Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

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.
