RAID Disk Group
One of the most critical decisions when deploying a new storage solution is which RAID type(s) to use,
as that choice heavily impacts application performance. Dell tested nine RAID 1 disk groups for
database data files and one RAID 1 disk group for log files. This left four disks in the front of the
chassis, two in RAID 0 to be used for staging data, and the remaining two for spare drives. The back
two disks were used in a RAID 1 disk group for the operating system.
Internal Storage System
Fast Track Reference Guidelines define three primary layers of storage configuration:
• Physical disk array (RAID groups for data and logs)
• Operating system volume assignment (virtual disk)
