[ale] Giant storage system suggestions

[Erik Mathis]

Although this wasn't a solution with performance in mind, but this a
really cheap 12T (8.2T usable) solution

and

iirc it was about $1300 9 months ago.

This readynas supports iscsi, nfs, cifs, and LVM snapshots. Also 2X
ethernet ports for bonding. If you have never used the readynas
products, they are basically linux boxes (using MD+LVM) and they have
a plugin system. They also have always been reliable for me. Anyway
its a cheap way to scale
