Appeal No. 2002-1576
Application No. 09/426,516
BACKGROUND
The Appellants’ invention relates to the management of virtual tape volumes
using data page atomic units. An understanding of the invention can be derived from a
reading of exemplary claim 11, which is reproduced below.
11. An intelligent data storage manager operational in a virtual data
storage system that uses a plurality of high and low performance data
storage elements to store data thereon for at least one host processor
connected to the virtual data storage system, the intelligent data storage
manager comprising:
a host interface for receiving a virtual tape volume having a plurality
of virtual tape blocks from a host processor; and
a controller for sequentially segmenting the virtual tape volume into
data pages, wherein each data page includes at least one virtual tape
block of the virtual tape volume, wherein the controller generates a meta
data page associated with the virtual tape volume to map the data pages
to the respective virtual tape blocks of the virtual tape volume, wherein the
controller uses the meta data page to selectively store the data pages
onto the high and low performance data storage elements;
wherein each of the high and low performance data storage
elements has a partitioning configuration, wherein the amount of the at
least one virtual tape block included by each data page is a function of the
partitioning configuration of at least one of the high and low performance
data storage elements.
The prior art reference of record relied upon by the examiner in rejecting the
appealed claims is:
