Library Interfaces; Drive Types - StorageTek L700 Service Manual

Overview
MPC card spares will be available indefinitely. You should replace an MPC card
with an MPC card and replace MPCL cards with MPCL cards.

Library Interfaces

The L700e can operate on the following interfaces:
• High Voltage Differential (HVD)
• SCSI Low Voltage Differential (LVD)—requires the addition of MPV and
MPW cards for MPC cards only; new MPCL cards, however, can operate as
native LVD/SE.
• Single-ended SCSI.
• Fibre Channel with the addition of MPU and MPV cards

Drive Types

The following drives may be installed within the L700e:
• T9x40 – HVD SCSI or Fibre Channel
• T9840B – HVD SCSI, Fibre Channel, or ESCON
• DLT 7000 or DLT 8000 – HVD SCSI only
• The SDLT 320 model—Backward Read Compatibility (BRC – ability to read
previously written tapes on DLTIV media)
• IBM Ultrium
•
•
• Hewlett Packard Ultrium:
•
•
• Seagate Ultrium – LVD or HVD (determined by model number)
CAUTION:
System fault: For either HVD or LVD operation, the server must have a
corresponding (matching) host bus adapter.
SCSI drives and media can be intermixed.
The exchange rate for moving tapes from cell to cell is 450 cartridges per hour.
