ISCSI Settings

[astasny]

hi.

the default iscsi settings between dss v6 and vmware 5 seems different for me.
can anyone tell me which options i have to adjust. (if necessary)

Iscsi Settings:
Vmware DSS V6
Header.Digest false false
Data.Digest false false
MaxOutstandingR2T 8 1
First Burst Length 262144 65536
Max burst Length 262144 262144
MaxXmitDataSegLen ------ 262144
MaxRecvDataSegLen 131072 8192
Init2Rt greyed false true
Immediate data greyed true false
Delayed Ack true ------


thanks
Andreas

maxRecvDataSegmentLen=262144
MaxBurstLength=16776192
Maxxmitdatasegment=262144
FirstBurstLength=65536
DataDigest=None
maxoutstandingr2t=8 <<(maybe try 16)>>
InitialR2T=No
ImmediateData=Yes
headerDigest=None
Wthreads=8

The values need to match at the target and initiator.

thanks for the answer.

And about the Delayed ACK it is always disabled (or in other words TCP_NODELAY is always enabled) in SCST (the iSCS target service used by DSS).
