Re: iSCSI minimum PDU length

["Julian Satran" <Julian_Satran@il.ibm.com>]

John,

We are talking about the payload (i.e. DataSegment Length) maximum length 
that a receiver will accept and I suggested
1024 as the minimum value for it.

Julian,
Perhaps I do not understand what you are getting at here, but since there 
will be implementations with only R2T type Sessions, then there should be 
a lot of PDUs that just carry the Command (48 bytes + digest) it seems 
that a 1024 is kind of big.  What am I missing?

With no votes against we have settled (again) on single PDU length (per
connection, per direction) for all types of PDUs.
But I think we erred on the low side by suggesting 64 as a minimum. It is
low (it was mentioned) and bad for text request/response.

How about settling for 1024?
