Abstract:
In one aspect of the present description, safe data commit scan operations of individual data storage systems of a distributed data storage system may be synchronized to reduce the occurrence of reductions in input/output (I/O) response times. In one embodiment, a set of safe data commit scan operations of the individual data storage systems of a distributed data storage system are synchronously timed to substantially overlap in time within a single synchronized safe data commit scan set interval to reduce or eliminate the occurrences of reductions in input/output response times outside the synchronized safe data commit scan set interval. Other features and aspects may be realized, depending upon the particular application.

Claim (Index 19):
A system, comprising:\n a plurality of data storage systems, each data storage system having a storage controller and a data storage unit controlled by a storage controller and configured to store data, wherein the storage controller of each data storage system has a processor and a cache wherein the plurality of data storage systems include a first data storage system configured as a primary data storage system and a second data storage system configured as a secondary data storage system; and a computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor of a storage controller to cause processor operations, the processor operations comprising:\n synchronizing a first set of safe data commit scan operations in a plurality of data storage systems, each safe data commit scan operation destaging data cached in a cache of a data storage system to a data storage unit of a data storage system, wherein synchronizing the first set of safe data commit scan operations includes: \n initiating a first safe data commit scan operation of the first set of safe data commit scan operations in a first data storage system; \n sending a first start safe data commit scan operation message from the first data storage system to a second data storage system; and \n in response to the first start safe commit scan operation message, initiating a second safe data commit scan operation of the first set of safe data commit scan operations in the second data storage system.
