## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present patent document is a continuation of U.S. patent application Ser. No. 13/406,847, filed Feb. 28, 2012, entitled “RECONFIGURING INTERRELATIONSHIPS BETWEEN COMPONENTS OF VIRTUAL COMPUTING NETWORKS”, the disclosure of which is incorporated herein by reference.


TECHNICAL FIELD
In general, embodiments of the present invention relate to the reconfiguration of components of virtual computing networks. Specifically, embodiments of the present invention relate to the reconfiguration of interrelationships between components of virtual computing networks (e.g., a grid computing network, a local area network (LAN), a cloud computing network, etc.).
BACKGROUND
Generating an understanding of interactions between components of virtual computing networks as the components relate to physical systems and virtual machines may be a complex matter. Generally, network routing tables and data may reside on networking devices, and information regarding virtual machines may reside inside a virtualization engine. Challenges may exist, however, in that this information may be stored in disparate locations and may not be easily correlated. In addition, both switches and servers may utilize virtualized resources. When a physical failure occurs, it may be difficult to correlate the virtual resources in both the servers and the switches with physical resources to determine an appropriate corrective action.

As mentioned above, embodiments of the present invention relate to an approach for reconfiguring interrelationships between components of virtual computing networks (e.g., a grid computing network, a local area network (LAN), a cloud computing network, etc.). In a typical embodiment, a set of information pertaining to a set of components associated with a virtual computing network is received in a computer memory medium or the like. In general, the set of components may comprise a set of servers, a set of ports, a set of switches, a set of virtual machines (VMs), etc. The set of information may describe a set of interrelationships between the set of components. Regardless, based on the set of information, a graphical representation (e.g., hierarchical tree) depicting the set of interrelationships between the set of components is generated. When a failure in the virtual computing network is detected, at least one of the set of interrelationships between the set of components is reconfigured based on the graphical representation and the set of rules to address the failure.
Referring now to FIG. 1, a schematic of an example of a computing node is shown. Computing node 10 is only one example of a suitable computing node and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein. Regardless, computing node 10 is capable of being implemented and/or performing any of the functionality set forth hereinabove.
In computing node 10, there is a computer system/server 12, which is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with computer system/server 12 include, but are not limited to, personal computer systems, server computer systems, thin clients, thick clients, hand-held or laptop devices, mobile devices, global positioning systems (GPS), GPS-enable devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputer systems, mainframe computer systems, and distributed computing environments that include any of the above systems or devices, and the like.
Computer system/server 12 may be described in the general context of computer system-executable instructions, such as program modules, being executed by a computer system. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on, that perform particular tasks or implement particular abstract data types. Computer system/server 12 may be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices.
As shown in FIG. 1, computer system/server 12 in computing node 10 is shown in the form of a general-purpose computing device. The components of computer system/server 12 may include, but are not limited to, one or more processors or processing units 16, a system memory 28, and a bus 18 that couples various system components including system memory 28 to processor 16.
Bus 18 represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnects (PCI) bus.
Computer system/server 12 typically includes a variety of computer system readable media. Such media may be any available media that is accessible by computer system/server 12, and it includes both volatile and non-volatile media, removable and non-removable media.
System memory 28 can include computer system readable media in the form of volatile memory, such as random access memory (RAM) 30 and/or cache memory 32. Computer system/server 12 may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system 34 can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM, or other optical media can be provided. In such instances, each can be connected to bus 18 by one or more data media interfaces. As will be further depicted and described below, memory 28 may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments of the invention.
The embodiments of the invention may be implemented as a computer readable signal medium, which may include a propagated data signal with computer readable program code embodied therein (e.g., in baseband or as part of a carrier wave). Such a propagated signal may take any of a variety of forms including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A computer readable signal medium may be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device.
Program code embodied on a computer readable medium may be transmitted using any appropriate medium including, but not limited to, wireless, wireline, optical fiber cable, radio-frequency (RF), etc., or any suitable combination of the foregoing.
