Intel Gigabit ET and EF Multi-Port Server Adapters

The Intel® Gigabit ET and EF Multi-Port Server Adapters are Intel's third generation of PCIe GbE network adapters. Built with the Intel® 82576 Gigabit Ethernet Controller, these new adapt­ers showcase the next evolution in GbE networking features for the enterprise network and data center. These features include support for multi-core processors and optimisation for server virtualisation.

Optimised for Virtualisation

The Intel Gigabit ET and EF Multi-Port Server Adapters showcase the latest virtualisation technology called Intel® Virtualisation Technology for Connectivity (Intel® VT for Connectivity). Intel VT for Connectivity is a suite of hardware assists that improve overall system performance by lowering the I/O overhead in a virtualised environment. This optimises CPU usage, reduces system latency, and improves I/O through-put. Intel VT for Connectivity includes:

  • Virtual Machine Device Queues (VMDq)
  • Intel® I/O Acceleration Technology1 (Intel® I/OAT)
  • PCI-SIG Single Root I/O Virtualisation (PCI-SIG SR-IOV)

Use of multi-port adapters in a virtualised environment is very important because of the need to provide redundancy and data connectivity for the applications/workloads in the virtual machines. Due to slot limitations and the need for redundancy and data connectivity, it is recommended that a virtualised physical server needs at least six GbE ports to satisfy the I/O requirement demands.

Intel® Ethernet X520 Server Adapters

Intel's new family of Intel® Ethernet X520 Server Adapters are the most flexible and scalable Ethernet adapters for today's demanding data center environments. Data center networks are being pushed to their limits. The escalating deployments of servers with multi-core processors and demanding applications such as High Performance Computing (HPC), database clusters, and video-on-demand are driving the need for 10 Gigabit connections. Customers require flexible and scalable I/O solutions to meet the rigorous requirements of running mission-critical applications in virtualised and unified storage environments.
