Back to hard drives, Google have just published about their findings on failures of off-the-shelf HDD's. Thanks, very interesting. Key quotes there: Our key findings are:
• Some SMART parameters (scan errors, reallocation counts, offline reallocation counts, and probational counts) have a large impact on failure probability. • Given the lack of occurrence of predictive SMART signals on a large fraction of failed drives, it is unlikely that an accurate predictive failure model can be built based on these signals alone.

Spent the day trying to get the server based upon the Intel motherboard, the anonymously donated processors and RAM up and running and hit a snag. Despite looking like it would fit in our Intel chassis, it won't without significant use of a hacksaw. And since we're not sure whether Intel gave us or loaned us that chassis, I'm not ready to start sawing. Does anyone out there have an Intel SR2300 or compatible 2U chassis (with PS)? There's a list of possible chassis here. On the plus side, we switched fully to our new ISP, which will save us several thousand dollars a month. The rest of the day I'll get the interface for putting the paypal donations into the database working. Eric @SETIEric@qoto.org (Mastodon) |

And good you can save some money on the networking, that should ease things a bit for you. :-) "I'm trying to maintain a shred of dignity in this world." - Me |

Richard Thank You, I called Eric with an option that might solve the problem from a company that parts out used servers... I also asked about the 2U or 1U issue... If this model will fit, it will sure beat the heck out of the cost of a new one... It would be about $600.00 with shipping SR2300 2U-RM 8BAY 6HS EATX 500W KSWNA Or about $600 that I do not have currently... So as My Day was spent chasing other things... Now have more to research... That will teach me to sit down and read email... Hahahaha Spent the day trying to get the server based upon the Intel motherboard, the anonymously donated processors and RAM up and running and hit a snag.

Just a note on the SR2300 chassis: I got one of those in office. In january, when I tried to get new rackmount-rails, my Intel dealer told me that this is an "end of life product" and I won´t get spare parts anymore! mic. mic. |

Batman I truly appreciate the effort (more than most users could ever guess)! The last piece of the puzzle to get "krytens" replacement built is the Server Case... Several Users have contacted me and they were put in touch with Eric.. Over the last week, we have the two brand new 2.8Ghz Xeons that fit the donated server board and what should be 12 gig of RAM... It was requested that names of those users not be divulged, to prevent things from happening in the Forums... That was over $1,700 of donations that will have No Star (other than Eric and the Seti Staff Knows, if you can find me and twist my arm I won't tell!). They do not want fame, they only want Seti to Survive! I Truly Thank Everyone that has Helped! There are many "unsung heros/heroines," they just want Seti to Survive... If enough people considered it I could risk using my PayPal for "just this"... Right now, I am stuck in the middle of my step son's $2000 car repair bill to keep him working... Otherwise I would have bought the Server Case... Regards Pappa Edited for cleanup and where You put the em phasis on the sylabos How about this hdd? Please consider a Donation to the Seti Project. |

D@mm this is funny! Or it could be for technophiles... So it something that I missed or "new" same company... You do not know how many Salvage Dealers I have Googled for... So the next part is to see what they stripped out to drop the price... It it truly nice to see someone else starting to look... I have more browser windows open and at the this point, need to buy more RAM... 1 gig of RAM and the OS is complaining that the 1.5 gig swap is is getting full... No wonder this machine has less than a 99% average doing Seti... Regards Ok Pappa I found a case, I would hope someone could buy this case, As I can't and I'd love to buy It for Seti.

D@mm this is funny! Or it could be for technophiles... Just the change from 500W power supply to 480W. For the 480W version, the best price I found was $298.74 + shipping from Excaliber in Fremont CA. But the Froogle search I was using turned up several others in the low $3xx range. Overall wattage ratings on power supplies for consumer systems are often very misleading. I guess Eric would need to decide whether the 480W power supply is enough for the intended configuration.

With consumer PSU's the watage is usualy the overal rating on all rails. This is problematic because, in some cases you need a strong 5V rail and in most cases you need a strong 12V rail, the later is usualy the lacking one. Whats different between general desktop PSU's and server/overclocking PSU's is that in the later there are several 12V rails and sometimes even multiple 5V rails, to help with stability. That way you can spread load over the rails better or put certain hardware, which is sensitive to voltage fluctuations, on its own rail. With general desktop PSU's, you usualy get stuck with 1 rail, so if you have 1 device sucking the voltage down to 11V other hardware will be hurting, badly (disks can even randomly corrupt). |

Morning Everyone One of the drive types that are needed to get Storage up to snuff for the UpComing transfer of Multibeam Workunits is: 73GB 10K U160 80P 16MB ST373405LCV yes these are becoming obsolete and harder to find... We need 8 of them! IF you can afford one of these and want to ship directly to UCB, then please conctact me... I can give You the shipping address. al.setiboinc (at) gmail.com Please consider a Donation to the Seti Project. |

Morning Everyone Why are we currently setting up a system for the Multibeam Workunits that uses drives types that are obsolete and hard to find now? What happens in 5 years and we now need drives that cannot be had for any price? What then?? Boinc....Boinc....Boinc....Boinc.... |

It is not that is bad hardware, just that hard drives die... "When that is all you have to work with," it is all you have...

It is not that is bad hardware, just that hard drives die... If I may say so, I think the geek deserves a more responsive answer than that. A brief Search reveals that there are lots of *much* more expensive 73GB SCSI drives available. There are also lots available for about half the price, but they tend to have about a millisecond longer average seek time. I can make up reasons why this particular drive is specified, but I do not *know* why. Why 73GB? Why 8? Does that include some as spares? Does SETI@home already have lots of these drives? This is by no means a hostile response. I would really like to have a bit of "my" hardware contributing to our work and will buy one for you if you can provide sensible answers to good questions. |
