Cisco DS-C9120-K9 MDS-9120 (DS-C9100 Series) 20-Port Multilayer Fabric Switch / Fiber Channel Switch

The Cisco MDS 9100 Series elevates the standard for Fibre Channel fabric switches, bringing Cisco Intelligent Networking to small and medium-scale SANs and data-center edge applications. The Cisco MDS 9100 Series provides the ideal balance of cost, performance, and enterprise-class features in a compact 1RU form factor. Available in 20- and 40-port configurations, the Cisco MDS 9100 Series offers the port densities required for a wide variety of storage environments. Providing class-leading scalability, availability, security, and management, the Cisco MDS 9100 Series enables users to deploy high-performance SANs with low TCO. Layering a rich set of intelligent features onto a cost-effective, small-profile switching platform, the Cisco MDS 9100 Series addresses the cost, performance, ease of management, and connectivity requirements of small and medium-scale storage environments and provides full-feature compatibility with Cisco MDS 9500 Series Multilayer Directors and the Cisco MDS 9200 Series Multilayer Fabric Switches for transparent, end-to-end service delivery in large data-center core-edge deployments.

Cisco MDS 9100 Series switches optimize connectivity by matching switch-port performance to the requirements of connected devices. Target-optimized ports are configured to meet the bandwidth demands of high-performance storage devices, servers, and Inter-Switch Links (ISLs). Host-optimized ports deliver best-in-class port density and optimal bandwidth for host-attach. The Cisco MDS 9120 model switch is configured with 16 host-optimized ports and 4 target-optimized ports. The Cisco MDS 9140 model switch is configured with 32 host-optimized ports and 8 target-optimized ports. Cisco MDS 9100 Series switches include hot-swappable, Small Form-Factor Pluggable (SFP), LC interfaces. Individual ports can be configured with either short- or long-wavelength SFPs for connectivity up to 500m and 10 km, respectively. Available coarse wavelength-division multiplexing (CWDM) SFPs support aggregation of multiple links onto a single optical fiber through a low-cost, passive, optical multiplexer/demultiplexer. All interfaces are 2 Gbps compatible. Up to 255 buffer credits per port are supported on target-optimized ports for maximum extensibility without the requirement for additional licensing. Host-optimized ports support 12 buffer credits per port.
