1. A method for storage provisioning in a clustered computing environment, comprising: determining 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; determining a set of managed disk (mdisk) groups corresponding to the set of SVCs that are candidates for fulfilling the request; filtering the set of mdisk groups based on available space therein, a set of user preferences, and a set of performance characteristics; and identifying a particular mdisk group from the set of mdisk groups based on the filtering, the particular mdisk group being identified to fulfill the request for access to storage; and provisioning the request for access to storage to the particular mdisk group.
