sad Technical difficulties occurred............please stay tuned during this temporary slow-down [Resolved]

Hi Everybody,

Last week the RAID server that stores all of our FightAIDS@Home results and that we use for transfering data to and from the World Community Grid died on us. Some catastrophic hardware failure occurred, and now our server is broken. We are currently trying to fix the issue and to recover all of the FAAH data that was on that server when it died. There are back-up copies of all of the results that your calculations have produced for us, but it will take a few weeks to fix the hardware issue(s) and to restore the ~ 4 TeraBytes of data that were on that server.

While we fix the server and rescue the data, we set up a small, temporary server that allows us to keep submitting new jobs to the World Community Grid. But since we do not yet have a new, large server for storing the incoming results, the WCG team at IBM has offered to store these new results for us for a few weeks. Due to the disk space issues involved in storing these results for us, we will have to temporarily decrease the number of FightAIDS@Home calculations that are performed on the WCG. For the next few weeks, we will be crunching around 20% of the number of jobs that normally run on the FightAIDS@Home section of the WCG.

Please be patient and wish us luck during this server re-build and data recovery process. In a few weeks we should be back to normal. We'll let you know when everything has been fixed.

Best wishes,
Dr. Alex L. Perryman

Yes, good luck in fixing firstly your hardware and secondly in restoring all the data that was stored on it (good job you've got backup's). Just goes to show that a 'hard disc' crash (or it's equivalent), can happen to anyone - and certainly put's into perspective the meagre amount of data that's held on a PC - albeit, just as inconvenient when they 'go'.

Re: Technical difficulties occurred............please stay tuned during this temporary slow-down

Four terabytes? That's ... not so much, actually. Home PC systems have terabyte level drives available. I'd expect the data from this to have long passed the petabyte stage.

So. How much data HAS the FightAids@Home project generated?

Thanks,
N

Quantity isn't everything. In fact, BOINC is ill-suited for projects that have exceedingly large data transfer requirements.

Buying a few terabytes of disk drives is easy and relatively cheap nowadays.
Filling them quickly with movies in high definition is probably simple and fast too.
Filling them with very small result files organized as an operational database for everyday access is certainly much more tricky and takes much more time.

Also I presume that the Hardrives that FightAids@Home need to replace are special ones or at least high-level. So they are not so cheap.
