What To Do With a Hundred Hard Drives?

Soulskill posted more than 6 years ago | from the build-a-hard-drive-cannon dept.

Data Storage 487

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?"

Just keep in mind these are *STRONG* magnets. When you take it apart the magnets may smash into each other. This could send particles flying away in a direction that, according to Murphy, is where your eyes are. I know this by experience, lucky for me I wear glasses.

Re:magnets (how to keep them?) (4, Informative)

profplump (309017) | more than 6 years ago | (#23786487)

Generally speaking, time alone will not reduce the strength of a permanent magnet. Heat, vibration, magnetic flux, and other forms of energy exposure can weaken permanent magnets. But in a box in your cabinet they are unlikely to encounter any sufficiently strong energy source to have a significant impact.

Re:Free Geek (2, Informative)

drspliff (652992) | more than 6 years ago | (#23786211)

I'm going to have to second this, but probably more towards the charity side.

It's quite easy for computer recycling charities to get working computers, but because of data security policies at a lot of companies they are not allowed to recycle hard-drives. This means that a disproportionate number of computers to hard-drives float around until they're finally scrapped (which overall costs the charity more time, effort and money).

For example, I have a 9gb and a 26gb drive in my main development machine - with a few 40gb and 125gb drives waiting for me to upgrade to (80% /, 67% /home used so far) - without working drives it's next to worthless and unusable.

Re:Free Geek (1)

industrialvegan (974786) | more than 6 years ago | (#23786333)

Yeah, agreed. Would be a super cool donation. My local free geek chapter will let anyone build a machine for free if they volunteer 24 hours of time at the store. For many people this is a great way to get a pretty nice decked out (as much as possible) system running Linux that they would not otherwise be able to afford. Granted, some of the machines are less than adequate for much, but at our chapter at least, they get p4's and up. In fact the last time I was down there they were even starting to get x86_64 machines. I say go for it. Just hope you can make people happy that the discs have been sufficiently wiped.

Gold leaf? Did I understand you correctly? The stuff that's 1/250000 of an inch thick, or the really thin stuff? There's probably not any gold inside the drives worth recovering--if it is still used in hard drive manufacture. I am struggling to find a reference for that, but I would expect it not to be the case. Gold is used increasingly rarely in electronics these days, as it's rather expensive.

Anonymous Coward | more than 6 years ago | (#23786215)

Even if you could scrounge up a bunch of old Parallel IDE quad-port Promise cards (pretty hard to do anymore, they were pretty rare even when they were in production) you can usually only get a max of three of those cards to work in a typical legacy PCI mobo due to various chipset and hardware resource conflicts. That gives you 12 IDE ports on the cards, plus two on the mobo, and at two drives (master + slave) per port, you would have a max of 28 possible drives connected and that's it.

Better have a heck of a power supply to feed 28 hungry old legacy IDE PATA drives and some fans to keep them all cooled.

There are several good reasons not to employ these as a backup solution. Using lots of smaller capacity drives will use significantly more power than fewer, larger drives. Also, these drives are old, which increases the probability that they will fail as they move along the bell curve. Save yourself the headache and powerbills, and donate 'em.

How About Just a Dozen? (4, Informative)

Doc Ruby (173196) | more than 6 years ago | (#23786155)

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 [google.com] 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.

One idea... (1, Interesting)

rcw-work (30090) | more than 6 years ago | (#23786165)

One idea I've been tossing around in the back of my head for a while is a backup-to-disk device which is kind of a cross between a tape library and a raid enclosure. It would emulate a tape robot and drives so that normal backup software could talk to it, and would just power up drives as they are needed and read/write to them. The advantages are that there is no expensive robot with moving parts, only a few drives need to be powered up at once, the drives will probably last longer if they stay off most of the time, "tape seeks" would stay nearly instant, and you don't need RAID controller ports for every drive you have (just a switching fabric for routing the ports you have to the drives you want to talk to.)

