## Abstract

Techniques described herein relate to a method for providing software defined storage (SDS) services on edge information handling systems (IHSs). The method includes obtaining a composition request associated with performing an SDS service on edge IHSs, wherein the SDS service is associated with a minimum quantity of SDS nodes that is greater than a quantity of available edge IHSs; identifying a first edge IHS and a second edge IHS specified by the composition request; identifying a number of nodes associated with the SDS nodes; allocating heterogeneous compute resources of the first IHS and the second IHS to each SDS node of the SDS nodes; allocating a power domain to each SDS node of the SDS nodes; allocating portions of an at least one hardware resource set to each SDS node of the SDS nodes; and preparing the SDS nodes to perform the SDS service.
