    Show Your LCD(s) setups!!!

    Woot! Props for the Accelear 1200 in the bottom of your rack... 15 million packets per second baby.... I have several of those banging around the office. They are so noisy we quit even using those for lab gear.... those were great products in the day....

    Ghost/clone a linux hard drive

    Tru dat spacehonkey. I will be a bit more verbose. DD is a block byte copy utility. If your drives are identical, you can simply duplicate the primary at the byte level. Lets say your boot disk is /dev/sda. Your boot disk won't be /dev/sda1. The "1" indicates a partition on the disk. You...

    Just ordered the Dell UltraSharp 2209WA

    I'm jumping in late on this. I have the Spyder 2 express and the software stinks. I have installed a demo copy of the Spyder 2 Pro software (which I can't buy anymore) and it bombs trying to calibrate my display. Either way it's kinda schlocky software. I haven't used the Eye-One Display 2...

    HDD wiping before selling as used?

    You can overwrite with semi-random data under linux: dd if=/dev/urandom of=/dev/hda bs=1024k Or zero: dd if=/dev/zero of=/dev/hda bs=1024k You have to be certain that /dev/hda is your disk. If its sata it would be something like /dev/sda or something... you can use dmesg to check...

    OK, Let's have some educated opinions on RAID0 stripe sizes...

    It really doesn't make that much difference for an application mix if you are writing page aligned blocks. I believe windows PCs use 4k blocks for RAM paging so as long as it's a multiple of 4k it probably doesn't matter much if you don't have a very specific application. Now if you have a...

    Questions About Raid-5

    If you run windows, a raid card will be most stable. If you run linux its a toss up. You can get better performance with software RAID under linux than a lot of hardware solutions (especially in a non-enterprise level). You do have to worry about data corruption during power failures with...

    Anyone use a via nas 7800 for a file server?

    Its probably going to be several hundred dollars... an underclocked previous generation PC is going to be a lot cheaper. Other than that, it's a hot setup.

    CF card as HDD?

    IF you insist on doing this on linux you can set the mount option "noatime" and it will reduce the excessive writes by not updating the access time on files... I would try and keep the "highly variable" disk areas like /var on spinning disk and I would run a ram disk for temp...... I have...

    linux raid server

    I have done a similar thing, but I was using raid 1 pairs due to the time/size differences between my drive purchases (2 x 40, 2 x 80, 2 x 160). You can configure the cf card as /boot and use the mount option "noatime" in the /etc/fstab to prevent the OS from updating the access times on files...

    Seeking advice on RAID setup for my shiny new Linux server

    As another Linux user, I would recommend looking at something besides ext3. I have had numerous clients have the jornal blow out (recoverable, but a pain as you have to overwrite the journal, fsck it as ext2, then rebuild the journal and re-mount as ext3) and I have had a few that have...

    CF card as HDD?

    Slow and dangerous. If you have things that write to the disk a lot, you can prematurely wear out the disk. Of course you can fix these things by turning off virtual memory etc, but as the above poster indicated it's not a great idea. The one place it is good is for thin embeded systems and...

    5 in 3 SATA Backplanes, anyone use them?

    I have two of these things in an old Enlight server case: http://www.newegg.com/Product/Product.aspx?Item=N82E16817990004 When I got these, Frys had them for <$100 each in store (They also had WD10EACS 1TB OEM drives for cheap at the time). If you rate the build quality of a HP/Compaq OEM...

    Rate my under $500 fileserver

    My $0.2 from some experience with my home-brew servers: 1. Awesome deal on the beer to hardware conversion, 2. On your PSU, the thing you need to watch out for is the +12 volt rail. Depending on the vintage of the PSU and several other factors you may be fine, you may not be fine. Just...

    Recommend PCI/PCI-E RAID card for Sata2

    I have used the hotpoint card in a VERY small server which was basically a windows share for a point of sale application and for what was needed in this application (data integrity and reasonable file access speed under WinXP) it was fine. It gets you no-nonsense bootability for a RAID 1 setup...

    Linux file server problem - Slow samba transfers on gigabit

    A few things, I can attest that the silicon image controllers cause problems. I had 3 1tb disks in a MD raid 5 under Ubuntu 7.10 and basically a few months after I built the array a power outage caused the array to go out of sync and I could never complete a rebuild. I would get a kernel pannic...
