100GbE Switches – Have You Done The Math?

100GbE switches – sounds futuristic? Not really, 100GbE is here and being deployed by those who do the math… 100GbE is not just about performance, it is about saving money. For many years, the storage market has been “doing the math”, $/IOPs is a very common metric to measure storage efficiency and make buying decisions. […]

A Look At The Latest Omni-Path Claims

Once again, the temperature kicked up another few degrees in the interconnect debate with HPC Wire’s coverage based on information released by Intel on the growth of Omni-Path Architecture (OPA). According to Intel, the company behind OPA, have been seeing steady market traction. We have always expected Intel to win some systems, same as QLogic […]

OpenStack Summit Austin 2016

The OpenStack Summit is a five-day conference for developers, users, and administrators of OpenStack cloud software. Held every six months, the conference schedule rotates based on the OpenStack software release cycle.  This week, the summit is being held in Austin, Texas at the Austin Convention Center. The summit started yesterday and we had two successful […]

Content at the Speed of Your Imagination

In the past, one port of 10GbE was enough to support the bandwidth need of 4K DPX, three ports could drive 8K formats and four ports could drive 4K-Full EXR.  However, the recent evolution in the media and entertainment industry that has been presented this week at the NAB Show showcases the need for higher resolution.  […]

Road to 100Gb/sec…Innovation Required! (Part 3 of 3)

Physical Layer Innovation: Silicon Photonics 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 […]

Road to 100Gb/sec…Innovation Required! (Part 2 of 3)

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 […]

Road to 100Gb/sec…Innovation Required! (Part 1 of 3)

Transport Layer Innovation: RDMA During my undergraduate days at UC Berkeley in the 1980’s, I remember climbing through the attic of Cory Hall running 10Mbit/sec coaxial cables to professors’ offices. Man, that 10base2 coax was fast!! Here we are in 2014 right on the verge of 100Gbit/sec networks. Four orders of magnitude increase in bandwidth […]

How Scale-Out Systems Affect Amdahl’s Law

In 1967, Gene Amdahl developed a formula that calculates the overall efficiency of a computer system by analyzing how much of the processing can be parallelized and the amount of parallelization that can be applied in the specific system. At that time, deeper performance analysis had to take into consideration the efficiency of three main […]

Mellanox Technologies Delivers the World’s First 40GbE NIC for OCP Servers

Last year, Open Compute Project (OCP) launched a new network project focused on developing operating system agnostic switches to address the need for a highly efficient and cost effective open switch platform. Mellanox Technologies collaborated with Cumulus Networks and the OCP community to define unified and open drivers for the OCP switch hardware platforms. As a […]
