The new Cisco UCS Virtual Interface Card 1227T improves flexibility, performance, and bandwidth for Cisco UCS rack-mount servers. The card offers a modular LAN on motherboard (mLOM) adapter. The mLOM slot can be used to install the card without consuming a Peripheral Component Interconnect Express (PCIe) slot. This provides greater I/O expandability.
A Cisco innovation, the 1227T card is a dual-port, 10GBASE-T (RJ-45), 10 Gigabit Ethernet, Fibre Channel over Ethernet (FCoE)-capable, PCIe mLOM adapter. It is designed exclusively for the M4 generation of Cisco UCS C-Series Rack Servers and the C3160 dense-storage server.
A stateless and agile server infrastructure provides the capability to define, create, and use interfaces on demand. That’s why the personality of the 1227T card is determined dynamically at boot time using the service profile associated with the server.
The service profile determines:
The 1227T card implements a Cisco fabric extender that unifies virtual and physical networking into a single infrastructure. It provides virtual-machine visibility from the physical network and a consistent network operations model for physical and virtual servers.
The usNIC improves the performance of software applications using the Message Passing Interface (MPI) instead of sockets or other communication APIs. It does this by bypassing the kernel when sending and receiving networking packets. The applications interact directly with the virtual interface card, which improves the networking performance of your high-performance computing application.
These adapters offer support for Microsoft Windows, Red Hat Enterprise Linux, SUSE Linux, VMware vSphere, and Citrix XenServer. (Note: The 1227T card must be connected to a 10BASE-T Cisco Nexus 2232TM-E 10GE Fabric Extender.)
Cisco SingleConnect technology unifies LAN, SAN, and systems management.
