Utility
Adjusting storage capacity in a computing system
30 Sep 19
Adjusting storage capacity in a computing system that includes a computing device configured to send access requests to a storage device characterized by a first storage capacity, including: reducing data; determining, in dependence upon an amount of storage capacity saved by reducing the data, an updated storage capacity for the storage device; and exporting an updated storage capacity to the computing device.

Utility
Error correction processing in a storage device
30 Sep 19
Dynamically adjusting an error correction effort level of a storage device, including: receiving, from a storage array controller, an error correction effort level to perform when attempting to read data from the storage device; identifying that an attempt to read the data resulted in an error; and determining whether an amount of error correction effort level required to attempt to correct the error exceeds the error correction effort level to perform when attempting to read data from the storage device.
