 modules, each module must not contribute more than 1/13 of the allowed total. Because of the want for extremely precise time coupling between modules using the backplane, it is necessary to minimize the noise and crosstalk on the backplane clock and trigger signal lines. The backplane is required to live a single, monolithic board across any one slot. The VXIbus specification has a tutorial section on how to design a backplane for low noise and elevated signal integrity.Hardware Registers
VXI modules must indulge in a specific set of registers located at specific addresses, as shown in pattern 3. The upper 16 KB of the 64 KB A16 address space are reserved for VXIbus devices. Each VXI device has an 8-bit ratiocinative address that specifies where its registers are located in this address space. A unique VXI system can indulge in up to 256 VXI devices. The ratiocinative address of a VXI device, which can live manually set or automatically configured by the system at startup, is analogous to the GPIB address of a GPIB device.Register-Based Devices
Because of the VXI configuration registers, which are required for plenary VXI devices, the system can identify each VXI device, its type, model and manufacturer, address space, and reminiscence requirements. VXIbus devices with only this minimum flat of capability are called Register-Based devices. With this common set of configuration registers, the centralized Resource Manager (RM), essentially a software module, can discharge automatic system and reminiscence configuration when the system is initialized.Message-Based Communication
In addition to Register-Based devices, the VXIbus specification too defines Message-Based devices, which are required to indulge in communication registers and configuration registers. plenary Message-Based VXIbus devices, regardless of the manufacturer, can communicate at a minimum flat using the VXI-specified Word Serial Protocol. When minimum communication is possible, higher-performance communication channels, such as shared-memory channels, can live established to pick handicap of the VXIbus bandwidth capabilities.Word Serial Protocol
The VXIbus Word Serial Protocol is functionally very similar to the IEEE-488 protocol, which transfers data messages to and from devices one byte (or word) at a time. Thus, VXI Message-Based devices communicate in a style very similar to IEEE-488 instruments. In general, Message-Based devices typically accommodate some flat of local intelligence that uses or requires a elevated flat of communication.
All VXI Message-Based devices are required to exhaust the Word Serial Protocol to communicate in a touchstone way. The protocol is called word serial, because if you want to communicate with a Message-Based device, you Do so by writing and reading 16-bit words one at a time to and from the Data In (write Data Low) and Data Out (read Data Low) hardware registers located on the device itself. Word Serial communication is paced by the bits in the response register of the device, indicating whether the Data In register is empty and whether the Data Out register is full. This operation is very similar to Universal Asynchronous Receiver Transmitter (UART) on a serial port.Commander/Servant Hierarchies
The VXIbus defines a Commander/Servant communication protocol so you can construct hierarchical systems using conceptual layers of VXI devices. This structure is fancy an inverted tree. A Commander is any device in the hierarchy with one or more associated lower-level devices, or Servants. A Servant is any device in the subtree of a Commander. A device can live both a Commander and a Servant in a multiple-level hierarchy.
A Commander has exclusive control of the communication and configuration registers of its immediate Servants (one or more). Any VXI module has one and only one Commander. Commanders communicate with Servants through the communication registers of the Servants using the Word Serial Protocol if the Servant is a Message-Based device, or by device-specific register manipulation if the Servant is a Register-Based device. Servants communicate with their Commander by responding to the Word Serial commands and queries from their Commander through the Word Serial protocol if they are Message-Based, or by device-specific register status if they are Register-Based.Interrupts and Asynchronous Events
Servants can communicate asynchronous status and events to their Commander through hardware interrupts or by writing specific messages (signals) directly to their Commander's hardware Signal Register. Nonbusmaster devices always transmit such information via interrupts, whereas devices that indulge in busmaster capability can either exhaust interrupts or route signals. Some Commanders can receive signals only, whereas others might live only interrupt handlers.
The VXIbus specification contains defined Word Serial commands so that a Commander can understand the capabilities of its Message-Based Servants and configure them to generate interrupts or signals in a particular way. For example, a Commander can instruct its Servants to exhaust a particular interrupt line, to route signals rather than generate interrupts, or configure the reporting of only unavoidable status or oversight conditions.
