Acquisition and expansion of storage area network interoperation relationships

## Abstract

A plurality of components of a storage area network is grouped into a plurality of component groups, wherein a component group includes one or more of the plurality of components of the storage area network. A group relationship data structure provides relationships among one or more of the plurality of component groups, wherein a relationship indicates a supported configuration of the storage area network.

## Background
BACKGROUND
1. Field
The disclosure relates to a method, system, and article of manufacture for the acquisition and expansion of storage area network interoperation relationships.
2. Background
A storage area network, also referred to as a SAN, may be comprised of many components, such as, servers, clients, operating systems, storage devices, switches, host bus adapters, etc. Furthermore, components may be added or removed from such storage area networks. Certain components may not interoperate, i.e., function, with certain other components of the storage area network. For example, a server of type A may interoperate only with an operating system of type B but may not interoperate with an operating system of type C.
It may be desirable for certain users to be aware of the interoperation capabilities of the components that may be included in a storage area network. Maintenance of such storage area network interoperation capabilities may be complex, error prone and labor intensive. Numerous combinations of storage area network components are possible, wherein configuration exceptions and anomalies may occur.
Certain mechanisms may capture and document the interoperation capabilities among elements of a storage area network manually. For example, in certain solutions, supported configurations of components in a storage area network may be maintained in an online or printed manual, with many indications of exceptions being indicated in footnotes to the supported configurations.
SUMMARY OF THE PREFERRED EMBODIMENTS
Provided are a method, system, and article of manufacture wherein a plurality of components of a storage area network is grouped into a plurality of component groups, wherein a component group includes one or more of the plurality of components of the storage area network. A group relationship data structure provides relationships among one or more of the plurality of component groups, wherein a relationship indicates a supported configuration of the storage area network.
In additional embodiments, the relationships among the one or more of the plurality of components groups are fewer in number in comparison to all supported combinations of the plurality of components in the storage area network.
In further embodiments entries are stored in a storage area network interoperability database, based on the relationships provided in the group relationship data structure and the plurality of component groups, wherein generating the storage area network interoperability database based on the relationships provided in the group relationship data structure and the plurality of component groups is performed faster in comparison to generating the storage area network interoperability database based on storing entries corresponding to all supported combinations of the plurality of components in the storage area network to the storage area network interoperability database. In yet further embodiments, a new component is added to the storage area network, wherein characteristics of the new component for interoperability with other components of the storage area network are indicated. A group relationship generation application modifies the component groups and the relationships in the group relationship data structure, wherein the modified relationships indicate supported configurations of the storage area network.
In still further embodiments, at least one exception to an interoperability of at least one component of the storage area network is indicated. A group relationship generation application modifies the component groups and the relationships in the group relationship data structure, wherein the modified relationships indicate supported configurations of the storage area network.

