An example method for memory resource provisioning using SAS zoning can include a serial attached Small Computer System Interface (SCSI) (SAS) switch and a provisioning manager (PM) executing on the SAS switch. A plurality of servers are communicatively coupled to the SAS switch, each server executing an operating system (OS) having access to one or more OS volumes. A host provisioning agent (HPA) executes on the OS of each of the plurality of servers. A plurality of memory resources are communicatively coupled to the SAS switch. Each memory resource can have a number of physical hard drives. A first portion of the memory resources is associated with zone groups corresponding to the plurality of servers. A second portion of the memory resources is associated with a provisioning zone group (PZG) hidden from the plurality of servers but available to the PM.
