The host-optimized port provides the optimal port density and bandwidth for host connection.

The Cisco MDS 9120 switch is configured with 16 Host-optimized ports and 4 target-optimized ports. The Cisco MDS 9140 switch is configured with 32 host-optimized ports and 8 Target-optimized ports. The Cisco MDS 9100 series switches include a small pluggable (SFP) LC interface that is record-pluggable. Each port can be equipped with a short distance or a long distance SFP to connect 500 m and 10 km respectively.

Coarse Wavelength Division Multiplexing (CWDM) SFP aggregates multiple links on a single optical fiber through a low-cost, passive optical multiplexing/demultiplexing. All interfaces support 2 Gbps. Each target optimized port supports up to 255 buffer credit points for maximum scalability without additional licensing. Each host-optimized port supports 12 buffer credit points.

Advanced Traffic Management for high-performance perpetual Matrix

Advanced Traffic Management Integrated into the Cisco MDS 9100 series simplifies deployment and optimization of large matrices. By eliminating header congestion, the virtual output sorting ensures line rate performance on each port regardless of the traffic mode. Each port can obtain 255 buffer credit points to achieve optimal remote bandwidth utilization. When a long distance is required, 3500 credit points can be allocated to a single port in a 4-Fiber Channel port group.

PortChannel allows you to aggregate up to 15 physical ISLs into a single logical bundle to achieve optimal bandwidth utilization on all links. This bundle can be composed of any port of any module in the chassis to ensure that the bundle remains valid even if a module fails.

Matrix-Based Shortest? Team? (FSPF) multi-path can provide Load Balancing intelligence on up to 15 equal paths, and dynamic rerunning traffic in the event of a switch failure. QoS can be used to manage bandwidth and control latency to prioritize critical traffic. Fiber Channel congestion control (FCC) is an end-to-end congestion control mechanism based on feedback. It supplements the credit point mechanism between buffer channels to provide enhanced traffic management.

The routing between VSAN and VSAN enhances security and stability.

VSAN creates a hardware-based independent environment in a single physical SAN matrix or vswitch to achieve more efficient network utilization. Each VSAN can be used as a normal SAN region, maintaining its own matrix service to improve scalability and permanent availability. VSAN allows more users to share SAN infrastructure costs, ensure full traffic isolation, and independently control configurations based on VSAN.

The Cisco MDS 9100 series supports IVR between VSAN routes. This is the industry's first fiber channel routing feature. The IVR can selectively transmit data traffic between the initiator and the target on different VSAN, while maintaining independent control flows of each VSAN. With IVR, data can traverse the VSAN boundary, but the control plane is still isolated, thus ensuring the stability and availability of the matrix.

The most advanced diagnostic and troubleshooting tools in the industry

The management of large storage networks requires tools that can actively diagnose and verify the path and route latency, as well as mechanisms for obtaining and analyzing traffic.