It'd probably only be practical with SATA or SAS (fewer wires and availability of multiplexing chips).

Maybe someone can do me a favor and steal my idea so I can buy some hardware like this fairly soon. :)

Sort them and build software raid arrays (1)

LoRdTAW (99712) | more than 6 years ago | (#23786191)

First thing I would do is sort them by their capacity. Anything under 100gb isn't really worth using as their capacity versus power consumption is poor. Either throw them out, give them away or sell them in bulk lots on ebay. Next thing to do is either buy multi port ata cards which are increasingly harder to find/expensive or get ata-to-sata converters and use multi port sata cards. Multi port sata cards can be had in 16 or even 24 ports and three or four cards in a single system could give you a serious storage platform. Plus sata equipment is cheap and esata enclosures, cables and adapters can easily be had for a few dollars.

Also consider ata-sata adapters will enable you to use a port multiplier that will split one sata port into five. On newegg you can buy a Supermicro eight port sata card for about $100. So with eight fan out bridges you have the ability to host forty drives on one card. Eighty with two cards in a single machine. It wont be a fast server thats for sure but it will do the job.

As for software I like MDADM on Linux but you want to scale up with iata or iscsi. I haven't used iata/iscsi but assemble your drives into arrays and get them up and online. Then install your iata/iscsi packages and get them talking to your servers.

there may be more value in the data than in the drive mechanism itself. you said they were used for video production...maybe there are some interesting outtakes or bloopers your employer would allow on youtube.

I spent last weekend wiping a stack of hard drives I'd accumulated so I can be charitable. They range from 500mb to 15gb. Guess it's a matter of opinion (and needs, as you point out) what is "too small".

And Tumbleweed [ http://ask.slashdot.org/comments.pl?sid=583611&cid=23786219 ], we can share the 1gb SCSI that sounds like a jet engine and 600mb Compaq IDE that clicks like a card in bike spokes... I haven't been skeet shooting since I was 15. :-D

SATA and port multipliers (0)

Anonymous Coward | more than 6 years ago | (#23786315)

You can use SATA port multipliers to put many disks on a single PC. Each port multiplier allows you to plug 5 disks on a single eSATA port. You can find cheap PCI SATA controllers with 4 eSATA ports. If you can find a PC with 5 PCI slots, that's a hundred disk.

Here are the ones I use on my NAS:
- port multiplier: http://www.addonics.com/products/host_controller/ad5sapm-e.asp
- SATA controller (PCI-X but works on PCI slots): http://www.addonics.com/products/host_controller/ads3gx4r5-e.asp

You also need one IDE to SATA bridge per disk. Maybe in bulk you can get good prices.

Data recovery services (5, Informative)

Loualbano2 (98133) | more than 6 years ago | (#23786321)

I would call your local data recovery service as they sometimes are interested in buying old drives of no particular size to use the controller cards on them.

Apparently, a lot of failed hard drives are not bad because of their physical platters, but because of the drive logic. These places need old drives for replacement controllers that you probably can't buy from the manufacturer.

Two Words (1)

macslas'hole (1173441) | more than 6 years ago | (#23786323)

Firewire ZFS Put them in firewire boxes and RAID them together with ZFS. IIRC firewire supports 64 devices per bus. I'm not sure if a dual connector card would have two busses or one.

Setup 1 machine and USB/Firewire them (3, Interesting)

IcephishCR (7031) | more than 6 years ago | (#23786349)

Pick the largest and buy up as many usb or firewire interfaces and drop them in a tower case with a psu for the HD's (get bus powered usb/firewire interfaces) and have a decent sized external array...

or use the larger ones as customer throwaways - when the video needs to go to the customer and its really big - ship them a cheap usb/firewire enclosure with a disc in it loaded with their video - if it doesn't come back then you've got more to spare....

