Unique Accelerated Performance

SFN7042Q's unique hardware-accelerated virtualized NIC (vNIC) architecture provides concrete benefits to multi-core computing. In many cases, network traffic that is directed to a single CPU core can overload the core and create a performance bottleneck. SFN7042Q can use up to 2048 vNICs to implement Receive Side Scaling and Solarflare Accelerated Receive Side Scaling (SARFS) and accelerate Receive Flow Steering (RFS) to distribute network traffic across multiple cores. These technologies allow the networking I/O processing to be spread across the available CPU cores, eliminating processing bottlenecks and dramatically improving application performance and scalability. SFN7042Q also improves data intensive key value storage applications such as NoSQL, memcached, Couchbase and other big data applications by accelerating throughput and reducing latency for compute and Ethernet storage. SFN7042Q also features hardware acceleration to optimize packet delivery, such as integrated layer 2 switching capability and VLAN insertion/ removal, along with TCP segmentation offload (TSO) to reduce CPU load.]

Scalable, Hardware-Assisted Virtualization

With 10x the number of vNICs and virtual PCIe functions than the competition, SFN7042Q 40GbE server adapter’s performance scales as the number of CPU cores and VMs increase, supporting more applications per physical server. SFN7042Q also supports NetQueue, VMQ and SR-IOV used to accelerate guest applications in leading hypervisors, such as ESXi, KVM and Hyper-V. This relieves network I/O bottlenecks dedicating full network bandwidth directly to VMs. 16 physical PCIe functions enable finer granularity and greater scalability when allocating Quality of Service (QoS) for optimized bandwidth utilization as I/O dynamically fluctuates.

Platform for Delivering Network Services

Flareon SFN7042Q enables deploying servers for a wide range of applications with a single server adapter. SFN7042Q with AppFlex™technology provides the flexibility to selectively add and control services. With an OpenOnload® upgrade, SFN7042Q can bypass kernel and networking overheads to deliver unmatched message rates with ultra low latency and low jitter. Upgrades for packet capture, security, networking monitoring, and precision time synchronization (PTP) with hardware time stamping are also available.
