Remote Host Access
The
Remote Host Access
page allows you to configure virtual media changers and tape drives on the
DXi4700 to communicate with Fibre Channel hosts (initiators). You can add, edit, and delete hosts as well
as view Fibre Channel target ports on the DXi.
If you do not create and associate a host access group with a partition, the virtual devices are not visible from
the host, and drives cannot be destinations for move operations.
Fibre Channel Host Bus Adapters (HBAs) - Data Payload Size
The Fibre Channel HBAs used on the DXi4700 have a maximum data payload size per frame of 2048
bytes. The Fibre Channel specification allows a maximum data payload size of 2112 bytes per frame.
Fibre Channel HBAs used on backup hosts should be configured to use a maximum data payload size of
2048 bytes per frame. Failure to match the backup host maximum data payload size to the DXi4700
maximum data payload size may result in stalled data transfers.
