XtremeScale™ 8042
40GbE Dual Port NIC for PCIe 3.1 x8 Slots

For IT architects building highly efficient software defined data centers, the XtremeScale
8042 is a full-featured enterprise-class NIC supporting a long list of advanced network
protocols and operating platforms. The 8042 is also a platform for data center-wide NIC
Fabrics delivering advanced acceleration, telemetry and security services which scalewith each server, VM or container. For data center traffic engineers, the fabric services
running on XtremeScale adapters are software defined through specific firmware
products.

A full-featured 10GbE NIC

Features and Benefits
FOR PCIE 3.1 X8 SLOTSThe XtremeScale 8042 is available for servers with PCIe 3.1 x8 slots. The XtremeScale
8042 is designed specifically for situations where you need 40GbE performance but you
have only PCIe 3.1 x8 slots available.

A POWERFUL 40GBE NIC

With two 40Gbps ports, the XtremeScale 8042 provides ultra high throughput. Inaddition, the ScaleOut Onload application is included and uses kernel bypass technologyfor latency as low as 2 μs.

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

A SMART NIC

Inside the ASIC of every XtremeScale 8042 Ethernet NIC is an XtremePacket™ Engine
which allows this general purpose NIC to inspect every packet 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. Solarflare’s
8000 Series support the industry’s first Smart NIC fabric for the enterprise, including
shrink-wrapped applications for micro segmented acceleration, packet monitoring andsecurity.

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