Program/utility 40, having a set (at least one) of program modules 42, may be stored in memory 28 by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. In general, program 40 performs the function of the present invention as described herein. For example, program 40 will: receive, in a computer memory medium, a set of information pertaining to the set of components associated with the virtual computing network, the set of components comprising a set of servers, a set of ports, a set of switches and a set of virtual machines (VMs), and the set of information describing a set of interrelationships between the set of components; generate, based on the set of information, a graphical representation depicting the set of interrelationships between the set of components; detect a failure (e.g., failure of a communication link between at least two of the set of components) in the virtual computing network; reconfigure, responsive to the failure, at least one of the set of interrelationships between the set of components based on a set of rules.
Along these lines, the set of information may be obtained from the set of switches, and the set of information may comprise at least one of the following: a set of routing tables, a virtual computing network configuration port mapping, or a Media Address Control (MAC) address to a set of Internet Protocol (IP) tables. Further, the set of information may be further obtained from the set of servers, and the set of information may further comprise at least one of the following: a set of mappings between the set of VMs and the set of switches, a set of mappings between the set of switches and the set of ports, or a set of mappings interbetween the set of ports. Moreover, the virtual computing network may comprise any type of virtual computing network such as a grid computing network, a cloud computing network, a virtual local area network (VLAN), a virtual private network, etc. Further the set of ports may comprise at least one virtual port and at least one physical port.
As will be further shown below, the graphical representation may comprise a hierarchical tree having a set of nodes corresponding to the set of components. The set of rules may comprise an ordered set of criteria for determining which interrelationships between the set of components to reconfigure so that the set of components remains accessible despite the failure.
Each of the operating system, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules 42 generally carry out the functions and/or methodologies of embodiments of the invention as described herein.
Computer system/server 12 may also communicate with one or more external devices 14 such as a keyboard, a pointing device, a display 24, etc.; one or more devices that enable a consumer to interact with computer system/server 12; and/or any devices (e.g., network card, modem, etc.) that enable computer system/server 12 to communicate with one or more other computing devices. Such communication can occur via I/O interfaces 22. Still yet, computer system/server 12 can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter 20. As depicted, network adapter 20 communicates with the other components of computer system/server 12 via bus 18. It should be understood that although not shown, other hardware and/or software components could be used in conjunction with computer system/server 12. Examples include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc.
Referring now to FIG. 2, a system diagram according to an embodiment of the present invention is shown. As depicted, FIG. 2 comprises management console 50 communicating with a set of servers 52A-N having a set of virtual machines (VMs) 54A-N, a set of virtual switches 56A-N, and a supervisor 58. Management console 50 further communicates with a network switch 60 that itself comprises a set of virtual local area networks (VLANS) 62A-N and a supervisor 60. In general, management console 50 may comprise program/utility 40 as shown in FIG. 1. That is, management console 50 may interact with supervisors 58 and 64 to implement the teachings recited herein.
In general, in a typical embodiment: the connections between the VMs 54A-N and the virtual switches 56A-N may be virtual; the connections between the servers 52A-N and the network switch 60 may be physical; the VLANs 62A-N created by the network switch 60 may be virtual; and the supervisors 58 and 64A-N represent the management/administrative functions within the respective equipment.
As will be further discussed below, management console 50 will configure the linking of disparate data sources (e.g., server VLAN data, switch VLAN data, VMs, virtual switches, etc.) into an interconnected information set, rendering the information into a hierarchical tree (e.g., human readable representation) that is used to identify alternate logical and physical paths between systems to mitigate communications path failures. Then a process to use the interconnection information set to reconfigure the infrastructure based on pre-defined business rules in the presence of a failure may be provided. In one example, the business rule is reconfigured based on lowest cost, and/or fastest links, and/or minimum reliability of connections.
Among other things, embodiments of the present invention obtain information from switch and server configuration tables, and then by application of algorithms set forth below, derives key relationships within the data. The embodiments set forth therein then render the information in a format that can be understood and acted upon. Upon a hardware failure, the invention determines a “fix” to the failure, based on predefined business rules and then reconfigures the infrastructure.
A. Generation of a Hierarchical Tree Representation
In a typical embodiment, management console 50 will obtain various pieces of information and construct a tree representation of the data. FIG. 3 depicts a method flow diagram of this process. The process is started in step R1. In step R2, the following information is obtained from network switch 60 (e.g., by management console 50):

