Intelligent storage provisioning within a clustered computing environment

A system for storage provisioning in a clustered computing environment, comprising:

• a bus;
• a processor coupled to the bus;
• and
• a memory medium coupled to the bus, the memory medium comprising instructions to:
• determine a set of storage area network volume controllers (SVCs) within the clustered computing environment that is accessible from a host submitting a request for access to storage;
• determine a set of managed disk (mdisk) groups corresponding to the set of SVCs that are candidates for fulfilling the request;
• perform a first filtering operation on the set of mdisk groups based on available space therein and a set of user preferences;
• if more than one mdisk group corresponding to the set of SVCs that are candidates remains after the first filtering operation, perform a second filtering operation on the set of mdisk groups based on a set of performance characteristics, and identify the one mdisk group from the set of mdisk groups based on the second filtering to which to provision the request for access to storage;
• if one mdisk group remains after the first filtering operation, identifying the one mdisk group from the set of mdisk groups based on the first filtering operation to which to provision the request for access to storage.

A computer program product for storage provisioning in a clustered computing environment, the computer program product comprising a non-transitory computer readable storage media, and program instructions stored on the non-transitory computer readable storage media, to:

• determine a set of storage area network volume controllers (SVCs) within the clustered computing environment that is accessible from a host submitting a request for access to storage;
• determine a set of managed disk (mdisk) groups corresponding to the set of SVCs that are candidates for fulfilling the request;
• perform a first filtering operation on the set of mdisk groups based on available space therein and a set of user preferences;
• if more than one mdisk group corresponding to the set of SVCs that are candidates remains after the first filtering operation, perform a second filtering operation on the set of mdisk groups based on a set of performance characteristics, and identify the one mdisk group from the set of mdisk groups based on the second filtering to which to provision the request for access to storage;
• if one mdisk group remains after the first filtering operation, identifying the one mdisk group from the set of mdisk groups based on the first filtering operation to which to provision the request for access to storage.
