What To Do With a Hundred Hard Drives?

Makoto916 writes "In five years with my current employer as the IT administrator, I've amassed a sizable cabinet of discarded hard drives; just shy of 100, in fact. All of the drives range in size from 20GB up to 300GB. They've all been stored in anti-stat bags, and spot checks of even the oldest ones show that most of them still work. Individually, they're mostly useless for our line of work, which is digital video production. However, the collective storage potential is quite significant. They are of varying size and speed, but the one commonality is they're all IDE. What is the best way to approach connecting all of these devices and realizing their storage potential? On a budget, of course. Now, I'd never use such an array for critical data storage, but it certainly would be useful as a massive backup array to our existing SAN that does store critical data. I have several spare and functioning PCs, but not nearly enough to utilize their internal IDE controllers; even with multiple add-in controllers, it still wouldn't be enough. Not to mention the nightmare of managing a bunch of independent PCs. I've looked into ATA Over Ethernet and there's a lot of potential there, but current 15 to 20 bay AoE cabinets are expensive, and single device enclosures are so rare that they're also expensive. Are there any hardware hackers out there who have crafted their own home-brew AoE systems? Could they scale to 100 drives? Is there a better way?"

      This is always a good idea. Move the swap and the Windows temp to this drive and keep it formatted FAT32 (or lower). If you can, partition the disk up and give it two 2 gig partitions. Each partition should be formatted FAT16 (aka: FAT, no 32). FAT32 and FAT16 need to read/write to the disk less for each transaction than NTFS and is much faster for it. Since it's just swap and temp files, you don't need NTFS.

      If you do this, you leave the rest of the drive open for users' personal files or whatever. The two partition setup should be one for swapfiles, the other for temp files. You can get more creative and create another for a web browser cache, but as you create partitions the drive head has to move farther to span the space and slows down the operation. A large FAT32 partition works well if you dig deep and move a lot off onto this second drive. Another thing to keep in mind is what people are going to be putting into their temp directory. Video work might create files bigger than the partition. In this case, create a 2 gig swap partition at FAT16 and leave the rest FAT32 for normal files.

      I always get a second drive now for this reason. Helps in both Windows and Linux. For even better results, keep the drives on different IDE channels. Just think, the overall strategy is to keep one disk working on program data and the other working on the memory swap data - a major bottleneck, especially at IDE speeds.

  18. How About Just a Dozen? by Doc+Ruby · · Score: 4, Informative

    I got a $20 enclosure with 17 drive bays in it, and a 300W power supply. I've got a dozen SATA drives, each drawing under 10W, and 5 EIDE, drawing under 20W each.

    At first I just got a dozen SATA/EIDE USB slaves for $10 each, and plugged them all into a USB hub, with just the single USB cable stretching out of the case over to another full PC's USB socket. But that is so slow, especially when copying big music or video files between drives (and through the single USB cable to the CPU and back). Playing multiple media files to different terminals in my house is too much bandwidth for the single USB, too. Running 4 USB from the big enclosure to the 4 sockets in the server PC isn't much better, because it all goes through the same CPU and PCI bus.

    So I got 3 Sabrent SBT-SRD4 4xSATA controller PCI cards, because they were $25 each. But when I tried to boot them in a few different motherboards (pre-HP Compaq P3/1.2GHz, IBM P4/3.2GHz), none of them got past the POST to even start booting the OS. I want to use them with Linux, but with the failure to even boot I'm not hopeful about driver support, either.

    I bought them from CompUSA (still alive, online only), which hasn't replied to (email only - no phone available) tech support requests. Nor has Sabrent itself. I'm not hopeful that they'll refund my money, since everything else about this transaction has sucked.

    So what I want to know is what cheap motherboard (no need for graphics or anything else other than at least 3 PCI slots and 100Mb-1Gb ethernet) will work with these SATA cards? If they're really duds, what is the cheapest way to get 12 SATA drives controlled, even if they're not that fast, over to 100Mb/Gb ethernet? Either SATA cards + motherboard, or even a fat mobo with a dozen SATA ports. I'd even settle for just 4-8 SATA ports to get started. I'm talking under $200 if possible.

    Ideas? If it works, then 8-9 of them should support the 100 HDs the original question was asking about.

There is a natural temptation to look at magnetism the same as electricity (individual charges, like electrons and protons, being analogous to "North" and "South" monopoles), but probably the most useful way to think of magnetism is as a relativistic effect of electrostatics... once you do that, there's no reason to assume any kind of magnetic monopole at all.

If you think about the above equation, it states that the total magnetic field through a closed surface is a net balance. In the world as we know it this is a correct equation. But if monopoles exist the zero would be replaced by a variable (say m for the imbalance in magnetic particles). This is similar to del * D = p describing the electric charge within a volume but with a calculation for the magnetic field. But since the known universe

    Not just for the simple software raid and all that, but for the automatic block checksumming, something I would be concerned about with a big pile of really old drives.

