Turbo mode is a unique solution provided by HCI to improve the storage IO performance of VMs. It leverages SPDK and vhost technologies to migrate VM IO processing from the kernel space to the user space and allow IO traffic to directly access storage hardware without going through the OS kernel, thereby reducing virtualized resource scheduling costs and data copy operations. Turbo mode also optimizes IO path efficiency through single-depth IO polling, multi-depth IO pipelining, and large concurrent IO block splitting. Designed to reduce VM storage latency and increase IOPS, Turbo mode can take effect on each individual VM that has huge-page memory enabled and vmTools (Windows OS) installed. It is suitable for VMs deployed for IO-intensive services, such as Oracle databases and financial trading systems. Note: VMs with Turbo mode enabled cannot be configured with backup policies or be hot-migrated across datastores.
