With the NAS solution, is there any issue with network bandwidth? How fast is your data coming in?
 
wowza! just think of the pr0n..uhm...games!!!

lets say the average DIVX pr0n, uhm...game ISO is 650mb....
u could fit like 2000 DIVX pr0n0s, uhm..i mean games...all at one time!

wow!

(now lets see you span a norton ghost over 2000 cd's 🙂)lol

hope it all works out the way u want!

To move the data, it seems you will need a SAN on fibre channel. NAS plus ethernet seems like a major neck. Both of which are way out of your price range.

As other have mentioned, SCSI will be horribly expensive and running RAID0 is highly dangerous with that much data. A less risky approach using commodity drives will be to span the data though you lose the benefit of striping. W2K Server (and maybe Pro, not too sure) can span up to 32 drives using dynamic disk so theoretically you can do it all via software. Of course that will also slow down the works too.

You can try the 3Ware Escalade 6800 on RAID5 (8 drives) which give some measure of security. Idealy you would want a hot spare with so much data. It's availabe at Hyper Micro for about $310 or the 7810 for $445 and the 7850 for $629.

The only concievable case that would fit all this would be the Chenbro Ultra. I've used a few of these ->
Chenbro Ultra Case. It can hold about 9 drives on 3.5" adapters up front and 8 inside on a rear rack. The price with dual 400w power supplies comes to about $700 just for the case before cooling. Add the fans and it will be $850+ plus for the case before drives and other hardware.

The case was meant for SCSI so the IDe cable will be very hard to route.

You are asking quite a lot for such a small budget.

What I would do is just get 2 computers each with onboard raid and running 8 60GB Maxtor 7200RPM drives at $115 a piece, put those 4 drives in raid 0 (2 drives/channel), Then, I'm sure you could pick up some cheap pci raid cards, i got my 2 channel promise one for $85 and would be willing to sell it to you for cheaper if you wanted. all that storage stuff would be about $2010.

You could also fit it all in one box if you got 120GB drives. The cost would probably be more though.
 
That Promise card is cool, but it's only 33 MHz/32 bit, so the PCI bus is going to be a MAJOR bottleneck. I think unless you up the budget, it may be your only choice.
 
Thanks for your help. I have several vendors w/ different solutions getting me quotes. It turns out that there are Fibre Channel Raid setup's that support as much as 10 Tb. And with higher transfer rates than I was expecting. Price is a little high, but what's a guy to do?
 
Thomasbrain, considder the fact that IDE can't transfer more than 100 MB/sec, and the PCI bus is capable of 133 MB/Sec.
 
You can get TB and TB and TB, more is better but you better split them up because of defragment and stuff..

It took 3 days to initialize a 2.7 TB array I have here and thats on 1 machine. Unless you're a EXPERT in SAN, it'll cost you a lot of money to hook it up... and you'll need redudant switches and at least dual loop.

There is a NAS article from the IETF

NAS is good for storage but not performance.

NAS uses "file based access" instead of "Block-based storage" by SAN. Next revision of NAS will use DAFS, Direct Access File System. DAFS NAS product will ship first half of 2002.

 
Check out 3Ware Raid Cards - up to 8 IDE Drives. Also supports Raid 5 with hot swap / hot spare. Like others here, I would not use Raid 0 for this. I have something similar I have done with my Music (800 CDs in WAV - uncompressed file format over 6 75 Gb IBM drives).

With (8) 120 7200 RPM drives and a 3Ware card and a Lein-Li PC70 case you can get pretty close to what you are looking for.

Raid 5 with Hot Spare (8 total drives (1 for parity and 1 for hot spare = 6 drives of storage at 120 Gb each = 720 GB - not formatted). Larger drives are coming out early-mid 2002.

Not sure of the company off hand, but were looking into a fibre channel SAN for student backups at work with similar "sizes"...But it BLOWS you budget out of the water.

roughly 50k for 2 of these and a fibre channel controller. The controller is the expensive part... i think it was 25k alone for that...Not to mention 3k for getting the company to assist on setup...

EDIT: Translation = 1600 bucks isn't gonna get your what you want...😉
2 edit: 3.5 and 5.25 drives? Amatures....8 inch was da bomb.... 😛
 


<< just don't forget to backup your data on 3 1/4 inch floppies🙂 >>



I'd use 5 1/4 inch floppies... They're bigger, shouldn't they hold more data? hehehe
 
Yeah how are you going to back this up ?

I have a co-lo site with another 2.7 terrabyte sitting on hot switch over...

locally i only have a 20GB DLT IV 40 Compressed...

Looking at SDLT 220 GB

I have to change tape so often !

 
How exactly are you going to afford this on that budget?

Set realistic goals thats all I can say. I have never seen 180GB IDE drives oly 160GB ones at a price tag of $300 each. Regardless that much storage space will easily work out to $2000 just on an IDE setup. Forget about setting it up on Raid 0. We ran a 0.3TB server for a short time and it was a pain in the a$$ to run and maintain. Rebooting itself was a lengthy process just because it was Raid IDE.
