Question

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?

Options

  • AStriped with 100 GB on RAID group 1, RAID group 2 and RAID group 3.
  • BConcatenated with 50 GB on RAID group 1 and 250 GB on RAID group 3.
  • CStriped with 150 GB on RAID group 1 and RAID group 2.
  • DConcatenated with 100 GB on RAID group 1, RAID group 2 and RAID group 3.