DETAILED DESCRIPTION
In the following description, reference is made to the accompanying drawings which form a part hereof and which illustrate several embodiments. It is understood that other embodiments may be utilized and structural and operational changes may be made.
Certain embodiments provide for the grouping of various related components of a storage area network into groups, wherein the groups are referred to as component groups. The interoperation capabilities among components groups are maintained in a group relationship data structure by a group relationship generation application. The group relationship data structure and the component groups may be used to store entries in a storage area network interoperation database, wherein the storage area network interoperation database is used to respond to user or automated queries that request the interoperation capabilities of various individual components for the inclusion of components in the storage area network.
If supported configurations of components in the storage area network are generated without the formation of component groups, i.e., supported configurations are based on indicating the interoperability of individual components, then the loading time for entries of the storage area network interoperation database may be significantly more than that provided by certain embodiments in which the group relationship data structure and the component groups are used to load entries into the storage area network interoperation database.
Exemplary Embodiments
FIG. 1 illustrates a block diagram of a computing environment 100 that includes a computational platform 102. While FIG. 1 shows a single computational platform 102, in alternative embodiments a different number of computational platforms may be used to implement certain embodiments. For example, certain embodiments may be implemented in a distributed computing environment with a plurality of computational platforms collectively performing certain operations. The computational platform 102 may comprise any suitable computational platform, including those presently known in the art, such as, a server, a personal computer, a workstation, a mainframe, a midrange computer, a network appliance, a palm top computer, a telephony device, a blade computer, a hand held computer, etc.
The computational platform 102 includes a group relationship generation application 104 and a database generating application 106, that may also be referred to as a database generating/storing application because the database generating application 106 may store entries in a database to generate the database. In alternative embodiments, the operations performed by the group relationship generation application 104 and the database generating application 106 may be implemented by a single application or by more than two applications. The group relationship generation application 104 may be implemented differently in different exemplary embodiments, and in certain embodiments the group relationship generation application 104 may be a spreadsheet that takes inputs generated by a human expert based on the results of a series of tests that qualify SAN configurations.
The group relationship generation application 104 may group a set of related components into component groups 108 and may store the interoperation capabilities of the component groups in a group relationship data structure 110, wherein the group relationship data structure 110 may be implemented as a spreadsheet, a set of tuples, a text file, a database or via any other suitable data structure. The individual components included in the component groups 108 may be candidates for inclusion in a SAN.
The database generating application 106 may use the component groups 108 and the group relationship data structure 110 for creating, managing, entering and loading interoperation configurations into a SAN interoperation database 112, wherein the SAN interoperation database 112 may be used to respond to queries from a user, wherein the queries are related to the interoperation of components with a potential for inclusion in the SAN.
Therefore, FIG. 1 illustrates certain embodiments in which a group relationship generation application 104 stores groups of components in component groups 108 and generates the relationship between individual component groups for storage in the group relationship data structure 110. The database generating application 106 loads entries into the SAN interoperation database 112 based on information included in the component groups 108 and the group relationship data structure 100.
FIG. 2 illustrates exemplary components 200 of a SAN, an exemplary group relationship data structure 110 (shown previously in FIG. 1), and exemplary component groups 108 (shown previously in FIG. 1), in accordance with certain embodiments.
The exemplary components 200 illustrated in FIG. 2 may include:
(i) Exemplary servers illustrated as server S1 202 and server S2 204;
(ii) Exemplary operating systems illustrated as operating system OS1 206 and operating system OS2 208;
(iii) Exemplary host bus adapters illustrated as host bus adapter HBA1 210 and host bus adapter HBA2 212; and
(iv) Exemplary SAN switches illustrated as SAN switch SS1 214, SAN switch SS2 216, and SAN switch SS3 218.
Other types of exemplary components may be found in alternative embodiments. Additionally the number of exemplary components for each type may be fewer or greater in number than the exemplary components 200 shown in FIG. 2.
The exemplary group relationship data structure 110 shown in FIG. 2 (and shown previously in FIG. 1) may include one or more exemplary group relationships, such as a first group relationship 220 and other group relationships 222. The exemplary first group relationship 220 may include a server group SG1 224, an operating system group OSG1 226, a host bus adapter group HBAG1 228 and a SAN switch group SSG1 230. The group relationship data structure 110 indicates that any component of server group SG1 224 may be coupled to any component of the operating system group OSG1 226, and may be coupled to any component of the host bus adapter group HBAG1 228, and may be coupled to any component of the SAN switch group SSG1 230 for interoperability. SAN configurations that include components in conformity with the first group relationship 220 may be supported by a vendor or support provider for the SAN.
FIG. 2 also illustrates the components in each of the component groups shown in the first group relationship 220 of the group relationship data structure 110. For example, server group SG1 includes server S1 202 and server S2 204, operating system group OSG1 226 includes operating system OS1 206 and operating system OS2 208, host bus adapter group HBAG1 228 includes host bus adapter HBA1 210 and host bus adapter HBA2 212, and SAN switch group SSG1 230 includes the SAN switch SS1 214 and SAN switch SS2 216. Other groups 232 may also be included in the exemplary component groups 108.
FIG. 3 illustrates how a more compact representation 300 of interoperability relationships is obtained by maintaining group relationships 220 in accordance with certain embodiments.
It can be seen from FIG. 3 that all the possible combinations 302 of the components of the groups included in the first group relationship 220 greatly exceed the single relationship maintained among the server group SG1 224, operating system group OSG1 226, host bus adapter group HBAG1 228 and SAN switch group SSG1 230. Therefore, if the group relationship data structure 110 (shown previously in FIGS. 1 and 2) that includes the first group relationship 220 is used with the component groups 108 (shown previously in FIGS. 1 and 2) then the loading of entries into the SAN interoperation database 112 may be faster than if all possible combinations 302 of the components were used for the loading of entries into the SAN interoperation database 112. In certain exemplary systems, the combinations 302 may exceed a hundreds of thousands, millions, or potentially over tens of millions of entries and storing entries corresponding such a large number of combinations may be extremely time consuming in comparison to storing entries corresponding to the relationships 220, 222 (shown previously in FIG. 2) of the group relationship data structure 110 (shown previously in FIGS. 1 and 2) and the component groups 108 (shown previously in FIGS. 1 and 2).
FIG. 4 illustrates the effect of the potential addition 400 of a new component to a SAN, in accordance with certain embodiments. In FIG. 4, the newly added component 402 is shown as server S3 404. In certain embodiments, when server S3 404 is added then the server group SG1 224 (shown in FIG. 2) that had two components server S1 202 and server S2 204 is updated to include the server S3 404 as shown in the updated server group 406. The exemplary first group relationship 220 does not undergo any change (although for ease of illustration the server group SG1 is referenced with reference numeral 408 in FIG. 4). Therefore, in certain embodiments the modifications needed to for adding new components to the SAN may be far less in comparison to the situation in which all valid combinations for interoperability among individual components is explicitly listed. Even in embodiments where the group relationships may have to be modified, the modifications may still be far less in comparison to the situation in which all valid combinations for interoperability among individual components are explicitly listed.
FIG. 5 illustrates the handling of exceptions 500 to generally supported configurations, in accordance with certain embodiments. The exceptions 502 to generally supported configurations are shown as follows:
(i) Operating System, OS2 208 (shown previously in FIG. 2), is not supported on Server, S1 202 (shown previously in FIG. 2); and
(ii) SAN switch, SS1 214 (shown previously in FIG. 2), is not supported on Server, S2 204 (shown previously in FIG. 2).
In certain embodiments shown in FIG. 5 the component groups and group relationships may need to be modified and/or extended. For the exemplary handling of exceptions 502 in the configuration shown in FIG. 2, the operations may include:
(i) no change to the first group relationship (represented by reference numeral 504 in FIG. 5 and by reference numeral 220 in FIG. 2), although the groups 510, 512, 514, 516 included in the first group relationship 504 of FIG. 5 may be different from that included in the first group relationship 220 of FIG. 2;

