The Linux-primarily based unlock 6.0 of the UC platform offers users freedom to beget expend of hardware from Dell, Hewlett-Packard or IBM. The CS 1000 v. 6.0 additionally integrates with Nortel’s contact core answer, Contact heart 7.0. moreover new is the MG 1010, a functions gateway for centralized communications app provisioning and augmented SIP support.
at the side of the brand new release, Nortel moreover debuted new IP handsets and announced enhancements to its conferencing utility.related

newsMicrosoft and Nortel current Alliance Roadmap
the two businesses first announced their collaboration remaining summer season.
The street map contains three new joint solutions “to dramatically extend enterprise communications by route of breaking down the obstacles between voice, e mail, immediate messaging, multimedia conferencing and different forms of conversation,” in line with a statement by means of both firms.
additionally covered in the announcement are eleven new implementation functions from Nortel and the opening of greater than 20 joint demonstration facilities where clients can flavor the technology, the statement continued.
additionally, both businesses observed they acquire got signed agreements with dozens of customers, and acquire developed a “pipeline of tons of of potentialities who are looking to recognize the benefits of unified communications.”
From Microsoft's perspective, it is total a participate of the enterprise's long-term play to merge every kindly of communications and messaging into a sole framework. A year ago, the industry introduced that it became merging its trade Server group with its precise-Time Collaboration (RTC) community, and that it had begun to suppose of both applied sciences comprising a "platform."
the new neighborhood was named the Unified Communications community (UCG) and resides in Microsoft's company Division. The theory for the brand new neighborhood emanated from a vision of adding continuity to a myriad of communications gadgets, technologies and modes -- from e mail and quick messaging to Voice over internet Protocol (VoIP), audio/video and net conferencing -- in a unified method.
The three new joint options announced by means of the alliance this week are named Unified Communications built-in department, Unified Messaging, and Conferencing.
When it's available within the fourth quarter, UC built-in department will accommodate Nortel and Microsoft know-how on a sole piece of hardware that supplies VoIP and unified communications in far off offices.
Coming a minute earlier within the 2d quarter, Unified Messaging will goal to simplify client deployments, native session initiation protocol (SIP) interoperability between the Nortel communique Server one thousand and Microsoft change Server 2007. The reply comprises Nortel expert features for design, deployment and support.
also coming in the fourth quarter, Conferencing will lengthen Nortel Multimedia Conferencing to Microsoft office Communicator 2007. It goals to supply a sole client journey consistent across purposes similar to voice, immediate messaging, presence, and audio- and videoconferencing.
This 12 months, the agencies moreover device to lengthen their existing unified communications solution — a unified computer and gentle cellphone for VoIP, email, quick messaging and presence — to the Nortel conversation Server 2100, a provider-grade industry telephony product aiding as much as 200,000 clients on a sole gadget, in response to industry statements.
As for the highway map, both organizations acquire outfitted greater than 20 joint demonstration facilities in North the us, Europe and Asia, with more than one hundred further centers scheduled to open by midyear.
Nortel has moreover introduced 11 core integration capabilities to serve consumers build, deploy and assist joint unified communications options, including end-to-end project administration. Nortel claims it has already expert more than 2,200 VoIP consultants to carry these services and may add extra as deployment ramps up.
Stuart J. Johnston has lined technology, certainly Microsoft, due to the fact February 1988 for InfoWorld, Computerworld, recommendation Week, and notebook World, in addition to for industry Developer, XML & net functions, and .web magazines.
Avaya day after today will present a road map that indicates how its shoppers – in unavoidable its newly minted Nortel shoppers -- can poke to unified communications applied sciences without ripping out existing equipment.

the upward push and descend of Nortel
The device mainly addresses how the enterprise will win rid of overlap between its personal and Nortel's product lines, every now and then favoring Avaya technology, sometimes Nortel's, within the areas of unified communications, contact centers, tiny and midsize groups as well as network infrastructure. at the same time the device allows for cost discounts by route of SIP trunking so that they can let customers forward voice and information over one pipe instead of numerous lines and other decreased fees by route of centralizing administration of company mobilephone systems, Avaya says.
