What do the Transitioners do? Or rather what are they not doing? How significant is 19 backlog hours?

Backlogs are like warm, familiar comfortors on a cold winter night. We enjoy them and embrace them while wishing we could put them away for the rest of the season.

With all the different HDD failures, it would be interesting to see some stats (by brand) of the different drives S@H uses and their MTBF numbers.

Matt has posted somewhere that they have some pretty strong views and strict buying policies, not least because of compatibility problems in the past with their motley collection of motherboards. I'll try and find the reference. In the meantime, for anyone thinking of helping out (as in another adjacent thread) - it would probably be best to wait until an exact specification (ideally, model number) has been posted, or just send earmarked cash. Given that practically everything is in some sort of RAID array, disk matching could be important.

Yeah it would be interesting for sure to see those numbers. Something tells me they aren't using Maxtors, Hitachi, or Samsung drives. ;)

I believe my brain noodles are thinking Matt said they use Seagates, and preferably at least 750gb. SATA-II. I do not recall reading whether they are the Barracuda XT's or not. Also, the noodles are remembering that this specification is for the drives that transport the raw data from the telescope to the lab. I would imagine they probably try to use Seagate in all the servers, as well.

Seagates run really hot if they don't have good ventilation. Hitachis are much more reliable when it comes to their firmware. (Did you know Western Digital is just Hitachi drives rebranded?)

Yeah, looks like there's a few missing styles or stylesheet(s). Did they perform some kind of upgrade, or perhaps the web server crashed? No news yet.

Hope there's no file corruption causing this.

It'll be because someone's been applying some new changesets, like this one: [trac]changeset:23008[/trac]

you can tell it's been applied here because the following has changed here:

Suspend work when non-BOINC CPU usage is above
0 means no restriction

...

From a newer post by Matt, for transport they're now using 2 TB drives.

Thumper and Bambi have many 500 GB drives, and Sun was supporting those (but may no longer be doing so after becoming part of Oracle?).

Oscar and Carolyn have 1 TB 3 Gb/sec SATA drives, under HP warranty. They're running with 2 root drives, 2 hot spares, and 8 drives in RAID.

Synergy has "5 Seagate Constellation 1TB 6Gb/SAS Hard Drives 7200 RPM".

Replacement drives for the Snap storage server donated by Overland Storage are provided as needed.

I don't know about Gowron, the name suggests it is at least a couple of years old. ISTR mention of the staff building up a storage server from donated components about then, probably would have been 1 TB 3 Gb/s Seagate drives if so.

The original Bruno had a fibre channel array and probably somewhat smaller drives. I'm not sure if the Bruno Back (Feb 01 2011) thread refers to that or Bambi renamed to Bruno.

All in all, I agree with Richard that waiting until Pappa gets more information makes obvious sense for those considering hardware donations. Cash donations of course are always needed, and can be earmarked for drives if you prefer. My own take is that I hope there will be enough unearmarked donations so neither Matt nor Jeff get a pink slip.

We're screwed. Nothing can save us now :-)

Agreed! The real question is did we want anything to actually save us? (:

Have a look at the AQUA message boards. There's been a recent 'new look' there, including (for the first time) icons alongside threads you've already read.

I think what we see here is a planned (but incomplete) style makeover.

Probably cause of the mass pounding the servers are probably getting, cricket is probably maxed, haven't checked. No problem though, got 1 WU that was stuck trying to download for a few days thats now crunching. :-)

Exactly, out of work, since a very long time, though, but now, not a single SETI MB or AP, yeah in DownLoad, but doesn't come through. HTTP:ERROR.

But made good use of this possebillty, to install the ATI MB & AP app,
from LUNATICs.
And on the Number Crunching Forum.
Vacuum the X9650 CPU COOLER, (well it's a rig Whitout a Case, so a lot of dust, no cooling troubles, f.i. a 850 Watt PSU, doesn't even get 35C, loaded @ 550Watt. Cards run run @ <50% FAN, little noice.

IMO, most PC Cases, latests and 'Gaming' rigs, already have their case adjusted.
Many PSU have died, cause of the (multiple)GPU's and (OC'ed) CPU's.

Yeah, upload and download works. I guess we're going to clear out the limbo-ed transfers before turning the scheduler back on and getting new work assignments. I know some people have had a stuck download since the weekend (I know I had one).
