Keeping in mind the best practices, how would you create a metaLUN?
A customer needs to give a host 300 GB of disk space to improve performance. The VNX to be used has three RAID groups available.
– RAID group 1 is RAID 5 (4+1) with 240 GB free
– RAID group 2 is RAID 5 (4+1) with 220 GB free
– RAID group 3 is RAID 5 (6+1) with 250 GB free
The utilization of each RAID group is minimal and all use 300 GB SAS drives. Keeping in mind the best practices, how would you create a metaLUN?
