Thanks, I have an additional question for you regarding adding drives to the existing RAID array (RAID 5).
We would like to add 6 more drives to each of our storage modules so each is fully populated (12 disks, we have 4GB of RAM in each SSM so the prereq is not an issue.). The way I read the manual seems to indicate that we should be able to install the new drives, turn them on and add them to the array without having to reconfigure the RAID set and lose the data that exists on drives in the current array.
Is that correct or am I reading it wrong? Does this actually take us from RAID 5 to RAID 50
Thanks for your help.
-----------From p86 of the manual-----------
Before you add disks to the SSM, be sure that the SSM has enough memory to use the
additional disks. See “Memory Requirements for Adding Disks” on page 85.
Warning: Adding a disk to RAID deletes any existing data on that disk.
1. Add the new disks to the SSM.
You must add disks in contiguous disk bays, from left to right and, for the Intel®
Storage System SSR212MA, from top to bottom, as shown in Figure 68 and
2. Using the Console, log in to the SSM.
3. Select the Storage configuration category.
4. Click the Disk Setup tab to bring it to the front.
The new disks will show a red X and be listed as Off.
5. Select the new disks and click Power On Disk.
The disk status of the new disks becomes Uninitialized.
6. Select the new disks and click Add Disk to RAID.
Shift-click to select multiple disks to add to RAID
• pairs of disks to RAID 1/10 or
• sets of 4 or 8 disks to RAID 5/50 [Intel® Storage System SSR316MJ2] or
• sets of 6 disks [Intel® Storage System SSR212MA].
RAID begins to rebuild on the new disks according to the RAID Rebuild rate
configured on the RAID Setup tab.
As soon as the RAID Status shows Normal, the disks provide fully operational data
redundancy with the mirror in place. The SSM is ready for data transfer at this point.
The newly added disks display on the RAID Setup tab.
Yes you're correct. See page 66 of the manual:RAID 5 and RAID 50 can only be configured on completely populated sets of disks. Thismeans the Intel® Storage System SSR212MA must contain either 6 or 12 disks.Whether the Intel® Storage System SSR212MA is configured in RAID 5 or RAID 50depends on the number of disk sets in the module.• If the Intel® Storage System SSR212MA contains 1 disk set, then that set is RAID 5.• If the Intel® Storage System SSR212MA contains 2 disk sets, then both sets areRAID 50.