The internet influence, says Alan Baratz, senior vice chairman and president for world verbal exchange options at Avaya, is extended capabilities, decreased expenses and less disruptive change.
Promising to achieve a significant a participate of this in the yr is an aggressive purpose that may additionally galvanize Nortel purchasers hunting for a advantageous looking route to unified communications, says Zeus Kerravala, an analyst with the american neighborhood.
delivering on time is crucial as a result of former Nortel valued clientele that need to aggressively pursue UC might not wish to wait and wait, he says. Avaya CEO Kevin Kennedy's time at Cisco may additionally advocate because of that rival's adventure in buying other businesses and integrating them smoothly, he says.
"every Nortel client is going to acquire a competitive seller attempting to create a path to their personal unified communications answer," he says. Fumbling might not be deadly, Kerravala says, however might add up to a loss of the magnificent 25% marketshare he says Avaya has accumulated in telephony.
As for the specifics of the street map, including an essential SIP layer into the communications hierarchy will be completed by means of Avaya air of secrecy, the company's SIP-based mostly communique application platform that may be sandwiched between communications infrastructure - comparable to PBXs - and capabilities - comparable to voice, video, messaging, conferencing and mobility.
With charisma in place, legacy Avaya and Nortel PBXs will interoperate with SIP-based mostly VoIP equipment. So Nortel communique Server a thousand IP PBX with aura layered on precise of it could interface with SIP-based mostly telephones plugged into the aura aspect of the network. total the telephones would acquire CS 1000 aspects and the equal button sequencing with the objective to navigate those facets, Baratz says. additionally, legacy Nortel phones can be plugged into the air of secrecy facet of the network.
This movement will in the reduction of impregnate of adopting unified communications since it reduces the want for changing PBXs and phones as well because the cost of retraining quit clients in how new phones work, he says.
The device requires application integration and it won't occur overnight, Baratz says, but it surely should be achieved with the aid of the quit of this year, doubtless in November, Baratz says. Nortel's enterprise Communications outfit manager will be integrated into air of secrecy, as will Nortel's Agile Communications ambiance (ACE), which permits infusing functions with communications capabilities.
The alterations might be distributed as application improvements to current charisma valued clientele.
This routine is never striking, Kerravala says, because aura was designed to embrace an SIP-based gear, no rely who the supplier. Integration with Nortel device should silent be less complicated because Avaya owns both units of assets so can beget their SIP implementations appropriate. specifications-compliant implementations of SIP can fluctuate ample that they conclude not interoperate, he notes.
within the belt of contact facilities, Avaya will enhance Nortel Contact middle application after which integrate it into its current line. Over the subsequent six to 9 months, further revisions of Nortel's Contact middle will achieve together it to become the Avaya providing for midsize businesses instead of Contact middle specific.
After that, the contact core utility from Nortel can be evolved to incorporate architectural elements from both Nortel and Avaya traces, then additional developed to scale to industry proportions. These two revisions will acquire six to 9 months every. At that aspect the utility will become an upgrade to supplant Avaya's excessive-conclusion Contact heart Elite.
Baratz says that even earlier than the acquisition of Nortel, Avaya mentioned that Nortel's midsize contact heart was more suitable. "It changed into very near the finest product they wanted," he says.
Avaya plans to slowly prick back the variety of telephony alternate options purchasable for tiny and midsize organisations. It plans to convey legacy Avaya companion and vital 5 key methods in addition to Nortel Norstar systems beneath the umbrella of its IP office equipment.
IP office will be developed to aid Norstar methods and Nortel company Communications manager hybrid PBXs, and a number of years down the road will change them. but in the meantime, Norstar and BCM will abide available. "Nothing abrupt is going to betide here," Baratz says.
Nortel's utility Communications system SIP appliance will be participate of the portfolio as is. There is no analogous Avaya product.
