The Dell PowerEdge Expandable RAID Controller Card Configuration Utility (BIOS) is accessed by hitting CTRL-R (or CTRL-C) at System Startup. From here, you can setup new RAID Arrays and maintain existing ones.
There are normally three options within the Configuration Utility:
- Virtual Disk Management (these are the “Disks” that the Operating System can “see”)
- Physical Disk Management (these are the physical disks attached to the Controller Card)
- Controller Management
If you have an existing RAID Configuration, you may wish to think carefully before selecting any of the following options:
- “Easy Configuration” will WIPE the existing Configuration / Disks
- “New Configuration” will WIPE the existing Configuration / Disks
- “Initialise” will WIPE the existing Configuration / Disks
- “Clear” will WIPE the existing Configuration / Disks
Dell has various RAID Controller Cards available. Below is a summary of the more common ones:
This is an “entry level” card that only supports RAID 0; RAID 1 and RAID 10. Also, the number of Virtual Disks is limited to two. So, an ideal configuration would be a RAID 1 array for the Operating System and a second RAID 1 array to house the Data.
This card supports RAID 0,1,5,6,10.
