The tape drive is

operating more slowly

than indicated in its

performance

specification

Your host bus adapter may

be limiting the speed, or

you may be using an

incompatible cartridge.

• Check the host bus adapter documentation for

parameter settings.

• For the best performance, make sure the SCSI

controller card can operate at 320 MB/second.

Limit the number of tape drives on SCSI bus;

Quantum recommends one DLT-S4 tape drive

per bus, with a maximum of two DLT-S4 tape

drives per bus.

• Ensure that the tape drive is properly defined for

the host system. If the tape drive is not defined

within the system, the host adapter does not

interact well with the tape drive.

• Ensure that the host bus adapter card and the

SCSI bus are operating in Ultra320 mode.

• Check the host block size. The DLT-S4 tape drive

supports block sizes up to 16 MB. In general, the

larger the block size, the better the throughput.

Many older software applications default to a

512-byte block size, which results in poor

performance.

• Ensure that you are using a cartridge that is

compatible with the tape drive.
