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

Table 1-4
Hardware requirements for campus clusters
DescriptionItem
■ The storage switch (to which each host on a site connects) must have
access to storage arrays at all the sites.
■ Volumes must be mirrored with storage allocated from at least two sites.
■ DWDM links are recommended between sites for storage links.
DWDM works at the physical layer and requires multiplexer and
de-multiplexer devices.
■ The storage and networks must have redundant-loop access between
each node and each storage array to prevent the links from becoming a
single point of failure.
Storage
■ Oracle requires that all nodes use the IP addresses from the same subnet.
■ Symantec recommends two Network Interface Cards (NIC) per host for
LLT heartbeats. Oracle Clusterware requires one private and one virtual
IP for each host.
■ Symantec recommends a common cross-site physical infrastructure for
storage and LLT private networks.
Network
I/O fencing requires placement of a third coordinator disk at a third site.
The DWDM can be extended to the third site or the iSCSI LUN at the third
site can be used as the third coordination point. Alternatively Coordination
Point Server can be deployed at the third remote site as an arbitration point.
