Information and first hand experience on the Sun Fire T2000 is slowly beginning to appear from other ASF people. Sun sparked it off with their 60 day free trial and now things are beginning to happen.

Ian Holsman signed up for the trial and started his SunFire Fanatics forum to discuss ideas about benchmaking the T2000s.

Colm MacCarthaigh already got his T2000 and is putting it through some heavy testing. He says that it "can probably comfortably saturate a 10Gigabit/sec interface" which is not bad at all - I'm looking forward to seeing what other numbers will emerge from his benchmarking because Heanet move an impressive amount of data through their mirrors.

The people got one too and Ask Bjørn Hansen has been blogging about it. It will be interesting to see what they make of it as I imagine their workload matches what we see at the ASF.

We're not signed up for the trial at the ASF. We've got enough other things to do on the infrastructure side that playing with new hardware isn't really an option. If anything, I would be tempted to sign up myself just to prove that HTTPD would really fly with event and worker mpm rather than prefork that is shipping with Solaris. I could easily see a use for a couple or more of T2000s if we could get them on a permanent basis. Splitting services between .us and .eu would greatly improve our infrastructure and with our current setup of having no hands on site, having hardware covered by a service contract would be a great improvement.
Thinking with my "enterprise HA" hat on, it would be interesting to see how far a pair of T2000s set up with shared storage and Sun cluster could go hosting our services seperated into zones. Zone Migration is another thing that fits nicely into the picture and would make moving or cloning services between locations a whole lot easier.

It will be interesting to see what the future brings and wether there is any truth in the latest rumors from The Register about an upcomming four-way UltraSPARC T1.

interview - followup

In the interview, I mentioned that lots of the things I felt was missing is already in the works. Reading an interesting piece by Dan Price about Zones Development: You're invited I found a link to some of the Zones Project Documents - looking at that page, they've already covered one of my wishes with "Zones move and clone" and "Zones migration (attach/detach)". The other zones related feature I'd love to see is dtrace within zones, which is listed as being in development. All in all, things are looking good to me and I've got my fingers crossed hoping that all of it will be in Update 2.

Another interesting bit arrived on zones-discuss (at) just as I was typing this:

From: Dan Price
Subject: [zones-discuss] The migration is on...

As of right now, we've completed a move of our Sun-internal
zones-interest list to zones-discuss (at)

Tim Bray from Sun interviewed me about our use of Solaris zones at the ASF. Sun deserve a lot of credit for donating the machine to us, it is doing a lot of good for many projects there.

UPDATE: A few people have been blogging about this interview already

Justin Mason - We Win
David Reid - credit where credit is due
Bertrand Delcretaz - Behind the scenes of the ASF zones server
Alan Hargreaves - Apache Software Foundation and Solaris 10
