Back To Basics: What Is Virtualization?

You’ve heard the term “virtualization.” You’ve heard that it can save you money, improve performance and let seemingly incompatible systems work together. But for many companies, the transition from theoretical benefits to in-house application isn’t always so simple. Part of the problem is confusion — what exactly is virtualization, and how does it work? Let’s get back to basics.  WhatRead More

InfiniBand: The Competitive Advantage (Server Talk Episode 6)

In this intro to the InfiniBand technology, we take a high-level overview of the key benefits of using IB in HPC and supercomputing environments

SAS, SATA, and iSCSI – A Tutorial

Yesterday there was a great piece over at TechRepublic on the confusing intersection of SAS, SATA and iSCSI arrays. For anyone who has ever had a difficult time understanding and differentiating these technologies, this is a very valuable resource. Excerpts are cross-posted below. SATA and SAS are storage interface and bus types designed to aid in the movement of data fromRead More

Intel MIC and its Comprehensive Networking Strategy

Last week we talked about the upcoming release of Intel’s Xeon E5 processor family. This week, we have some even more important announcements regarding Intel MIC and the strategic direction that Intel is headed regarding high performance computing.

How a SAS switch can improve storage management

Last week, LSI announced their release of “the industry’s first 6Gb/s SAS switch”. The switch offers unique opportunities for cluster managers to improve the architecture of their storage systems. The value of the SAS switch is its function of transforming a cluster from a NAS (network-attached storage) structure into a DAS (direct-attached storage) structure. With DAS, storage data does notRead More

Software Driven Networking: Enabling New Internet Speed Protocols

A team from the Korea Advanced Institute of Science and Technology created a router, built from parts found in most high-end desktop computers, that transmits data at nearly 40 GBps. The technique used by the scientists could lead to the development of cheap commodity chips, replacing the custom made hardware in high performance routers. The software could lead to theRead More

Great introduction to Infiniband

The InfiniBand Trade Association published a very useful white paper that is an introduction to InfiniBand technology. InfiniBand is a network technology that greatly boosts computing performance by allowing applications in different parts of a standard network to communicate without the standard network’s usual communication channels. By using only the server resources those applications need and little else, InfiniBand canRead More
