Like we could keep Kevin down to one machine.... ;)
Matt was out today, but I'll catch him on monday. Another thing I was worrying about today was congestion on the LAN. I'm wordering if this has something to do with kryten's problems and other occasional NFS problems we have. Since we were almost entirely Sun with 100-BaseTX when we build the closet, we're using 100 Mbps switches. If we could separate the 100 Mbps from the 1 Gbps machines, it might help the problems, especially if we do some analysis to balance things out over multiple gigabit switch backplanes. Of course since we really don't have a good understanding of the problems I might be grasping at straws. Anyway, I'll bring this up on Monday at the systems meetings. Anyone got a pile of rack mount gigabit over copper switches that can handle fairly high and continuous load? I'll get Matt and Jeff's opinion before I ask for real.

Hi Dan, I think you might not be getting my emails, and I'm not getting yours for some reason. It's not even my spam filter this time. Or the lab's spam filter as far as I can tell. I sent an email to you and Pappa giving an alternate email address. If you don't see it, have Pappa forward it to you. Eric @SETIEric@qoto.org (Mastodon)

(re new server) Add a UT2004 server onto that and you guys can name it whatever you want. :-) me@rescam.org ID: 515567 · |

Well, here's another interesting tidbit pertaining to the Bankrupt Company... (In fact; since now everything is written in stone, I can now disclose the name of the Bankrupt Company. "Cyberhome".) Their Rack System is intact... I don't know if their Rack was just using hubs, or if there are any switches, but this is another thing that I can check out on Sunday when I'm in Fremont looking at the three available Servers. If there are any Switches, I will grab them from the Rack. This is the same Rack that currently holds the APC Rack Mount Backup Battery. Eric, I will call you on Sunday and I will give you a full description of the Rack. I am up and getting ready to leave for the trip North. I should be on the road in about an hour to an hour and a half. I've never installed nor dismantled anything from a Rack environment. I'm bringing my universal screwdriver set that has bits for just about every type of screw. However; if something special is needed, and I don't have the tool(s) to dismantle hubs/switches from the Rack would it be possible for Matt or you to meet me and my contact at "Cyberhome" on Sunday. (Again, only if needed/necessary... Being a weekend, I wouldn't want to upset anyone's personal plans. However; if this Rack has what you need, and if I happen not to have the right tools to dismantle/dismount the Rack Items then I would need some on sight assistance.) Once I'm on sight in Fremont on Sunday morning, we will all know more. Sincerely, TimeLord04 Have TARDIS, will travel... Come along K-9! Join Calm Chaos ID: 515721 · |

From a strictly network engineering standpoint...nobody really uses hubs as switches cost just a little more and cut down on your network collisions much better...you will likely find switches...lots and lots of switches connected to routers...very nice routers...possibly a pix firewall and some intrusion detection hardware...as for special tools most rack systems come apart with a simple screw driver and very little else. Good luck with your find.

Are you just taking out components from the rack or are you supposed to disassemble the entire rack? If the first, you shouldn't need anything more then your universal screwdriver set and maybe some pliers (those clips you put in to dynamicly allocate where the rails go can be murder on hands and fingers if you don't have the right tools to take them out.) In case you need to disassemble the entire thing, you might need some wrenches too. For the rest, most of the components from the rack will just slide out of their rails giving you easy access to disassemble the rails. I hope you have help to carry the things in that rack. Especialy the UPS. Starting from 2U mounts the weight is around and over 30 kilo's(55lbs?). 3U's around 50(90lbs?), 5U's you can count on more then a 100 kilo's. Lastly, about the HP LXR8500, mind if I ask HP in your stead if they would be willing to swap the PSU's for that thing with their US 110VAC counterparts? ID: 515785 · |

Anyone got a pile of rack mount gigabit over copper switches that can handle fairly high and continuous load? I'll get Matt and Jeff's opinion before I ask for real. There are some fairly spendy ones out there that are pretty rugged, and there are some less expensive type that I think would work. The ones that I have are big and not copper based, but they crank on fiber. Don't know if you can use fiber. Might be a wiring nightmare. ID: 515810 · |

One kilo equals 2.205 pounds. Thanks, I'll probably never get pounds, stones and gallon conversions right. Ok so thats about 60lbs minimum for a 2U UPS, 100lbs for a 3U and from 200lbs to over 350lbs for a 5U (yeah, weights can vary heavely with 5U UPS's) Good thing UPS's are "normaly" mounted at the bottom of a rack, so you can slide them out on a trolly, its both for stability of the rack and because only an idiot would lift them up to the top lol ID: 515832 · |

