The Sun Dual 10GbE XFP PCIe ExpressModule (EM) is an x8 lane PCI Express (PCIe) 10-Gigabit Ethernet module that uses the Sun ASIC with XFP-based 10-Gigabit Ethernet optics. This EM requires an optical transceiver, either Sun part number X5558A SR (Short Reach) XFP Transceiver for the ExpressModule, or Sun part number X5560A-z LR (Long Reach) XFP Transceiver for the Express Module.
The Sun Dual 10GbE XFP PCIe EM provides the following features:
Two full-duplex 10-Gigabit Ethernet interfaces that use a small form factor 10-Gigabit Ethernet pluggable (XFP) optical transceiver with duplex LC fiber connector
IEEE 802.3ae 2002-compliant
Uses Sun ASIC and software for innovative throughput network design
Networking I/O virtualization supporting Solaris LDOMS 1.0 software
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
Jumbo frames support
IPv4, IPv6, and IPMP support
TCP and UDP checksum and CRC32C support
IEEE 802.1Q VLAN support