Although the Word Serial Protocol is reserved for Commander/Servant communications, peer-to-peer communication between two VXI devices can live established through a specified shared-memory protocol or by simply writing specific messages directly to the signal register of the device. Slot 0 and the Resource Manager
The leftmost slot of a VXI chassis has special system resources such as backplane clocks, configuration signals, and synchronization (trigger) signals and therefore must live occupied by a device with VXI “Slot 0” capabilities. The VXI Resource Manager (RM) function, essentially a software module, can reside on any VXI module or even on an external computer. The RM, in combination with the Slot 0 device, identifies each device in the system, assigns ratiocinative addresses, reminiscence configurations, and establishes Commander/Servant hierarchies using the Word Serial Protocol to accord Servants to the Commanders in the system. After establishing the Commander/Servant hierarchy, the RM issues the inaugurate normal Operation Word Serial command to plenary top-level Commanders. During normal system operation, the RM may too halt the system and/or remap the hierarchy if necessary.Three Ways to Control a VXI System
System configuration is divided into three categories. The first nature of VXI system consists of a VXI mainframe linked to an external controller via the GPIB. The controller talks across the GPIB to a GPIB-VXI interface module installed inside the VXI mainframe. The GPIB-VXI interface transparently translates the GPIB protocol to and from the VXI Word Serial protocol.
The second configuration involves a VXI-based embedded computer. The embedded computer is a VXI module that resides inside the VXI mainframe and connects directly to the VXI backplane. This configuration offers the smallest physical size for a VXI system as well as performance benefits due to direct connection to the VXI backplane.
The third configuration uses a high-speed MXIbus link from an external computer to control the VXI backplane. The external computer operates as though it is embedded directly inside the VXI mainframe. This configuration is functionally equivalent to the embedded method, except that it has the flexibility for exhaust with a wide variety of computers and workstations.VXI Bus Interface Software
One of the most considerable considerations when selecting a VXI system is software. Software is the key to developing successful systems based on the VXIbus. There are many programming languages, operating systems, and application development environments (ADE) to elect from when building a VXI system. It is considerable to form the perquisite decisions to realize plenary of the advantages that VXI has to offer, while minimizing your development costs now and in the future.
Your software decisions not only feel overall system performance and system capability, but too development time and productivity. You should elect tools that indulge in complete debugging capability and that travail with the most Popular operating systems and programming languages. If you elect to program your VXI system using a touchstone language such as C, C++, Basic, ADA, or ATLAS, you should realize that touchstone programming languages Do not Come with built-in VXI capability. Rather, VXI capability is added through a VXI bus interface software library. This software component is very important, because it affects the choice of VXI computer hardware, operating system, programming language, and ADE.Industry-Wide Software Standards
As a step toward industry-wide software compatibility, the VXIplug&play alliance developed one specification for I/O software – the Virtual Instrument Software Architecture (VISA). The VISA specification, VPP-4.1, defines a next-generation I/O software touchstone not only for VXI, but too for GPIB and serial interfaces. With the VISA touchstone endorsed by more than 50 of the largest instrumentation companies in the industry including Tektronix, Hewlett-Packard, and National Instruments, VISA unifies the industry by facilitating the development of interoperable and reusable software components able to stand the test of time. Before VISA, there were many different commercial implementations of I/O software for VXI, GPIB, and serial interfaces; however, nobody of these I/O software products were standardized or interoperable.
The VISA touchstone lays the foundation and provides a unified migration path for industry-wide software compatibility. One of the most notable benefits of VISA is its capacity to significantly reduce the time and application involved in programming different I/O interfaces. Instead of using a different API devoted to each interface bus, you can exhaust the VISA API regardless of whether your system is controlled by GPIB, VXI, or a GPIB-VXI.
With the vast number of choices in instrumentation and software now available, most users Do not want to live locked into a specific vendor for their systems. Instead, they would prefer the freedom to select the best instruments and software available from multiple vendors and indulge in it plenary travail together with minimal effort. The IEEE 488.1 and IEEE 488.2 standards (for GPIB) and the IEEE 1155 touchstone (for VXI) ensured that the hardware would live interoperable, but this approach was not taken for the software. Therefore, the ideal unique driver architecture should live a touchstone adopted by as many of the major vendors as possible. Then you could live assured that any code written for your instrument is portable across controller vendors as well as operating systems. This is exactly what the VXIplug&play Systems Alliance has done with VISA.MXI Tutorial
This section contains an overall introduction to MXI.MXIbus Overview
The MXIbus is a powerful, high-speed communication link that interconnects devices using a springy cabling scheme. Derived from the VMEbus, MXI provides a high-performance course of controlling VXI systems using commercially available desktop computers and workstations. National Instruments developed and published the MXI specification and released it as an open industry touchstone in 1989. In 1995, National Instruments introduced MXI-2, which offers even higher performance.
