摘要： Computer systems, virtual storage systems, and virtual storage system operational methods are described. According to one aspect, a computer system includes a virtual storage system including a physical storage space, a virtual storage space, and a non-guaranteed available capacity utilized to generate a non-guaranteed snapshot volumes of virtual storage volumes of the virtual storage space, wherein the virtual storage system is configured to monitor the non-guaranteed available capacity and to present a report regarding the non-guaranteed available capacity responsive to the monitoring and a host configured to execute an application wherein generation of a non-guaranteed snapshot volume of at least one of the virtual storage volumes is desired, to access the report to determine the non-guaranteed available capacity, and to issue a request to the virtual storage system to generate the at least one non-guaranteed snapshot volume of the at least one virtual storage volume responsive to the accessing.

摘要： Virtual storage systems and virtual storage system operational methods are described. According to one aspect, a virtual storage system includes a physical storage space configured to store data, a virtual storage space adapted to provide a representation of data stored within the physical storage space to a host, a memory configured to store a plurality of pointers utilized to implement addressing intermediate the physical storage space and the virtual storage space, and a controller configured to extract selected ones of the pointers from the memory and to provide the selected pointers in another storage location different than the memory at a first moment in time and to extract the selected pointers from the another storage location and to provide the selected pointers in the memory at a second moment in time subsequent to the first moment in time.
