RAID recommendation

[Brian F]

Hello,

I will be deploying a replacement server for a Java webapp server w/SQL.
Current system:
ProLiant DL580G2, quad 1.4 Xeons, 8GB mem, (4) 72GB RAID5

New system:
ProLiant DL385G2, dual dual-core Opterons, 8GB mem, (6) 146GB SAS

Looking for advice on RAID setup.
RAID5, RAID1+0, mix of RAIDs ?
redundancy and performance are equally important ... well,maybe lean a bit more to perf.
Thanks!

Hi,

... so, I suggest to you to choose RAID 5.

if, also, you choose to utilize the Hot Spare drive you'll have 4x146 GB of total capacity.

Bye.

Hi...

I will suggest you go for Raid5 with one hot spare HDD. Its a good environment for performance as well as for redudancy.

Thnx

Brian:


To maximixe the available space and redundancy, I would suggest you create 1 Array with 5 disks and add the 6th drive as a spare.

You will still be able to create multiple Logical Drives with different RAID settings. I suggest 12 to 30GB RAID1 for your OS (if you need that much), some space for logs RAID1 and some space for data RAID5.
