PRODUCT BRIEF

XtremeScale™ 8041
40GbE Single Port NIC

For IT architects building highly efficient software defined data centers, the XtremeScale
8041 is a full-featured enterprise-class NIC supporting a long list of advanced network
protocols and operating platforms. The 8041 is also a platform for data center-wide NIC
Fabrics delivering micro segmented acceleration, telemetry and security services whichscale with each server, VM or container. For data center traffic engineers, the fabricservices running on XtremeScale adapters are software- defined so that network trafficcan be shaped and automated using well defined APIs.

A full-featured 10GbE NICFeatures and Benefits
A POWERFUL 40GBE NIC

With a single 40GbE port, the XtremeScale 8041 provides ultra high throughput. Inaddition, the ScaleOut Onload application is included and uses kernel bypass technology
for application acceleration and reduced CPU utilization.

A SMART NIC

Inside the ASIC of every 8041 Ethernet NIC is an XtremePacket Engine, which allows thisgeneral-purpose NIC to inspect every packet at line-speed. Software defined network
engineers can then use Solarflare APIs to shape the network traffic.

A new class of Smart NIC with the FPGAlike ability to inspect packets and shapetraffic at line speed

A PLATFORM FOR A SMART NIC FABRIC

Hyperscale cloud service providers are micro segmenting their network services bydeploying them in proprietary Smart NIC fabrics which scale with each server. The 8000
Series from Solarflare support the industry’s first Smart NIC Fabric for the enterprise,
including shrink-wrapped applications for micro segmented acceleration, packet
monitoring and security.

A software defined platform for micro
segmented acceleration, security andvisibility fabric services which scale withevery server, VM or container
