RAID Setup Procedure

Each SBI-7226T-T2 blade module supports four hard drives, two per node, which may be used to create a RAID array. For the blade’s B8DTT mainboard, you may use the BIOS setup to configure for either the Intel or Adaptec RAID controller and utility: use the Intel driver for Windows and the Adaptec driver for Linux - both are included on the CD that ships with the system.

Important Notes

Please read the following notes and warnings before setting up your RAID array.

NOTE: Before adding a new drive to an array, back up any data contained on the new drive. Otherwise, all data will be lost.

NOTE: If you stop the BUILD or CLEAR process on a RAID 1 from the ACU, you can restart it by pressing <CTRL> + <R>.

NOTE: A RAID 1 created using the QUICK INIT option may return some data miscompares if you later run a consistency check. This is normal and is not a cause for concern.

NOTE: The ACU allows you to use drives of different sizes in an array. However, during a build operation, only the smaller drive can be selected as the source or first drive.

NOTE: When migrating from single volume to RAID 0, migrating from a larger drive to a smaller drive is allowed. However, the destination drive must be at least half the capacity of the source drive.

WARNING: Adaptec does not recommend that you migrate or build an array on Windows dynamic disks (volumes), as it will result in data loss.

WARNING: Do not interrupt the creation of a RAID 0 using the MIGRATE option. If you do, you will not be able to restart or to recover the data that was on the source drive.