    1 kW may not be enough to keep you warm during winter, but it may help you survive if every other heat source fails.

  53. Get a real backup solution by Arethan · · Score: 3, Informative

    Disk based backup solutions are worth the effort, so I can see why you're leaning this way. Unfortunately, trying to utilize ~100 PATA drives for this is going to give you nightmares for ages. Find a way to reclimate them for cash, either directly or indirectly. Hell, you can donate them to charity for a tax writeoff if you like (just make sure you DoD wipe the disks first). Take the reclimated capital and buy yourself a new data-deduplicated VTL, or a NearStor, or similar. Backup solutions need to have some level of trustworthiness to be useful, and I doubt you'll find that in a pile of aged PATA disk.

  54. DoD now specifies to degause or slag drives by Anonymous Coward · · Score: 5, Informative

    If you use the software approved by the DoD for 'cleaning' you should be safe. First off, the DoD is no longer responsible for writing the standards, NIST is. Their document that covers this is NIST 800-88.

    The standards for data sanitization is more stringent now. Anything that is more sensitive than Classified, and leaves the control of the organization disposing of the drives, needs to be either put through a degauser, chopped up into tiny pieces, or turned into slag. If the media is simply going to be re-used with-in the organization then wiping is okay.

  55. Re:Not worth the trouble by mlts · · Score: 3, Informative

    SAN drives are also generally smaller in capacity, around the 250 GB range, and a 2.5" form factor. The reason for this is to maximize the spindle count. For example, having five 250GB drives with RAID 5, each running at 10,000 RPM can handle a lot more I/O (especially random seeks) than one 1TB 3.5" SATA drive. SAN drives also have a lot more cache. The reason that a most SAN companies have moved to 2.5" for their drives is because even though the platters have less capacity, the data is faster to get to on a physical basis, and case engineers have more room to engineer around the drives, especially in 1U rack enclosures than 3.5" drives.

    Enterprise drives are definitely more expensive, but in this case, one gets what they pay for -- a lot more speed (especially with large, random seeks), and decent redundancy. The drives themselves are in the million to 1.4 million hour MTBF range, while consumer level drives, either don't have a rating, or the MTBF is hard to find, so the best guess is 250,000 to 500,000 hours, although some drives do have a million hour MTBF.

    The key is to figure out the task at hand, and one's budget, and decide that way. Some tasks, just hooking up drives to the motherboard and using software RAID is more than workable. Other tasks are so time dependent that one has to have full hardware RAID with as many low-capacity spindles as possible to distribute the I/O far and wide. This is why Flash drives are making a good dent in the enterprise RAID market -- they are not perfect, but there is zero time wasted waiting for the head to move, and the right sector to float by.

  56. Use them to keep your users in line by Kwesadilo · · Score: 2, Funny

    Fill them with contraband media of various types and give them out to your users (and lusers). You could systematize it. If someone goes six months without "breaking" their computer by changing the settings, not liking it, and forgetting how to change them back, that person might get a 4-gig full of random music that you pulled off of Gnutella (or whatever). If a user goes a year without unintentionally creating a security risk, he gets 50 GB of unsorted porn. For the god of a man who has gone his entire career without a trouble ticket and is miraculously using ten-year-old hardware with no failures, you could have a 300 GB drive with all of the best video games, modern and classic.

    And for the jackass who wants a new monitor because he changed the display resolution, tries out script-kiddie hacking tutorials on his coworkers, constantly demands faster equipment for him to do nothing with, looks at thumb drives he found in the parking lot, and gives up his password for a candy bar, you could stealthily replace his hard drive with a very small one containing Windows ME.

  57. That magnet prank will fail by KWTm · · Score: 2, Insightful

    Make it a true geeks trick. Put the magnets on the inside of the fender spelling out "Very Small Penis". Then shake some iron filings over it. It'll keep trying to reform the words as he wipes it off and each day when you walk by it just sprinkle some more filings over the spot to keep the joke going. See how long it takes him to figure out they are on the inside
    It seems to me, intuitively, that this will not work due to the ferromagnetism of the fender, which is presumably metal. That very property which allows the magnets to cling to the inside of the fender will also capture most of the magnetic field lines, meaning that it won't attract the iron filings (or will attract them evenly, so that they don't spell out any words).

    For the words to appear, the material separating the magnets from the iron filings would have to be unaffected by magnets; for example, if you put the magnets under a sheet of plastic or wood, then the iron filings will clump according to the placement of the magnets. On the other hand, if the fender is made of plastic, the magnets won't stick to it in the first place.

    That's just my intuition; can anyone correct me on this?
