Intel® 82599 10 Gigabit Ethernet Controller

Industry-leading, energy-efficient design for next-generation 10 Gigabit performance and multi-core processors

SFP+ Connectivity

X520 Adapters with SFP+ connections support 10GBASE-SR, 10GBASE-LR and SFP+ Copper Direct Attach physical media

Load balancing on multiple CPUs

Increases performance on multi-processor systems by efficiently balancing network loads across CPU cores when used with Receive-Side Scaling (RSS) from Microsoft or Scalable I/O on Linux*

Receive Side Scaling

Multiple Rx queues enable the efficient distribution of network receive processing across multiple CPUs in multiprocessor systems

Direct Cache Access (DCA)

The I/O device activates a pre-fetch engine in the CPU that loads the data into the CPU cache ahead of time, before use, eliminating cache misses and reducing CPU load

Time Sync (IEEE 1588*, 802.1as)

Enables networked Ethernet equipment to synchronize internal clocks according to a network master clock; endpoint can then acquire an accurate estimate of the master time by compensating for link latency