Nortel brought along a portfolio of switches, network safety and instant gear for which Avaya has no competing gadget. Avaya plans to promote these items and strengthen them to interoperate more closely with its unified communications infrastructure, Baratz says.
as an example, the instant outfit and switches may moreover be tweaked to supply extra complete statistics about the presence of cellular worker's. at the minute they present whether an individual is accessible by the expend of voice. With superior integration they could vow that the particular person is attainable on a mobile machine and the spot it is determined, he says.
but Kerravala says that Avaya needs to enhance its apparatus to be aggressive with different infrastructure companies characteristic for function, no longer just to acquire switches and routers that extend communications. He says Avaya owns 5% of the infrastructure market through virtue of buying Nortel and should let it function as a sunder division at once taking up Cisco, HP and others. "it be a large installed base," he says.

Single-pair Ethernet and IETF/IEEE standards are spurring drudgery on a harmonized network based on Ethernet, Internet Protocol, and the related open ecosystem.
At the recent ODVA technical conference, the key takeaway was that standards are emerging that will leverage Industrial Ethernet network convergence and edge devices to accelerate the migration from traditional bailiwick buses to Industrial Ethernet. New technologies including sole Pair Ethernet, Time Sensitive Networking, and constrained node devices/networks are seen as potentially impacting the expend of Industrial Ethernet—in conjunction with EtherNet/IP—as they poke into the future.
Manufacturing applications could capitalize from constrained EtherNet/IP in four key areas: in-cabinet components, on-machine components, process automation, and low-power wireless solutions. (Image source: ODVA)
Ethernet, IP, and Open Ecosystem
The argument is that, while Industrial Ethernet has exhibited rapid growth in recent years, bailiwick buses and sensor networks are silent widely used. In addition, many potential network nodes remain hardwired. However, quit users understand and will search the advantages of a harmonized network based on Ethernet, Internet Protocol (IP), and the related open ecosystem. Potential benefits comprise reduced complexity and cost by minimizing the expend of gateways and eliminating hardwiring, along with improved optimization and maintenance using cloud connectivity and analytics.
But unfortunately, there are moreover barriers to the sole network vision. So while usage of a mingle of EtherNet/IP, bailiwick buses, and hardwired nodes continues, open standards backed by IETF and IEEE are offering new alternatives. According to the technical paper, “Enhancements to EtherNet/IP for Constrained Devices and Networks,” which was presented at the ODVA conference: “IoT opportunities led IETF to create IP-stack optimizations for constrained devices and networks (RFC 7228). Enhancements are applicable to both low power wireless (6TiSCH) and wired networks, eliminating TCP overhead (UDP-only), compressing messages (6LoWPAN), expanding the address space (IPv6), optimizing security (OSCORE), and shrinking the Web server (CoAP).”
The sentiment is that “the resulting sole Pair Ethernet suite offers reduction in wiring, node cost, size, and power consumption, delivering communication and power over a sole pair.”
Three key markets are driving volume, providing the occasion for industrial users to leverage these technologies. This includes expend of sole pair Ethernet in automotive industry applications, structure automation relish smart LED lighting, and process automation.
Barriers to the sole Network Vision
Key barriers to this vision are that many edge devices are constrained by low cost, size (small photo-sensors, for example), or power (densely packed or battery powered). Additional concerns comprise wiring costs and a requirement for long cable distances.
IETF and IEEE Standards
IETF has introduced related standards and drafts for constrained nodes and networks that are seen as potential structure blocks for creating more effectual solutions. Key technical points include: elimination of TCP overhead (UDP-only); compression of message headers; expansion of the address space (IPv6); optimization of security (OSCORE); and shrinking the web server (CoAP).
The IEEE has moreover been working to develop a family of sole Pair Ethernet (SPE) standards, enabling communication and optional power over a sole pair to serve address issues with wiring, node cost, size, and power consumption challenges.
A new gauge (IEEE P802.3cg) with an estimated completion date late in 2019 aims to introduce a pair of 10 Mbit/s SPE PHYs targeting constrained applications. 10BASE-T1L focuses on process automation instruments by offering distances to 1000 meters, intrinsic safety compatibility, and advocate for legacy wiring. In contrast, 10BASE-T1S is focused on replacing the CAN, CAN FD, MOST, and FlexRay protocols in automotive applications, along with hardwired components in industrial automation control cabinets.
