Our cluster’s computers are a mix of HP and Dell sys-tems with a range of RAM (24GB to 96GB) and CPUs (2 to 12 cores). The compute nodes had a single local
disk, used only for operating system files. Storage nodes had one operating system disk plus between 5 and 16 FDS data disks used for sort data. These disks had a
range of capabilities: primarily (78%) 10K RPM dual-port SAS disks, but with some 22%) 7,200 RPM SATA disks. Each computer is networked using 10G (10 giga-bit/sec) Ethernet connected in a full-bisection-bandwidth CLOS network [5]. The interconnect is 22×Blade G8264 switches, each of which has 64×10G Ethernet ports. Most computers had a dual-port 10G NIC (an In-tel X520 or HP NC522SFP), though some of the storage nodes used only a single port. All computers run Win-dows Server 2008 R2 SP1.
