The Emulex 10GbE Virtual Fabric Adapters II and III for IBM® System x® are members of IBM's comprehensive networking portfolio of 10 Gb Ethernet (10GbE) converged network adapters (CNAs). They deliver industry-leading performance and scalability per watt, reducing requirements for power and cooling. Storage protocol offloads enable the efficient use of computing resources and the support of more virtual machines per CPU, and reduce the number of servers required to support data center demands. The adapters support fiber-optic or twin-ax copper cabling to maximize flexibility.
