Picking a solution based on the application profile
One of the most important factors to consider when selecting a storage solution is the type of
application that will be utilizing the storage solution. This defines the overall purpose of the
server/storage solution and will determine what RAID configuration will be optimal for the
application. Table 5 outlines the recommended RAID solution based on the usage of the server.

General RAID Configuration Guidelines
RAID 0
RAID 0 is generally not a recommended solution due to lack of data redundancy and protection.
However, it may be utilized in situations where this is not required and maximum storage capacity
and performance are essential.
RAID 1
A RAID 1 solution, while not ideal, could be utilized for small workgroup servers or servers with low
storage capacity and growth requirements. Any server beyond a small workgroup server is likely to
need more storage and consequently, a more efficient RAID solution.
