NVMe Over Fabrics Standard is Released

Today, the NVM Express Organization released version 1.0 of the NVM Express over Fabrics (NVMf) Standard. This effort was started on September 3rd, 2014 and through the efforts of many companies including Mellanox, has now been completed. Although the Standard was only completed today, at Mellanox, we have been doing proof of concepts and demonstrations […]

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 […]

Becoming Familiar with the Mellanox “Smart Interconnect”

Mellanox is renowned for furthering development toward a more effective and efficient interconnect, and today we’re weaving intelligence into the interconnect fabric, improving our acceleration engines, and adding  improved capabilities that further remove communication tasks from the CPU and dramatically increase system efficiency. Historically, increases in performance have been achieved around a CPU-centric mindset, with […]

One Step Closer to Exascale Computing: Switch-IB 2 & SHARP Technology

A typical metric used to evaluate network performance is its latency for point-to-point communications.  But more important, and sometimes overlooked, is the latency for collective communications, such as barrier synchronization used to synchronize a set of processes, and all-reduce, used to perform distributed reductions.  For many High-Performance-Computing applications, the performance of such collective operations play […]

How to Achieve Higher Efficiency in Software Defined Networks (SDN) Deployments

During the last couple of years, the networking industry has invested a lot of effort into developing Software Defined Network (SDN) technology, which is drastically changing data center architecture and enabling large-scale clouds without significantly escalating the TCO (Total Cost of Ownership).   The secret of SDN is not that it enables control of data […]

Introduction to InfiniBand

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 […]

Deploying Hadoop on Top of Ceph, Using FDR InfiniBand Network

We recently posted a whitepaper on “Deploying Ceph with High Performance Networks” using Ceph as a block storage device.  In this post, we review the advantages of using CephFS as an alternative for HDFS. Hadoop has become a leading programming framework in the big data space. Organizations are replacing several traditional architectures with Hadoop and use […]

Mellanox Powers EMC Scale-Out Storage

This week is EMC World, a huge event with tens of thousands of customers, partners, resellers and EMC employees talking about cloud, storage, and virtualization. EMC sells many storage solutions but most of the excitement and recent growth (per the latest EMC earnings announcement) are about scale-out storage, including EMC’s Isilon, XtremIO, and ScaleIO solutions. […]

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 […]

Four Big Changes in the World of Storage

People often ask me why Mellanox is interested in storage, since we make high-speed InfiniBand and Ethernet infrastructure, but don’t sell disks or file systems.  It is important to understand the four biggest changes going on in storage today:  Flash, Scale-Out, Appliances, and Cloud/Big Data. Each of these really deserves its own blog but it’s […]
