The IBM Flex System CN4058 8-port 10Gb Converged Adapter is an 8-port 10Gb converged network adapter (CNA) for Power Systems compute nodes that supports 10 Gb Ethernet and FCoE. With hardware protocol offloads for TCP/IP and FCoE standard, the CN4058 8-port 10Gb Converged Adapter provides maximum bandwidth with minimum use of CPU resources. This is key in IBM Virtual I/O Server (VIOS) environments because it enables more VMs per server, providing greater cost saving to optimize return on investment. With eight ports, it takes full advantage of capabilities of all Ethernet switches in the IBM Flex System portfolio.
