Scalar i6000 Partitions

Overview

Partitions are logical sections within a physical library that appear as multiple separate libraries for purposes of data management, access by multiple users, or dedication to one or more host applications. You can use partitions to control access to portions of the library by granting permissions to user accounts to access certain partitions.

The available types of partitions are:

Standard

These partitions are visible to hosts and are used for normal backup operations.

Active Vault

These partitions allow you to keep tape cartridges vaulted within a physical library, rather than having to move them to other locations. Cartridges stored in an active vault partition are not managed by a host and the partition contains no tape drives.

Extended Data Lifecycle Management (EDLM)

These partitions allow for media to be moved into them for the purposes of scanning by EDLM drives. An EDLM partition only contains EDLM drives.

Automated Media Pool (AMP)

Allows you to pool media, such as scratch tapes, within a library managed partition to facilitate selective tape cartridge assignments from the media pool to standard partitions without the need for operator intervention to physically load or import additional tape cartridges into standard partitions.

Instead of requiring physical import operations to each partition, the AMP can contain a number of tape cartridges that can be moved or assigned to a partition via a user-interface-initiated media move or magazine assignment selection at any time.

In addition, the AMP feature allows for the creation of standard partition AMP extensions such that a standard partition gets created with a specified number of actual and accessible storage elements as well as logical, inaccessible element extensions. As a standard partition requires additional accessible storage elements, logical elements can be associated with physical magazines from the AMP such that the logical element extension becomes an actual physical storage element that can now report an accessible status to a host.

Note: Manual movement between library managed partitions and standard partitions will require inventory reconciliation with the backup application managing the standard partition.

AMP Benefits

  • You can easily move and reassign tapes from the AMP to standard partitions and from standard partitions to the AMP. This allows you to adjust the amount of media within a partition as needed without performing import/export operations.
  • The AMP can provide a “staging area” for scratch tapes and tapes that are no longer needed for backup. When a tape is needed by a partition, it can be moved from the AMP instead of having to be physically imported into the library partition.
  • The number of partition accessible storage units can be expanded or reduced as needed without having to reconfigure the library, partition or host application.
  • Tapes can be auto-imported from an AMP partition to standard partitions based on filters set up to associate tapes with standard partitions by barcode range.
  • Tapes can be auto-exported to an AMP partition via policies to redirect standard partition export MOVE requests.

AMP - Requirements

  • The AMP feature requires a Partition license
  • Multiple automated media pool partitions can exist. Since they are library managed partitions, an AMP exists solely within the library and is not accessible to hosts.
  • You may have multiple AMP partitions. However, the total number of standard and library managed partitions cannot exceed the maximum of 32 partitions.
  • All storage slots in the AMP partition must be licensed (via COD).
  • AMP partitions do not contain drives.
