Oracle Disk I/O Tuning
Chapter 5:
Configuration of CFS or Raw Devices
It is important to understand that
volumes are the basic storage components that an Oracle database
utilizes. The volumes, as created by the CVM, are accessible by all
members or nodes of the cluster. This is an important distinction in
the RAC environment. A volume can be accessed either directly by the
RAC database as a raw partition, or through mounted file systems
such as a CFS, as shown in Fig 15.17
Figure 5.17 Veritas
Cluster Volume Management
Configure NFS file system
Using NFS mount for the shared storage
for the RAC database system, provides yet another option. In this
section, we will explain the usage of NFS type shared storage
structures by looking at the Filer System supplied by Network
Appliance System.
Storage Infrastructure:
-
One Network Appliance
F2XX/F7XX/F8XX/F9XX filer with Data ONTAP™ 6.1.3R2 or later
-
One Gigabit switch with at least
four ports
-
One Gigabit NIC in the filer
-
One or more disk shelves, based
on the disk space requirements
