  • System and method for object management
    Patent number: 9207881
    Abstract: A method, computer program product, and computing system for defining a first virtual object, wherein the first virtual object includes a first ready state indicator. At least a second virtual object is defined, wherein the at least a second virtual object includes at least a second ready state indicator. The first virtual object and the at least a second virtual object are grouped within a group virtual object.

  • Managing properties collection
    Patent number: 8972340
    Abstract: A method is used in managing properties collection. Storage objects for which properties information is to be refreshed are determined. A bulk request for properties information from file systems corresponding to the storage objects is generated and is issued to the file systems. Based on a response to the bulk request, a blocking transaction is used to update a model of the storage objects that is made available to management software.

  • Method of allowing point-in-time view of data on a disk
    Patent number: 7159085
    Abstract: A method allows point-in-time viewing of session data for multiple sessions being stored on a disk. Session bits are set for the session data in memory which points to the data at any particular point in time, and this can be done for multiple sessions. In order to make the session data persistent, separate session bits are stored in a portion of a disk reserved for such session bits. Thus, in the event of failure where session bits which are stored in volatile memory such as RAM, are lost, the duplicate copy set in the non-volatile memory can be used to recreate the session once the failure is corrected.

  • Method of allowing point-in-time view of data on a disk using a map on cache disk
    Patent number: 7155586
    Abstract: A method of creating point-in-time views of data on a disk involves initiating from a host at least one session of writing data to a disk. For each session, an entry is created and stored on an array on the disk. The sessions are assigned unique IDs to each, and provide indications where data for a particular session may be found on the disk.
