Original equipment manufacturers (OEM’s) have long dominated the optical components market but a new study now suggests that, as a result of tighter margins and greater competition, customers are putting quality and price before brand. Is the era of the big OEM at an end?
When asked their views of the optical transceiver market at the European Conference on Optical Communications (ECOC) in Cannes, over 120 attendees revealed a trend which indicates a paradigm shift in attitudes.
Why do they buy? What they buy? What keeps them up at night? The answers may surprise you:
98% of respondents ranked quality as one of their top three priorities when purchasing fibre optics
89% of respondents placed price in the top three list of priorities
Yet only 14% of respondents even considered brand names to be a top three priority – or even a concern

This week at the IBM Enterprise2014 Executive Summit in Las Vegas, IBM unveiled new Power8 based infrastructure for cloud, data, web 2.0, and mobile engagement. Mellanox is being showcased as a key partner enabling critical platforms for IBM’s Big Data analytics, cloud, and software defined “Elastic Storage” solutions. The new Power8 platform incorporates Mellanox 40Gb Ethernet networking gear and a fully integrated Turbo LAMP (Linux, Apache, MySQL, PHP) software stack.
This Turbo LAMP stack came about through a development partnership between IBM, Mellanox and several software vendors:
Canonical (Ubuntu Linux & Apache Web Server)
SkySQL (MariaDB/MySQL Database)
The Turbo LAMP integration is important as it is the foundation for the most common ecommerce, content management systems, and Big Data analytics platforms. This integration allows customers to deliver optimized mobile and web applications while offering critical performance, scale and secure access that businesses need.
On Thursday October 9, our very own Matthew Sheard will be on stage at IBM Enterprise Conference providing details on the solution as outlined in this presentation.
After the overwhelming success of Hackathon 2014 this past January, Mellanox Israel now presents 3D Hackathon: Develop, Debug, Deploy. This contest is designed to encourage innovation and teamwork, while introducing new 3D software technologies and features in a very quick turnaround time.
Mellanox Israel employees were invited to submit proposals for new software projects related to existing Mellanox technologies and to form a team of up to 3 people to develop a proposal. More than 20 unique software proposals were submitted. The steering committee evaluated and selected 16 proposals for consideration into the final competition. The top 3 teams were awarded prizes. All teams were asked to present working demos.
InfiniBand is a network communications protocol that offers a switch-based fabric of point-to-point bi-directional serial links between processor nodes, as well as between processor nodes and input/output nodes, such as disks or storage. Every link has exactly one device connected to each end of the link, such that the characteristics controlling the transmission (sending and receiving) at each end are well defined and controlled.
InfiniBand creates a private, protected channel directly between the nodes via switches, and facilitates data and message movement without CPU involvement with Remote Direct Memory Access (RDMA) and Send/Receive offloads that are managed and performed by InfiniBand adapters. The adapters are connected on one end to the CPU over a PCI Express interface and to the InfiniBand subnet through InfiniBand network ports on the other. This provides distinct advantages over other network communications protocols, including higher bandwidth, lower latency, and enhanced scalability.
Dell announced the next generation of PowerEdge servers along with a future vision that includes continued focus on application performance along with new Near Field Communications (NFC) systems management monitoring for servers along with continued support for software-defined storage. We are pleased to see this new Dell PowerEdge server line and the inclusion of our 10/40GbE NICs.
As big data analytics become more in demand by enterprise, organizations need to be able to sort and analyze vast amounts of data to guide business decisions. Large companies using ERP solutions require intensive I/O bandwidth to process multiple transactions. Using the latest processors, enhanced in-server Flash storage and Mellanox 10Gb Ethernet NICs to process more in less time, the Dell family of PowerEdge servers will enable a more seamless ERP experience.
Last but not least, the new in-server storage technology allows customers to accelerate the most important data by offering high performance with NVMe Express Flash storage and deployment of Dell Fluid Cache for SAN. This technology is also ideal for high IOPS requirements in VDI environments with thousands of high performance users, while optimizing your cost per virtual desktop. – Nicolas Cuendent, Dell, September 8, 2014
Available now from Dell, Mellanox’s ConnectX-3 Pro (PEC620) and ConnectX-3 10/40GbE NICs with RDMA over Converged Ethernet (RoCE) and overlay network offloads offer optimized application latency and performance while maintaining extremely low system power consumption.
So in two previous posts, I discussed the innovations required at the transport, network, and link layer of the communications protocol stack to take advantage of 100Gb/s networks . Let’s now talk about the physical layer. A 100Gb/sec signaling rate implies a 10ps symbol period.
Frankly, this is just not possible on a commercial basis with current technology. Neither is it possible on copper nor on optical interfaces. At this rate the electrical and optical pules just can’t travel any useful distance without smearing into each other and getting corrupted.
So there are two possible solutions. The first is to use 4 parallel connections each running @25Gb/sec. The second is to use a single channel with a 25Gb/sec symbol rate but to send four bits per symbol. This can be done either through techniques like Pulse Amplitude Modulation (PAM4) or optically by sending four different colors of light on a single fiber using Wavelength Division Multiplexing (WDM) techniques.

Mellanox congratulates Yarden Gerbi as she won the Silver medal in the recent World Judo Championship competition. The competition was held August 23-30, 2014 in Chelyabinsk, Russia. Gerbi competes in the under 63 kg (139 lbs.) division.
It was a busy time last week in San Francisco! During VMworld 2014, we announced a collaboration with VMware and Micron to enable highly efficient deployments of Virtual Desktop Infrastructure. The VDI deployment will be a combination of Mellanox’s 10GbE interconnect, VMware’s Virtual SAN (VSAN) and Micron’s SSDs. The joint solution creates a scalable infrastructure while minimizing the cost per virtual desktop user. The new solution will consist of three servers running VMware vSphere and Virtual SAN each with one Mellanox ConnectX-3 10GbE NIC, two Micron 1.4TB P420m PCIe SSDs and six HDDs.
Network and Link Layer Innovation: Lossless Networks
In a previous post, I discussed that innovations are required to take advantage of 100Gb/s at every layer of the communications protocol stack networks – starting off with the need for RDMA at the transport layer. So now let’s look at the requirements at the next two layers of the protocol stack. It turns out that RDMA transport requires innovation at the Network and Link layers in order to provide a lossless infrastructure.
‘Lossless’ in this context does not mean that the network can never lose a packet, as some level of noise and data corruption is unavoidable. Rather by ‘lossless’ we mean a network that is designed such that it avoids intentional, systematic packet loss as a means of signaling congestion. That is packet loss is the exception rather than the rule.
Lossless networks can be achieved by using priority flow control at the link layer which allows packets to be forwarded only if there is buffer space available in the receiving device. In this way buffer overflow and packet loss is avoided and the network becomes lossless.
In the Ethernet world, this is standardized as 802.1 QBB Priority Flow Control (PFC) and is equivalent to putting stop lights at each intersection. A packet on a given priority class can only be forwarded when the light is green.
