Abstract
Techniques are provided for processing of input/output (I/O) operations within a fault domain of a data storage system. One method comprises receiving I/O write requests from a client application, executing in a first fault domain, to write data; writing, by the storage control system, a primary copy of the data of the I/O write requests to at least one storage volume in the first fault domain using a designated assignment of the client application to the first fault domain; and writing a secondary copy of the data of the I/O write requests to at least one storage volume in an additional fault domain, wherein data responsive to I/O read requests from the client application executing in the first fault domain is obtained from the at least one storage volume in the first fault domain.
