HP smart array p212 raid controller. Only two arrays possible? because of missing RAM on raid card?
Does the PERC6i card support multiple RAID arrays?RAID Array performance on an HP Proliant ML350 G5 Smart Array E200iHow can I force HP Smart Array RAID controller to re-recognize drives?Is it possible to recreate a raid 1+0 array without losing datamoving raid 10 to another identical server both on Smart Array 6i controllersHP Smart Array P212 hangs after firmware updateHP Smart Array P212 - rebuild Array 1 for OS without loosing Array 2 (Data)How to make individual disk as logical/physical disks from HP smart arrayReplace HDD in “predictive failure” state with spare HDD in HP Smart Array P400 controllerP212 Smart array not configured
I bought a HP Proliant gen8 microserver. In it I installed 1 * 500GB SSD connected to SATA port 5 as a bootable disk and 4 * 3TB HDD connected to a HP smart array p212.
What I would like to do is create 1 array using HDD 1 and 2 as a RAID 1 configuration. The other hard drives will contain data that does not need mirroring and may be in a RAID 0 configuration, one array for HDD 3 and one array for HDD 4. This would become array A (RAID HDD 1 and 2), array b (RAID 0, HDD 3) and array c (RAID 0, HDD 4). I was able to do this on the soft RAID functionality. But using that also introduced other issues.
My issue is that I do not get the posibility for creating array c. It will let me create array a and array b. And it will show me that HDD 4 is a unassigned disk. In the image below you can see that the 'create array' button is gone.
Current array config
I am able to create array A and array B both in RAID 1 and use all 4 HDD's. So connecting to all drives is not an issue.
Could the fact that I am not using any cache memory on the p212 card be the issue? From what I understand this would mainly upgrade your throughput of read and write data.
If I do need this RAM module, do I realy need a backup battery to get it operational like the seller for the card is telling me? From what I understand the battery is only needed in case of a power outage and it is not mandatory.
From a risk perspective I am willing to take the risk of power outage because I would not mind if some data gets scrambled since this system would be a backup for photo's on mobile devices. The other data on the RAID 0 disks are more of a 'nice to have' nature, so data loss on those disks wouldn't matter anyway.
Thanks in advance.
