You can buy Coraid and fill it with sata disks www.coraid.com, isn't
this an option ?

We have some "used servers" laying around (and I'd much prefer to use
existing hardware), but we also have (or will have in the not far
future) about ten or more SATA drives to stick into this array and so
far I didn't find a case to put them all in. I got the following
pointers from another mailing list:

http://www.mwave.com.au/newAU/mwaveAU/productdetail.asp?SKU=16010594

http://www.auspcmarket.com.au/index.php?redir=http://www.auspcmarket.com.au/show_product_info.php?input[product_code]=EL-PC-343Binput[category_id]=277
(18 drives)

Together with the decommissioned MoBo's/CPU's/Memory we have, these
might do the trick.

Thanks for the advise.

Thanks but it's not as cheap as I was hoping for (starts at $1995)
and is proprietary. I'd prefer to stick to something more open, like
iSCSI, and cheaper.

Leaving price aside, calling it proprietary is complete injustice
to the product.

Some history...
  http://lkml.indiana.edu/hypermail/linux/kernel/0404.2/1226.html

Today... a snippet from 'modinfo aoe'
description:AoE block/char driver for 2.6.2 and newer 2.6 kernels
author: Sam Hopkins s...@coraid.com
license:GPL
vermagic:   2.6.30.8-64.fc11.i686.PAE SMP mod_unload 686

Also...
$ yum list aoetools
aoetools.i586  23-2.fc11installed

In Debian...
  http://packages.qa.debian.org/a/aoetools.html

Last but not least...
  http://www.coraid.com/RESOURCES/AoE-Protocol-Definition

So we have a free software driver, in upstream kernel for several years,
maintained by the company itself, including free software user space tools
and with simple and accessible protocol definition --

I wish all hardware vendors were as open.

I take it back.

It's still very non-standard and will require me to stick to this
particular implementation (and their hardware).

With iSCSI, for instance, there are multiple open choices.

Hi,
I would consider buying used server and fill it up with hard drives. Then
using Linux or OpenSolaris to manage them.

 Hello,

 We have a few PowerEdge 860's which I mostly converted from our
 previous-generation Windows based system to Xen hosts for development
 on top of CentOS 5 (the production system is now mostly hosted
 abroad).

 These servers have space for only two internal disks and I'd like to
 try to convert a couple of them into servers of shared storage.
 I'm thinking of just setting them up to sync their disks using DRBD
 and providing access to the rest of the network via iSCSI.

 I'm looking for a way to attach lots of disks to them. So far the only
 options I found are MD1000/3000 from Dell, which are a bit too
 expensive for such a side-project.

 Is there another economical (and sane, speed-wise) way to get lots of
 disks on these system's bus?

 Thanks,

 --Amos