An MXIbus system configuration combines the performance benefits of a custom embedded VXI computer with the flexibility and availability of general-purpose computers. The MXIbus system configuration uses the high-speed MXIbus cable to connect an external computer directly to the VXI backplane. With the MXIbus, you can locate the computer directly next to the VXI mainframe, or up to 20 meters away. Using the MXIbus, you can easily add other VXI mainframes, and exhaust the plug-in slots in the external computer for GPIB-control, plug-in DAQ boards, or other peripheral adapter cards.
For instrument control, MXI complements high-speed platforms such as PCI by harnessing their high-throughput potential. PCI-based desktop PCs compete with the most advanced computer workstations to provide a low-cost platform that delivers superior performance. You can exhaust low-cost desktop computers to control sophisticated VXI instrumentation without sacrificing performance or control. More importantly, as unique desktop computers incorporate the latest technology including faster, more capable microprocessors and RAM, you can easily upgrade your VXI system as these newer and faster computers emerge to immediately garner increased VXI performance gains. Thus, a PCI-based MXI-2 solution such as their VXI-PCI8000 gives you excellent performance now with headroom for the future.A unique Generation of VXI Connectivity
Many VXI users migrate from GPIB-based systems. As a result, the National InstrumentsGPIB-VXI is a Popular course to control VXI instruments from a GPIB controller. An increasingly Popular course to control VXI, however, is to exhaust a custom VXI computer that plugs directly into the VXI mainframe, such as the National Instruments VXIpc™ and VXIcpu™ series of embedded VXI computers. This embedded approach is technically attractive because the computer communicates directly with the VXIbus and is tightly coupled to the instruments.
Although an embedded computer is very powerful, custom VXI computers cannot possibly sustain pace with the general-purpose computer market. In the final decade, specialized instrument controllers indulge in rapidly declined. General-purpose PCs and workstations, with their vast array of software and accessories, indulge in revolutionized the industry. By using general-purpose computers, the instrumentation industry directly benefits from the billions of R&D dollars spent each year in the common computer market.
Most VXI users would prefer to exhaust an industry-standard computer provided by a computer vendor rather than a VXI-specific computer provided by an instrument vendor. In fact, for VXI to truly become the platform for the next millennium, it must align itself with the powerful common computer market. Then VXI can pick handicap of the billions of dollars being spent and bring this investment to abide on the needs of the instrumentation community. VXI must live able to pick plenary handicap of industry-standard PCs with PCI, EISA, and ISA, as well as workstations from Sun, HP, and others. VXI too must indulge in a transparent mechanism for extending to multiple mainframes, and a course to accommodate instruments that cannot physically fitting on a VXI module. MXIbus meets each of these needs.The requisite for MXIbus
Today’s market demands that you add value to test and measurement systems. You requisite modular testing systems that can evolve with technological innovations in the industry. You want increased data throughput and the utmost in computing power; you want flexible, high-speed connectivity between multiple VXI/VME mainframes; and you want to live able to sustain up with innovations in PC and workstation technology. Today, sophisticated I/O architectures such as PCI are accelerating data throughput – who knows what tomorrow may hold. How can you pick these benefits both now and in the future? The answer is MXI.
MXI provides you with a solution that combines the performance benefits of an embedded VXI computer with the flexibility of a general-purpose desktop computer. Their VXI-PCI8000 controller and their next generation MXI-2 provides you with an ultra high-performance VXI connectivity solution that can meet your needs both today and well into the future. Although traditional connectivity solutions indulge in proved to live very effective, they too indulge in proved to live the bottleneck in VXI test systems because the software protocol overhead associated with these methods significantly reduced the achievable throughput on the link. Using MXI, this bottleneck is eliminated altogether because MXI devices are connected at the hardware flat by mapping each physically divide system into a shared reminiscence space. Physically divide devices transparently participate resources through simple reads and writes to the arrogate address in memory. Their next generation MXI-2 products enhance VXI connectivity by defining a unique memory-mapped backplane-on-a-bus that can transparently extend bus-level I/O, VXI triggering, interrupts, and systems clocks between systems. You can now exhaust a unique cable to conveniently participate trigger and timing information between mainframes in a multiple mainframe configuration. The MXI 2.0 specification too defines a synchronous data transfer mode that increases MXIbus throughput for block data transfers. From a system standpoint, this means that MXI throughput rates can easily sustain up with the data rates of high-performance computers, peripherals, and instrumentation . From a user standpoint, this translates to increased performance and reduced time to test. By choosing a PC-based MXI approach, you are choosing to add value to your VXI instrumentation systems by using technologies that form sense from both a cost and performance perspective.MXIbus Applications
You can exhaust MXIbus for a variety of applications. You can interface industry-standard desktop computers to VXIbus or VMEbus; you can create multiple chassis configurations using their VXI-MXI or VME-MXI extenders; and you can integrate VXI and VME chassis into the same test system.
