1.8TB Of Disk Space In A (Semi-)Normal PC

zdzichu writes "A friend of mine is building a personal server. He bought 17 of the cheapest IDE drives available and used Linux' LVM to get them together. The result? Almost two terabytes of disk space in regular x86 PC. The most juicy part - photos are here. For an operating system, he first tried the enterprise-ready PLD Linux Distribution, later he reinstalled Slackware Linux."

Large Disk Arrays

[JWSmythe]

We've done this before, but usually just go with arrays.. It's easy enough in a regular PC.. My prefered way to do it is, get something like the Promise UltraTrak SX8000, and put 8 200Gb IDE drives in it.. If you do RAID0, that'll give you 1.6Tb.. If you do RAID5, it'll give you 1.4Tb.. Linux sees it as a single SCSI drive. It's a lot cheaper than getting a whole bunch of SCSI drives.

With 8 250Gb Maxtor drives, he could have 1.75Tb per array. :) Then he could use the same method to append them to each other.. Whoohoo.. Imagine 14 of those arrays chained together, and let Linux append them to each other.. 24TB.. :)

I'm curious. What did he use to allow him to put so many IDE drives in the same machine? Off the top of my head, I believe he can use PCI cards that have 2 IDE controllers on each, allowing 4 drives.. Did he have 4 of those, plus the onboard IDE controllers? The pictures are going really slow to load..

I have a server now, that has 8 120Gb IDE drives, with a Promise internal RAID card, which works ok.. It freaks out under load though, so I don't recommend that. We don't use it for a web server any more. It's just a backup machine now, with 840Gb storage. :)

Are linux drivers ready?

If accumulating 1.8TB on a "consumer-level" PC is feasible, are the Linux LVM code and filesystem drivers ready to take on the 4TB barrier?

In kilobyte blocks, 2^32 blocks only allows for 4TB of data to be referenced. ext2 still has options to set for 1024 byte blocksize, and supports up to 4096 - which would be a 16TB barrier.
