SFN6122F & Xeon E5-2600 Deliver Winning Combination

• SFN6122F single-stream latency is superb over all message rates on Romley platforms, right up to the point of CPU core utilization

• Ultra-low jitter (sub-micro at 99Percentile)

• Benefits from Intel® Data Direct I/O (DDIO) and chipset IO – memory bandwidth

• Message rate headroom – 20Mpps with 4x sfnt-streams

Standard Server I/O Networking: RSS

• RSS spreads flows randomly over cores

• Packets within a flow go to same core

• Works well when– Connections

are long lived– One thread per

connection– And the thread

happens to run on the right core

– Great for network benchmarks

Smarter Server I/O Networking: Flow Affinity

• Hardware deterministically directs flows to the ideal core for handling the load

• Google developed Receive packet steering (RPS)

• Solarflare developed Accelerated RFS for multiqueue hardware

Other Tuning Tips

• RSS Spreading– Changing the default RSS spreading so that the card uses an RX queue per CPU

core. This is done by setting the driver’s module parameter rss_cpus=cores. See section “Receive Side Scaling (RSS)” on page 193-194 for more details. If you can, we also suggest you disable the irqbalancer service before doing this, as the irqbalancer tends to undo the good work of spreading the networking interrupts over the available CPU cores (see page 196)

• Enable LRO– Double check LRO is enabled using ethtool. As mentioned RHEL 6 libvirtd daemon

can cause this to be disabled. See “TCP Large Receive Offload (LRO)” on page 191-192 for details of LRO and how to change RHEL6 behaviour

• Interrupt Moderation– IF (and only if) you think the benchmark is latency sensitive then we suggest

disabling interrupt moderation. The driver by default uses adaptive interrupt moderation and tries to tune based on traffic patterns. However, if you know you have a ping/pong – transactional app then helps to disable this completely (see page 189 – “ethtool –C <ethX> rx-usecs-irq 0 adaptive-rx off”). BUT if you are streaming large blocks of storage data between the servers then don’t do this - the default is best.
