The Flex System™ CN4022 2-port 10Gb Converged Adapter is a dual-port 10 Gigabit Ethernet network adapter that supports Ethernet, FCoE, and iSCSI protocols as standard. The EN4172 2-port 10Gb Ethernet Adapter is a similar adapter that supports Ethernet protocols. Both adapters also support virtual network interface controller (vNIC) capability, which helps clients to reduce cost and complexity.

These adapters are based on the Broadcom BCM57840 controller.<br><br>The CN4022 is based on the industry-standard PCIe architecture and is ideal for clients who use 10 GbE in their network infrastructure and who are looking for an entry price point for FCoE or iSCSI capabilities. The adapter ships standard with support for FCoE and iSCSi and with vNIC features that allow each physical port of the adapter to be virtualized into four vNICs.