Are switches still needed? I'll have like 8-9 3COM, unmanaged 10/100Mbit switches coming available at the office in the next month or so as we finally finish our transfer to our new 1Gbit LAN. I'm sure I can score 3-4 of them, easy, as I'll be sharing some with my network technician and perhaps both of my bosses. Plus, if some are needed immediately, I have 2 3COM 24-port switches of the same variety sitting unused on a shelf here in my basement. I'd be happy to box them up and send them down to CA. Otherwise, in another month or so, I may just buy a 3COM / whatever brand you want 24-port gigabit switch and send it down. Better yet, I can buy it and have it drop-shipped. Actually, double good idea time: I'll buy it at my ridiculous discount through Dell and have it drop-shipped to SSL? That makes sense. No customs or anything to sweat. MMM Pappa or Eric, drop me a line with how many switches you need and if any 100Mbit hardware will suffice for some lesser-traffic hosts. I can probably get a decent discount on these: http://configure.dell.com/dellstore/config.aspx?CS=CALCA1&l=en&c=ca&s=biz&kc=6W300&oc=OCPWC2724_RBP_REL Thanks :) Computer nut, Distributed Computing freak, Jeeper and Dodge Ram driver.

To Me having a donated server named after a Team seems like someone is favoring one Team over the rest and that seems divisive, Seti is more than Seti.USA, If I had an extra Server that met their needs, I'd say name It what You wish. If seti.usa wants to donate It, then they should just do It and be done with It, As I crunch for Seti and the PC Perspective Killer Frogs(We like to have some fun), We do Not crunch for Seti.USA. And Yeah I live in the USA. Savoir-Faire is everywhere! The T1 Trust, T1 Class 4-4-4-4 #5550, America's First HST

Ladies and gentlemen, please take the discussion about anyone naming a donated server over to the Cafe. Many people have already weighed in on the subject already, myself included, in this thread to the point of over digression. I am just making a suggestion in the hopes of keeping this thread on topic. Thank you for your time and consideration... Account frozen... ID: 516580 · |

One thing we could use fairly quickly for an existing machine is four 2GB PC3200 (DDR400MHz) Registered ECC DIMMS. I'm checking out memory needs for the other machines. Sidious needs a new CPU. I'll get the details on that shortly. I have this memory in stock and ready to ship, I sent Matt an email about it, I just need a shipping address and it is yours. ID: 517030 · |

UPDATE: I delivered the P4 System to Eric and Matt; along with the APC 1400XL Rack Mount Backup Battery, and two 10/100 24 Port Switches with Gigabit Uplink on both Switches. I received a well guided tour of the SSL by Eric. The site is awesome, Eric, Matt, and everyone are awesome people with equally awesome jobs. The Server Closet, (as described by Matt on these boards), is truly tight fitting. However; every machine has a job, and each machine performs its job admirably. Unfortunately; the P4 is unable to replace Kryten, (as surmised even prior to my leaving SoCAL for NorCAL to obtain the machine), however, Eric and Matt have plans to put it to use elsewhere in the Network. The two Switches will definitely be put to good use, and the Backup Battery was greatly needed. All in all, an excellent trip for me. I was glad to be able to assist. I will continue to keep my eyes and ears open; should any further hardware become available, I will not hesitate to contact Eric or Matt. In close, Kryten is still an open ended issue. I still hope, (as do others), that the machine offered by Dr. Dan can be added to the equipment I have delivered. Power specs and modifications are still being looked into. Other priorities at Berkeley have come up within the SSL Department; and have put a hold on what Eric, Matt, et. al. can do as far as further work on the ISP issues. However; work is to move forward again by the middle of next week on the ISP and other issues. This upgrade process is not an easy endeavor, and more hardware is needed and necessary. If anyone else can add to the assistance provided by me and offered by Dr. Dan, please feel free to step up to the plate when available to do so. By working together, we can keep the SETI Project going and assist Eric, Matt, et. al. in making their jobs a little less stressful. In agreement with Dogbytes; let's stop bickering and bantering about semantics pertaining to Server names. Let Berkeley, Eric, Matt, et. al. deal with the naming scheme. Let's just get the needed and necessary hardware to them to keep this project moving forward. Thanks, everyone. Sincerely, TimeLord04 Have TARDIS, will travel... Come along K-9!

WTG TL, even though the server wasn't able to replace Kryten, I'm sure everything will be put to good use.  Calm Chaos Forum...Join Calm Chaos Now ID: 517103 · |

By working together, we can keep the SETI Project going and assist Eric, Matt, et. al. in making their jobs a little less stressful. Perhaps Pappa can post whole servers as an option for a chruncher to buy as well as post a list per server that is needed that can be built (white box) with various chrunchers buying certain parts that they can afford and/or want to buy to get the server built. I suggest Pappa handle this and create a thread and also have it posted on the Donations page. Then, if a chruncher wants to buy a part or several parts, they can send an e-mail to Pappa who would can keep a master list of what parts are still needed, and let the chruncher know if that part is still needed or not. Of course, the Donations page and the threat would be updated as parts are bought for the new server. The e-mail to Pappa to verify a part is still needed is to make sure that someone doesn't purchase a part that perhaps someone else just moments earlier had committed to buy (which obviously means the thread/donations page hadn't been updated yet.). Just my thoughts. ID: 517138 · |
