Vault Report: First STAC-N of Supermicro overclocked servers and RoCE

Audited STAC-N Benchmark of Supermicro overclocked servers using RHEL 6.3 HPN Add-On and Red Hat Developer Toolset with Mellanox ConnectX-3 adapters and RoCE.

16 April 2013 - New York

As part of a testing program requested by the STAC Network I/O SIG, STAC has performed the first of several STAC-N tests of overclocked Supermicro servers using Mellanox host adapters. This report, available in the STAC Vault, documents the baseline performance of the system using RDMA over Ethernet (RoCE) with Red Hat's High Performance Network Add-On to RHEL 6.3.

"Baseline" means these results are what we obtained by applying standard tuning practices (configuring OS services, binding things to specific cores, etc.) before the product vendors were allowed to tune the system. The vendors are currently tuning, and we expect to release a subsequent report on this configuration once that is complete. Additional configurations will follow. Members of the SIG can view (and provide input to) the wish list of configurations here.

Details of this report are as follows:
