I currently have a PERC H700 RAID card in my file server. The issue is the card has stopped working! I want to replace it, and import the current disk config into the replacement card, right? My card is marked:

Dell PERC H700 (1GB) RAID Controller card:

DPN=0GRXYF, CN-OGRXYF-75435-373-002D-A02

Dell Netlist 1GB PC2-6400 DDR2-800 Cache Module: NHW127R21207F-D64NMHDO

Questions:

1)There are a few different DPNs for essentially the same card it seems! Can I use any of them to replace mine?

2)If I get a 512MB cache card, can I just swap over my existing-GB cache card to the replacement card?
