SF Oracle RAC systems 

From two to eight HP-UX systems connected to the public network running HP-UX 11.23 PI. 

Symantec recommends that each system have two or more CPUs at 2GHz or higher. 

DVD drive 

One drive that is accessible to all nodes in the cluster. 

Disks 

Typical SF Oracle RAC configurations require that shared disks support applications that migrate between systems in the cluster. 

The SF Oracle RAC I/O fencing feature requires that all disks used as data disks or as coordinator disks must support SCSI-3 Persistent Reservations (PR). 

  Note   The coordinator disk does not store data, so configure the disk as the smallest possible LUN on a disk array to avoid wasting space.

Disk space 

See Disk space (local) 

RAM 

Each SF Oracle RAC system requires at least 256 megabytes. 

Symantec recommends 2 GB or more of physical memory. 

Swap space 

Symantec recommends at least double of main memory. 

Network links 

Two or more 100BaseT or Gigabit Ethernet links directly linking each node to the other node to form a private network that handles direct inter-system communication.  

Symantec recommends switches for the private network links. These links must be of the same type; you cannot mix 100BaseT and Gigabit. 

Fibre channel or SCSI host bus adapters 

SF Oracle RAC requires at least one built-in SCSI adapter per system to access the operating system disks, and at least one additional SCSI or Fibre Channel Host Bus Adapter per system for shared data disks.
