Just a daft question. "The 10Gbit switch will become part of a very high speed SETI spectrometer to be deployed at the Greenbank Telescope." I assume that this helps SETI@Home in some way? Because there is no explanation as to what this does. It's part of a highly advanced SERENDIP system we've been working on for implementation at the Greenbank Telescope. For a bit on how it works, see (source for the below quotes) https://casper.berkeley.edu/wiki/SETI_Spectrometer#Data_Recorder The condensed version: The spectrometer uses a polyphase filter bank (PFB) to implement a bank of steep cut-off bandpass filters, providing a significant improvement in signal-to-noise and out-of-band-rejection over the common FFT algorithm. The PFB uses a biplex pipelined architecture which allows data to be input and output at the full sample rate, and can do two polarizations simultaneously with no extra cost in hardware or data flow rate. The above is in addition to applications in SETI, FX correlators, pulsar, and general radio astronomy. In even briefer summary: more science, faster, with less noise. SETI will also have a data recorder attached for S&H applications per my understanding, though I couldn't tell you for certain without seeing more specs than I have. We've been working on smaller parts of the pie which is probably for the best. ____________ Executive Director GPU Users Group Inc. - brad@gpuug.org | |

Unfortunately we haven't garnered any new donations today for drives so far. If you'd like to help us take advantage of Newegg's sale on these drives (and thusly save the project around $1200), please visit the links below | |

Just bought another 5 drives. That should at least get us past the 12 that Eric needed for the Hydrogen survey. Slavic can you give us an update of how many drives we're up to when you get a moment. Thanks. | |

Thanks. Will do just as soon as the last RMA comes through (should be Tuesday). Thank you Mark, you're amazing! ____________ Executive Director GPU Users Group Inc. - brad@gpuug.org | |

Just bought another 5 drives. That should at least get us past the 12 that Eric needed for the Hydrogen survey. Slavic can you give us an update of how many drives we're up to when you get a moment. Thanks. Okay here's where we are with the project currently: 1. Total needed $4800. Raised $2390 which equates to just shy of 20 drives which is excellent. 2. Here's what Eric wrote about what we'll be doing with these drives: - The distribution will be closer to 50-50 between SETI drives and Hydrogen drives after some retooling. - All drives will be in one machine. - We will start with 25TB available for hydrogen and 43TB available for SETI online data/backup. - This will probably end up at 36TB for Hydrogen and 32TB for SETI. - If this storage system works out well we'll be replacing the labs current system which is currently costing $200/mo/TB for SETI storage and is rarely used due to the high cost. - Additionally if our plan pans out we'll end up likely populating another 24 drive enclosure with 2TB drives which will significantly improve our storage capabilities while at the same time significantly reducing overhead costs, freeing up funds for other improvements in other areas. 3. All we're waiting on right now is for the last RMA to be finalized on Tuesday then we'll purchase however many drives we have funds for them which will let Eric get the ball rolling on his project. __________________________________________________________________ If you'd like to donate a drive directly please visit http://www.gpuug.org/content/cash-4-drive-hitachi-gst-deskstar-7k3000-hds723020bla642-2tb Or if you'd like to donate to the general pool please visit: http://www.gpuug.org/content/setihome-hydrogen-survey-seti-storage-array-hard-drives ____________ Executive Director GPU Users Group Inc. - brad@gpuug.org | |

Quick bit of good news: | |

News update for everyone courtesy of Matt and Dan: Both georgem and paddym have been working great, though georgem had been blocked up a bit as we were using it as a temporary storage for Kepler data. A large chunk of that finally finished copying off yesterday so I was able reclaim some space/functionality. The rest of the Kepler data should be off in a couple days. Anyway, they are still pretty much georgem: workunit storage, compute server, and file server and paddym: master science database. I'm not sure if we can add more functionality to paddym as the science database is pretty much a full time job, but georgem still might adopt various BOINC server functionality over time (upload server, download server, scheduling server, internal BOINC back-end server...). ________________________________________________________________________ If you'd like to donate a drive directly please visit http://www.gpuug.org/content/cash-4-drive-hitachi-gst-deskstar-7k3000-hds723020bla642-2tb Or if you'd like to donate to the general pool please visit: http://www.gpuug.org/content/setihome-hydrogen-survey-seti-storage-array-hard-drives ____________ Executive Director GPU Users Group Inc. - brad@gpuug.org | |

I think that you have to do some work on your donation tracking pages so that they reflect the actual status of the projects. | |

I think that you have to do some work on your donation tracking pages so that they reflect the actual status of the projects. I've updated the donation total tracker this morning. We're at $1860 to go total on the hydrogen/SETI storage drive fundraiser. The cash-4-hardware link in my post above works. You can donate a drive directly by visiting http://www.gpuug.org/content/cash-4-drive-hitachi-gst-deskstar-7k3000-hds723020bla642-2tb or you can see all of our hardware donation projects by visiting http://www.gpuug.org/donatehardware. Sorry for not keeping up with the tracker. Should be good to go now :) ____________ Executive Director GPU Users Group Inc. - brad@gpuug.org | |

Quick question, I clicked on the Newegg link to the drives, and thought I would take a look at how they are doing in the real world. It listed the reviews from newest to oldest, and I was shocked at what I saw. Of the 1st 20 or so that I read, (till around 6/1/12) all I kept seeing was dead, dying, arrived destroyed, lasted only hours/days/weeks, etc. If you haven't opened or installed them yet, you may want to do a little more checking into these, maybe to spend a little more $ and get a (hopefully) higher quality more enterprise level drive? The main reason I'm suggesting this is that we have had our share of HW issues over the years, and it seems that we may be setting ourselves up for more self inflicted heartburn due to drive failures. I know that more people write to complain than compliment, but the product reviews are a good way to get at least an idea of what is currently happening with a product. Please check it out and see what you guys think. I'm all for donating, I have in the past and plan to again in the future. I just want the money to be used wisely, and sometimes the best priced isn't the best value. | |

One other that looked like it might fit the bill, if your enclosure could handle it, was a ST32000645SS Constellation 2TB SAS ES.2 6GB S 7200RPM 64M 3.5 Bare drive. Provantage has a better deal on them, and the interface is much more enterprise level. :) http://www.provantage.com/seagate-st32000645ss~7SEGS2CV.htm Just a thought, and they are the same price! | |

We were given a specific set of specs for this project (make, manuf, specs). If it had been my choice we would've gone with a different drive, but then again even the previously rock solid Seagates are giving us major issues. | |

Very true, and hopefully they'll run some sort of validation utility on each of them before creating the array. The best part is that it is an array, so unless a number of them go down at nearly the same time, there should be time for the replacement. I was reading that there was a little bit of a time lag to get the replacement via the warranty (I think I read 2 weeks was the turnaround for one unlucky purchaser), so they may want to try configuring one or 2 of them as hot spares, and maybe even set the goal to 41 drives, so you can have one on the shelf to throw in at a moments notice, just in case. I'm really curious to know how they all play out, from reading the discouraging reviews. Can you ask the team if they could keep track of the issues these drives present? It may help the rest of us out here in making HD purchasing decisions depending on their experiences. Thanks much, keep up the good work! Go Team Green Stars! ;-) | |

I assume that this helps SETI@Home in some way? Because there is no explanation as to what this does. Explanation... must-read. New 'scope, new receiver, new project coming online in about 5 months as part of SETI@Home. I'm raising funds for it in the other pinned thread. Edit: Didn't see this thread had a second page. :^) It's been answered already. ____________ “Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it's the only thing that ever has.” --- Margaret Mead | |
