Direct Connection; San Connection; Choosing A Location; Library Extender Supported Configurations - HP StorageWorks MSL2024 User's And Service Manual

You must provide a Fibre Channel cable for each tape drive in the Library. The tape drive has an
LC-style connector.
Each full-height Fibre Channel tape drive in the Library has two Fibre Channel ports. Only one port
may be used at a time, but both ports can be connected for path fail over if your application supports
path fail over. If you are using only one port, you can use either port.

Direct connection

If you plan to connect the Library directly to the server, you will need a 2 Gb, 4 Gb, or 8 Gb Fibre
Channel HBA. A 4 Gb HBA is recommended for LTO-4 tape drives. An 8 Gb HBA is recommended
for LTO-5 tape drives for optimal performance. Check the EBS matrix at http://www.hp.com/go/ebs
to verify that your HBA is supported on your server and qualified for the Library.
A server that uses Fibre Channel disks needs at least two FC ports. Using the same port for disk and
tape access will cause performance degradation.

SAN connection

All switches between the host and the Library must be of the appropriate type. A 2 Gb switch in the
path may result in performance degradation when backing up highly compressible data.
Configure zoning on the Fibre switch so only the backup servers may access the Library. See the
switch manual for information on zoning.

Choosing a location

If you plan to mount the device in a rack, select an open rack location, ideally near the center of the
rack or higher, with access to the host server and a power outlet.
If you plan to set the MSL2024 or MSL4048 Tape Library on a table in the tabletop conversion cover,
select a level area large enough to support both edges of the device with access to the host server
and a power outlet. Do not set the MSL8048 or MSL8096 Tape Library on a table or other surface.
IMPORTANT:
The MSL8048 and MSL8096 Tape Libraries must be mounted in the enclosed rack rails. The MSL2024
and MSL4048 Tape Libraries must be mounted in the enclosed rack rails or in the optional tabletop
conversion cover. Placing the Library on a surface, such as a table top or rack shelf, without the
tabletop conversion cover could result in Library errors.
If installing the Library with the Library Extender, determine the master and lower units, and install
them in adjacent rack locations, with the master Library directly above the lower Library. To install
the Extender, both Libraries must be installed in the rack rails.