    
    
        routing Tables (IP subnet to physical switch port relationship)
        VLAN Configuration (VLAN ID to Switch Physical Port relationship)
        MAC Configuration (switch port's MAC address to IP subnet associated to the port)

In step R3, management console 50 will also obtain from servers 52A-N, the following information:

        virtual server machine to virtual server switch relationship 16
        virtual server switch to server physical port relationship
        virtual server switch to virtual server port relationship
        virtual server port to physical server port mapping

In step R4, a hierarchical tree representation depicting the interrelationships between the network components is generated before the process is ended in step R5.

    
    


The following is some illustrative pseudo code for this process: Method step details for Block: Construct a tree representation of the data.
Loop: For each VLAN in switch configuration table,

    
    
        make a 1st layer (VLAN) node in the tree.
        
            Loop: For each physical switch port,
            
                make a 2nd layer (physical switch port) node and link node to the 1st layer (VLAN) node.
            
            
            Loop: For each physical port associated with the server,
            
                make a 3rd layer (Vswitch) node and link node to the 2nd layer (physical switch port) node.
            
            
            Loop: For each Vswitch associated with the server,
            
                make a 4th layer (virtual machine) node and link node to the 3rd layer (Vswitch) node.
            
            
        
        
    
    


The result of the above-described process is a tree graph linking the VMs to their associated VLANs overlaid with their physical attributes. An example of a tree graph so generated is illustrated in FIG. 4. It is noted in advance that FIG. 4 and the Figures that follow depict a possible tree-like representation and that other alternatives can be generated hereunder. In any event, as depicted, representation 70 comprises a tree-like diagram depicting the interrelationships/links between multiple components. As shown, at the root of tree 72 is VLAN1, which interacts with servers 74A-B by being linked/is coupled to physical ports 76A-D. Physical ports 76A-D can be coupled/linked to virtual switches 78A-D, which themselves can be coupled/linked to VMs 80A-D. In the event of a failure of any of the linkages shown in FIG. 4, representation 70 provides a snapshot view of possible reconfiguration alternatives.
B. Reconfiguration Alternatives
This section will discuss possible ways a networked computing environment (or the interrelationship between the components thereof) can be reconfigured in the event of a failure. Specifically, the flow chart of FIG. 5 illustrates the reconfiguration method steps. In this flow chart the following terms are used:

    
    
        Failed_Physical_Links—a physical layer network connection that is down or not functioning and thus preventing data flow.
        New_Physical_Port—a physical network interface that is connected to the VLAN and available for use by a Vswitch.
        Previous Vswitch—a Vswitch that has VMs that are attached.
        Replacement Vswitch—A newly created or already created Vswitch that can be utilized by VMs.

It is understood in advance that a “connection failure” is not limited to a physical failure (e.g., a physical wire). Connection failures may be the result of a logical failure (e.g., a mis-configuration, a software error, a database error, etc.). The embodiments of the present invention are intended to be applicable to all types of failures, not just physical.

    
    


