Planning the FC configuration
You can 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.
Direct connection
The host must have a 2 Gb, 4 Gb, 8 Gb, or 16 Gb FC HBA. A 4 Gb HBA is recommended for
LTO-4 tape drives. An 8 Gb or faster HBA is recommended for LTO-5, LTO-6, and LTO-7 tape
drives. To verify that an HBA is supported on your server and qualified for the library, see the
Data Agile BURA Compatibility Matrix at:
http://www.hpe.com/storage/buracompatibility
A server that has FC-attached hard drives should have 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
You must provide an FC cable 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.

* The LTO-5 Ultrium 3000 half-height drive is shown as LTO-5 HH .
Planning the SAS configuration
The server must have an Hewlett Packard Enterprise or third party SAS host bus adapter with
an external connector.
The library uses two SCSI logical unit numbers (LUNs) and requires an HBA with multiple LUN
support. Most Hewlett Packard Enterprise SAS RAID controllers support tape devices; many
other SAS RAID controllers do not support tape devices. To verify the specifications of your HBA
or find a list of compatible HBAs, see the Data Agile BURA Compatibility Matrix at:
http://www.hpe.com/storage/buracompatibility
CAUTION: Do not connect the library to a SAS RAID controller unless the Data Agile BURA
Compatibility Matrix shows that the controller is qualified with the library. The server might not
be able to boot when the library is connected to a non-supported SAS RAID controller.
