Minimum of zero (0) drive enclosures, maximum of (18) attached to QR485A.
Drive enclosures are connected in daisy chains from the SAS ports of the
controller nodes.
The best practice is to balance the drive enclosures across the SAS ports,
remembering that the controller node enclosures include (24) drives attached to
the SAS port labeled DP-1.
The best practice when including LFF and SFF drive enclosures in the same array
is to arrange them in the rack so that all of the 2U enclosures that belong to one
node pair are together and all of the 4U enclosures for that node pair are
together. When connecting the backend SAS cables, intermix the M6710 and
M6720 enclosures on each SAS port.
With a four node configuration, the best practice is to attach the same number of
drive enclosures to each node pair.
To achieve highest availability in multi-enclosure configurations, configure a
minimum of two (2) enclosures per node pair for RAID 1, a minimum of four (4)
enclosures per node pair if RAID 5 is included, and a minimum of three (3)
enclosures per node pair if RAID 6 is included. Include enclosures containing node
pairs in the count with the M6710 enclosures.
Drive bays that are not filled with a drive must be covered with a drive blank to
preserve proper air flow.
If future capacity upgrades are expected, include enough Drive Enclosures so
that there are some empty bays in each enclosure after all drives are added.
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,
