The document describes the network architecture and storage configuration of a clustered Oracle database system. Eth0 is the gigabit interconnect between nodes, eth1 is the administrative interface, and eth1:1 are virtual interfaces. Nodes are connected via eth0 and manage storage over Fiber Channel using HBAs. Storage is arranged logically into LUNs and physically across RAID arrays. Oracle database files are stored on clustered file systems mounted across nodes.
