To meet scalability requirements while managing TCO, Cisco MDS 9500 Series of Multilayer Directors offers industry-leading port densities of up to 528 8-Gbps or 264 10-Gbps Fibre Channel ports per chassis, multihop FCoE, high per-slot performance, intelligent fabric services, VSANs for consolidating individual physical SAN islands while maintaining logical delineations, and IVR for sharing resources across VSANs. These capabilities enable the consolidation of an organization's data assets into fewer, larger, and more manageable SANs, thus reducing the hardware footprint and associated capital and operational expenses. For unified fabric deployments that have converged LAN and SAN using lossless Ethernet, the Cisco MDS 9500 Series of Multilayer Directors provides multihop FCoE capability to protect your investment in existing storage infrastructure with any-to-any connectivity across multiple protocols.

Enterprise Class Availability

The Cisco MDS 9500 Series of Multilayer Directors was designed from the beginning for high availability. Beyond meeting the basic requirements of non-disruptive software upgrades and redundancy of all critical hardware components, the Cisco MDS 9500 software architecture offers an outstanding level of availability. The Cisco MDS 9500 Series Supervisor Modules automatically restart failed processes, making the Cisco MDS 9500 exceptionally robust. In the rare event that a supervisor module is reset, complete synchronization between the active and standby supervisor modules helps ensure stateful failover with no disruption to traffic.
High availability is implemented at the fabric level using robust and high-performance Inter-Switch Links (ISLs). PortChannel capability allows users to aggregate up to 16 physical links into one logical bundle. The bundle can consist of any speed-matched ports in the chassis, helping ensure that the bundle can remain active in the event of a port, application-specific integrated circuit (ASIC), or module failure. The Cisco MDS 9500 takes high availability to a new level, helping ensure that solutions exceed the 99.999 percent uptime requirements of today's most demanding environments.

Integrated Mainframe Support

The Cisco MDS 9500 Series of Multilayer Directors is mainframe-ready, with full support for IBM System z FICON and Linux environments. Qualified by IBM for attachment to all FICON-enabled devices in an IBM System z operating environment, the Cisco MDS 9500 Series supports transport of the FICON protocol in both cascaded and non-cascaded fabrics, as well as an intermix of FICON and open systems Fibre Channel Protocol traffic on the same switch. VSANs simplify an intermix of SAN resources between z/OS, mainframe Linux, and open systems environments, allowing for increased SAN utilization and simplified SAN management. VSAN-based intermix mode eliminates the uncertainty and instability often associated with zoning-based intermix techniques. VSANs also eliminate the possibility of a mis-configuration or component failure in one VSAN affecting operation in other VSANs. VSAN-based management access control simplifies partitioning of SAN management responsibilities between mainframe and open systems environments, enhancing security. FICON VSANs can be managed using the integrated Cisco Data Center Network Manager; the Cisco CLI; or IBM CUP-enabled management tools, including SA/390, Resource Measurement Facility (RMF), or Dynamic Channel Path Management (DCM). Extended Remote Copy (XRC) acceleration improves performance and bandwidth utilization over WAN links for IBM z/OS Global Mirror dynamic updates.

Advanced Traffic Management

Advanced traffic management capabilities integrated into the Cisco MDS 9500 Series of Multilayer Directors simplify deployment and optimization of large-scale fabrics:

Virtual output queuing: Helps ensure line-rate performance on each port, independent of traffic pattern, by eliminating head-of-line blocking.

Up to 4095 buffer-to-buffer credits: Can be assigned to an individual port for optimal bandwidth utilization across distance.

PortChannels: Allow users to aggregate up to 16 physical ISLs into a single logical bundle, providing optimized bandwidth utilization across all links. The bundle can consist of any speed-matched ports from any module in the chassis, helping ensure that the bundle can remain active even in the event of a module failure.

Fabric Shortest Path First (FSPF) based multipathing: Provides the intelligence to load balance across up to 16 FC or FCoE equal cost paths and, in the event of a switch failure, dynamically reroute traffic.

Quality of Service: Can be used to manage bandwidth and control latency to prioritize critical traffic.

Port Bandwidth Reservation: Allows users to define dedicated bandwidth on a per port basis.

The Cisco MDS 9000 Family CLI is an extremely efficient and direct interface designed to provide optimal capabilities to administrators in enterprise environments.
Cisco DCNM (formerly Cisco Fabric Manager) is an easy-to-use application that simplifies management across multiple switches and converged fabrics. Focused on supporting efficient operations and management of virtual machine-aware fabrics, Cisco DCNM provides a robust framework and rich feature set that meet the routing, switching, and storage administration needs of present and future virtualized data centers. Cisco DCNM streamlines provisioning of the unified fabric and proactively monitors the LAN and SAN components. Cisco DCNM can be licensed for managing a combination of SAN and LAN environments.
Cisco DCNM can be used independently or in conjunction with third-party management applications. Cisco provides an extensive API for integration with third-party and user-developed management tools.

Comprehensive Solution for Robust Security

Addressing the need for fool-proof security in storage networks, the Cisco MDS 9500 Series of Multilayer Directors offers an extensive security framework to protect the highly sensitive data crossing today's enterprise networks. The Cisco MDS 9500 Series employs intelligent packet inspection at the port level, including the application of ACLs for hardware enforcement of zones, VSANs, and advanced port security features. VSANs are used to achieve higher security and greater stability by providing complete isolation among devices that are connected to the same physical SAN. IVR enables controlled sharing of resources between VSANs. In addition, FC-SP provides switch-to-switch and host-to-switch Diffie-Hellman Challenge Handshake Authentication Protocol (DH-CHAP) authentication supporting RADIUS or TACACS+, to help ensure that only authorized devices access protected storage networks. Cisco TrustSec Fibre Channel link encryption, available on the Cisco MDS 9000 Family 8-Gbps modules, allows you to transparently encrypt ISLs at line-rate 8-Gbps or the 10-Gbps Fibre Channel rate, providing an additional layer of protection for traffic within and between data centers.

Advanced Diagnostics and Troubleshooting Tools
