ASM, RAID levels and EqualLogic SAN?

 Does anyone have experience with ASM on Dell EqualLogic SAN?

We're looking at replacing an old Oracle9iR2 RAC cluster on Windows 2000 with newer servers, OS and storage - and maybe not RAC but possibly RAC One Node or VM.

My question is about storage.  We are currently having issues with fast hard disks in a 2-node cluster, where the controllers start fighting each other during high I/O and RAID-1 disk rebuilding.  The Dell EqualLogic iSCSI SAN array looks like a nice solution - put all of the caching, RAID levels, etc. into the storage unit and let it present a single cached version of storage to all attached nodes.

Howdy, Stranger!
