Abstract: A batched unit of work is associated with a plurality of messages for use with a data store. A backout count, associated with a number of instances that work in association with the batched unit of work, is backed out. A backout threshold is associated with the backout count. A commit count is associated with committing the batched unit of work in response to successful commits for a predefined number of the plurality of messages. A checker checks whether the backout count is greater than zero and less than the backout threshold. An override component, responsive to the backout count being greater than zero and less than the backout threshold, overrides the commit count and commits the batched unit of work for a subset of the plurality of messages.

Abstract: An apparatus and method are disclosed to configure, format, and test, a data storage subsystem product. The method supplies a data storage subsystem product comprising one or more host computer ports, a processor, one or more data storage device ports, and one or more data storage devices interconnected to the one or more data storage device ports. The method further supplies a configuration appliance comprising a storage configuration. The method connects the configuration appliance to one of the one or more storage device ports, boots up the data storage subsystem product, discovers the configuration appliance by the data storage subsystem product, imports storage configuration data into the data storage subsystem product, formats the one or more data storage device, and tests the input and output data transfer rates for the data storage subsystem product, wherein the formatting and testing are initiated concurrently.
