Abstract: Techniques are described herein for managing data in a storage array. A system includes a distributing unit to distribute compressible data and uncompressible data across compression-capable drives. The system also includes a vacating unit to vacate an excess chunklet to another drive in the storage array if a new compression factor is less than a default compression factor for the storage array.

Abstract: A data storage drive and a controller communicatively coupled to the data storage drive. The data storage drive includes a first region of storage space and at least a second region of storage space. The storage drive to reserve the first region of storage space for over-provisioning operations. The controller is to instruct the data storage drive to use the second region of storage space for over-provisioning operations.

Abstract: A system that includes a storage drive and a controller communicatively coupled to the storage drive. The storage drive includes a first region of storage space that is mapped to a virtual volume and at least a second region of storage space reserved for over-provisioning operations. The controller is to unmap an operable portion of the first region of storage space in response to aging of the storage drive so that the unmapped portion can be used for over-provisioning operations.
