Exchange storage design question |
|
|
Hi all,
We will have to replace our Exchange 2000 hardware. We got an interesting
offer from DELL: 4 x 72 Gb disks. We have an Exchange database of 10 Gb and
300 users. I don't know which RAID level to choose:
1) 2x RAID 1 (system & logs, database)
2) RAID 5 : One volume (with raided 3 disks) separated into 3 partitions
(system, logs, database) + 1 spare disk
3) RAID 0+1 : 3 partitions (system, logs, database)
Any comment or suggestion would be appreciated.

It is considered best practice to separate out the OS, Logs and DBs on
separate physical drives. Depending on the amount of users you have, you
could take option 1 which will at least separate your logs and DBs.
Separating out by partitioning your drive gives you nothing.
If you start to experience performance issues (high write/read latencies,
log file stalls) go and get yourself another set of disks and move the log
files off of the OS drive.
