Fibre Channel Hardware and Software Configurations
• Each node must include the following minimum hardware peripheral components:
– One or two hard drives (36-GB minimum) in the internal hard-drive bay
– Three Gigabit NIC ports
– Two Fibre Channel HBAs
• Each node must have the following software installed:
– Red Hat Enterprise Linux software (see Table 1-1)
– Fibre Channel HBA driver
– OCFS2 module for the kernel and the configuration tools for OCFS2
NOTE: OCFS supports two kinds of kernel, namely hugemem and Symmetric MultiProcessing (SMP).
Choose the OCFS type according to your kernel.
• The Fibre Channel storage must be configured with the following:
– A minimum of three LUNs created and assigned to the cluster
– A minimum LUN size of 5 GB
Configuring Networking and Storage for Oracle RAC 10g
This section provides information on setting up a Fibre Channel cluster running a seed database
and includes the following procedures:
• Configuring the Public and Private Networks
• Securing Your System
• Verifying the Storage Configuration
• Configuring Shared Storage Using OCFS2
• Configuring Shared Storage With ASM
Configuring Oracle RAC 10g database is complex and requires an ordered list of procedures.
To configure networking and storage in a minimal amount of time, perform the following procedures
in a sequence.
Configuring the Public and Private Networks
This section presents steps to configure the public and private cluster networks.
NOTE: Each node requires a unique public and private Internet Protocol (IP) address and an additional public
IP address to serve as the virtual IP address for the client connections and connection failover. The virtual IP
address must belong to the same subnet as the public IP. All public IP addresses, including the virtual IP address,
must be registered with DNS.
