Description

|---|
Storage Foundation systems
|
Two to eight systems with two or more CPUs at 2GHz or higher.
|
RAM
|
Each Storage Foundation system requires 2 GB or more of physical memory.
|
Network links
|
Two or more private links and one public link.
Links must be 100BaseT or Gigabit Ethernet directly linking each node to the other node to form a private network that handles direct inter-system communication.
Symantec recommends Gigabit Ethernet using enterprise-class switches for the private links.
|
DVD drive
|
One drive that is accessible to all nodes in the cluster.
|
Fibre channel or SCSI host bus adapters
|
Storage Foundation 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.
|
Disks
|
Typical Storage Foundation configurations require that shared disks support applications that migrate between systems in the cluster.
The Storage Foundation 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
|
SF Oracle RAC space requirement:
-
total: 2.6 G
-
/opt: 1.4 G
-
/usr: 200 KB
-
/tmp: 512 MB
-
/var: 32 MB
-
/var/tmp: 700 MB
|
Swap space
|
Two times the main memory.
