High performance Low-latency, high-performance design resulting in a worst-case data-transfer latency of less than 2µs from any port at peak fibre-channel performance of 100 MBps. The latency can differ when the destination or device is a loop. Cascading Switches can be cascaded for large fabric support. Universal The switch ports are designed to support F, FL, and E-port modes of operation with the software selecting the optimum mode of operation. Performance A minimum aggregate routing capacity of 4 000 000 frames per second is specified for class 2, class 3, and class F frames. Non-blocking throughput of up to 800 MBps (0.8 GBps) is provided. A maximum switch latency of less than 2 µs is specified for class 2, class 3, and class F frames when the output port is free. Manageability | The unit is managed using the 10BASE-T Ethernet port for Telnet or Web-based | management using the IBM StorWatch Specialist. The switch also provides a front | operator panel for simple switch configuration and diagnostics. System components The system board is enclosed in an air-cooled chassis that is either mounted in a standard rack or used as a stand-alone unit. The chassis includes one or two power supplies, a fan tray, and an RJ-45 Ethernet connection for switch setup and management. GBICs The switch holds up to 16 GBIC modules. All interfaces have status lights that are visible from the front panel that let you see the status and activity of the GBICs. The GBIC modules supported are the short wavelength (SWL) and long wavelength (LWL) fiber-optic versions. If your installation requires installing less than 16 GBIC modules, the unused port positions are protected by a metal, spring-loaded door. SWL fiber-optic GBIC module The SWL fiber-optic GBIC module, with an SC connector color-coded black, is based on short wavelength 850 nm lasers supporting 1.0625 GBps link speeds. This GBIC module supports 50-µm, multimode fiber-optic cables up to 500 m (1640 ft) in length. Figure 2 on page 3 shows an SWL GBIC module. 2 IBM SAN Fibre Channel Switch: 2109 Model S16 Installation and Service Guide
