Partitions
3
Library partitioning provides the capability to divide the library’s storage
elements into separate partitions, usable by separate host computers on
the same network. The maximum number of partitions per library is four
partitions; however, the number of partitions is limited by the number of
installed tape drives. For example: in a PX502 with two tape drives
installed, only two partitions would be possible in this library.
Partitioning Requirements
3
The requirements for library partitioning differ depending on the library
interface. Additional equipment may be necessary to allow more than
one partition.
•
Surrogate SCSI interface
- in a library with a surrogate SCSI interface,
there is no additional equipment necessary for library partitioning.
•
Native Parallel SCSI interface
- in a library with a parallel SCSI
interface, you must add a FC1202 Fibre Channel bridge and configure
the Fibre Channel network to include the bridge(s) and host systems.
If you do not have a FC1202 bridge installed, the library is limited to
one partition.
•
Native Fibre Channel interface
- in a library with a native Fibre
Channel interface, you must have a Fibre Channel switch available to
connect to the library Fibre Channel SCB, Fibre Channel hosts, and
native Fibre Channel tape drives. If you do not have a Fibre Channel
switch available, the library is limited to one partition.
PX500 Configurations that do NOT Support Partitioning
3
The following PX500 configurations do NOT support partitioning:
•
Native Parallel SCSI interface
- a parallel SCSI library without a
FC1202 bridge cannot support partitioning.
•
iSCSI bridged Parallel SCSI
- a parallel library with a TC2201 iSCSI
bridge cannot support partitioning.
•
Native Fibre Channel without a switch
- a Native Fibre Channel library
that is not have a Fibre Channel switch cannot support partitioning.
