The X3522 adapter has been engineered from scratch to provide absolute lowest latency. This has resulted in differences in its hardware capabilities and host interface from its predecessors that were designed by Solarflare, such as the 7000-series, 8000-series and XtremeScale X2-series. This chapter describes those differences, and resultant changes in deployment to take best advantage of them.
Note: Low-level changes that impact
acceleration technologies such as Onload, TCPDirect, and ef_vi are described in the
corresponding User Guide. See References.
