Solving the new bottleneck problem

The long-awaited launch of Intel’s Nehalem processor is poised to revolutionize HPC. Its ability to drive much higher compute and data manipulation capacities eliminates the bottleneck at the server level – but does not automatically translate to scalability. Suddenly we see that the bottleneck is transitioning to the server interconnect and I/O. In order to realize the true power of Nehalem, you must have a network fabric that can keep up.

That’s where Voltaire comes in. Voltaire provides a family of QDR (40 Gb/s) InfiniBand switching products and a unique fabric optimization technology that relieves the I/O bottleneck. More than 30 percent of the Fortune 100 and many of the TOP500 supercomputers use Voltaire solutions. Our switches and software enhance Nehalem with balanced and scalable cluster performance and drive higher system efficiencies – and are Intel Cluster Ready Certified.

We’re proud to be part of the Intel Cluster Ready community and look forward to using this forum to share our expertise on how to open I/O bottlenecks and maximize the utilization of Intel-based systems. In the coming months, we’ll cover topics such as:

-    The impact of faster CPU and memory on I/O
-    The implications of I/O as the new limiting factor, and ways to address it
-    Topologies and emerging switching solutions that can reduce latency
-    Increasing utilization and scalability with fabric optimization
-    Addressing storage I/O challenges

If there are any other topics you’d like us to discuss, we are open to your ideas and questions. Contact us at info@voltaire.com. You can also view our full line of Intel Cluster Ready Certified Solutions at www.voltaire.com/ICR.

We look forward to an active conversation with the ICR community. Thanks for reading!
