The 16-port 10 Gigabit Ethernet module provides up to 130 10 Gigabit Ethernet ports in a single Cisco 6500 Catalyst chassis and 260 10 Gigabit Ethernet ports in a Virtual Switching System (VSS) and is intended for LAN campus aggregation and access to Data centers, where fan-out and port density are very important. It consists of 4 groups of 4 ports each. Users can operate each group of ports either in oversubscription mode (2 to 4 ports per group of ports) or in execution mode (1 port per group of ports), which allows maximum flexibility for the use of some ports For connection to servers in performance mode and others for uplinks for wiring closets in oversubscription mode.
When in the run mode, up to 4 10 Gigabit Ethernet ports can be used to create a virtual switch link on a VSS.1 In addition, this 16-port 10 Gigabit Ethernet module has reduced its power consumption. Half the power per port is used compared to the 8-port 10 Gigabit Ethernet module, providing considerable savings for the customer.
