Re: profiles - a way to simplify iSCSI

[julian_satran@il.ibm.com]

Scott,

I assumed (rightfully) that we are talking about "different profiles".
What I had in mind was more of a "set of levels".

Level 0 - only mandatory feature.
Level 1 = Level 0 + all the optional

A profile 0 device will talk to any device as if is a profile 0 (not using
any optionals).
A profile 1 can talk using profile 1 features only to a profile 1 but it
can talk also to a profile 0
by avoiding all the optionals.

The gain is in simplifying testing and predicting feature interaction (at
the cost of flexibility).

Regards,
Julo

its very straight forward - if you have profiles then it may become
common that one ips devide will not be able to interopoerate with anothe
ips device because they implemented different profiles - see X.400
for a worked example
