A technique provides multi-tenancy within a data storage apparatus. The technique involves dividing, by processing circuitry, storage units of the data storage apparatus into multiple groups of storage units. The technique further involves forming, by the processing circuitry, segregated slice pools from the multiple groups of storage units. Each segregated slice pool is formed from a different group of storage units. The technique further involves allocating, by the processing circuitry, slices from the segregated slice pools to mutually exclusive sets of virtual storage processors (VSPs) on the data storage apparatus. Each mutually exclusive set of VSPs operates as a separate tenant of the data storage apparatus.
