Veritas Storage Foundation 5.1 SP1 for Oracle RAC Release Notes (5900-1513, April 2011)

Table 1-3

Hardware requirements for basic clusters (continued)

DescriptionItem

SF Oracle RAC requires that all storage disks 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.

DMP devices are mandatory for use as coordinator disks.

Disks

You can evaluate your systems for available disk space by running

the product installation program. Navigate to the product directory

on the product disc and run the following command:

# ./installsfrac -precheck node_name

For details on the additional space that is required for Oracle, see the

Oracle documentation.

Disk space

Each SF Oracle RAC system requires at least 2 GB.

Symantec recommends additional amount of at least twice the Oracle

SGA size.

RAM

See the Oracle Metalink document: 169706.1Swap space

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. These links must be of the same type;

you cannot mix 100BaseT and gigabit.

Symantec recommends gigabit Ethernet using enterprise-class

switches for the private links.

You can also configure aggregated interfaces.

Network links

At least one additional SCSI or Fibre Channel Host Bus Adapter per

system for shared data disks.

Fiber Channel or

SCSI host bus

Table 1-4 lists the hardware requirements for campus clusters in addition to the

basic cluster requirements.
