Your IT group must deliver always-on services while meeting corporate initiatives to reduce expenses. To improve application and data availability, while reducing total cost of operations, IT must provide disaster recovery and help ensure business continuity.

Cisco DCI solutions extend LAN and SAN connectivity across geographically dispersed active data centers. They help organizations like yours provide high-performance, nonstop access to business-critical applications and information.

These solutions support application clustering and virtual machine mobility between data centers to optimize computing efficiency and support business continuity. They offer flexible connectivity options for LAN and SAN extension across optical, Multiprotocol Label Switching (MPLS), or IP infrastructures. In addition, they provide:

  • Transparency to WAN network architecture and support for multi-data center architectures
  • LAN and SAN extension, with fault isolation for each data center
  • Resilient architecture to protect against link, node, and path failure
  • Optional payload encryption
  • SAN write acceleration and compression to increase replication options

Cisco DCI solutions offer a scalable, flexible platform that satisfies requirements for server and application mobility and business continuity.
