Standard Installation Procedure
1-24 Revision L 96053
The drive interfaces are SCSI high voltage differential (HVD) or SCSI low voltage
differential (LVD). The HVD interface allows longer cable lengths, but throughput is
slower than with the LVD interface. The LVD interface restricts cable lengths, but
provides faster throughput.
The following table shows the types of drives and the interfaces that are supported.
