Abstract
Official abstract text for this publication.
A storage controller that includes a cache receives a command from a host, wherein a set of criteria corresponding to read and write response times for executing the command have to be satisfied. The storage controller determines ranks of a first type and ranks of a second type corresponding to a plurality of volumes coupled to the storage controller, wherein the command is to be executed with respect to the ranks of the first type. Destage rate corresponding to the ranks of the first type are adjusted to be less than a default destage rate corresponding to the ranks of the second type, wherein the set of criteria corresponding to the read and write response times for executing the command are satisfied.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: receiving, by a storage controller that includes a cache, a command from a host, wherein a set of criteria corresponding to read and write response times for executing the command have to be satisfied for a stringent requirements application, and wherein destage task control blocks maintained in the storage controller store information about processes as data to be written is passed from the host through the cache to storage devices cou…
