An exemplary embodiment can provide an admin partition in a subnet of a network environment, associated with a resource domain at the fabric level of the network environment. The admin partition can be defined by a P_Key that is stored in a fabric-level database. Each fabric resource is identified by an identifier that is stored in the fabric-level database. When fabric resources are added as members to the resource domain, a relationship is created between the P_Key and the identifier of the fabric resource, where the relationship defines the resource as a member of the admin partition. Access rights can be granted based on the relationship. ## Claims ### Claim 1 A method of correlating fabric-level group membership with subnet-level group membership within a network fabric, comprising: providing a computer including one or more microprocessors; providing, within the network fabric, a fabric manager associated with a fabric manager database; creating a resource domain within the network fabric, wherein the resource domain is a logical grouping of fabric resources; assigning a first partition key (P_Key) of a plurality of P_Keys to an admin partition in a subnet of the network fabric; assigning a second P_Key to a first data partition within the resource domain; assigning a third P_Key to a second data partition within the resource domain; and storing, within fabric manager database, a relationship between the admin partition and the first and second data partitions; wherein, based upon said relationship, a member of the admin partition has access rights to the first and second data partitions. ### Claim 2 (depends on 1) The method of claim 1, wherein the storing the relationship between the admin partition and the first and second data partitions comprises: associating the first P_Key with the second P_Key within the fabric manager database; and associating the first P_Key with the third P_Key within the fabric manager database. ### Claim 3 (depends on 2) The method of claim 2, further comprising: adding a first fabric resource to the first data partition, wherein the adding comprises assigning the second P_Key to the first fabric resource; wherein the first fabric resource comprises a first identifier. ### Claim 4 (depends on 3) The method of claim 3, further comprising: adding a second fabric resource to the second data partition, wherein the adding comprises assigning the third P_Key to the second fabric resource; wherein the second fabric resource comprises a second identifier. ### Claim 5 (depends on 4) The method of claim 4, further comprising: receiving, at a graphical user interface of the fabric manager, an instruction to make the first fabric resource a member of the admin partition; and creating, within the fabric manager database, an association between the first identifier and the first P_Key. ### Claim 6 (depends on 5) The method of claim 5, wherein, based on said association between the first identifier and the first P_Key, the first fabric resource has access rights within the second data partition. ### Claim 7 (depends on 5) The method of claim 5, wherein, based on said association between the first identifier and the first P_Key, the first fabric resource has access rights to the second fabric resource. ### Claim 8 A system of correlating fabric-level group membership with subnet-level group membership within a network fabric, comprising: a computer including one or more microprocessors; a fabric manager within the network fabric; and a fabric manager database associated with the fabric manager; wherein a resource domain is created within the network fabric, wherein the resource domain is a logical grouping of fabric resources; wherein a first partition key (P_Key) of a plurality of P_Keys is assigned to an admin partition in a subnet of the network fabric; wherein a second P_Key is assigned to a first data partition within the resource domain; wherein a third P_Key is assigned to a second data partition within the resource domain; wherein a relationship between the admin partition and the first and second data partitions is stored within fabric manager database;
