Storage Spaces Direct: If Not RDMA, Then What? If Not Mellanox, Then Who?

Over the past couple years, we have witnessed significant architectural changes affecting modern data center storage systems. These changes have had a dramatic effect, as they have practically replaced traditional Storage Area Network (SAN), which has been the dominant solution for over a decade.   When analyzing the market trends that led to this change, […]

Double Your Storage System Efficiency

Enable Higher IOPS while Maximizing CPU Utilization As virtualization is now a standard technology in the modern data center, IT managers are  now seeking ways to increase efficiency by adopting new architectures and technologies that enable faster data processing and execute more jobs over the same infrastructure, thereby lowering the cost per job. Since CPUs […]

How-old.net and the Driving Forces behind the Age of Machine Learning

I am on a business trip and had dinner with a few coworkers last night. During dinner, one of them proudly pulled out his smartphone and bragged about how young how-old.net thinks he is. Indeed, the age that how-old.net spat out was about 2/3 of his real age.   Of course, he had to take […]

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 […]

Establishing a High Performance Cloud with Mellanox CloudX

When it comes to advanced scientific and computational research in Australia, the leading organization is the National Computational Infrastructure (NCI).  NCI was tasked to form a national research cloud, as part of a government effort to connect eight geographically distinct Australian universities and research institutions into a single national cloud system.   NCI decided to […]

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 RDMA Increases Virtualization Performance Without Compromising Efficiency

Virtualization has already proven itself to be the best way to improve data center efficiency and to simplify management tasks. However, getting those benefits requires using the various services that the Hypervisor provides.  This introduces delay and results in longer execution time, compared to running over a non-virtualized data center (native infrastructure). This drawback hasn’t […]

RoCE in the Data Center

Today’s data centers demand that the underlying interconnect provide the utmost bandwidth and extremely low latency. While high bandwidth is important, it is not worth much without low latency. Moving large amounts of data through a network can be achieved with TCP/IP, but only RDMA can produce the low latency that avoids costly transmission delays. […]

Building an Enterprise Class Big Data Solution with IBM BigInsights, IBM GPFS, FPO and Mellanox RDMA

Big Data solutions such as Hadoop and NoSQL applications are no longer a sole game for Internet moguls. Today’s retail, transportation and entertainment corporations use Big Data practices such as Hadoop for data storage and data analytics. IBM BigInsights makes Big Data deployments an easier task for the system architect. BigInsights with IBM’s GPFS-FPO file […]

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 […]
