Accelerating write operations in a storage system

Abstract:

Dynamically adjusting a number of storage devices in a storage system that may be utilized to simultaneously service write operations, includes: limiting a number of storage devices within a failure domain that may be simultaneously servicing write operations to a number less than a number of storage devices that may be lost without resulting in a loss of data; determining that an event has occurred that requires additional write bandwidth; and responsive to determining that an event has occurred that requires additional write bandwidth, increasing the number of storage devices that may be simultaneously servicing write operations.
