Overview of the Cisco UCS C-Series Network Adapters


Note


The procedures in this chapter are available only when a Cisco UCS C-Series network adapter is installed in the chassis.


A Cisco UCS C-Series network adapter can be installed to provide options for I/O consolidation and virtualization support. Following are the available adapters:


  • Cisco UCS P81E Virtual Interface Card

Cisco UCS P81E Virtual Interface Card

The Cisco UCS P81E Virtual Interface Card is optimized for virtualized environments, for organizations that seek increased mobility in their physical environments, and for data centers that want reduced costs through NIC, HBA, cabling, and switch reduction and reduced management overhead. This Fibre Channel over Ethernet (FCoE) PCIe card offers the following benefits:


  • Allows up to 2 virtual Fibre Channel and 16 virtual Ethernet adapters to be provisioned in virtualized or nonvirtualized environments using just-in-time provisioning, providing tremendous system flexibility and allowing consolidation of multiple physical adapters.

  • Delivers uncompromising virtualization support, including hardware-based implementation of Cisco VN-Link technology and pass-through switching.

  • Improves system security and manageability by providing visibility and portability of network polices and security all the way to the virtual machine.

The virtual interface card makes Cisco VN-Link connections to the parent fabric interconnects, which allows virtual links to connect virtual NICs in virtual machines to virtual interfaces in the interconnect. In a Cisco Unified Computing System environment, virtual links then can be managed, network profiles applied, and interfaces dynamically reprovisioned as virtual machines move between servers in the system.