Figures 5 and 6 demonstrate two common configurations with MXIbus.How Does MXIbus Work?
MXIbus is a common purpose, 32-bit multimaster system bus on a cable. MXI interconnects multiple devices using a springy cabling mode similar to GPIB, but uses a hardware memory-mapped communication scheme that eliminates the software overhead. MXI devices can directly access each other’s resources by performing simple read and writes to arrogate address locations. The unique MXI-2 touchstone expands on the MXI-1 touchstone by exporting plenary VXI backplane signals such as VXI-defined trigger lines, interrupt lines and system clocks, in addition to the touchstone MXIbus signals directly to the cabled bus. MXI-2 users can accomplish censorious timing and synchronization tasks between up to eight, daisy-chained MXI devices.
MXI device connectivity is accomplished at the hardware level. The MXI cable serves as a transparent link that interconnects multiple MXI devices. These devices are interlaced by mapping together portions of their individual address spaces so that a system composed of multiple devices behaves as a unique system with a shared address space. pattern 7 shows the MXIbus hardware memory-mapped communication. The immediate capitalize of this approach is increased data throughput due to the absence of software overhead.
Each MXIbus hardware interface has address window circuitry that detects internal (local) bus cycles that map out to the MXIbus. In addition, this circuitry too detects external (remote) MXIbus cycles of connected devices whose addresses map into the shared reminiscence space of the overall system. When a hardware write or read occurs with an address that maps across MXI, the MXI hardware interlocks the bus cycle between the devices via the MXIbus. This hardware scheme is the same as that used by embedded VXI controllers.
MXIbus signals include 32 multiplexed address and data lines with parity, address modifiers for multiple address spaces, single-level multimaster prioritized bus arbitration, a unique interrupt line, a bus oversight line for handling timeouts and deadlock conditions, and handshake lines for asynchronous operation. Data transfers of 8, 16, and 32 bits are possible, as well as invisible read/write operations and integrated block-mode transfers. With synchronous MXI, the MXI-2 product line can achieve burst data rates as elevated as 33 Mb/s, and sustained throughput rates exceeding 20 Mb/s, regardless of the length of the MXI-2 cableMXIbus Cables
A unique MXI cable can live any length up to 20 m. Up to eight MXI devices can live daisy chained on a unique MXI cable length. If multiple MXI devices are daisy chained together, the total cable distance must live no more than 20 m. The MXI-1 cable is a flexible, round cable similar to a GPIB cable (about 0.6 in. in diameter). Internally there are 48 single-ended, twisted-pair signal lines. MXI-2 features an improved cabling scheme that uses a unique double-shielded cable between plenary devices, and a unique high-density, high-reliability 144-pin connector per device. In this fashion, plenary MXI-2 devices participate not only the MXIbus itself, but too the VXI-defined trigger lines, interrupt lines, systems clocks, and other signals that were available on MXI-1 products as an optional second connector and cable (INTX). MXI-1 products exhaust an MXI-1 cable between devices, and an optional INTX cable to participate trigger/timing information between mainframes in a multiple mainframe configuration. MXI-2 eliminates the requisite for an additional INTX cable in your system. Because of the cable differences, you cannot blend MXI-1 and MXI-2 products in the same system. Both MXI-1 and MXI-2 exhaust double shielding with an aluminum mylar shield as well as a copper braid shield to eradicate any EMI problems, and both cables meet the National Electric Code (NEC) CL2 fire safety code. The stacking depth of two daisy-chained MXI cables is approximately 3.3 in.
MXI is essentially a backplane bus in a cable. Each MXI signal line is twisted with its own ground line. plenary MXI signal lines are matched impedance to minimize signal skew and reflections. Stub lengths no more than 4 in. off the mainline interconnection minimize reflections due to impedance discontinuities. Termination networks, configured with onboard jumpers, are located at the first and final MXI devices to minimize reflections at the ends of cables.
