iSCSI Immediate Data and Unsolicited Data Features
Cisco MDS SAN-OS Release 2.1(1a), and later, supports the iSCSI immediate data and unsolicited data
features if requested by the initiator during the login negotiation phase. Immediate data is iSCSI write
data contained in the data segment of an iSCSI command protocol data unit (PDU), such as combining
the write command and write data together in one PDU. Unsolicited data is iSCSI write data that an
initiator sends to the iSCSI target, such as an MDS switch, in an iSCSI data-out PDU without having to
receive an explicit ready to transfer (R2T) PDU from the target.
