determining whether any one of a set of quotas will be exceeded if the resource of the large storage array is provisioned comprising determining whether a project quota will be exceeded if the resource is provisioned, wherein the project quota limits a project and a project maps resources to applications, virtual data centers and departments, wherein resources from the project are shared between users under a same tenant in the multi-tenant environment of the large storage array, wherein the set of quotas includes a virtual pool quota, a project quota, and a tenant quota; denying the request to provision the resource if any one of a set of quotas is exceeded; and enabling the resource to be provisioned if none of the set of quotas is exceeded. ### Claim 2 (depends on 1) The method of claim 1, wherein determining whether any one of a set of quotas will be exceeded if the resource is provisioned further comprises determining whether a virtual pool quota will be exceeded if the resource is provisioned. ### Claim 3 (depends on 1) The method of claim 1, wherein determining whether any one of a set of quotas will be exceeded if the resource is provisioned further comprises determining whether a tenant quota will be exceeded if the resource is provisioned. ### Claim 4 (depends on 1) The method of claim 1, wherein determining whether any one of a set of quotas will be exceeded if the resource is provisioned further comprises: determining whether a virtual pool quota will be exceeded if the resource is provisioned; determining whether a project quota will be exceeded if the resource is provisioned if the virtual pool will not be exceeded; and determining whether a tenant quota will be exceeded if the resource is provisioned if the project quota will not be exceeded. ### Claim 5 (depends on 1) The method of claim 1, wherein receiving a request to provision a resource in a data storage system comprises receiving a request to provision at least one of capacity, processing time and bandwidth. ### Claim 6 An apparatus, comprising: electronic hardware circuitry configured to: receive a request to provision a resource in a data storage system at a distributed control platform, wherein the distributed control platform converts heterogeneous storage systems within one or more storage centers into what appears to a user as a large storage array, wherein the distributed control platform layers a multi-tenant environment over the large storage array, wherein each tenant of the multi-tenant environment is isolated from each other tenant of the multi-tenant environment; determine whether any one of a set of quotas will be exceeded if the resource of the large storage array is provisioned comprising determining whether a project quota will be exceeded if the resource is provisioned, wherein the project quota limits a project and a project maps resources to applications, virtual data centers and departments, wherein resources from the project are shared between users under a same tenant in the multi-tenant environment of the large storage array, wherein the set of quotas includes a virtual pool quota, a project quota, and a tenant quota; deny the request to provision the resource if any one of a set of quotas is exceeded; and enable the resource to be provisioned if none of the set of quotas is exceeded. ### Claim 7 (depends on 6) The apparatus of claim 6, wherein the circuitry comprises at least one of a processor, a memory, a programmable logic device or a logic gate. ### Claim 8 (depends on 6) The apparatus of claim 6, wherein the circuitry configured to determine whether any one of a set of quotas will be exceeded if the resource is provisioned further comprises circuitry configured to determine whether a virtual pool quota will be exceeded if the resource is provisioned. ### Claim 9 (depends on 6) The apparatus of claim 6, wherein the circuitry configured to determine whether any one of a set of quotas will be exceeded if the resource is provisioned further comprises circuitry configured to determine whether a tenant quota will be exceeded if the resource is provisioned. ### Claim 10 (depends on 6) The apparatus of claim 6, wherein the circuitry configured to determine whether any one of a set of quotas will be exceeded if the resource is provisioned comprises circuitry configured to: determine whether a virtual pool quota will be exceeded if the resource is provisioned; determine whether a project quota will be exceeded if the resource is provisioned if the virtual pool will not be exceeded; and determine whether a tenant quota will be exceeded if the resource is provisioned if the project quota will not be exceeded. ### Claim 11 (depends on 6) The apparatus of claim 6, wherein the circuitry configured to receive a request to provision a resource in a data storage system comprises circuitry configured to receive a request to provision at least one of capacity, processing time and bandwidth. ### Claim 12 An article comprising: a non-transitory computer-readable medium that stores computer-executable instructions, the instructions causing a machine to: receive a request to provision a resource in a data storage system at a distributed control platform, wherein the distributed control platform converts heterogeneous storage systems within one or more storage centers into what appears to a user as a large storage array, wherein the distributed control platform layers a multi-tenant environment over the large storage array, wherein each tenant of the multi-tenant environment is isolated from each other tenant of the multi-tenant environment; determine whether any one of a set of quotas will be exceeded if the resource of the large storage array is provisioned comprising determining whether a project quota will be exceeded if the resource is provisioned, wherein the project quota limits a project and a project maps resources to applications, virtual data centers and departments, wherein resources from the project are shared between users under a same tenant in the multi-tenant environment of the large storage array, wherein the set of quotas includes a virtual pool quota, a project quota, and a tenant quota; deny the request to provision the resource if any one of a set of quotas is exceeded; and enable the resource to be provisioned if none of the set of quotas is exceeded. ### Claim 13 (depends on 12) The article of claim 12, wherein the instructions causing the machine to determine whether any one of a set of quotas will be exceeded if the resource is provisioned further comprises instructions causing the machine to determine whether a virtual pool quota will be exceeded if the resource is provisioned. ### Claim 14 (depends on 12) The article of claim 12, wherein the instructions causing the machine to determine whether any one of a set of quotas will be exceeded if the resource is provisioned further comprises instructions causing the machine to determine whether a tenant quota will be exceeded if the resource is provisioned. ### Claim 15 (depends on 12) The article of claim 12, wherein the instructions causing the machine to determine whether any one of a set of quotas will be exceeded if the resource is provisioned comprises instructions causing the machine to: determine whether a virtual pool quota will be exceeded if the resource is provisioned; determine whether a project quota will be exceeded if the resource is provisioned if the virtual pool will not be exceeded; and determine whether a tenant quota will be exceeded if the resource is provisioned if the project quota will not be exceeded. ### Claim 16 (depends on 12) The article of claim 12, wherein the instructions causing the machine to receive a request to provision a resource in a data storage system comprises instructions causing the machine to receive a request to provision at least one of capacity, processing time and bandwidth.
