I am looking for some advice on the best possible installation method on a Dell PowerEdge server with a Perc RAID Controller. The server is a PowerEdge R510 with 8 2TB drives. As best I can tell there is no way to pass through the drive directly to the RockStor OS. I can only create a RAID 0 for each drive and then install Rockstor and each drive shows up separately, but of course I have no SMART information. I know this is not an ideal situation, but it is what I have right now. I am using this server to store backups of my production data, so it is not mission critical unless of course the production server goes down.
I have and tested Rockstor installed several different ways on this server. I have created a RAID 0 with 1 drive for the OS and then created a RAID 5 with the rest of the drives on the PERC Card and all worked fine, but from all I have read here I should not install Rockstor in a hardware raid situation. I have also created a Raid 0 for each drive then created a pool in Rockstor using Raid 1 for all the drives.
Knowing this is the only server I have available, I am looking for some guidance on the best possible installation for Rockstor in this case. Should I go with the Hardware Raid 5 or the Raid 1 from within Rockstor. The speed does suffer using the software Raid 1. I can backup about 80Mb/sec with the hardware Raid and only 60 Mb/sec with the Raid 1 in Rockstor.
Thanks in advance for the advice.
Chris
