I in the same situation. We purchased 2 SSD 910 PCI cards and wanted to use them in a single SQL server. The thought was to RAID them together as to eliminate a single PCI card failure. OS is Windows 2003R2 64bit. Have drivers installed and now see 8 x 186GB disks. I cannot find a way to mirror 4x186 drives from one card to the other 4x186GB drives. I can configure a RAID 5 on each of the cards (4x186) but I'll loose 1/4 of my space on each drive. So is my only option here to use "spanning" and just span each of the 4 sets of drives or even all 8 sets? Is there no way to guard against PCI card failure here? Was going to use this as the Transaction log and TempDB drive. Thank you.
