    Reasonable PC (cheap, std): $500 SCSI controller: $50 10 100 GB hard drives (IDE, see pricewatch): $2500 Alcita IDEPlex 2 board (scsi IDE): $600 Chassis for disks: $100 Total is $3750, holds a terabyte. Put Linux on the box so it will serve SMB and NFS and you have it. An IDEplex will let you hang 8 IDE busses on a single SCSI ID, so you can hang up to 56 IDE drives on a narrow SCSI bus with one of them. That would allow you to expand to 5.6 terabytes using 100GB IDE disks even on a narrow SCSI bus.

    But for those wanting to build a 1 TB servers, cheaper options already exist with commodity components. For example:

    18(*) WD 60 GB hard drives ($2250)
    3 Hotrod ATA/100 controllers ($180)
    Powered enclosure ($200)
    Custom extra-long IDE cables ($150)

    Get a motherboard with 4 IDE channels (most "raid versions" have this) and plug 12 drives into the Hotrods, 4 into the motherboard's raid channels, and 2 into the secondary ide channel. The boot hard drive goes on the primary ide channel.

    The total cost of this server is still under $3500 after supplying the rest of the computer. As long as you don't need 24/7 uptime or massive throughput, this is enough for 1 TB of directly available storage.

    (*) This is a bit more than 1 TB but you have to account for space lost during formatting.
  • The space is an anti-lamer measure. Slashdot will put spaces in ANY long text string to break it up. Back when Slashdot was still new some lamers discovered that they could make a string 10000 characters long and force the "width" of the Slashdot window out forever. It was extremly annoying because you had to constanty scroll left and right to read the real posts in the article. These days you can't do that anymore, but you have to deal with spaces in links if the poster doesn't know how to make them real links (Hint, look up the Anchor tag, particularly the HREF option).

    Down that path lies madness. On the other hand, the road to hell is paved with melting snowballs.

    There are plenty of uses. I work in a radiology department where all our images are acquired digitally instead of on film. We acquire an estimated 4-5 TB worth of images each year. Our current archives (optical disk) will only hold about 1 months worth of data online before patient images get taken offline and put on a shelf. The ability to have a cheap TB online archive would mean significantly faster image retrievals when radiologists want to compare a patient's images with a previous study. Especially important when hospitals are cutting budgets back in a big way, but workloads keep going up.
  • How manny of those "Hotrod" controlers can you put in a a single motherboard? I ask because It looks like a Cool idea to have the controlers do hardwear raid and present the OS with a single drive 180GB or 300GB drive each. (Using 60GB or 100GB drives).

    The OS could then be asked to make a software RAID of those. I.e. with 5 controlers you could have 1.2 TB at a sane cost.

    Perhaps not under $5,000 but still sane.

  • If you aren't using Gigabit, how in the hell are you getting 20-25MB/sec reads? Last time I checked, Fast Ethernet maxed out at ~10MB/sec.

    I was just going to ask the same thing. Maybe he meant that the system itself was able to access the disks at 25 MB/sec?

  • At $5,000, I'd imagine just building a second one makes the most sense. Unless you want to drop $80,000 for the hardware and software to put all that data on tape. :-)
  • $3242.50 as of this morning. Still too close for comfort. :)
  • RAID-5 in hardware kills you, unless you go to very very expensive hardware. Expensive as in more than $5k for the RAID controller alone.
  • Well any company that can afford that kind of storage and the software associated (11TBs plus the mirroring software would be 6mil easy) should also have someone smart enough in the architecture department who would understand do fiber multiplexing off to yet another box of disks for your hotbackup. Obviously they wanted a hotbackup if they needed disk backups and the mirroring wasn't enough.

    DLT would of course choke a horrid death on this. Although I have seen some pretty interesting DLT setups. The best was using another 4 port 100baseT card off a sun with each port doing a specific set of mount points to a DLT with 4 drives. That thing could backup a ton of data in one evening.
  • Ok, but they forgot to buy their backup system. A big server's no good if you can't get your information back after a catastrophe (e.g. is it sitting under a sprinkler head?).

    Good grief, what do you back up a terabyte onto these days?

