ahh yes.. more acronyms...
SVC=SAN Volume Controller.
I am just trying to figure it out but have been told you can think of it as an array agnostic filer - similar to NetApp, but will work with any storage. Essentially this "controller (cluster)" is a gateway between your server and your storage whereby you can have any vendors arrays behind it and it presents logical LUNS to your server and it handles all of the I/O.
Do a quick google search on IBM SVC architecture. Received on Sun Dec 14 2008 - 20:31:23 CST