The process starts in step S1, and in step S2, it is determined whether there is a Failed_Physical_Links. If not, the process returns. If so, the process proceeds to step S3 where it is determined whether there is another physical port attached to the VLAN. If not, the process ends in step S4. If so, a New_Physical_Port is chosen in step S5 based on a set of business rules. In performing step S5, the determination of which link within the interconnection information to be set is based on the infrastructure administrator defining an ordered set of criteria with the selection based on a best choice. For example, if link costs were to be minimized, each link would have an associated cost, and the method would systematically search for the lowest cost link among the possible interconnection. Searching for the lowest cost link among a set of links is known and declared enabling art. For example, if remaining link capacity were used, such that each VM would be allocated to the next most available link, each link would have an associated spare capacity measure, and the method would systematically search for the largest spare compactly. It would then, in turn, assign the VMs to the links.
Regardless, in step S6, the tree representation is searched, and the virtual switches that are using the physical port on the Failed_Physical_Link are moved to the New_Physical_Port. In step S7, the tree representation is searched and any VMs that are associated with the previous virtual switch are moved to a replacement virtual switch. In step S8, the tree representation is then rebuilt based on the new configuration before the process is ended in step S9.
Referring now to FIGS. 6-11, the concepts presented hereinabove will be shown and described in greater detail. FIG. 6 shows tree representation 70 where VMs 80C-D are no longer accessible. As depicted, in FIG. 7, this can occur due to a failure of physical link 84C, which would prevent accessibility to VMs 80C-D. As shown in FIG. 8, VMs 80C-D can be kept in service by reconfiguring virtual switch 78C to connect to physical port 76D. FIG. 9 shows another approach whereby VMs 80C-D are reconfigured to couple to virtual switch 78B in server 74A. FIG. 10 shows yet another approach whereby VMs 80C-D are reconfigured to couple to virtual switch 78D while virtual switch 78C (not shown) was removed from service. FIG. 11 shows a hybrid approach whereby VM 80C is reconfigured to couple to virtual switch 78B of server 74A, while VM 80D is reconfigured to couple to virtual switch 78D of server 74B. In any of the cases shown in FIGS. 8-11, both VMs 80C-D affected by the failure were able to be kept in service due to a graphical understanding of the overall system and the interrelationships between the components made possible hereunder.
It is understood that reconfiguration decisions in moving to a new server can be based on available link capacity, server capacity, memory capacity, CPU utilization, power usage, cost, proximity to related VMs, and physical separation requirement for different VMs. It is understood that additional considerations may be used to determine the reconfiguration decision.
C. Additional Embodiments
With the information obtained in building the tree representation, augmented by ancillary information obtained by existing query methods, the following representations of the information can be rendered. Using these representations, additional functions and services can be achieved.
Referring now to FIG. 12, a representation 100 of servers 102 and virtual machines 104 are instantiated on the servers along with their attributes (e.g., memory usage, core usage, uptime, total CPU time, I/O counts, operating system (OS) type, power type, etc.). Representation 100 enables the capturing key of server data points to allow decisions to be made on moving virtual machines to another server based on the attribute gathered.
Referring now to FIG. 13, a representation 110 of storage systems 112 and their associated virtual systems 114 along with their attributes (e.g., storage association, remaining disk space, block size, storage location, storage speed, storage reliability/failure recovery, etc.) is shown. Representation 100 enables the capturing of key data storage points associated with each virtual machine it enables to allow decisions to be made on tuning storage parameters and allocations to improve the overall operating environment.
Referring now to FIG. 14, a representation 120 of virtual networks 122 and their associated virtual machines 124 along with their attributes (e.g., IP address, gateway error, bit error rate uptime, link rate, usage information, etc.) is shown. Representation 120 enables the capturing key virtual network data points to allow operational decisions to be made on balancing network load and routing around highly utilized environments, and enables reconfiguration decisions to be proactively made.
Referring now to FIG. 15, a representation 130 of virtual machines 134 and their consumption of real resource within the physical server (“i”) 132, along with their attributes (e.g., health indicator of the physical resource for memory, disk space, CPU availability, network bandwidth, etc.) is shown. Representation 130 enables the capturing of key virtual machine data points as these data points relate to real physical server to allow operational decisions to be made on balancing load and routing around highly utilized environments, and enables reconfiguration decisions to be proactively made.
Referring now to FIG. 16, a method flow diagram according to an embodiment of the present invention is shown (e.g., as enabled by engine 50 of FIG. 2). As depicted, in step T1, a set of information pertaining to a set of components associated with a virtual computing network is received. As indicated above, the set of components may comprise a set of servers, a set of ports, a set of switches and a set of virtual machines (VMs), and the set of information describing a set of interrelationships between the set of components. In step T2, a graphical representation depicting the set of interrelationships between the set of components is generated based on the set of information. In step T3, a failure in the virtual computing network is detected. In step T4, responsive to the failure, at least one of the set of interrelationships between the set of components is reconfigured based on a set of rules.