Drobo, of course (1)

LoudMusic (199347) | more than 6 years ago | (#23786361)

I think what you're looking for is something like the Drobo [drobo.com] , but like me you would prefer it were a rack mountable 14+ drive enclosure. More like a cross between the Drobo and perhaps an Apple / Promise RAID [apple.com] unit.

Play around with the Drobo configurator on their website - it's interesting. Seems like four drives really don't open up the usefulness of their system. I'm sure the more drives there are the more effective it would be.

Probably not worthwhile (4, Interesting)

holophrastic (221104) | more than 6 years ago | (#23786415)

I'm actually thinking that it's a waste of effort. If they average, say, 100Gb each, then 100 drives means 10TB. 10TB these days is worth what? $2'000.00 worth of 1TB drives? Even less? More like $1'700.00 or so -- and that's for brand new drives, faster, better, more reliable, modern technologies, SATA, etc etc etc. Power consumptions too.

By the time you're done connecting all of these, and powering them, and cooling them, and dodging the broken ones, and finding a good use for it, and controllers to run them all, I can't imagine you'll be saving many dollars for storage, if any. Not to mention your time -- although it would be fun to spend.

So in the end, you'll have all of the benefits of a massive raid solution, but it'll be expensive to build, expensive to run, and take up a rediculous amount of world space (the real storage requirement).

I don't think they can compete as functioning hard drives. I think you should use them for some other purpose -- like art, or coasters, or to hold up your table.

For example, I have about 500 issues of national geographic from the 80's. They even have those file volume collection thingies so ten get held tegother as a set. I have some rediculous number like 50 sets. These things are totally useless to me -- unlike my nintendo power issues from the '80s that my mother sold about fifteen years ago -- so I got a piece of nice glass, and now have a coffee table that sits on these magazines instead of on legs. It's a nice piece of furniture from which you can reach in a pull out a blast from the past as you sip that coffee.

Google Do (2, Funny)

mrslacker (1122161) | more than 6 years ago | (#23786419)

> Now, I'd never use such an array for critical data storage,

Why not - Google do for GFS. Indeed, I worked for a search engine company and wrote something that had significant similarities to GFS - that is, a distributed high-performance redundant file system. Of course, you still need a machine for every 4 drives, but it can be done. Still requires manual maintenance however - the chance of individual drive failure if you run lots of them becomes quite high (your data is safe due to redundancy). Look around the net for references to GFS and Google data centers.

I have more than 100 matchbox SCSI external cases also with drives. They need a home.

Be practical -- screw the smaller drives. (4, Insightful)

merreborn (853723) | more than 6 years ago | (#23786445)

Why not just use the largest 10 or 20, and leave the rest of 'em in the closet for now?

Either your 10-20 drive pilot project will be a raging success, and your boss will be beating down your door to get the other drives plugged in, or it'll prove to be a huge waste of time, in which case you'll be glad you didn't bother with the smaller drives.

play with a clustered filesystem (0)

Anonymous Coward | more than 6 years ago | (#23786451)

Maybe have a go at a cluster filesystem. GlusterFS has been around for quite a while, however I have been using ceph stably for about a month now and it is amazing.. mind you it is still in the testing stages its worth checking out http://ceph.newdream.net/ .

Just give them to Free Geek or some other community that could benefit from a bunch of halfway decent drives like that

Laptop Backup Drives (2, Interesting)

Make friends with a computer recycler (1)

multi-flavor-geek (586005) | more than 6 years ago | (#23786525)

Someone who for the trade of taking some of the other junk hardware off your hands (the company may pay a fee in here somewhere, but its the responsible thing to do) he will give you a stack of identical old hp's, with ata 133 cards for each, and even an extra nic so they can all be channel bound... Think of the power if you have 8 2 ghz hp desktops sitting in a channel bound stack with 8 drives a piece in them? Then just make all of them boot off the same linux image, or do seven hard drives and a modded Ubuntu live cd in each and your ready to rock!
