Flareon Ultra SFN8522 Server Adapter PLUS Dual-Port 10GbE SFP+ The PLUS varia*f the Flareon Ultra SFN8522 Dual-Port 10GbE SFP+ Server I/O Adapter adds a suite of enabled software capabilities that provide out-of-the box support for ultra-lowlatency Onload-accelerated sockets as well as PPS and PTP time synchronizati*upport. The SFN8522-PLUS is capable of associating a ha*are time-stamp with every incoming and outgoing Ethernet frame for applicatio*oubleshooting or performance monitoring. These feature*ake the SFN8522-PLUS the ultra-low-latency Ethernet adapter of choice to deploy as a key component throughout Financial Tr*g infrastructures where two ports of 10GbE are required. CPU-Efficient Networking The Flareon Ultra SFN8522-PLUS dualport 10GbE Ethernet SFP+ server adapter delivers faster, more efficient processing of network traffic to accelerate a wide range of applicati*. The SFN8522-PLUS has 8 lanes of PCIe 3.1 minimizing latency and maximizing bus throughput between the adapter and the host. Flexibility in Operation In a virtualized environment the adapter supports hypervisor bypass via SR-IOV providing virtualized guests with near bare-metal network performance. Multiple physical functi* are also *ailable enabling the ports to be partitioned when connected to 802.1Q trunked switch ports with a logical interface per VLAN being presented to the operating system. Ports on the same adapter or acros*ultiple adapter*ay be bonded for redunda*peration. This redundancy support also extends to Onload™ with accelerated sockets capable of running across both Active-Passive and Active-Active LACP-enabled links. The SFN8522-PLUS enables the following licensed features enabled: Ultra-Low Latency The Flareon Ultra SFN8522-PLUS offers fast and efficient ha*are that optimize*cket flow to and from the user application. The SFN8522-PLUS unlocks unrivaled submicrosecond latency both at Layer 2 and TCP and UDP via Onload. Onload Onload is Solarflare’s industry’s le*g fully RFC-compliant kernel-bypass user-*ce TCP/ IP stack. Unrivaled applicatio*application TCP and UDP latency is *ailable with no modificatio*the applicati* being accelerated. Applicati* may communicate via Onload to any other RFC-compliant TCP/IP stack with seamless interoperability. Precision Time The SFN8522 is equipped with a Stratum 3 oscillator providing class-le*g clock stability. The SFN8522-PLUS enables the use of sfptpd, Solarflare’s time synchronization daemon, which leverages the adapter’s ability to apply ha*are time-stamps to incoming and outgoing Ethernet frames to synchronize its oscillator either via the PTPv2 protocol or a combination of PPS and NTP. Sfptpd also enables the Linux real-time clock to be synchronized to the external timing reference via the adapter clock. Any time-stamps obtained from either packet events or via the Linux time API may now be correlated directly with the external timing source. These features allow users to implement event traceability that exceeds the MIFID II requirements.
