PXLA8591SR - Intel PRO/10GbE LR Server Adapter

Industry-leading 10 Gigabit multi-mode fiber server connection

The Intel® PRO/10GbE SR Server Adapter—the industry's second-generation 10 Gigabit Ethernet adapter-enables the fastest Ethernet connectivity available. The Intel PRO/10GbE SR Server Adapter delivers industry-leading performance to bandwidth-intensive applications using a highly integrated PCI-X Intel® 82597EX 133 MHz/64-bit 10GbE controller. High-speed server connectivity once reserved for costly proprietary technologies such as high-performance computing clusters and grid-based computing can now be achieved with the industry-standard Intel PRO/10GbE SR Server Adapter.

Cost-effective 10 Gigabit performance on distances up to 300 m

Highly integrated PCI-X second-generation silicon for high performance

Smaller form factor with XPAK Optical Transceiver fits in standard server PCI slot
