Server Q&A

Gigabyte has been making an aggressive push into the server market, and this week, just in time for GTC in San Jose California is releasing the Gigabyte GS-R22PHL. The GS-R22PHL is a dual Intel Xeon E5-2600 2U server that can support up to eight 2.5″ drives and 512GB of RAM. While this would likely be considered a fast supercomputing platform a few years ago, in today’s market GPU solutions such as the NVIDIA Tesla series or the Intel Xeon Phi series are very important to accelerate certain parts of code that can be highly parallel and small enough to fit in limited memory of accelerator cards. The Gigabyte GS-R22PHL keeps the centerline of the chassis focused on a standard dual LGA2011 Intel Xeon E5-2600 server while the sides of the rackmount chassis are completely reserved for GPUs/ Intel Xeon Phi cards and supporting fans for proper airflow. e3-1575m v5


The Gigabyte GS-R22PHL is designed to consume a lot of power. With eight 200+ watt GPU or Intel Xeon Phi cards installed in a chassis plus two Intel Xeon E5-2600 series CPUs with 10GbE connectivity, these chassis are sure to take a lot of power. Gigabyte offers redundant 1600w power supplies that are 80 PLUS platinum-certified. These power supplies may seem extreme but are needed in the Gigabyte GS-R22PHL.

The main purpose of the chassis is to support up to eight dual slot GPU based accelerators such as the NVIDIA Tesla series or Intel MIC co-processors. One can see from the above picture four accelerator card cages two on each side of the chassis. There is direct airflow to the PCIe cards and mid-chassis fans to move air through at a very fast rate. Here is Gigabyte’s photo with two Intel Xeon CPU Phi cards in an expansion cage.

Quick specs for the Gigabyte GS-R22PHL supercomputing platform can be found in the following togglebox:

It is always good to see additional competition in the server market. Gigabyte has been venturing to do some things slightly different with their machines such as using Avocent based IPMI 2.0 instead of a standard AMI MegaRAC offering.
