Sun has released its 10GbE Network Card. The card has a PCI Express x8 interface and starts at $498 per GigE port.

“Sun’s 10 Gigabit Ethernet Adapter extends CPU and OS parallelism to networking with its support for hardware-based flow classification and multiple DMAs. Using CPU thread affinity to bind a given flow to a specific CPU thread, it enables a one-to-one correlation of Rx and Tx packets across the same TCP connection. This can help avoid cross-calls and context switching to deliver greater performance while reducing the need for CPU resources to support I/O processing.”
