Table13: Archival File Server RAID Guidelines
Application
File -
Archival
Recommended:
RAID 10 – Recommended due to high availability, redundancy, and good performance.
•
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.
Possible:
RAID 1 – Possible solution in situations which do not require high storage capacity.
•
Not recommended:
RAID 0, Concatenated - These are not recommended due to lack of redundancy and data
•
protection. Even for long term archival storage which is intended to be a backup of
important files, it is not a recommended solution.
Note: While these configurations are not recommended, they can be configured and utilized.
