XtremeScale X2541
The World’s Lowest Latency 100G Ethernet NIC
The Industry’s 1st 100G NIC with Hardware Security


The X2541 single-port 10/25/40/50/100GbE Ethernet NIC is the most powerful member of the X2 family of XtremeScale products that redefine the price/performance of standard NICs for modern data centers.

Designed from the ground up for virtualized dense server environments Solarflare XtremeScale X2 adapters are the most cost-effective NICs in the industry for Ethernet connectivity. At the same time, XtremeScale acceleration provides record-breaking low latency and throughput needed for today’s modern class of applications. X2 is the most secure standard NIC with integrated hardware firewalls. XtremeScale X2 is the only general-purpose NIC with 2,048 Virtual NICs, programmable packet processing engine for network off-load and real-time packet/flow capture required by your network performance management and analytics platforms.
