It's been a while, so here's a general update about how things are going around here in SETI/BOINC server land.
First off, our cooling situation vastly improved yesterday. Due to low levels of freon the air conditioner in our server closet hasn't been doing its job. This was spotted and fixed, and immediately all system temps went down as much as 8 degrees (Celsius) and various fibre channel warnings disappeared from our system logs. Good.
As SETI@home classic ramps down and more users join SETI@home/BOINC, the database server is keeping up, but the replica is having a harder time of it. Right now the replica is not being used for production (only for backups), so this isn't a major problem yet.
The data server (which handles uploads/downloads) is also on the brink of being unable to keep up with demand, so we are going to deal with this as well. Fairly soon, the master science database will move off of galileo (a 6 CPU/6 GB Sun E3500) and onto castelli (an 8 CPU/7 GB Sun E3500 which faster/larger/RAIDed disks). Then galileo will shed its large, unwieldy disk enclosures and be in the running as a good replacement for the data server (currently a 2 CPU/2 GB Sun D220R). We have the option of splitting uploads and downloads onto separate servers as well.
The web server is doing just fine, but in anticipation of higher demand and possibly more site features we are working on setting up a bank of SunFire V100s to be backup web servers. Or they may become splitter servers, in case we can't keep up with workunit production demand.

In preparation for shutting down SETI@home Classic (in about 1 month, hopefully) we're trying to make sure that SETI@home Classic accounts are linked to the proper SETI@home/BOINC account. This is a bit complicated because of email address changes. See our current transition plan.
Neither of these, nor the updated transition-plan, was posted in "classic", so if they wants to "give plenty of advance warning" the "in a month" is maybe when they hopes all the server-shuffling is done and they are ready for sending out the mass-email to all users with exact shutdown-timeline.Okay - before anybody gets too excited, these are just some baby steps as we prepare for the real migration. We have a lot of cleanup to do. Basically, having old classic stats in the BOINC profiles confused/infuriated users who were making the switch over to BOINC. As well, I'm personally sick and tired of dealing with the slow and impossible-to-administrate classic message boards so might as well start requesting that people use these boards which work a *lot* better.
It's not like we're shutting things down tomorrow. We'll still give plenty of advance warning.
