Features

The Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter provides the following features:

■Two full-duplex 10 gigabit Ethernet interface that use a 10 gigabit Ethernet small form factor pluggable (XFP), optical transceiver with duplex LC fiber connector

■IEEE 802.3ae 2002 compliant

■Uses Sun’s own ASIC and software for innovative throughput networking design

■Networking I/O virtualization supporting Solaris LDOM 1.0. (VMware support planned for mid 07)

■Hardware-based flow classification for extending parallelism and virtualization to networking

■Up to 16 Receive DMA channels and up to 24 Transmit DMA channels, multiple receive and transmit Descriptor Rings and dedicated networking hardware resources (DMA, interrupts, buffer, and more) for each thread or strand

■CPU/thread affinity and CPU load balancing at L1,L2,L3 and L4

■Dynamic Reconfiguration (DR)

■Jumbo frame support (up to 9KBytes)

■IPv4/IPv6 and IPMP support

■TCP/UDP/IP checksum and CRC32C support

■IEEE 802.1Q VLAN support
