Overview
19 SSL1016 Tape Autoloader Reference Guide
Ethernet Connection
The ethernet connection lets you connect the autoloader to a network, enabling
remote administration. Via the network, the autoloader can access an SNMP
server and a Simple Network Time Protocol (SNTP) time server. The ethernet
connection supports File Transfer Protocol (ftp) and Hyper Text Transfer Protocol
(http). You can download firmware updates using ftp and perform administrative
tasks, including diagnostics, using http.
SCSI Connection
The autoloader supports both low-voltage differential (LVD) and single ended
(SE) connections, however, data transfer rates and SCSI cable lengths will be
reduced if an SE connection is used on an SSL1016 with an SDLT 320 drive. An
LVD connection is recommended for the SSL1016 with an SDLT 320 drive.
For best performance, an LVD connection using an Ultra3 adapter is
recommended for the Ultrium 460 drive.
A 68-pin VHDCI connector links the autoloader to the external host server. A
second VHDCI port is used for termination or to connect another SCSI device. If
other SCSI devices will be sharing the bus, make sure that SCSI cable length
limits are not exceeded and that the other devices will not impact the performance
of the tape drive by utilizing too much of the bandwidth.
Note: Adding a SE device to an LVD bus causes the entire bus to operate at SE speeds
and with SE cable length requirements.
DCA Switches
The switches on the back of the drive carrier assembly (DCA) have no user
function at this time.
