METHOD AND APPARATUS OF DYNAMIC PARALLELISM FOR CONTROLLING POWER CONSUMPTION OF SSDs

摘要

Embodiments are disclosed for adaptive power reduction for a solid-state storage device to dynamically control power consumption. Aspects of the embodiments include receiving a power limit command from a host; receiving power consumption feedback; using the power limit command and the power consumption feedback to calculate a new degree of parallelism; using the new degree of parallelism to control one or more of: i) processor parallelism, including activation of different numbers of processors, ii) memory parallelism, including memory pool length; and iii) nonvolatile memory parallelism, including activation of different numbers of nonvolatile memory devices.
