Step 4 - Choose Drives

Drives are orderable at the time the array is purchased, or can be added in the future when additional capacity is required. Unlike other HP 3PAR StoreServ Storage systems where drives are sold in magazines of four, HP 3PAR StoreServ 7000 drives are sold as single drives. Note that these drives are only compatible with the M6710 and M6720 drive enclosures.

For each drive type installed in the array, the minimum recommended initial quantity is

SSD and SAS performance HDDs - eight (8) drives* per node pair

Nearline HDDs - twelve (12) drives per node pair

Minimum upgrade quantity is 4 drives per node pair or 2 drives per enclosure, whichever is larger. Best practice is to run Autonomic Rebalance (also known as tunesys) after adding the drives.

RAID 6 is strongly recommended for Nearline drives.

All node enclosures must contain either zero (0) or an even number of drives. All drive enclosures must contain an even number of drives, with a minimum of two. Minimum raw capacity is 1.2TB per node pair.

A best practice is to add equal numbers of drives to all enclosures compatible with the drive type being added.

With a four node configuration, the best practice is to attach the same number and type of drives to each node pair.
