Parallel SCSI HP Smart Array controllers, RAID controllers, and most on-board HBAs do not support
multiple LUNs. Refer to the EBS matrix at
http://www.hp.com/go/ebs
for current HBA compatibility
information.
IMPORTANT:
The Autoloader requires an HBA that supports multiple LUNs, which is also called “LUN scanning.”
Interface specifications and requirements for Fibre Channel
drives
The Fibre Channel tape drive can be connected directly to the server with a host bus adapter (HBA)
or through a storage area network (SAN).

LTO generation
2 Gb, 4 Gb, 8 Gb
LTO-5
If you plan to connect the Autoloader directly to the server, you will need a 2 Gb, 4 Gb, or 8 Gb
Fibre Channel HBA. 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 Autoloader.
In a SAN installation, all switches between the host and the Autoloader must be of the appropriate
type. For example, a 2 Gb switch in the path may result in performance degradation when backing
up highly compressible data to a 4 Gb tape drive. Configure zoning so only the backup servers may
access the Autoloader.
Interface specifications and requirements for SAS drives
The server must have an HP or third party SAS host bus adapter with an external connector.

LTO generation

The device uses multiple LUNs to communicate with the Autoloader. Most SAS RAID controllers do
not support multiple LUNs. Check the EBS matrix at http://www.hp.com/go/ebs to find a SAS HBA
that is supported on your server and qualified with the Autoloader.
Most SAS HBA ports provide four SAS channels. The Autoloader only uses one channel. The HP cable
supplied with the Autoloader has one connector on each end, using only one of the four channels.
To use the other channels, you can purchase a SAS fanout cable, which will connect up to four SAS
tape drives to a single HBA port. When using a different cable, verify that the mini-SAS connector
for the tape drive end is keyed for location 4.
