Hi Everyone

The machine is IBM x345 with ServeRAID 6i 128mb cache and 6 SCSI 15k
disks.

2 disks are in RAID1 and hold the OS, SWAP & pg_xlog
4 disks are in RAID10 and hold the Cluster itself.

the DB will have two major tables 1 with 10 million rows and one with
100 million rows.
All the activities against this tables will be SELECT.

Currently the strip size is 8k. I read in many place this is a poor
setting.

Am i right ?