MXI uses state-of-the-art, single-ended, trapezoidal bus transceivers to reduce noise crosstalk in the transmission system. Designed specifically for driving backplane bus signals, these transceivers indulge in open-collector drivers that generate precise trapezoidal waveforms with typical soar and Fall times of 9 ns. The trapezoidal shape, due to the constant soar and Fall times, reduces noise coupling (crosstalk) on adjacent lines. The receiver uses a lowpass filter to remove noise and a high-speed comparator that recognizes the trapezoidal-shaped signal from the noise.Performance Issues MXIbus Performance
It is often difficult to understand how a performance specification for a unique component relates to the overall performance of your system. In the case of MXI, it is considerable to understand not only the performance issues associated with the MXI link, but too the devices that communicate across the link. MXI works fancy an embedded computer, using a direct hardware memory-map to eradicate software overhead between your computer and the VXIbus or VMEbus. Both MXI and embedded VXI computers can exhaust shared-memory communication protocols and direct register accesses for potentially dramatic performance improvements over GPIB. If your VXI instruments themselves Do not exhaust these capabilities, however, your system performance using MXI or an embedded computer may live no higher than a GPIB-controlled VXI system.
There are several factors to regard when comparing an MXI-equipped computer to an embedded computer. An MXI-equipped computer is functionally equivalent to an embedded computer. In fact, application software developed on a MXI computer using NI-VXI/VISA bus interface software can easily flee on an embedded computer and vice versa. There are subtle hardware timing differences, but there is no dramatic performance inequity due to architecture. MXI, for example, can pick roughly 100 ns more to discharge a unique VXI read or write than an embedded computer, because the MXI signals must propagate down the MXI cable at 10 ns/m. This subtle detail is measured in ns, and is negligible compared to the other factors that feel your system performance, such as the execution hurry of your application software or your instruments.
Often, the most considerable performance issue to regard when evaluating a computer for your system is the performance of the processor itself. Most applications spend much more time computing, displaying, or performing disk I/O than actually performing I/O across the VXIbus or VMEbus. Current external MXI computers are more than four times as mercurial as the fastest embedded VXI computer. In addition, because of the physical space constraints of embedded computers, external computers often indulge in much more sophisticated architectures with faster processors, cache RAM, faster disk drives, and other benefits. Raw computing power can live the unique most considerable consideration for the performance of your system.Data Transfer Rates
A common benchmark for VXI computers is the block Data Rate. This benchmark is smooth for vendors to seclude and measure under ideal conditions. It is considerable to understand what block Data Rate means to your application. block Data Rate is the rate at which you can whisk a large block of data to or from reminiscence on an ideal VXI device using back-to-back VXI transfers. It does not measure how mercurial the computer can process the blocks of data or store them to disk once they are moved, or whether your instruments themselves can actually match that data rate. Most applications are not limited by the block Data Rate of the VXI interface hardware, but rather by the total time required to both whisk and ply the data, or by the rate at which the instruments themselves can generate or accept the data.
Block Data Rate is smooth for vendors to specify, but often difficult for users to relate to overall system performance. It is only one of many elements that feel the actual throughput of your system. For example, block Data Rate does not argue the processing power of your computer or the performance of the instruments themselves. In addition, a benchmark for block Data Rate does not measure how mercurial you can control instruments using VXI Word Serial Protocol or random VXI reads and writes. The hurry for Word Serial communication and random VXI reads and writes is relative on the hurry of the processor and the particular VXI instruments.Local Performance
The MXIbus does not humiliate the performance of the devices connected to it. Each MXI device can operate internally at plenary hurry in parallel with other MXI devices. Because MXIbus is a accurate system bus with multimaster arbitration, the only time MXI devices must synchronize their operation is when they discharge transactions that map across the MXIbus. When one MXI device performs a read or write that maps to a remote MXI device, the MXI hardware on both devices interlocks the bus cycle across the MXIbus to accomplish the transfer.MXI – An Open Standard
The MXIbus specification was developed by National Instruments and announced in April 1989 as an open industry standard. A VXIplug&play core technology, MXIbus has been endorsed by the entire VXIplug&play Systems Alliance, including Tektronix, Hewlett-Packard, Racal Instruments, and GenRad. Because MXI is an open touchstone documented with a comprehensive specification, anyone can develop products that will live integrated into an MXI controlled system.
Channel partners are hailing the availability of VMware Cloud Foundation (VCF) on Dell EMC’s leading hyper-converged infrastructure VxRail solution as a “game-changer” that will enable faster adoption of hybrid cloud.
