Apparatus and method for using storage domains for controlling data in storage area networks
First Claim
1. A method for managing a storage area network (SAN), the method comprising:
- defining storage domains respectively having associated configurable storage management properties that are separate from individual physical capabilities of physical storage resources available through the SAN, wherein a first set of storage management properties is associated with a first storage domain and a second set of storage management properties is associated with a second storage domain, with the first set of storage management properties being different from the second set of storage management properties;
accommodating the creation of logical volumes configurable for presentation to hosts through the SAN; and
allocating the logical volumes to hosts in the context of the storage domains, wherein allocating a logical volume to a host in the context of the first storage domain entails the provision of storage resources according to the first set of storage management properties and allocating a logical volume to a host in the context of the second storage domain entails the provision of storage resources according to the second set of storage management properties, wherein presentation of logical volumes to hosts accommodates storage resource access by hosts without requiring hosts to be configured according to the requirements of the physical storage resources, and wherein said allocation of logical volumes to hosts in the context of the storage domains entails provision of storage resources according to the respective storage management properties of the storage domains even though the logical volumes are created from physical storage resources in common.

Abstract
Storage domains respectively have associated configurable storage management properties that are separate from individual physical capabilities of physical storage resources available through a SAN. Logical volumes are created and allocated to hosts in the context of the storage domains. The presentation of such logical volumes to hosts accommodates storage resource access by hosts without requiring the hosts to be configured according to the requirements of the physical storage resources. Furthermore, allocation of logical volumes to hosts in the context of the storage domains entails provision of storage resources according to the respective storage management properties of the storage domains even though the logical volumes are created from physical storage resources in common.

16. A storage area network (SAN) that accommodates presentation of logical volumes to hosts and associates access to storage with configurable storage management properties defined by a storage domain, the storage area network comprising:
-
storage domains respectively defined to have associated configurable storage management properties that are separate from individual physical capabilities of physical storage resources available through the SAN, wherein a first set of storage management properties is associated with a first storage domain and a second set of storage management properties is associated with a second storage domain, with the first set of storage management properties being different from the second set of storage management properties;
logical volumes configurable for presentation to hosts through the SAN; and
means for allocating the logical volumes to hosts in the context of the storage domains, wherein allocating a logical volume to a host in the context of the first storage domain entails the provision of storage resources according to the first set of storage management properties and allocating a logical volume to a host in the context of the second storage domain entails the provision of storage resources according to the second set of storage management properties, wherein presentation of logical volumes to hosts accommodates storage resource access by hosts without requiring hosts to be configured according to the requirements of the physical storage resources, and wherein said allocation of logical volumes to hosts in the context of the storage domains entails provision of storage resources according to the respective storage management properties of the storage domains even though the logical volumes are created from physical storage resources in common. - View Dependent Claims (17, 18, 19, 20)