Constrained EtherNet/IP Explorations
New potential application areas for EtherNet/IP at the network edge are constrained applications for bailiwick devices with a focus on process automation, low power wireless, in-cabinet components, and on-machine components.
A number of options to reduce cost, size, and complexity are being explored. EtherNet/IP currently requires the expend of both TCP and UDP in the network stack of a device. Using UDP only, for example, could result in a substantial reduction in stack complexity and messages. In typical CIP applications, encapsulation and CPF headers create significant overhead in EtherNet/IP messages. Low power wireless networks, such as IETF 6TiSCH, acquire constrained packet size, which is not able to carry the existing encapsulation header in a sole wireless packet.
Current EtherNet/IP communication does not advocate constrained device and network requirements. But there is a proposal to develop a constrained EtherNet/IP communication profile.

Digital storage is an famous component in the Open Compute Project and there were many announcements and presentations focusing on digital storage at the 2019 OCP Summit. Digital storage is an famous enabler of advanced applications such as machine learning training and inference accelerators for putting AI to work. They will travel over some of the presentations and announcements from the 2019 OCP Summit.
As Vijay Rao from Facebook discussed, for his company there is a substantial focus on using AI for video/image applications. He said that CPUs and GPUs are not enough that that custom accelerators are coming into wider use. The original Glacier Point v2 was an NVMe storage module for Yosemite. The original Glacier Point lucky six NVMe SSDs into the same profile factor that the Intel Twinlake accelerator modules lucky into. The v2 Glacier Point has 12-M.2 interfaces for a mingle of accelerators and SSDs in Yosemite 2.0. Using a mingle of processor (e.g. the Intel NNP I-1000) and storage M.2 modules, Facebook plans to expend Yosemite for compute, video and AI inference applications. The design below shows how Yosemite is achieve together.Image from OCP pinnacle Presentation
Vijay moreover displayed an image of upcoming neural networks and the dominating activities for these different. He pointed out that the OCP Angel’s Landing box with 8 CPUs was a learning module for recollection bandwidth and recollection capacity dominated machine learning workloads, while the Emerald Pool box is compute and communication dominated.
Nav Kankani and Vijayan Rajan from Facebook spoke about hardware and software co-design to achieve predictable IO latency. The design below shows their view of today’s storage/memory types—going from the core through cache layers, DRAM Flash, HDDs and Magnetic Tape.Image from OCP pinnacle Presentation
They moreover pointed out that as the density of NAND twinkle has increased the IOPS/TB has decreased. With less die per TB there is an extend in IO latency and therefore less predictable system latency as shown below.Image from OCP pinnacle Presentation
With the massive levels of sharding of data, fetching that data incurs a large fanout on the system backend resulting in reading from several servers and many different pieces of data from each server. The result is a wide degree of variability (e.g. asymmetry in read and write access patterns) in hyperscale workloads. Because of the amplification in user requests to backend requests the long tail latencies become more famous in overall performance than average latency. The more the user requests, the greater the probability of tall tail latency. Despite the unpredictable latency in the storage stack, a large-scale distributed system needs predictable latency. large scale distributed systems need predictable latency regardless of unpredictable latency in the storage stack (which exists).
In order to create this predictable system latency several things are done at the hardware layer including parallel operation paths, priority quest, and new device features such as write/erase suspends. One must moreover be able to insulate streams and VNMeSets, let maximum read recovery limits and find and maintain predictable latency modes.
At the software layer to optimize for predictable latency one needs to conclude shard management and rebalancing, pooling and striping, obstruct and page caching, tiering using persistent recollection (also known as storage class memory, SCM), write coalescing and dynamic resizing. There are many trade-offs to beget with various performance parameters and power management to enable more predictable latency.
