EXHIBIT C-1
`U.S. Patent No. 5,018,060 (“Gelb ’060”)
`
`Microsoft contends that the asserted claims of the ’132 Patent are invalid as anticipated or obvious by U.S. Patent No. 5,018,060
`(“Gelb ’060”) prior art reference under various subsections of 35 U.S.C. § 102 and in view of other prior art references under 35
`U.S.C. § 103 as set forth in Microsoft’s invalidity contentions.
`
`As Gelb ’060 was filed on January 26, 1989, and issued on May 21, 1991, Microsoft contends that it is prior art to the ’132 Patent
`under at least pre-AIA 35 U.S.C. § 102(b).
`
`Patent No. 8,671,132
`Claim 1
`1[Pre] A policy-based
`data management system
`comprising:
`
`Gelb ’060
`
`To the extent the preamble is limiting, Gelb ’060 discloses a policy-based data management system.
`Specifically, Gelb ’060 discloses a data storage and management system. For example, Gelb ’060
`states:
`
`“This invention relates to computer-controlled peripheral data storage and more particularly to the
`global management of data storage for provided transparent isolation of the peripheral data storage
`characteristics from application programs using the peripheral data storage.” Gelb ’060 at 1:9-14.
`
`“Units of data (data sets, data bases, etc.) are allocated data storage space in a data storage system
`based on implicit analysis of the unit of data. A plurality of data classes, each defining predetermined
`characteristics of diverse units of data, are established for the data storage system. A plurality of
`storage classes, each defining predetermined sets of storage performance and availability requirements
`are established for the data storage system. A plurality of management classes, each defining
`respective diverse sets of life cycle attributes for units of data are established for the data storage
`system. A plurality of storage groups, each defining diverse predetermined performance device and
`management available in the data storage system but independently of the individual storage devices of
`the data storage system are established. The devices are selectively assigned to different ones of the
`established storage groups. Each received spaced allocation requested has its parameters (source, type
`of data, etc.) matched with the data, storage and management classes for assignment of one each of
`those classes to the unit of data related to the allocation request. A storage group is also assigned. The
`matching of the different classes and group are independent of one another. Allocation is based upon
`the resulting class and group selection.” Gelb ’060 at Abstract.

`Claim 1
`

`
`“In accordance with the present invention, a plurality of data related classes are defined. Such classes
`are defined independent of each other. The classes are set up so as to enable a host processor to
`respond to data set parameters to implicitly select data storage units which can achieve the desired
`system operations for satisfying the data set parameters. The data set parameters are preferably
`implicitly derived from data set naming which are governed by data set naming conventions and
`standards explicitly unrelated to peripheral data storage parameters.” Gelb ’060 at 4:14-24.
`
`“The interactive relationship between a host processor 10 and an operator (Storage Administrator)
`includes terminal 13 and a terminal support program in such host processor 10. A preferred interactive
`system in setting up the classes and groups is the IBM Interactive System Management Facility
`(ISMF) which is a part of the IBM Data Facility Product (DFP). ISMF enables the steps illustrated in
`FIGS. 2 and 3 to be easily performed. In view of the plethora of interactive programs readily available,
`the internal details of such programs are not repeated here. The description herein discloses to one of
`ordinary skill how to implement the present invention. ISMF is menu driven having the following
`menu set up for establishing, inter alia, the classes, storage groups and ACS routines of the illustrated
`embodiment.” Gelb ’060 at 6:8-22.
`
`To the extent that it is argued that Gelb ’060 does not disclose all or part of this limitation, it would
`have been at least obvious to combine it with any other reference disclosing this limitation as
`explained in Microsoft’s Preliminary Invalidity Contention Cover Pleading.
`Gelb ’060 discloses a policy set comprising at least one service class rule. Specifically, Gelb ’060
`discloses a policy set executed by the ACS routines to select data class, management class, and storage
`class for files. For example, Gelb ’060 states:
`
`“In accordance with the present invention, a plurality of data related classes are defined. Such classes
`are defined independent of each other. The classes are set up so as to enable a host processor to
`respond to data set parameters to implicitly select data storage units which can achieve the desired
`system operations for satisfying the data set parameters. The data set parameters are preferably
`implicitly derived from data set naming which are governed by data set naming conventions and
`standards explicitly unrelated to peripheral data storage parameters.” Gelb ’060 at 4:14-24.

