Description
Controls the HeaderDigest usage by the iSCSI target portal group endpoint.
Controls the DataDigest usage by the iSCSI target portal group (TPG) endpoint.
Controls the usage of Multiple Connections per Session (MC/S). Initiator and
target negotiate the maximum number of connections requested and/or
acceptable.
Turns the default use of R2T (Ready to Transfer) on or off for unidirectional and
the output part of bidirectional commands.
Indicates whether the initiator and target have agreed to support immediate
data on this session.
Maximum data segment length in bytes the initiator and target can receive in
an iSCSI Protocol Data Unit (PDU).
Maximum data segment length in bytes that can be sent.
Maximum iSCSI data payload in a Data-In or a solicited Data-Out iSCSI
sequence, in bytes.
Maximum amount in bytes of unsolicited data an iSCSI initiator can send to the
target during the execution of a single SCSI command.
The R2T PDUs that can be in transition before an acknowledge PDU is received.
Maximum number of commands queued to any session of this target.
Synchronous file I/O provides reliability but slower performance. Asynchronous
writes are faster, but buffered data will be lost if a power outage occurs.
Increases performance. This cannot be used when block I/O is selected.
Number used to identify a local unit.
