Planning
This chapter provides information for consideration when planning for the
installation of the StorageTek SL150 Modular Tape Library System.
Multiple LUN Support
The SL150 Modular Tape Library uses a single SCSI ID and two logical unit numbers
(LUN). LUN 0 controls the tape drive and LUN 1 controls the robotics. The tape
drives in the base module provide the bridging function and must be connected to an
HBA supporting multiple LUNs (also referred to as LUN scanning).
SAN Connection
The library can be connected to the host HBA through a storage area network (SAN).
Configure zoning on the Fibre Channel switch so only the backup servers access the
library.
The half-height FC tape drive has an 8 Gb/s data interface.
Serial Attached SCSI (SAS)
SAS uses serial connections, with a direct connection between the host server and
each of the storage devices. SAS signal rates require clean connections and a
minimum number of connections between the HBA and the SL150 Library. Oracle
recommends a maximum SAS cable length of six meters.
The half-height SAS tape drive has a 6 Gb/s data interface.
Oracle SAS HBAs:
3Gb (SAS-1):
• SG-XPCI8SAS-E-Z
• SG-XPCIE8SAS-E-Z
• SG-XPCIE8SAS-EB-Z
6Gb (SAS-2):
• SGX-SAS6-EXT-Z
