Benchmarks for R510 Greenplum Nodes

Posted by skahler on

gpcheckperf results from hammering against a couple of our R510s. The servers are setup with 12 3.5 600GB 15k SAS6 disks split into four virtual disks. The first 6 are one group and 50GB is split off for an OS partition and the rest dropped into a data partition. The second set of six disks are setup in a similar fashion with 50GB going to a swap partition and the rest going to another big data partition. No Read Ahead, Force Write Back and a Stripe Elements Size of 128KB. Partitions formatted with XFS and running on RHEL5.6.
