Criteria Definition
Air quality
• Place the library in an area with minimal sources of particulate
contamination.
• Avoid areas near frequently used doors and walkways, stacks of supplies
that collect dust, printers, and smoke-filled rooms.
• Excessive dust and debris can damage tapes and tape drives.
Humidity 20-80 percent RH non-condensing
Module and rack layout guidelines
When possible, install the base module near the middle of the rack at a convenient height for viewing and
operating the OCP and accessing the mailslot.
The library supports up to 3 expansion modules above and 3 expansion modules below the base module, for
a total of 7 modules. Each module occupies 3U.
For maximum library expansion, install the base module as the centered module of the rack, allowing 9U
above the top of the base module and 9U below the bottom of the base module.
If the library will be sharing the rack with other equipment, place heavy devices, such as disk arrays, in the
bottom of the rack to reduce the chance of the rack tipping.
FC connection information
Connect the FC tape drive directly to the server with an HBA or indirectly through a SAN with an FC switch.
Most supported tape drives have two FC ports. Only one port can be used at a time, but both ports can be
connected for path failover or with software that supports multipath. If you are using only one port, you can
use either port. Path failover is a licensed library feature.
Direct connection
The host must have a 2 Gb, 4 Gb, 8 Gb, or 16 Gb FC HBA. An 8 Gb or faster HBA is recommended for all
supported tape drives. To verify that an HBA is supported on your server and qualified for the library, see the
StoreEver Support Matrix at: https://www.hpe.com/storage/StoreEverSupportMatrix
A server that has FC-attached hard drives performs best with at least two FC ports. Using the same FC port
for disk and tape drive access can cause performance degradation.
SAN connection
All switches between the host and the tape drive must be of the appropriate type. A 2 Gb switch in the path
might cause performance degradation when backing up highly compressible data.
Configure zoning on the FC switch so that only the backup servers can access the tape drive. For more
information, see the switch documentation.
Cable requirements
An FC cable is required for each FC port you plan to use. The tape drive has an LC-style connector. The
maximum cable length is based on the tape drive and external cable type.
