Distributed RAID

V7.6 and later supports Distributed RAID 5 & 6 – Distributed RAID 10 is a 2016 roadmap item

Up to 10 arrays/MDisks in an I/O Group and a maximum of 32 arrays in a system

Array/MDisk can only contain drives from the same or a superior drive class

• E.g. 400GB SSDs available to build array, so only superior drives are SSDs > 400GB
• E.g. 450GB 10K SAS available to build array, so only superior drives are 10/15K/SSDs >450GB
• Recommendation is to use same drive class for array/MDisk

Traditional RAID is still supported

• New arrays/MDisks will inherit properties of existing pool you are trying to add it to
• New array width default for RAID5 is 8+P (If existing MDisks in pool are RAID5 7+P and/or 6+P then GUI will propose 6+P to match lowest width in pool)

Conversion from traditional to distributed RAID is not supported

Ability to expand an array/MDisk is a 2016 roadmap item
