Abstract
Disk drives in a storage system are spun up in sequential stages. During each sequential stage a number of disk drives is spun up based on parameters related to the power requirements of the system. The parameters include the maximum current for the storage system, the number of disk drives currently in steady state, the steady state current required for a disk drive, and the spin up current required for a disk drive. High availability features are provided as further aspects of the spin up mechanism.
