OBJECT STORAGE SYSTEM
First Claim
1. A method of creating a logical storage volume from a storage system that includes physical data storage units (DSUs), the method comprising:
- creating a logical storage container having an address space that maps to storage locations of the DSUs; and
creating a plurality of logical storage volumes, each having an address space that maps to the address space of the logical storage container, and each of which is a storage object to which IOs are directed.

Abstract
The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. Logical storage volumes are created from a logical storage container having an address space that maps to storage locations of the physical data storage units. Each of the logical storage volumes so created has an address space that maps to the address space of the logical storage container. A logical storage container may span more than one storage system and logical storage volumes of different customers can be provisioned from the same logical storage container with appropriate security settings.
