What is the best way to set up a FAST VP pool on a VNX Block system running VNX OE for Block
(v31)?
A.
Five Flash disks in RAID 5 (4+1); five SAS disks in RAID 5 (4+1); six NL-SAS disks in RAID 6
(4+2).
B.
Five Flash disks in RAID 5 (4+1); six SAS disks in RAID 6 (4+2); six NL-SAS disks in RAID 6
(4+2).
C.
Five Flash disks in RAID 5 (4+1); five SAS disks in RAID 5 (4+1); eight NL-SAS disks in RAID 6
(6+2).
D.
Five Flash disks in RAID 5 (4+1); five SAS disks in RAID 5 (4+1); five NL-SAS disks in RAID 5
(4+1).
answer is C
With the current release, RAID configuration is moved from the pool level to the tier level. Within each tier, users can select from five RAID types, two of which are new. In previous releases, if you chose RAID 5 the VNX would automatically try to make it as close to 4+1 as possible. For RAID 6 it would be 6+2 and RAID 1/0 it would be 4+4. Now you will be able to choose an 8+1 for RAID 5 and 14+2 for RAID 6, although the default will still be the same as it was before – 4+1, 6+2, or 4+4.
