An adaptive method for multi-tenant oriented hybrid storage device resource isolation

The invention relates to an adaptive method for multi-tenant oriented hybrid storage device resource isolation. The method comprises the following steps: a system comprising a hybrid storage device, aresource isolation tool RIT and an adaptive precise speed limit algorithm module SAAT is arranged. N users access the hybrid storage device and transmit the desired throughput value of the user i tothe RIT; SAAT periodicity Based on the information loss rate Rmiss, overlap ratio op, Bandwidth BSD for low speed devices, Hybrid equipment actually measured user i throughput values and Calculatesthe specified speed limit values for the next cycle (and SAAT will result in a specified speed limit for the next cycle and to RIT, RIT is based on the specified speed limit values and control that actual throughput of the hybrid storage device, bringing the lat specified speed limit into effect, thereby bringing the actual read and write throughput of each user as close as possible to the upper limit of the expected throughp
