Description
For read data, the value in the MAXIMUM BURST SIZE field
contains the maximum amount of data that is transferred during a
connection by an SSP target port per I_T_L_Q nexus without
transferring at least one frame for a different I_T_L_Q nexus. If the
drive:
a) has read data to transfer for only one I_T_L_Q nexus, and
b) has no requests to transfer write data for any I_T_L_Q nexus;
then the drive will prepare to close the connection after the amount
of data specified by the MAXIMUM BURST SIZE field is transferred
to the SSP initiator port.
For write data, the value specifies the maximum amount of data that
an drive requests via a single XFER_RDY frame.
This value is specified in 512 byte increments. A value of zero in
this field specifies that there is no maximum burst size.
The maximum value for this field is 400h.
Note that attempting to set Maximum Burst Size to a value greater
than supported by the drive will return check condition with sense
RECOVERED ERROR; ROUNDED PARAMETER.
Not supported by the drive.
All reserved bits must be 0.
