The latest revision of Open-E does not accept previous values for MaxBurstLength. The error message references RFC3720. However according to the RFC the maximum value should be 16777215. But, in this case the value entered is 16776192 which is less than the stated maximum. This value is posted on a number of forums as a recommended value for Open-E. Please advise.
Thank you.
it must be divisable by 1024 to meet the RFC.
Try these:
===
maxRecvDataSegmentLen=262144
MaxBurstLength= 1048576
Maxxmitdatasegment=262144
FirstBurstLength=65536
DataDigest=None
maxoutstandingr2t=8
InitialR2T=No
ImmediateData=Yes
headerDigest=None
(deprecated)Wthreads=8
===
Thank you for the recommended values. Are these also recommended for 10 Gb connections?
(However, 16776192 / 1024 = 16383).
[QUOTE=Gr-R;15541]it must be divisable by 1024 to meet the RFC.
1024 * 1024 = 1048576(its exponential, actually)
Yes, its good for 10GBe
Thanks again for the quick follow-up. Is there any way to set different default values for iSCSI target parameters so when creating new targets they use these values instead of the default (a real issue as changing parameters requires disabling fail-over).
unfortunately, no.
We use the defaults we use because not all initiator systems allow these values to be manipulated. Thus, standardization ;)
