I'm looking for a recommendation on block size and RAID0 stripe size.
We have a RAID0 array consisting of six SAS drives. The array is a workspace for SAS programs (I know, the various SAS references are confusing). We have a handful of these workspaces set up, and so when a user submits a SAS program on our server, their program gets it's own dedicated workspace.
Our current set up:
OS: SLES 11
Filesystem block size: 4k
RAID0 stripe size: 64k
There are also application level settings for SAS for block size (BLKSIZE), currently set to 256 bytes -- this must have been a default value.
Is anyone familar with setting up workspaces for SAS processing that could provide feedback on our current settings? We are looking to increase performance and speed up program run times. Let me know if I've left out any information.
