CHAPTER 6

SCSI and Controller

Interface Specification

6.1

SCSI Interface Type

The SDLT drive is available in either of two possible SCSI interface versions;
these versions provide three possible SCSI interface types:

•

Multimode Single-Ended (MSE) card provides one of two interfaces

Low Voltage Differential (LVD) running at 80 MB/second, or

Single Ended (SE) running at 40 MB/second.

•

High Voltage Differential (HVD) card running at 40 MB/second.
