What is partitioning?
Partitioning allows you to create separate, logical tape libraries from a single physical tape
library. Logical libraries (partitions) behave like a physical library to the backup and restore
applications. Using the advanced version of Secure Manager in conjunction with HP
StorageWorks Command View ESL, you have the option of partitioning an ESL9000-Series or
ESL E-Series library. For more information about Secure Manager and Command View ESL,
refer to chapter 4, “Advanced Features,” of the HP StorageWorks Interface Manager and
Command View ESL User Guide.
Benefits
Partitioning has the following benefits:
■
Allows the use of mixed media—Partitioning a physical library with mixed drive and
media types allows the different types of media and drives to be logically separated. This
reduces the complexity of configuration within the backup application. Keeping the
media and drives separated also greatly reduces the chance of media being inserted or used
in the wrong drive.
■
Allows two applications to share one library—Large datacenters often use more than
one backup application to protect their data. Library partitioning provides a practical way
to access the physical library from two different applications without conflict. For more
information about application support, refer to the EBS compatibility matrix found at the
following web site:
ht p://h18006.www1.hp.com/products/storageworks/tapecompatibility.html.
■
Allows two SANs to share one library*—A storage resource, such as an HP
StorageWorks ESL E-Series library, can be shared without merging two SANs together.
Library partitioning enhances this ability by segmenting the physical library into logical
libraries that can be shared between two SANs and their respective backup applications.
Note: * Before two SANs can share one physical library, the library that is being shared must have
the robotics controller connected to an HP StorageWorks e2400-160 Fibre Channel interface
controller. The ESL E-Series libraries are shipped with the e1200-160 Fibre Channel interface
controllers by default, so an upgrade may be required to enable two or more SANs to share the
library. For more information about upgrading the interface controller, refer to the Connecting Two
SANs to ESL E-Series Robotics poster.
Partitioning considerations
When partitioning a library, consider the following:
■
An ESL E-Series or ESL9000 library can have up to six partitions. Each partition must
have at least one drive and one slot, and can have no more than one picker (also referred to
as a robotic device or medium changer) assigned to it. Mailslots are optional.
■
Tape drives and “normal” slots can be placed arbitrarily, in any grouping, into any
partition, with the following limitations:
— Up to ten separate, contiguous slot “ranges” (groups) can be assigned to a partition. A
range is a slot or contiguous group of slots. For example, selecting slots 1-25
constitutes one range. Selecting slots 1, 6, and 22 constitutes three ranges.
