# various iSCSI parameters
# (not all are used right now, see also iSCSI spec for details)
#MaxConnections 1
#InitialR2T Yes
#ImmediateData No
#MaxRecvDataSegmentLength 8192
#MaxBurstLength 262144
#FirstBurstLength 65536
#DefaultTime2Wait 2
#DefaultTime2Retain 20
#MaxOutstandingR2T 8
#DataPDUInOrder Yes
