IBM Ultrium Internal Tape Drive T200, Справочное руководство

Страница: 45 / 126

The Maximum Burst Size field for the SCSI parallel interface indicates (in multiples
of 512 bytes) the number of bytes that the drive should attempt to send or receive
between disconnects. The default is 0, which implies that the drive may send bursts
of data at any size.
The Maximum Burst Size field for the Fibre Channel interface indicates the
sequence size that the drive should attempt to use when transferring data. Any
value is allowed and ignored. The value for the Maximum Burst Size field is stored
for each initiator.
The Buffer Full Ratio and Buffer Empty Ratio fields should be 0, since buffer
management is controlled by the drive.
The Bus Inactivity Limit, Disconnect Time Limit, and Connect Time limit fields are
not supported and should be set to 0.
The Data Transfer Disconnect Control field is not supported and should be set to 0.

A data compression enable (DCE) bit of 1 indicates that data compression is
enabled. The default for DCE is 1. If DCE is 0, the drive uses Scheme 2 of the
LTO-DC algorithm (passthrough mode).
No other fields are changeable.
