We just got a Dell with 12 x 600G 15K hot swappable disks + 2
internal 146G 15K disks (64G ram)
We will be using postgres 8.4.3 on RHEL 5 64 bit
Does it make sense to use a single Raid 10 stripe across the disks or
split into 2 sets of 3 disk pairs (given that we have 2 channels) ? We
plan to put all the postgres data on a single partition and the wal /
OS on the internal disks.
This is for a data warehouse app . The machine will receive about 200
million inserts per day.
Thanks
Sriram
