Abstract

A method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions. The programming instructions are operable to determine one or more optimal mappings between a server layer and a storage layer through a network layer based on performance metrics of one or more ports of at least one of the server layer, the storage layer and the network layer.

Claims

1. A method implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions operable to determine one or more mappings between a server layer and a storage layer through a network layer based on one or more security constraints.

2. The method of claim 1, wherein the one or more security constraints are multi-tenancy security constraints.

3. The method of claim 1, wherein the determining the one or more mappings comprises determining at least one hard zone.

4. The method of claim 3, wherein the at least one hard zone is in the network layer.

5. The method of claim 3, wherein the determining the at least one hard zone comprises dynamically determining the at least one hard zone within the network layer.

6. The method of claim 3, wherein the at least one hard zone enables a port of a server to see a port of a storage system.

7. The method of claim 3, wherein the at least one hard zone directs traffic between two or more ports of a switch in the network layer.

8. The method of claim 3, wherein the programming instructions are further operable to configure the at least one hard zone to prevent unauthorized access to at least one of the storage layer, the network layer and the server layer.

9. The method of claim 1, wherein the determining the one or more mappings comprises determining at least one masking.

10. The method of claim 9, wherein the at least one masking indicates a server of the server layer permitted to connect to a storage system of the storage layer.
