Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I trust it has been long enough w/o other replies that I am not pushing you off the 0-reply list prematurely.
Although I have no experience w/ this item, it looks like a good, yea intriguing, piece of equip. I have no idea if it is worth the price.
Please don't forget that h/w redundancy is not a substitute for s/w back-ups. -- If bad data gets sent to the device, it will just wind up written on both drives & both copies will be NG. Their "a prefect backup at all times" is the one false claim I found on the page you linked to. (Not to mention the spelling mistake. )
Someone should find the author of that paragraph & make him/her stay after school to write:
"Hardware redundancy is not a substitute for software back-ups."
on the black board 100 or 1000 times.
The "fully hot-plug and hot swapable capabilities", however, mean that w/ one or more extra trays & drives you could make your own back-ups by periodically pulling one drive & inserting a spare -- the box would "heal" the RAID 1 array & the pulled drive would be a true back-up. You would need an extra tray & drive for each generation of back-up you wanted to maintain. You could also consider LVM snapshots or a versioning file system like ZFS.
Rick, thanks for the insight. I currently have been running a RAID 1 system for 5 yrs now with a hard drive backup system (incremental weekly, full monthly, and a remote copy at work). I've reached the 80% capacity of the drives and do not have the space to install more internal drives. Hot swap is not something I am looking for only because this is my home network and bringing down the server to replace hard drives is not an issue.
I'll be sure to do that once I buy it and get it up and running. Should be straight-forward considering that the system should see it as a hard-drive enclosure. I have 2 generic ones now and it was a cinch to get those up and running.
As promised, I am here to write that I bought the ezRAID enclosure and have successfully installed it. A very pain-free install and as I suspected, the OS saw the RAID enclosure as a typical FW HD. I highly recommend getting this if you need a redundant storage solution, with only a FW 400 card, and a couple of SATA disk lying around. I have pictures and instructions on getting this installed on a Slackware 10 box on my blog. PM me if you're interested.
