The Cisco MDS 9134 Multilayer Fabric Switch, designed for midrange to large enterprise customers, provides line-rate 4-Gbps and 10-Gbps ports based on a purpose-built "switch-on-a-chip" application-specific integrated circuit (ASIC) with high performance, high density, and enterprise-class availability. The switch offers outstanding value by providing flexibility, high-availability, security, and ease of use at an affordable price in a compact one-rack-unit (1RU) form factor. With the flexibility to expand from 24 to 32 ports in 8-port increments and optionally activate 2 10-Gbps ports, the Cisco MDS 9134 offers the densities required for top-of-the-rack switch and edge connectivity in enterprise SANs. The Cisco MDS 9134 offers non-blocking architecture, with all 32 4-Gbps ports and the 2 10-Gbps ports operating at line rate concurrently.
