Abstract: Described are techniques for processing I/O operations that may include: issuing, by a process of an application on a host, an I/O operation; tagging the I/O operation with a tag value in accordance with a process name associated with the process that issued the I/O operation; sending the I/O operation from the host to a data storage system; and determining, on the data storage system, an service level objective (SLO) for the I/O operation in accordance with the tag value of the I/O operation. The process name may include a first portion and a second customizable or configurable portion used to distinguish between different instance of the same application process. It may be determined which of multiple time-dependent SLOs for the process name is active and used with the I/O operation based on a receipt or processing time associated with the I/O operation.

Abstract: A virtualized storage array provides deduplication for a primary storage array that supports VVOLs. The VVOLs may be created for VMs that support host applications and guest OSs in a VDI environment. A VVOL is initially created as a virtualized managed drive that is backed by the virtualized storage array. The data is deduped by the virtualized storage array. After deduplication the data is either maintained on the virtualized storage array or moved to the primary storage array based on satisfying deduplication criteria such as reduction ratio.
