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
