Table 21: User Store File Server RAID Guidelines
Application
File – User file
store
Recommended:
•
RAID 5 – Recommended for file servers that require maximum storage capacity and
moderate data protection and performance.
•
RAID 50 – Recommended for those solutions that require a balance between storage
capacity and performance.
•
RAID 6 – Recommended for file servers that require maximum storage capacity,
enhanced data protection, and moderate performance.
•
RAID 60 – Recommended for those solutions that require a balance between storage
capacity and performance with maximum data protection.
Possible:
•
RAID 1 – Possible solution for situations that do not require high storage capacity.
•
RAID 10 – Possible solution for situations that require greater availability and
redundancy but not as much disk capacity.
•
RAID 0 – While this solution is not redundant, RAID 0 may be useful for file servers that
require better performance and maximum storage capacity; for example, where
backups are expected to maintain data in the event of a failure.
•
Concatenated – This solution could be used for situations that require maximum
scalability as physical disks could be added as storage needs grow. For file servers that
can afford some downtime and rely on backups to restore data, this could be a solution.

priority.
•

efficiency are high priority.
