Configuration
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.
Small Form Factor (SFF)-specific configuration practices
SFF drives may be loaded into the Storage Base enclosures, the Upgrade
Node Pair enclosure and the M6710 drive enclosure.
SFF drives must be loaded in pairs of identical drives, beginning with the
leftmost slot, slot 0, and filling to the right, leaving no empty slots
between drives.
Large Form Factor (LFF)-specific configuration practices
LFF drives may be loaded into the M6720 drive enclosure.
LFF drives must be loaded in pairs of identical drives starting at the
bottom of a column, leaving no empty slots between drives in the column.
Columns of drives in the M6720 enclosure must be of the same type (SSD
or NL) and, for HDDs, the same rotational speed. Drives of different types
may not be mixed in a single column. It is permitted to have empty
columns between columns containing drives. Different columns do not
have to contain the same number of drives.
An all LFF drive configuration is permitted, leaving the Storage Base
Enclosure empty.
SSD specific configuration practices
SSD-only configurations are permitted.
Maximum of 120 SSDs per node pair.
The SFF and LFF SSDs allow the user to create SSD volumes that stripe
across SFF and LFF enclosures.
* 8 drives support RAID 1 and RAID 5. For RAID 6 choose 12 drives.