`
`“A data class specifies data set logical attributes, such as data set type, record length, data storage
`space requirements in terms of logical bytes not in terms of physical storage space requirements,
`expiration and retention dates for the data set and any Virtual Storage Access Method (VSAM) data set
`options. Just the data class by itself will simplify data set allocation (eg JCL DD statements are
`simplified), help introduce allocations standards and can be used with later defined classes in
`accordance with the present invention or can be used independently with increased isolation of the
`application programmer from the peripheral data storage system, as will become apparent.” Gelb ’060
`at 6:43-56.
`
`“Each management class relates to life cycle controls for a data set. Each specifies space, availability
`and retention management requirements. These specifications include migration from a high or rapid
`access level of a data storage hierarchy to lower levels or slower accesses, expiration and retention
`dates and limits, backup frequency (zero means no backup), retention of backup copies, generation
`data group (GDG) and set processing options (each GDG is a version of data, each time a data set is
`updated it is a candidate to become a new version of that data--i.e. a next generation of the data) and
`partial release options. Partial release means an unused portion of the data storage may be released, i.e.
`returned to a free or available space list for the volume. The description below describes a set of
`management classes defined via ISMF and which are suitable for practicing the present invention.”
`Gelb ’060 at 8:65-9:13.
`
`“Each storage class sets forth its own set of storage services in device independent terms. Such
`services include random access specifications, sequential access specifications, guaranteed space (i.e.
`pre-allocation of data storage space before any attempted storage of data in the peripheral data storage
`system), etc. From the above listed terms, it is seen that the requirements are separate from device
`capabilities.” Gelb ’060 at 7:56-64.

`selection, this ACS routine compares the information in DATACLAS 80 with the parameters (not
`shown) received with the data set, such as in the data set name (DSN). A predetermined comparison of
`the DATACLAS information and the received parameters, such as predetermined identities (no
`limitation thereto intended) causes the DATA CLASS ACS ROUTINE to select one of the above
`enumerated DATACLAS's. Upon selection of a data class, the second step 142 selects a storage class.
`The program for the machine-implemented selection is shown in the table entitled "STORAGE
`CLASS ACS ROUTINE", supra. One of the options in the storage class selection machine process, as
`indicated by arrow 143, is to assign the allocation to a "non-SMS managed" portion of the data
`processing system. That is, the storage management system (SMS) which uses the storage and
`management classes is not to manage the data set which is the subject of the current class selection
`request. This exclusion process is at the comment "define non SMS-managed data sets" within the
`listing STORAGE CLASS ACS ROUTINE. In the example, the system data sets (SYS.**) having a
`DSN including the exclusion parameter for being directed away from the controls of the present
`invention is based upon parsing the DSN. Therefore, data classes are selectable for data sets to be
`managed by operation of the present invention or with other types of controls.” Gelb ’060 at 18:47-
`19:15.
`
`“The logical relationships of application programming to the controls effected by the present invention
`are illustrated in simplified form in FIG. 4. All items shown in FIG. 4 excepting peripheral data storage
`12 are in a host processor 10. A large plurality of application programs 30 execute on the host
`processor 10. Software connections to the peripheral control programs 31 are provided in the usual
`manner. Data Facility Product (DFP) 32 includes programming that implements the present invention.
`A portion of DFP 32 is ISMF 33, a terminal support programs referred to above for operating with
`terminal 13. Double-headed arrow 34 represents the connection to one or more terminals 13. Data
`mover program 35 actually causes data movement between main memory (not shown) of the most
`processor and peripheral data storage 12. IBM program DFDSS is such a data mover program. Data
`mover 35 operates with IOS (input output system) 37, a part of the operating system of host processor
`10, to effect transfer of data between the main memory (not shown) of the host processor 10 and the
`peripheral data storage 12 via input output channels 38. Coordination of such peripheral operations is

