Hi Chaps,

I'm putting together some new servers, and whilst I've been happy with our current config of Adaptec 5805's with bbu I've noticed these 5805Z cards, apparently the contents of DRAM is copied into onboard flash upon power failure.

Just wondered if anyone had any experience of this sort of technology yet?

So far my head is telling me to just go with what I know...

I just put a 5445Z in my new server but considering I just got it turned 
on about 2 hours ago I really can't say much about it.  I have several 
Adaptec cards with BBU and the Adaptec people talked me into trying the 
new Z version.  It's a bit more expensive on the front end but 
supposedly you don't have to replace batteries.  If you do go with the 
new Z version the first thing you'll have to figure out is where to put 
it.  I was wondering what the zip ties were for when I opened the 
package then realized it's to secure the unit to wherever you want in 
the chassis.  Kinda handy in a way but can also be a pain.
