create a single storage partition. If you need additional storage
partitions, you must purchase a Shared Library Services (SLS)
activation key. Refer to Enabling BlueScale Software Support, Options,
and Upgrades on page 108 for information about purchasing and
entering activation keys.
 Libraries running BlueScale software versions earlier than
BlueScale12.6.3, are limited to eight storage partitions.
 Libraries using BlueScale12.6.3 or later can have a maximum of 16
storage partitions.
 Cleaning partitions do not require an SLS activation key and
Notes:
do not count toward the partition maximum.
 The more partitions in a library, the longer each move can
take. If move requests can be sent to several partitions at
once, you may need to increase the timeout setting in your
storage management software.
 With BlueScale12.7.00 to BlueScale 12.8.01.04, the maximum number
of physical exporting devices (RIMs) supported by the library is six.
If the library contains RIMs in excess of the six exporters, the
additional RIMs can be used for failover (see Controller Failover on
page 78).
 With BlueScale12.8.03 or later, the maximum number of physical
exporting devices (RIMs or drives) supported by the library is 12.
A single RIM can export up to eight partitions, but still only
Note:
count as one exporter; a single RIM2 can export up to 16
partitions, but still only count as one exporter.
 If the library has Thin Provisioning enabled, a single RIM can export
60,000 elements. A single RIM2 does not have this limit.
 If desired, you can configure multiple exporting controllers to a
single partition and use your host software to export the same
changer interface over the controllers to provide redundancy.
