Analysis and Research on Cisco switch module ports

What is the Cisco switch module? The advanced traffic management feature in the Cisco switch module simplifies deployment and optimization of large networks, which allows many developers and users to extensively learn and study the principles of the Cisco switch module.

Cisco is a leader in the Exchange industry. Its various devices have excellent performance. Compared with other switch modules, Cisco switch modules have advantages in scalability, availability, and security. Cisco switch module adaptive 1/2 Gbps interface: provides high-performance connections and is compatible with existing devices.

ISL, the highest-performance inter-switch link in the industry): A PortChannel supports up to 16 2 Gbps links-the link can go through any port of any Cisco switch module in the chassis, thus improving scalability and durability. Smart network service: Virtual SANVSAN technology is used to establish a hardware isolation environment in a physical network.

Hardware-based smart frame processing provides access control list ACLs, and uses fiber channel congestion control (FCC) and matrix-level QoS and other advanced traffic management features to be transplanted from SAN Island to enterprise-level storage networks. Comprehensive Security Framework: supports RADIUS Authentication, SNMPv3, role-based access control, SSH, SFTP, FC-SP, virtual SAN, hardware Partition and access control list.

Advanced diagnostics: Provides intelligent diagnostics, protocol decoding, network analysis tools, and integrated call home functions to improve reliability, quickly solve problems, and reduce service costs. High port density and configuration flexibility: provides 16-port and 32-port configurations to improve performance, flexibility, and density. Each chassis supports 256 fibre Channel ports, and each rack supports 768 ports.

The smart and advanced features provided by the Cisco MDS 9000 Series Optical Fiber Channel Switching Module make multi-layer storage lan a reality. All Cisco switch modules include hardware innovations that significantly improve storage network scalability, availability, security, and manageability, thereby improving utilization and reducing total TCO ).

All Cisco MDS 9000 Series switching modules are hot swappable, including hot swappable minicomputers pluggable SFP) LC interfaces. Each port can be configured as a short wave length or long wavelength SFP, providing 10km m and connections respectively. All interfaces are adaptive 1/2 Gbps interfaces.

Each port supports 255 buffer credits, which can be expanded without adding a license. In addition, ports can be operated in the following modes: E port, F port, FL port, SD port, TE port, and TL port. The Cisco MDS 9000 Series fibre channel Cisco switch module provides two configurations: The DS-X9016 16 port switch module delivers the highest performance for the most important Storage Networking applications. The DS-X9032 32-port Switching Module achieves the optimal balance between performance and port density.

For the most important storage networking application, the DS-X9016 16-port fibre channel Cisco switch module delivers unparalleled performance. The adaptive 1/2 Gbps port provides 64 Gbps continuous total bandwidth, making the DS-X9016 an ideal solution for connecting high-performance storage subsystems and establishing ISL connections between switches.

The 32-port Fiber Channel switching module utilizes the DS-X9032 32-port Fiber Channel Cisco switch module to greatly improve storage network performance through transmission optimization. With the Cisco MDS 9000 Series Switch module, network builders can allocate bandwidth according to special application requirements, while reducing the switch floor space and reducing the total storage network deployment cost.

The DS-X9032 Switching Module provides the industry's highest Line Card port density and a total bandwidth of 32 Gbps. The bandwidth is allocated to eight groups. Each group has four ports and each port group has four Gbps of available bandwidth. If the DS-X9032 and DS-X9016 modules are integrated into a modular chassis, the customer will be able to design a storage network with the highest performance/price ratio in a variety of application environments.

The Cisco MDS 9000 Series Switching Module provides intelligent scalability. The Cisco MDS 9000 Series provides the highest port density in the industry, with a port number ranging from 16 to 256 per chassis. Because building a large storage network requires not only high port density.

As a result, Cisco has introduced many new features, making the multi-layer storage network a reality. Virtual SAN, advanced traffic management, hardware maintainability, and comprehensive security make the Cisco MDS 9000 Series A preferred platform for enterprises and provide them with the highest scalability and lowest TCO.

VSAN is an industry-leading product developed for the Cisco MDS 9000 series. It can create a hardware-based isolation environment in a SAN network and thus improve SAN utilization. Each VSAN can be used as a typical SAN.

Maintain your own matrix services to improve scalability and permanent availability. After a VSAN is created, multiple users can jointly bear the cost of the SAN infrastructure, ensure absolute traffic isolation and security, and independently control the configuration in VSAN units.

The advanced traffic management feature integrated into each Cisco MDS 9000 Series Cisco switch module simplifies deployment and optimization of large networks. Features: With PortChannels, You can aggregate 16 Physical ISLs into a logical connection bundle to improve the bandwidth utilization of all links. The connection bundle can contain any port on any module in the chassis. When the module fails, the connection bundle can be available.

The shortest path-First Protocol (FSPF) provides multi-path intelligence. When a switch fails, it can balance the load to 16 other cost paths to achieve dynamic traffic rerunning. Fiber Channel congestion control (FCC) is an end-to-end feedback congestion control mechanism that enhances the credit of Fiber Channel buffers to buffers BB between adjacent switches.
