Dual Port Copper Gigabit Ethernet PCI-X Server Adapter Broadcom® Based

This product has been discontinuedEOL Notification

The Silicom PX-Series Server Gigabit adapters are 64-bit/133MHz PCI-X network interface cards that contain multiple / single independent Gigabit port/s on one PCI-X adapter.

Silicom’s PX-Series Server adapters are based on forth generation of Broadcom BCM57XX PCI-X Gigabit Ethernet controllers that features an industry leading performance for PCI-X server Adapters.

Industry-leading performance

Silcom‘s PX-Series Server adapters solution is designed for Servers and high-end appliances. The performance is optimized so that system I/O is not the bottleneck in high-performance networking applications.

Reliability, Availability, Serviceability

PX-Series Server adapters enables fault-tolerant via teaming. Traffic from the failed port is routed through up to seven other members of the team. PX-Series Server adapters come with software that offers the industry’s best performance and features. VLAN (802.1q) allow traffic segregation and data privacy. Support of 802.1p traffic prioritization gives administrations ability to offer Quality of Service (QOS) on the network.

Silicom‘s PX-Series Server adapters have an integrated hardware acceleration that performs TCP/UDP/IP checksum offload and TCP segmentation. The host processing offloads accelerators frees CPU for application processing.

Silicom‘s PX-Series Server Gigabit Ethernet adapters are the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.
