MetaSAN is sold thru dealers that are listed on the Tiger Technology website. There is no "cheapest place" - the software is VERY inexpensive, and yes, you need a seperate license for every computer, and your server. And you need to have the hardware configured - which means a server computer, your disk drives, and your switch (either fibre or ethernet). The MetaSAN software is the least expensive part of putting together a shared storage environment. The drives, switch, server, and knowlege to cable all of this up, and make it work costs A LOT MORE than the MetaSAN software. So if you think you are going to spend $995 for some software, and have shared storage, you are mistaken.
Contact a dealer off the Tiger Technology website, and you will have great success with this product.
I am fairly familiar with the hardware that needs to be setup for a San so I understand the costs involved. Someone sent me your creative cow post on a low cost San and I wanted
to see how viable it is for our setup. You were somewhat unclear in the software aspect so this is why I am wondering what the deal is with licensing and what not.