  • Sweet, finally enough disk space so I can compile mozilla staticly with optimizations!
  • I am in the process of building a fileserver for my little visual effects company. This article was extremely helpful and informative, although my solutions will be somewhat different from theirs.

    In particular, they claim to get 50 MB/sec transfer rates from their disk array. But, you can see that they also specify just a 10 MB/sec 100BaseTX ethernet; so 80% of that bandwidth is completely wasted.

    I was curious what people's solutions to this are. Does one just get multiple 100BaseTX ethernet connections to a switch, or are people going Gigabit ethernet from the fileserver to the switch?

    I plan to go the second route. There are many ethernet switches out there with one or two gigabit ports such as this 3COM switch [3com.com]. This should give 100MB/sec to the switch, and then the switch can distribute this bandwidth to all the client machines at 10MB/sec.

    At least this is a reasonable stopgap until Gigabit Ethernet is more ubiquitous.

    Any comments?

  • Commodity disk is $3 / gigabyte.
    A quarter of that in 2003.
  • Offsite mirroring? Most of the big storage systems like EMC or Xiotech can be mirrored to another unit somewhere else, and most can do hot copies of existing data sets, which can then be dump to tape at some drone's leisure.

    It's not an inexpensive solution, and it presumes you have a facility someplace offsite to mirror to. Storing 1TB is easy, managing 1TB isn't.
  • For the time/space functionality of offsites, why not just have three storage units: primary, offsite mirror, and the backup/copy one. When the backup/copy is done, pull out the disks. Send them to the vault, and insert another set of disks.

    We've been looking at re-doing our storage, and the ability to do backups transparently to disk is quite compelling.
  • I helped build one of these a few months ago. It had 16 of those 80 gig maxtors. The worst part is getting all those cables arranged... what a headache. Now i'm posting this message on another one I didn't build but is very similar.

  • The NetApp Filler's NFS does NOT work flawlessly, at least not with AIX. I had one in on a demo, and it works fine writing with many small files, but as you increase file size, there is a problem that pops up. I had the same problem using Linux as an NFS file server for AIX.

    As you increase file size the filler takes longer and longer to return write acks. The more ram cache you have on the filler, the worse it gets. The exact symptoms have under linux, but on linux I can get to a command propmt, and type 'sync'. As soon the prompt returns, AIX is off and running again. This does not happen if I use Solaris. I did not have the time to try any xBSDs. NetApp was confused, IBM was confused.

    After careful consideration, I have determined that every terabyte of data you want to backup will cost roughly $5,000.

    Even if you don't do incremental backups, it's still a bargain. Hell, get some more of these teraservers and do software RAID between them; this is phenomenally cheap space, folks. For the price that companies are paying for this kind of space currently, you could buy tens of terabytes of space and make it octuple-redundant and still knock a heap of cash off of your capital budget.

    Tar up your terabyte, copy it across the Internet (or a private circuit, if you're really smart) to your off-site spare teraservers that cost $5k a piece. That's still an order of magnitude more cost-effective than shelling out the dough for Digital's disaster-tolerant FDDI remote clustering technology.

    The bandwidth costs are irrelevant since they apply to any backup/clustering technology, and it's quite obvious that it's cheaper to buy lots of $5k terabytes and spread 'em out across the country than any of the big guys' "commercial enterprise-class solutions."

    When in doubt, have your company buy 10 more terabytes just to be on the safe side. It's only $50k! Most manager-level positions at Fortune 500s can sign off on a purchase that size.

    This stuff is great! Give terabytes as stocking-stuffers to your kids at Christmas.

    1 Tb for $5000 is nice. Size is one thing, but the underlying software is another thing.
    Netapp filers are expensive, but excellent because the filesystem (designed by former SGI employees, who designed XFS) rocks. It's fast, it's damn reliable, and the "snapshot" feature kicks ass. Also, their NFS implementation works flawlessly (and this is a *rare* thing) .
    So SDSC has a nice project on the hardware part, but I wouldn't trust them for production servers.

    Wayne: "Yes, Apple's stuff is too proprietary. MS is the open alternative."

    Both: "MS rules. Apple sucks. MS rules. Apple sucks."

