2. Server Configuration

Each system ran the same custom Linux 2.6.20 kernel, with patches for FAST TCP and other TCP performance tunings built in.

Based on the different hardware combination, systems were grouped into four main categories:

A) 1U Servers with Fiber Channel Storage System + Intel Oplin 10 GbE NIC

8 of  the 1U systems were outfitted with Intel Oplin single port 10GbE NIC and a QLogic  fiberchannel HBAs connected to Data Direct Networks storage system. Maximum read/write speeds between 350-400MB/s.

B) 1U Servers with Local Storage + Intel Oplin 10 GbE NIC

4 of the 1U systems were outfitted with Intel Oplin single port 10GbE NIC and local storage with RAID-0 was used to source/sink data.
Maximum read/write speeds at 200MB/s.

C) 1U Servers with Local Storage + Myricom 10 GbE NIC

20 of 1the U systems were configured with Myricom 10GbE NIC while the 4 hard drives were placed in RAID-0 configuration. Maximum read/write speeds at 200MB/s.

D) 2U Servers with Local Storage + Myricom 10 GbE NIC

The 4 x 2U servers were whitebox systems with Myricom 10GbE NIC and each system having 12 hard disks connected through Areca 1231ML RAID Controller and placed in RAID-0. Maximum read/write speeds at 500MB/s.