`
`Gelb ’060 discloses that the file evaluation module is further configured to automatically assign the file
`to a storage pool. Specifically, Gelb ’060 discloses software program configured to automatically
`assign the file to a storage group. For example, Gelb ’060 states:
`
`“In a machine-effected method of the invention, the data related classes include data classes which are
`based upon predetermined data set parameters for diverse types of data sets to be stored and retrieved
`from peripheral data storage, storage classes which include classification by predetermined
`performance and availability parameters for data sets which are to be members of various ones of the
`storage classes, storage group(s), which define the collections of peripheral data storage devices as to
`status, capacity, connectability etc, and management classes which respectively define the life cycle
`characteristics of the various data sets. The information from a storage class is used for selecting data
`storing volumes within one of the storage group(s) independently of any application program JCL
`statements. Also, the available free space in the data storing volumes and their respective current levels
`of activity are factors in the selection of the storage group volumes.” Gelb ’060 at 4:25-43.
`
`“Execution step 18, started by selecting 6 on the ISMF menu above, generates a definition for a storage
`group. Each storage group identifies a group of data storage volumes, much like a volume pool; each
`such group can be similar to the storage groups described by Clifton et al, supra. Each storage group
`has its own volume management requirements such as space allocation thresholds (xx,yy) wherein xx
`is a high threshold value--if the volume fills to this threshold, then the data processing system initiates
`a migration of data from the primary or level zero volume until the xx is no longer exceeded. Such
`migration is known and can be effected by the IBM program product DFHSM. yy is a low threshold
`value at which threshold the above-mentioned migration to a data storing volume at a lower level of
`the data storage hierarchy stops. Such migration implicitly includes the operations of moving data sets
`from the volume, but also includes releasing the space once occupied by a migrated (moved) data set

`and deleting data sets in the volume that need not be migrated. The IBM program product DFHSM
`migrates, backs up and recovers data sets. A storage group is only selected for a data set to receive a
`peripheral storage allocation by program means; that is no storage group is selectable by a user or
`application programmer as provided for in Clifton et al.” Gelb ’060 at 10:14-39.
`
`“The defined storage groups for a suitable set to practice the present invention are next defined, no
`limitation thereto intended. It is assumed that selection 6 of the above-indicated ISMF menu has been
`made. Four types of storage groups are defined, PRIMARY for non-data-base data sets, LARGE for
`large, non-data-base data sets, DATABASE for data base data sets and VIO for small temporary data
`sets. Unless otherwise selected, the defaults for all of the four storage groups are: auto-migration is
`enabled, automatic backup is enabled, no automatic dump is permitted, there are no migration
`thresholds set and a dump class is left blank.
`
`The PRIMARY storage group is a pool of data sets. The PRIMARY storage group definition has a list
`of data storing volumes in the storage group, a list of systems, migration threshold is set at 90,80,
`automatic dump is enabled and dumping occurs on Sunday (Dump class =SUNDAY). The LARGE
`storage group also is a pool of data sets. The definition of the LARGE storage group lists storage
`volumes selectable for storing large data sets (this list has volumes different from the PRIMARY class
`volumes, no limitation thereto intended), indicates the system (may be the same system as indicated in
`other storage groups), automatic migration and backup are enabled, the migration threshold is set for
`50,40, automatic dump is permitted in dump class SUNDAY. The storage group DATABASE (a pool
`type storage group) definition lists data storing volumes different from the lists in the storage groups
`PRIMARY and LARGE, no limitation thereto intended, it may indicate the same system, automatic
`migration is enabled while automatic backup and dump are disabled. A migration threshold of 90,80 is
`indicated. The storage group VIO is for virtual I/O with a maximum size of 1024 bytes, having a unit
`name of 3380 and identifies the same system as identified in the other three storage groups.” Gelb

