Hello,
We have a low-end platform of using Core2duo
(Xeon) with 4G ram.
The budget is not much enough to afford
SAN.
We consider SAS finally, but are still having
concerns about mail access speed.
This RAID could be:
1. RAID 1 (OS) + RAID 1 (mail
spool)
2. RAID 1 (OS) + RAID 5 (mail spool)
3. RAID 50, for OS and mail
4. RAID 10, for OS and mail
Option 1 is found difficult to expand its mail
spool
RAID 5 is not good for speed, but it can
expand
RAID 50 speed is much slower than RAID 10, but
RAID 10 is very expensive
Anyone here can provide suggestions?
Thanks
Patrick
