Hi,
One simple question. For 125 or more checkpoint segments (checkpoint_timeout is 600 seconds, shared_buffers are at 21760 or 170MB) on a very busy database, what is more suitable, a separate 6 disk RAID5 volume, or a RAID10 volume? Databases will be on separate spindles. Disks are 36GB 15KRPM, 2Gb Fiber Channel. Performance is paramount, but I don’t want to use RAID0.
PG7.4.7 on RHAS 4.0
I can provide more info if needed.
Appreciate some recommendations!
Thanks,
Anjan