In addition to HW/SW co-design, lore of the application domain opens new optimization opportunities and architectures. Facebooks OCP flash-based hardware is shown below.Image from OCP pinnacle Presentation
The speakers gave key value store (KVS) as an application example. Key value stores incur tall write amplification and a lot of data sharding. There are huge differences in BW: 120 MB/s reads/writes of tiny keys and values (256 bytes) vs. 3000 MB/s disk reads and writes. Keeping amplified I/O local saves networking, improves latency, especially tail latency.
Key/Value stores are CPU- and DRAM-hungry. Lightning JBOF-based designs achieve advantageous sharing, and Great capacity management. This is flawless for obstruct protocols, but difficult to elope RocksDB—1 JBOF + 5-15 RocksDB hosts works perfectly but 1 JBOF + 5-15 RocksDB instances + 5-15 DB hosts is extremely unbalanced. One neeeds to acquire a elastic combination of CPU+DRAM+SSD.
For RocksDB expend cases achieve better ratios with two NVMe SSD per server in Yosemite Chassis: 1 CPU + X DRAM +4-8 TB SSD. Compare this against JBOF based design with 2 CPU + Y DRAM + 60-240 TB SSD.
According to the presenters, HW rearchitecting goes hand-in-hand with SW reconfiguration. At scale, getting efficiency is hard. need a elastic set of structure blocks—the right ratios of CPU, DRAM and SSD within each server connected with low-cost high-speed networks. Customize architectures to be application aware.
Manoj Wadekur from Facebook and Anjaneya “Reddy” Chagam from Intel spoke about disaggregated storage architecture. The design below compares local attached storage with disaggregated storage using the compute node (to create a ratiocinative disaggregation) and at a storage head node with physical storage disaggregation. In both cases disaggregation results in more efficient utilization of storage resources.Image from OCP pinnacle Presentation
NVM Express (NVMe) is the standardized interface designed around the capabilities of non-volatile snappily recollection and storage. NVMe, based on the snappily PCIe computer bus is rapidly displacing older SSD interfaces, such as SATA and SAS. NVMe has low latency due to direct CPU connection and has no host bus adapter, resulting in lower power and lower cost. NVMe SSDs are now available in a Great many profile factors such as PCIe AIC, SFF-8639, M.2, SATA Express and BGA.
With the latest NVMe gauge release NVMe can drudgery over an Ethernet fabric as shown below. This enables sharing of NVMe twinkle storage over this network using traditional obstruct protocols (e.g. iSCSI) or NVMe optimized protocols (e.g. NVMe/TCP). NVMe over Fabrics (NVMe-oF) supports fiber channel and infiniband transport in addition to Ethernet.Image from OCP pinnacle Presentation
Disaggregating twinkle storage enabled independent scaling of compute and storage ersources for cloud workloads and using NVMe over TCP/IP enables disaggregation of twinkle storage without requiring changes to networking infrastructure.
Mellanox (which announced its coming acquisition by NVIDIA just before the OCP Summit) is playing an famous role in composable infrastructure using NVMe-oF. At the OCP pinnacle is announced its NVMe SNAP (Software-defined Network Accelerated Processing) storage virtualization solution for public cloud, private cloud and enterprise computing.
The company’s NVMe SNAP solution is said to liquidate the inefficiency of local storage while addressing a growing need for compute and storage disaggregation and composability at cloud scale. NVMe SNAP enables faster adoption of NVMe over Fabrics (NVMe-oF) in different data heart environments by enabling seamless integration into almost any server with any operating system or hypervisor, effectively enabling immediate deployment of NVMe-oF technology for any application.
The NVMe SNAP solution, delivered as participate of the BlueField family of PCIe SmartNIC adapters, makes networked twinkle storage appear as local NVMe storage, effectively virtualizing the physical storage. NVMe SNAP makes expend of texisting NVMe drivers, to give customers the composability and flexibility of networked twinkle storage combined with the advantages of local SSD performance, management, and software transparency.Image from OCP pinnacle Presentation
This NVMe SNAP technology is combined with BlueField’s multicore Arm processors and virtual switch and RDMA offload engines, to enable a broad purview of accelerated storage, software defined networking, and domain specific application solutions. The Arm processors in combination with SNAP can be used to accelerate distributed file systems, compression, de-duplication, substantial data, synthetic intelligence, load balancing, security and many other applications.