  • Actually, yes, sometimes a budget server with massive disk space is just what one needs. I currently maintain a mirror site (various flavors of Linux, BSD, etc...). We can't really afford to utilize our most powerful server for this task (though it isn't too shabby of a box) but have equipped it with a 3Ware IDE RAID controller and 240-gigs of data space (it has a 9-gig scsi boot disk). (FWIW, one of the 2 120-gig RAIDs just ran out of space last night; going to move to an 8-port 3Ware =)

    Anyway, my point is that the data is totally expendable. All of it can be restored simply by running the same scripts that keep the data updated with rsync.

  • I always thought it was $3,000...
  • I put together one of these babies (2/3 TB, $2500)a few months ago! 3ware is cool. They had a bug in their RAID 5 code, but the support/handling of the issue was exemplary.

    We put 8 80 GB maxtors and an Escalade 6800 in an old Gateway P166 tower with 32 MB, an extra power supply, 3 extra fans, and 2 NICs, running Linux 2.4 kernel running recent NFS code.

    The only trouble was when I tried to format the drives with Partition Magic; it couldn't handle the size and corrupted my partition table! It's now running great. A drive died once, but came back online; the rebuild ran flawlessly. PS whoever posted about using PowerFile should have checked the prices first.

    I have a hard copy of http://www.raidzone.com [raidzone.com] taped to the side of the box.

    It's used to send and retrieve large files over the 'net; I haven't even bothered to benchmark it, as the 'net will be the bottleneck.

  • Oh, and one more thing...because you are working with optical media you have a far less likely chance of data failure than with a bunch of expensive hard drives. Really all you have to worry about is fire and you can easily make a complete backup of the entire system by just buying another spindle of CDs/DVDs and a nice standalone burner.

    What I would use this system for is creating a single media center for my entire family. Everyone would give me their records/tapes/CDs, I would convert them to MP3s and burn them to the collection. They would give me their video tapes/DVDs, I would encode them as DivX or something and burn them to the collection

    Then any time they wanted to watch or listen to any record, tape, CD, video, or DVD it would be as close as the nearest computers (or entertainment center by making a nice TV-out PC). The originals could all go into storage in a nice, safe, dry place.

  • Well, if you took your own thumb out of your ass and used it to thumb through a CD burner manual you would find that any modern CD-R/RW drive can record data instantly in UDF packet format. So to the users it would look just like a normal hard drive. Since DVD-R/RW/RAM uses UDF by default this is even easier.

    Not to mention, the intent was to migrate an entire collection of data that would be offline storage to online storage without wasting hard drive space. If the data is a bunch of audio or video files it is pointless to have read/write access since the data doesn't change. If you need to "delete" it you can take the CD/DVD out of the unit.

    - JoeShmoe
  • I said CDs OR DVDs...the carousel could mix and match any type of disc you want just like the home theater versions (you can put CDs or DVDs in your Sony SmartFile and it will play either one). And as the above posted said, there are disc formats the same size that can holds GB of information.

    But you are still wrong that there is any sort of filesize limitation. The filesize limitation is a function of the Linux thinserver, not the disc hardware. After all, any modern hard drive can only store 1/6 of its data per platter but you don't have to worry about that, do you?

    If you wanted to save a file larger than 700MB then the thinserver would just have to know to split it into multiple CDs but present the file as a single directory entry (file.mpg instead of file0.mpg file1.mpg and file2.mpg).

    Add to it room for at least two slot-load drives (although four would be even better, one in each corner) so you can access at least two CDs at any given time.

    Throw in a Linux thinserver (like the stuff Linksys or any number of companies use) to manange the contents of each CD/DVD.

    Result? Over 1TB of storage for around $1000. The only catch is that it is not meant for more than a handful of users at a time.

    But considering what an equivalent RAID would cost it doesn't seem like a bad idea. You could put every file you've ever downloaded into one box and each CD/DVD could show up as a separate directory on one master volume. Imagine that. Near-instant access to TB of info.

    If you use DVD-ROM drives, it's 1TB of read-only storage but if you use DVD-R/RW/RAM drives then it is 1TV of read/write storage! Wow, you could open your own Avalon!

    Please please someone start a project to help build something like this! I desperately want one but the crappy PowerFile version is junk because it relies on crappy Windows/Mac software and ties up a whole computers just to access the damn thing.