(ii) Addition of a second group relationship 506 with server group SG2 518, operating system group OSG2 520, host bus adapter group HBAG1 522 and SAN switch group SSG2 524;

(iii) Changes to the component groups to generate modified component groups 508, wherein the representations shown in the modified components group 508 indicate the component groups to the left (e.g. SG1, SG2, etc.) of the symbol “→” and the corresponding components enclosed within parenthesis to the right of the symbol “→”. For example, component group OSG1 is shown as having component OS1 in the modified component groups 508.

The fully expanded configuration 526 corresponding to the group relationships 504, 506 are also shown in FIG. 5. Certain entries have been shown with a strikethrough mark in the fully expanded configuration 526 to indicate that these entries that were previously present in the SAN configuration shown in FIG. 2 are not possible in accordance with the exceptions 502.
Certain embodiments do not need footnotes or additional statements to indicate exceptions to generally supported configurations in the SAN. The group relationship entries 504, 506 are fewer than the fully expanded configuration 526 and therefore in certain embodiments fewer entries may need to be stored in the SAN interoperation database 112 in comparison to the situation in which the fully expanded configuration 526 is stored in the SAN interoperation database 112.
FIG. 6 illustrates first operations, in accordance with certain embodiments. The operations illustrated in FIG. 6 may be implemented by the group relationship generation application 104 and the database generating application 106 of the computational platform 102 in the computing environment 100.
Control starts at block 600 in which data on interoperability of SAN components is collected. The group relationship generation application 104 (shown previously in at least FIG. 1) generates (at block 602) the group relationship data structure 110 (shown previously in at least FIG. 1) and the corresponding component groups 108 (shown previously in at least FIG. 1).
Control proceeds to block 604, where a determination is made as to whether new components (e.g., new server S3 404 shown in FIG. 4) or new exceptions (e.g., exceptions 502 shown in FIG. 5) are indicated in updated interoperability data. If so, then the group relationship generation application 104 updates (at block 606) the group relationship data structure 110 and the corresponding component groups 108. Then the database generating/storing application 106 stores (at block 608) entries in the SAN interoperability database 112 based on the group relationship data structure 110 and the corresponding component groups 108. From block 604 control proceeds to block 608 if no new components or new exceptions are indicated in the updated interoperability data.
FIG. 7 illustrates second operations, in accordance with certain embodiments. The operations illustrated in FIG. 7 may be implemented by the group relationship generation application 104 and the database generating application 106 of the computational platform 102 in the computing environment 100.
Control starts at block 700, in which a grouping is performed of a plurality of components (e.g., exemplary components 200 of FIG. 2) of a storage area network into a plurality of component groups (e.g., exemplary component groups 108 of FIGS. 1 and 2), wherein a component group includes one or more of the plurality of components of the storage area network. A group relationship data structure 110 (shown previously in at least FIGS. 1 and 2) is generated to provide (at block 702) an indication of relationships (e.g., relationships 220, 222 shown in FIG. 2) among one or more of the plurality of component groups, wherein a relationship indicates a supported configuration of the storage area network.
Control proceeds to block 704, wherein entries are stored in a storage area network interoperability database 112 (shown previously in FIG. 1), based on the relationships provided in the group relationship data structure 110 and the plurality of component groups 108. An optional addition (at block 706) is made of a new component to the storage area network, wherein characteristics of the new component (e.g., exemplary server S3 404 shown previously in FIG. 4) for interoperability with other components of the storage area network are indicated. Additionally an optional indication is made (at block 708) of at least one exception (such as exceptions 502 shown previously in FIG. 5) to the interoperability of at least two components of the storage area network.
Control proceeds to block 710, wherein the group relationship generation application 104 (shown previously in at least FIG. 1) modifies the component groups 108 and the relationships in the group relationship data structure 110, and wherein the modified relationships indicate supported configurations of the storage area network. Control may return to block 704 from block 710.
Therefore, certain embodiments allow for the recognition and optimization for patterns where storage area configurations share common support characteristics. At the same time certain embodiments may efficiently provide for a number of exceptions in support characteristics. Furthermore, certain embodiments may group together all components that share similar support characteristics and may be able to create unique groups that have different support characteristics.
Certain embodiments allow for the collection and communication of the interoperability of various components in a storage area network, and may allow users to determine that a given configuration of components in a storage area network is supported by a vendor. Searching and loading of entries are reduced for entering into a database in comparison to situations where all potential combinations are stored in the database.
