SPDK stands for Storage Performance Development Kit, which is an open-source software framework that helps to develop high-performance storage systems. SPDK was developed by Intel and is designed to provide low-latency and high-throughput access to storage devices such as solid-state drives (SSDs) and non-volatile memory express (NVMe) devices.
SPDK provides a set of libraries, drivers, and utilities that enable developers to build optimized storage solutions using modern hardware technologies. It includes an NVMe driver that bypasses the traditional kernel stack, allowing applications direct access to the NVMe device for improved performance. The framework also includes a user-space block device layer that allows applications to create virtual block devices with customized I/O paths.
Overall, SPDK enables developers to take full advantage of modern hardware technologies for building high-performance storage systems with low latency and high throughput.
