Optimized Network Connectivity
The IBM Flex System™ CN4054 10Gb Virtual Fabric Adapter is a 4-port 10Gb converged network adapter (CNA) for Intel processor-based compute nodes that can scale to up to 16 virtual ports and that supports Ethernet, iSCSI, and FCoE. The adapter supports up to 16 virtual NIC (vNIC) devices, where each physical 10GbE port can be divided into four virtual ports with flexible bandwidth allocation. The IBM Flex System CN4054 Virtual Fabric Adapter Upgrade adds Fibre Channel over Ethernet (FCoE) and iSCSI hardware initiator functionality¹.
Superior 10Gb/s Performance
The IBM Flex System CN4054 10Gb Virtual Fabric Adapter achieves line rate 10Gb/s performance with support for TCP/IP stateless offloads and TCP Chimney Offload. TCP Chimney Offload reduces system processor utilization, provides increased system performance and reduces overall system power requirements.
The IBM Flex System CN4054 10Gb Virtual Fabric Adapter provides the option to support FCoE, seamlessly converging Fibre Channel and Ethernet I/O while leveraging ten generations of proven Emulex Fibre Channel technology. By using a common infrastructure for Ethernet and storage networks, data centers can reduce capital expenditures (CAPEX) with savings of up to 30% for adapters and switches, and up to 80% for cables. Network convergence also reduces operational expenditures (OPEX) for power and cooling by up to 40%. FCoE is fully compatible with existing Fibre Channel infrastructures to fully protect investments in storage, switches, management applications and administrative expertise.
Optimized for virtualization
The IBM Flex System CN4054 10Gb Virtual Fabric Adapter offers the benefits and flexibility of an exclusive enhanced vNIC function, which enables bidirectional bandwidth management, dynamic bandwidth allocation and I/O convergence in a single end-to-end solution in partnership with IBM’s networking division. Each port on the IBM Flex System CN4054 10Gb Virtual Fabric Adapter can support up to four vNICs per physical port, for a total of 16 vNICs. Compute nodes like the x240 support up to two of these adapters for a total of 32 virtual NICs per system.
¹Support for storage networks using FCoE and iSCSI is available via FoD with IBM Part Number 90Y3558.
