DL160 G6 (490454-421) 2-4 disk backplane

[Mark R. P. Thomas]

Hi,

I have a 1U Proliant server (model in subject) with two hot-plug 3.5" SATA disks in RAID-1 on a 2-disk backplane using the factory Smart Array P410 RAID controller. I would like to add two more hot-plug disks for a second RAID-1 pair but I need, at very least, to replace the backplane with a 4-drive model first.

1. Is the HP 4 Hard Drive Hot Plug Backplane G6 Kit (512181-B21) suitable?
2. Is the backplane the only modification required?
3. Is the RAID controller able to run the 2 additional disks or are there likely to be licensing issues restricting me to 2 disks?

Many thanks in advance,
Mark

P410 can do RAID 10 and 50. So it can handle more drives. You might need a battery cache to expand the array.

512181-B21 should work on that server. Backup before moving drives to it.

Thanks for your quick reply. The existing drives are 160GB each that ideally will be used for the OS. I would like to add two 500GB drives for data.

Being that the drives are of dissimilar size, I would expect to create two RAID-1 volumes that are independent of one another rather than one RAID-10 volume. Is this the correct approach?

Regards,

Yes, on servers I do

OS: RAID 1
Apps/Data: RAID 1 or 10
Paging: RAID 1

Great - this is useful to know. Thanks.

backup and verify it before moving drives.
