How to select an enterprise optical fiber switch

With the development of science and technology in the times, no matter what kind of enterprises have strict requirements on their own hardware facilities, the most popular switch is the so-called optical fiber switch, that is, a separate network of the entire storage can be connected to the enterprise LAN of the server.

It is characterized by the use of fiber channels with high transmission rates to connect to the server network, or the internal components of the SAN network, so that the entire storage network has a very wide bandwidth, this guarantees high-performance data storage. In this SAN storage network.

What plays a key role is the FC Switch that we often hear, also known as "Fiber Channel Switch" and "SAN Switch. It is much different from what we usually see and use Ethernet switches (mainly reflected in protocol support ). The following describes several excellent optical fiber switch products.

Cisco Mdms 9134

The Cisco MDS 9134 multi-layer matrix switch is designed for medium and large enterprises. It provides 4-Gbps and 10-Gbps line rate Ports Based on the dedicated "On-Chip switching" application-specific ic asic. In addition to eight ports, MDS 9134 provides the flexibility to expand from 24 ports to 32 ports.

2 10-Gbps ports can be activated to meet the density requirements of the optical fiber switch above the rack and the edge access switch in the enterprise SAN. The product adopts a non-congested architecture and supports all 32 4-Gbps ports and two 10-Gbps ports running at the same time at the same speed.

The MDS 9134 provides 10-Gbps ports that support multiple Fiber Channel connections and uses the 10-Gbps inter-switch link ISL) to connect to core products of the Cisco MDS 9000 Series. The Cisco MDS 9134 can also be stacked using a copper CX4 X2 transceiver to provide a cost-effective density of up to 64 ports.

In terms of security, MDS 9134 supports RADIUS and TACACS +, port security, matrix binding, fiber channel Security Protocol FC-SP) authentication between host and switch, secure FTPSFTP), Secure Shell version 2SSHv2), implements Advanced Encryption Standard AES (Simple Network Management Protocol version 3SNMPv3), VSAN, hardware-based partitions, broadcast areas, and role-based VSAN-based access control (RBAC ).

This product supports fast configuration and task wizard, so you can quickly and easily deploy it in a network of any size. Based on the Cisco MDS 9134 SAN-OS software, the MDS 9000 provides advanced storage network features and functionality and is compatible with the Cisco MDS 9500 series multilayer guide and the Cisco MDS 9200 series multilayer matrix switch, provide transparent and end-to-end services in core-edge deployment.

IBM System Storage SAN2061-420 fibre channel switches meet the needs of small and medium enterprise SAN environments. The product supports advanced optical fiber connection and business continuity functions, which are especially suitable for server cluster environments. In this configuration, the number of servers supported can be expanded from six to 18. each server is connected to the backup 2061-420 switch through a dual-fiber channel adapter, the vswitch is connected to the dual-controller storage system.

2061-420 is mainly used as the basic system for various smb san for small and medium-sized enterprises, but can also be used as a formal component to configure hierarchical enterprise SAN together with other components of the Cisco MDS 9000 Series. This feature helps extend the system as SAN requests, thus protecting investment.

2061-420 can be upgraded to 20 ports and will support 4 Gbps Fiber Channel servers and storage devices in the future. Its flexible design can be expanded by connecting to other Cisco MDS 9000 Series fiber switches through fiber channels as required.

It can also be used to connect two locations for remote data backup. Information lifecycle management (ILM) applications, such as the Storage Manager IBM Tivoli Storage Manager (TSM) running on production site servers, can write data to the tape system of a remote site.

When used with a storage system that supports 4 Gbps Throughput and server hardware, the transmission rate of all ports of the 2061-420 optical fiber switch can reach 4 Gbps. Each port is automatically coordinated to 4, 2 Gbps or 1 Gbps based on the capacity of the connected device or switch, with full duplex. When 20 ports are configured, the system transmission rate can reach 160.

The product supports adding a single optical transceiver without interrupting the operation of the fiber channel. In addition, the-firmware can be upgraded without interruption. You can download and activate the firmware while the Fiber Channel switch remains working properly.
