4 Implementing SAN Internetworking Solutions Enterprise-level information technology (IT) departments often deploy storage configurations that include direct-attached storage, network-attached storage (NAS), and small, isolated storage area networks (SANs). These configurations often result in: • Isolated and inefficiently-used applications, data storage, and computing resources. • Costly, decentralized, and complex asset management. • Slow transactions and data access. • Inability to comply with government regulations that dictate data retention and security policies. The solution for these problems is to implement a internetworking strategy that consolidates IT resources and deploys an enterprisewide fabric. This chapter describes planning considerations for implementing SAN internetworking solutions using McDATA switch products. The chapter specifically describes: • SAN island consolidation. • Implementing business continuance and disaster recovery (BC/DR) solutions. • Consolidating and integrating Internet small computer systems interface (iSCSI) servers and storage.
