Ok, this is my beef with NetApp. We have a NetApp F720 with a single disk shelf. The F720 "brain box" has two power supply units that slide into the back on the right and left side, each having it's own 48V DC connectors (about the size of LS1010 power supplies).
Now the disk shelf. It has two power supplies that slide into the front and connect into the backplane with no connectors on the front. A fixed connector assembly is located on the back. Just one. One!
No A side. No B side. Just one +/-/GND. We gave NetApp a call and their workaround was "you could use a diode and connect both A & B wires to the unit". Uhh... thanks. They also told us their design engineer had already been slapped on the hand, and they are working on their next version.
It was an interesting gotcha for our server engineer who wansn't too farmiliar with DC power plants.
Now, does anyone know of a diode that can do 10A at 48V? Any EE's out there?

One thing we'd like to do is run the message store over Gig-E on network attached storage. Two of the vendors we've been looking at claim performance issues running this solution over NFS. Does anyone know of a carrier-class mail solution that will run well on NAS?Take a look at NetApp. My company (unfortunately) signed an NDA with NetApp, but they've posted that Yahoo uses NetApp for their e-mail: http://www.netapp.com/partners/catalog.cgi/company/28 Rumor has it (no, I'm not violating my NDA) that Hotmail also uses NetApp. -Plenty- of other large sites use 'em for e-mail. Just call a NetApp sales person and and ask for the list. It's impressive. I do believe it contains some carrier-class implementations. Mike
