  Serial Attached SCSI (SAS)

All servers within the same building:  
  Storage over TCP/IP (iSCSI) or

- Your clients
- Other uses of the storage you can think of

then I'd highly recommend RHEL AS for the support aspects.

The HCL will at least cover the hardware compatibility
aspects.  RHEL AS comes with come clustering-failover