`“The classes and groups are first defined using interactive means by a so-called Storage Administrator.
`The defined classes and groups are assembled into control tables used to implicitly select data devices
`based on logical level specifications about the data set to receive an allocation of peripheral data
`storage space. In a preferred sequence of machine effected device selection, the data class is first
`selected, then a storage class is selected followed by selection of a management class. The selection of
`the three classes are then combined to select a storage group which best fits the parameters set forth in
`the three selected classes. The selection of classes for any data set or data base depends not only on the
`class definitions, but also on the logic used in the automatic class selection processing. In all cases, the
`Storage Administrator (usually a person) has total control over the volume and class selection criteria;
`the application programmer need not be concerned with such definitions. Once a storage group has
`been selected, allocation of data storing space of a volume which is a member of the storage group
`may proceed asynchronously with respect to automatic class selection.” Gelb ’060 at 4:57-5:11.

`
`“In a machine-effected method of the invention, the data related classes include data classes which are
`based upon predetermined data set parameters for diverse types of data sets to be stored and retrieved
`from peripheral data storage, storage classes which include classification by predetermined
`performance and availability parameters for data sets which are to be members of various ones of the
`storage classes, storage group(s), which define the collections of peripheral data storage devices as to
`status, capacity, connectability etc, and management classes which respectively define the life cycle
`characteristics of the various data sets. The information from a storage class is used for selecting data
`storing volumes within one of the storage group(s) independently of any application program JCL
`statements. Also, the available free space in the data storing volumes and their respective current levels
`of activity are factors in the selection of the storage group volumes.” Gelb ’060 at 4:25-43.
`
`“Execution step 18, started by selecting 6 on the ISMF menu above, generates a definition for a storage
`group. Each storage group identifies a group of data storage volumes, much like a volume pool; each
`such group can be similar to the storage groups described by Clifton et al, supra. Each storage group
`has its own volume management requirements such as space allocation thresholds (xx,yy) wherein xx
`is a high threshold value--if the volume fills to this threshold, then the data processing system initiates
`a migration of data from the primary or level zero volume until the xx is no longer exceeded. Such
`migration is known and can be effected by the IBM program product DFHSM. yy is a low threshold
`value at which threshold the above-mentioned migration to a data storing volume at a lower level of
`the data storage hierarchy stops. Such migration implicitly includes the operations of moving data sets
`from the volume, but also includes releasing the space once occupied by a migrated (moved) data set
`and deleting data sets in the volume that need not be migrated. The IBM program product DFHSM
`migrates, backs up and recovers data sets. A storage group is only selected for a data set to receive a
`peripheral storage allocation by program means; that is no storage group is selectable by a user or
`application programmer as provided for in Clifton et al.” Gelb ’060 at 10:14-39.
`
`“The defined storage groups for a suitable set to practice the present invention are next defined, no
`limitation thereto intended. It is assumed that selection 6 of the above-indicated ISMF menu has been
`made. Four types of storage groups are defined, PRIMARY for non-data-base data sets, LARGE for
`large, non-data-base data sets, DATABASE for data base data sets and VIO for small temporary data
`sets. Unless otherwise selected, the defaults for all of the four storage groups are: auto-migration is

`enabled, automatic backup is enabled, no automatic dump is permitted, there are no migration
`thresholds set and a dump class is left blank.
`
`The PRIMARY storage group is a pool of data sets. The PRIMARY storage group definition has a list
`of data storing volumes in the storage group, a list of systems, migration threshold is set at 90,80,
`automatic dump is enabled and dumping occurs on Sunday (Dump class =SUNDAY). The LARGE
`storage group also is a pool of data sets. The definition of the LARGE storage group lists storage
`volumes selectable for storing large data sets (this list has volumes different from the PRIMARY class
`volumes, no limitation thereto intended), indicates the system (may be the same system as indicated in
`other storage groups), automatic migration and backup are enabled, the migration threshold is set for
`50,40, automatic dump is permitted in dump class SUNDAY. The storage group DATABASE (a pool
`type storage group) definition lists data storing volumes different from the lists in the storage groups
