Crossbow, quo vadis?

Going forward there is a lot of work to do in this space to get additional performance as well as to add some more sexy features. [Read More]

Successful Crossbow beta results

By now we have received feedback from almost all of our Crossbow beta testers and it's been entirely positive so far. A number of folks who are currently running Solaris zones really like the Virtual NIC (VNIC) concept that allows them to consolidate several separate services onto a single machine while guaranteeing the isolation and performance of the VNIC. For hosting companies this means port consolidation, i.e. lower capital cost as well as lower port management cost. Another group likes the significantly reduced latency. In the case of one customer they were able to cut their end-to-end TCP and UDP latency down by more than 50% on their work load. We had generated some similar numbers in our labs before publishing the bits, but of course it's always great to see customers verifying your own numbers. Another beta tester is trying things like using the HW classification capabilities in the NIC to push down firewall functionality into the HW and so on. I'm curious to hear back from them in the next few weeks.

At the same time the development team is slaving away to get Crossbow into Solaris. Still a few more bugs to be resolved and a bit more performance work ahead, but things are going rather well right now. Keep your fingers crossed!
