and Nexus 5000 switches to support almost any fabric, including 100Mb, 1Gb and 10Gb Ethernet, as well as native Fibre Channel, Fibre Channel over Ethernet, InfiniBand over Ethernet, iSCSI and NAS.
Cisco will add FEX-Link support to its Nexus 7000 Series switches later this year. In addition, FEX-link architecture will enable the Cisco Unified Computing System to offer up to 160Gb of bandwidth per blade in the coming year.
Cisco also announced the second generation of its Nexus 2000 port extender series, top-of-rack networking devices that extend the management control plane of an end-of-row Nexus 5000 switch to each server rack in the data center row. The Nexus 2000 sits at the top of a server rack and provides connectivity for the servers, but it doesn't do any independent switching. Instead, it links back to an end-of-row switch, such as the Nexus 5000. The Nexus 2248 and 2232 now support 100 Megabit Ethernet and 10 Gigabit Ethernet.