“This is a game-changer for VMware. You’re talking about VMware Cloud Foundation and it has NSX, it has the vSAN portfolio – that’s a accurate multi-cloud operating system,” said Vinu Thomas, chief technology officer at Presidio, a New-York-based solution provider powerhouse and top global VMware partner. “So it would live noteworthy if you could actually do VMware Cloud Foundation on top of hyper-converged because what a hyper-converged system does at the End of the day, is it brings those public cloud features, functionally, agility and scalability on to the private cloud. … Dell and VMware coming together makes absolute sense in bringing VxRail running VCF inside the data seat that can then extend to VMware on AWS, and now you indulge in a accurate multi-cloud operating system. It’s just genius to remark how they can bring this plenary together and form one operating system for the multi-cloud world.”
For the first time, VMware Cloud Foundation is becoming available on Dell EMC’s market hyper-converged VxRail solution beginning in April. The unique offering gives customers the industry’s first jointly engineered, hybrid cloud infrastructure stack integrated with VMware’s architecture, according to Chad Dunn, vice president of Hyper-Converged Infrastructure product management for Dell EMC.
[Related: Dell Teases unique Consumption-Based Pricing Offerings For Partners]
“We believe this is the simplest and fastest course to obtain to a VMware hybrid cloud,” said Dunn in an interview with CRN.
“The mandate they were given from [Dell Technologies CEO] Michael Dell, [vice chairman, Products and Operations, Dell EMC] Jeff Clarke and [VMware CEO] Pat Gelsinger is, ‘When they Do things with VMware and Dell EMC, they want it to live first and best no matter what they do,” said Dunn. “We’re leveraging VxRail APIs that aren’t available to anybody else that really expose the value added capabilities in VxRail to VMware Cloud Foundation. That full-stack integration of lifecycle management of plenary of the hardware and software components at a cluster level, this extends those capabilities via API into Cloud Foundation, it extends their southbound APIs into Dell networking switches to automate their deployment. We’ll continue to expand that ever further.”
With the unique VCF on VxRail, Dell EMC and VMware are aiming to deliver the fastest and easiest path to deploy a hybrid cloud through a fully-integrated hybrid cloud platform.
The unique VCF on VxRail will include Dell EMC and VMware jointly-engineered features aimed to simplify and streamline operations, while delivering end-to-end lifecycle management through an automated hardware through software. Delivering a unified user experience, VMware Cloud Foundation on VxRail is lifecycle managed as one automated, turnkey hybrid cloud experience, greatly reducing risk and increasing IT operational efficiency, according to Dunn.
Josh Lee, director of sales for Nanuet, N.Y.-based Dell Technologies confederate VirtuIT Systems, said the unique offering is “a noteworthy thing” for the channel.
“It proves that if you’re a VMware customer, Dell EMC is the No. 1 confederate to indulge in for a hardware platform,” said Lee. “Most of the customer we’re talking too are looking at multi-cloud or hybrid cloud. Nobody else in the hyper-converged space can whisk from the low mid-tier and SMB market to as elevated as the enterprise with this integration saying, ‘Hey they can Do VMware Cloud Foundation, on-premise with an integrated solution fully supported by the OEM. And it gives you the capacity to indulge in a multi-cloud environment out to whatever public cloud confederate you’re using that certified.’”
VMware has made architectural updates to VCF that that will pair well with core VxRail functionality such as networking flexibility enabling Dell EMC integration benefits, as well as deployment options ranging from appliance to integrated rack offerings. Another example, is the synchronous release of VxRail and VMware software updates so the latest HCI and cloud software benefits are in customers’ hands sooner.
Dunn said VCF for VxRail opens up unique customer opportunities and services for channel partners. “Obviously there’s a ample services component to this. If you ascertain at the deployment of a VMware validated design, which they indulge in a lot of customers are doing, there’s a wealthy services break there for partners,” he said.
VMware Cloud Foundation on VxRail is a major illustration of the power of the Dell Technologies family of businesses, which includes Dell, Dell EMC, VMware, Pivotal, RSA, Virtustream and SecureWorks.
“When they obtain that mandate from Michael Dell that says, ‘We must always live first and best in terms of VMware, Pivotal, etc. integration” – they pick that very seriously,” said Dunn. “If you ascertain at the portfolio of Dell Technologies, they indulge in the industry leading virtualization platform in VMware. They indulge in an industry leading hyper-converged infrastructure product with VxRail built on the industry leading server platform, which is PowerEdge, too with industry leading platform in container and service offerings from Pivotal – you really obtain that total end-to-end portfolio. They really can champion you from mouse pads up to cloud infrastructure.”
