Performance Specifications

CHAPTER 7 SPECIFICATIONS

This section describes the performance specifications for the tape drive. The tape drives are factory tested to these specifications using VXAtape XTape media.

DATA TRANSFER RATES

Table 7-2lists the data transfer rates that the High-density, LVD tape drive can achieve.

Table 7-2Data transfer rates in megabytes per second

Read a, b		Write a, b		Burst transfer rate
VXA-3 Format	VXA-2 Format	VXA-3 Format	VXA-2 Format	VXA-3 Format	VXA-2 Format

12.0 MB/secc	6.0 MB/sec	12.0 MB/sec	4.5 MB/sec	160 MB/sec	160 MB/sec

aHost matching.

bWhen attached to a High-density LVD SCSI bus. All sustained data rates are dependent on the capabilities of the SCSI bus (for example, an Ultra2 SCSI bus is limited to less than 40 MB/second).

cOne megabyte equals 1,000,000 bytes.
