X4 series adapters use the AMD Solarflare VNIC architecture. This provides the key to efficient server I/O, and is flexible enough to be applied to multiple server deployment scenarios. These deployment scenarios include:
- Kernel Driver
- This deployment scenario for standard operating system drivers uses one VNIC instance per CPU core. This allows network processing to continue over multiple CPU cores in parallel. The virtual interface provides a performance-optimized path for the kernel TCP/IP stack and contention-free access from the driver, resulting in extremely low latency and reduced CPU utilization.
- OpenOnload™
- This deployment scenario for a kernel bypass solution uses one VNIC instance per application. This leverages the host CPUs to full capacity and minimizes software overheads. AMD Solarflare has created both an open-source and Enterprise class high-performance application accelerator that delivers lower and more predictable latency and higher message rates for TCP and UDP-based applications, all with no need to modify applications or change the network infrastructure.
