DS3200/3300/3400 Software Feature Pack
You must enable this feature before any other premium feature can be applied - it is a
pre-requisite to all the other features listed here. Out-of-the-box, the DS3300 and DS3400
support two storage partitions only, whereas the DS3200 supports four. The Software Feature
Pack increases the number of supported partitions on the DS3300 and DS3400 from two to
four.
Note that installing the Software Feature Pack requires the enclosure to be rebooted.
DS3000 Partition Expansion License
As standard configuration, four storage partitions are enabled on DS3200 and two on
DS3300/DS3400 (this increases to four with the use of Software Feature Pack, as stated in
the section above).
The maximum number of storage partitions is 16 on all DS3000 products. Use the DS3000
Partition Expansion License to enable all 16 storage partitions.
DS3000 FlashCopy Expansion License
source logical drive
This feature enables FlashCopy. FlashCopy is a point-in-time copy of a .
The FlashCopy logical drive becomes available almost instantaneously.
FlashCopy repository
FlashCopy requires the use of a defined , which will contain the original
content of the data that has since been altered. FlashCopy logical drives are often used as a
source for a backup operation. They can also be used to simply and quickly roll back to an
original data state, thus providing a restore point. However, if the source logical drive is lost,
the point-in-time FlashCopy will be lost as well. For more information on FlashCopy, see 8.4,
"Create FlashCopy Logical Drives" on page 170.
With this premium feature enabled, you can configure up to 64 FlashCopies.
DS3000 VolumeCopy License
VolumeCopy is a way to provide a complete point-in-time copy of a source logical drive. As
opposed to FlashCopy (where only the original values of changed data are copied to the
repository), the whole source logical drive is copied to target. You can use this functionality for
data replication, relocation, backup, or to restore snapshot data to the original logical drive.
The time required to establish a copy will depend on the size of the source data and the
operation priority settings. While establishing the copy, the source logical drive will be in
read-only state.
Once all the data is copied to the target, the target will remain available if the source logical
drive is lost. For more information on VolumeCopy, see 8.5, "Create Logical Drive Copies" on
page 184.
The VolumeCopy premium feature allows for up to 128 VolumeCopies. Be aware that
FlashCopy is a prerequisite for VolumeCopy.
DS3000 FlashCopy VolumeCopy License
As stated above, FlashCopy premium feature must be enabled before you can enable and
use VolumeCopy. For this reason, IBM provides the FlashCopy VolumeCopy license; this is
actually a bundle of both premium features.
DS3000 EXP3000 Expansion License
Out-of-the-box DS3000 configuration does not support an EXP3000 attachment - the
EXP3000 Expansion License is required before you can connect any EXP3000s. This
