Use gigabit Ethernet NICs. ■ Separate the storage SAN from the Oracle Cache Fusion using separate virtual local area networks (VLANs). ■ Use Link Aggregation (NIC teaming) for both the Filer while using single NetApp Virtual Interface (VIF) and the hosts. ■ Use multiple VIFs to different switches to handle switch-level failures. ■ Try to minimize the number of switch/router paths to reduce latency of iSCSI transactions, and use line-rate switches. ■ Maintain separate network paths for management plane access in the event of service network failures.
Chapter 1: Storage Stack Overview SAN A storage area network is a specialized network––that is, a communication infrastructure––that provides physical connections and a management layer, as well as access to high performance and highly available storage subsystems using block storage protocols. The SAN is made up of specific devices (or nodes), such as HBAs in the host servers, and front-end adapters that reside in the storage array. SANs use special switches, similar to Ethernet networking switches, as mechanisms to connect these SAN nodes together.
The main characteristic of a SAN is that the storage subsystems are generally available to multiple hosts at the same time, making SANs scalable and flexible. Unlike DAS or NAS, SANs require careful planning before implementation, because they have more interconnecting components as well as storage security, which is usually done in the fabric network. SANs differ from NAS in that SANs provide I/O access to hosts, whereas NAS appliances provide file level I/O. SANs also differ from other storage architectures in that they are dedicated storage networks and use their own network protocols (FC) and hardware components.
