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 10 disk group for log files. This left two disks in the front of the
chassis for spare drives, while 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)
• Databases (User, System Temp, Log)