  • I have another problem to bring up, regarding the cheap disk backup situation. Hard drives are probably not a good choice for long term archiving, because they're built to have mechanical moving parts, so the oil and bearings will coagulate.

    There's a company called Solid Data which does file servers based off of RAM chips for main storage, with an optional hard drive periodic snapshot mirror. They learned the hard way that they had to periodically and automatically spin up the drives, because after about a year of solid operation, they had a failure on one server and it wasn't able to snapshot the data out before the data was lost, because the drives couldn't spin up.

    The hard drives are a cheap high performance backup, but they apparently don't do well on a long term shelf. Does anyone here have more info on that phenomenon?

    This type of suggestion ( http://slashdot.org/comments.pl?sid=01/07/19/15542 16&cid=48 [slashdot.org]) is my favorite so far. I've been waiting for that for a long time! I don't like tapes!

Yeah, it sounds cool but guess what, it isn't.
  • And when there's a fire, or an earthquake, or a lightning strike, you'll feel really dumb.

    Backups involve more than just having a redundant copy of the data in case of a drive (or a few drives) failing. Offsite storage and archiving are just as important - and while you could do this with the "build a second array for backup" approach, it's not really practical to move these heavy boxes around on a daily or weekly basis.

    Well, here's how we did our 525GB server for $4200 last December (would've been 600GB, but we decided to go RAID5.)

    Key parts, both hardware & software:
    • PIII-933
    • 256MB PC133 SDRAM
    • 4 Promise ATA/100 controllers
    • 8 IBM 75GB Deskstars
    • 3c905CTX (We don't have Gigabit yet)
    • Linux 2.4.x kernel
    • ReiserFS
    • Big F*cking Case


    We went this way because of the nature of the files to be stored (mean size=120MB, many over 200MB), and their purpose (download once, read a few times, delete.)

    NFS read times are around 20-25 MB/sec, just fine for us.

    A few points:
    1. Use only ONE drive per bus -- remember, this is IDE.
    2. Get a Big F*cking Case (tm) with at least a 350W power supply -- you're going to get some serious heat from 9 drives (the 9th is a 45GB drive, our boot device), so you'll need some pretty decent cooling going on.
    3. There is a hardware hack (check Tom's Hardware) that'll make the Promise ATA/100 controller into a IDE RAID controller -- try at your own risk. We didn't feel like messing with it.
    If I get some pictures up, I'll post the URL later.

    The heart of the storage component of the Active Web infrastructure is a terabyte server which will come online in Fall 2000. Because of the cost of commercial terabyte storage systems and the need for OS-level monitoring and customization, it was decided to build the departmental terabyte server from commodity components. The terabyte server itself is a dual-processor Dell PowerEdge 2400 running BSD/OS 4.2, with a AMI MegaRAID Enterprise 1600 hardware RAID adapter (four channel, Ultra160), and a link to the gigabit switch. The disk subsystem consists of two RAID enclosures of nine, 73GB Ultra160 disks each. Tape backup support for the terabyte server is provided by a generic PC connected via a two channel Ultra160 adapter to a dual drive Hewlett-Packard SureStore 2/40 tape library with a storage capacity of 3.2TB. Terabyte file systems will be exported to departmental UNIX systems using Kerberos authentication, and to Windows machines via Samba."
    This is from a ucsd "Active Web Equipment Infrastructure Plan" page. [ucsd.edu]. Found by google-ing "terabyte web server SDSC" [google.com] (since I couldn't find a google cache on michael's URL, but he says SDSC did it).

    Sure, you can get just as much disk space for an order of magnitude less. But you won't get their reliability, or their feature set. We use them exclusively for our storage needs. We have about 8TB of space on them right now. At anytime we can retrieve a recently deleted file or directory, do hot bakups, make new containers on the fly, hot swap out bad drives, add a new shelf of drives, chew gum and walk.

    In a production environment, where the data on those servers is the lifeblood of your company/organization, some DIY IDE RAID setup will not withstand the demands, or come close to yielding the results of a NetApp (or EMC, or Xiotech, or Compaq, etc..)

    These IDE RAID setups are fine for your mp3's or your personal or small workgroup fileservers. Just don't bet the farm on them.