In its briefing talk, Mellanox identified many partners who are using their BlueField NVMe-oF technology including Celestica, Dell/EMC, E8 Storage, Excelero, MITAC, NetApp, unadulterated Storage and vmware.
Computational storage was another theme at the OCP Summit. Computational storage reduces the need to poke data in order to process the data in storage devices. There are several companies working on this technology. At the OCP pinnacle NGD Systems announced the general availability of its 16TB U.2 NVMe SSD, the first of its Newport Platform of products for broad deployment of computational storage devices.NGD Company Product Image
The Newport Platform offers the highest capacity NVMe SSDs and leverages In-Situ processing to liquidate the need for data movement to main recollection prior to processing. The Newport Platform makes it viable to implement smart edge and hyperscale environments with much greater efficiency and lower cost, providing customers a significant TCO benefit.
Silicon Motion Technology Corporation released its SM2271, an SSD controller ASIC with a firmware stack for high-performance enterprise SATA SSDs with a maximum capacity of 16TB. The SM2271 is a performance, eight-channel enterprise SATA SSD controller solution that supports 3D TLC and QLC twinkle technologies. It exploits the potential of the SATA interface, achieving a maximum sequential read quicken of 540MB/s and sequential write quicken of 520MB/s.
The SM2271 combines enterprise endurance, advocate for tall SSD capacity, and performance for read-intensive workloads while enabling users to maintain their existing SATA storage infrastructure for a low TCO. Providing more consistent latency than client SSDs for more liable data write and read operation, it is a platform for SATA SSD designs intended to supplant lower-performance HDDs in enterprise storage, data heart and industrial storage systems.
Erich Haratsch from Seagate spoke about using SSD with Compression in compute and storage infrastructure. He said that confusion exists about benefits, expend cases and data integriy when SSDs implement compression. Some data (such as data bases, OS files and various application data are typically highly compressible. Other data, in particular images and video files are often more difficult to compress.
He pointed out that SSD compression algorithms need to be lossless (that is, total the data can be reconstructed from the compressed content). Compression needs to elope inline at the rate of the data rush so there is low repercussion on writing and reading latencies. Compression must moreover be done before encryption and ECC coding. If used correctly, for many types of data, compression reduces the data written to the media (here twinkle memory). An SSD with compression must acquire a twinkle translation layer (FTL) that can manage physical data units of variable size.
If done properly compression can extend effectual overprovisioning. Although the ratiocinative capacity doesn’t change the write amplification is reduced and thus it increases endurance. It moreover increases random write and mixed read/write performance. Compression can moreover be used to extend the ratiocinative capacity of the SSD, the resulting extra ratiocinative capacity depends upon the stored data entropy.
Applied to quad-level cell (QLC) NAND, compression can extend the twinkle endurance, performance and/or user capacity. Seagate’s Nytro 1000 SATA SSD has the company’s DuraWrite lossless data reduction technology to extend performance and deliver hig-hpower efficiency. Erich made a convoke for action for compression-enabled SSD devices in the Open Compute Project.
Kushagra Vaid from Microsoft spoke about updates in the Cerberus security specification, introduced eventual year with the Root of trust domain extended to peripheral components such as NICs, SSDs and accelerators and said that it was implemented on total Project Olympus motherboards. They moreover gave Denali updates where this elastic SSD for cloud-scale applications could be extended to storage/media disaggregation beyond the cloud as shown below.Image from OCP pinnacle Presentation
He moreover spoke about a new open source loss-less compression, called Project Zipline targeted at legacy and modern datasets from the edge to the cloud. This initiative is said to provide always-on data processing with tall compression ratios, tall throughput and low latency. The release included Verilog RTL source and test suite, allowing rapid implementation. One of the expend cases was archival storage, but perhaps it could be implemented with storage devices as well (like the Seagate approach).
The 2019 OCP pinnacle revealed storage solutions to advocate machine learning, compression, composable storage infrastructure and the wide-spread utilization of NVMe and NVMe-oF to create the next generation of data heart storage solutions.
