It’s very common for a server running Windows Unified Data Storage Server and the Microsoft iSCSI Software Target to include a RAID controller and many hard drives in the box. I got a question on exactly how to configure RAID volumes for this kind of setup. The standard “it depends” engineering answer does apply here. However, allow me to elaborate on that :-).

First of all, it helps to understand a few details about the hardware. The main thing here is the types of RAID supported by the controller (RAID 0, 1, 5 and 10 are common, RAID 6 is sometimes available). It’s also important to know how many physical disks you have there, since this will impact you options (RAID 1 requires 2 disks, RAID 5 requires at least 3 disks).
