I am going to play devils advocate here: is there a specific reason you want to use GFS in this setup? NetApp has excellent NFS and CIFS support and it looks like you already paid for both and HA option for NetApp (270c is a clustered filer).

I wasn't going to use GFS.
I am going to setup an HA cluster with Oracle services.
So it is not simultaneous cluster node access to the disk storage.
(Kind of like HP Service Guard or Veritas Cluster Services).

Do not get 10gbE. First, I don't think you can get 10gbE interfaces in FAS270. Second, FAS270 won't be able to saturate even 1gb link. The bottleneck is usually the filer CPU. It does support link aggregation but you won't see much of the difference vs active/passive bonding. -Alex

Yeah, I should ask NetApp if I can get FOUR nic's into the NetApp.
Then I can do two uplinks (aggregated) to Switch1--Node1,
and two uplinks to Switch2--Node2, then have the Nodes crossconnected
with heartbeat......

Hmmm, THANKS!
