We have been running NFS and other apps over iWARP 24x7 for the last 6
mos...without the proposed netdev patch. We've run 200+ node MPI
clusters for days and days over iWARP...without the proposed netdev
patch. We ran iWARP interoperability tests across the country between
Boston and San Jose...without ... yes I know ... you get it.
<sarcasm>
News flash...the foundation is built!
</sarcasm>
But! Our stable LAN and the WAN tests didn't often experience MTU
changes, and redirects...but of course we knew these were inevitable. So
our goal was to make iWARP more robust in the face of a more dynamic
network topology. Shutters on the house maybe...I dunno, it's your
analogy ;-)
All that said, the proposed patch helps not only iWARP, but other
transports (iSCSI, IB) as well. It is not large, invasive,
intrusive...hell it's not even new. It leverages an existing event
notifier mechanism.
This patch is about dotting I's and crossing T's, it's not about
foundations.
