Augmented reality process 10 may be implemented as a server-side process, a client-side process, or a hybrid server-side/client-side process. For example, augmented reality process 10 may be implemented as a purely server-side process via server-side augmented reality process 10s.

Server-side augmented reality process 10s may be a server application and may reside on and may be executed by computing device 14, which may be connected to network 16 (e.g., the Internet or a local area network). Examples of computing device 14 may include, but are not limited to: a personal computer, a laptop computer, a personal digital assistant, a data-enabled cellular telephone, a notebook computer, a television with one or more processors embedded therein or coupled thereto, a cable/satellite receiver with one or more processors embedded therein or coupled thereto, a server computer, a series of server computers, a mini computer, a mainframe computer, or a dedicated network device.
The instruction sets and subroutines of server-side augmented reality process 10s, which may be stored on storage device 18 coupled to computing device 14, may be executed by one or more processors (not shown) and one or more memory architectures (not shown) included within computing device 14. Examples of storage device 18 may include but are not limited to: a hard disk drive; a tape drive; an optical drive; a RAID device; a random access memory (RAM); a read-only memory (ROM); and all forms of flash memory storage devices.
Network 16 may be connected to one or more secondary networks (e.g., network 20), examples of which may include but are not limited to: a local area network; a wide area network; or an intranet, for example.
Examples of client-side augmented reality processes 10c1, 10c2, 10c3, 10c4 may include but are not limited to a web browser, a specialized desktop application, a game console user interface, or a specialized handheld application (e.g., an application running on e.g., the Android™ platform or the iPhone™ platform). The instruction sets and subroutines of client-side augmented reality processes 10c1, 10c2, 10c3, 10c4, which may be stored on storage devices 22, 24, 26, 28 (respectively) coupled to client electronic devices 30, 32, 34, 36 (respectively), may be executed by one or more processors (not shown) and one or more memory architectures (not shown) incorporated into client electronic devices 30, 32, 34, 36 (respectively). Examples of storage devices 22, 24, 26, 28 may include but are not limited to: hard disk drives; tape drives; optical drives; RAID devices; random access memories (RAM); read-only memories (ROM), and all forms of flash memory storage devices.
Examples of client electronic devices 30, 32, 34, 36 may include, but are not limited to, data-enabled, cellular telephone 30, laptop computer 32, personal digital assistant 34, personal computer 36, a notebook computer (not shown), a server computer (not shown), a gaming console (not shown), a smart television (not shown), and a dedicated network device (not shown). Client electronic devices 30, 32, 34, 36 may each execute an operating system, examples of which may include but are not limited to Microsoft Windows™, Android™, WebOS™, iOS™, Redhat Linux™, or a custom operating system.
Users 38, 40, 42, 44 may access augmented reality process 10 directly through network 16 or through secondary network 20. Further, augmented reality process 10 may be connected to network 16 through secondary network 20, as illustrated with link line 46.
The various client electronic devices (e.g., client electronic devices 30, 32, 34, 36) may be directly or indirectly coupled to network 16 (or network 20). For example, data-enabled, cellular telephone 30 and laptop computer 32 are shown wirelessly coupled to network 16 via wireless communication channels 48, 50 (respectively) established between data-enabled, cellular telephone 30, laptop computer 32 (respectively) and cellular network/bridge 52, which is shown directly coupled to network 16. Further, personal digital assistant 34 is shown wirelessly coupled to network 16 via wireless communication channel 54 established between personal digital assistant 34 and wireless access point (i.e., WAP) 56, which is shown directly coupled to network 16. Additionally, personal computer 36 is shown directly coupled to network 20 via a hardwired network connection.
WAP 56 may be, for example, an IEEE 802.11a, 802.11b, 802.11g, 802.11n, Wi-Fi, and/or Bluetooth device that is capable of establishing wireless communication channel 54 between personal digital assistant 34 and WAP 56. As is known in the art, IEEE 802.11x specifications may use Ethernet protocol and carrier sense multiple access with collision avoidance (i.e., CSMA/CA) for path sharing. The various 802.11x specifications may use phase-shift keying (i.e., PSK) modulation or complementary code keying (i.e., CCK) modulation, for example. As is known in the art, Bluetooth is a telecommunications industry specification that allows e.g., mobile phones, computers, and personal digital assistants to be interconnected using a short-range wireless connection.
As discussed above, augmented reality process 10 may be utilized to visually monitor the status of various components/devices included within a storage system (e.g., storage system 12). Storage system 12 may be utilized by organizations to process and store data. Examples of storage system 12 may include, but are not limited to: a Network Attached Storage (NAS) system, a Storage Area Network (SAN), a personal computer with a memory system, a server computer with a memory system, and a cloud-based device with a memory system.
As is known in the art, a SAN may include one or more of a personal computer, a server computer, a series of server computers, a mini computer, a mainframe computer, a RAID device and a NAS system. The various components of storage system 12 may execute one or more operating systems, examples of which may include but are not limited to: Microsoft Windows Server™; Redhat Linux™ Unix, or a custom operating system, for example.
For illustrative purposes, storage system 12 will be described as being a network-based storage system that includes a plurality of electro-mechanical backend storage devices. However, this is for illustrative purposes only and is not intended to be a limitation of this disclosure, as other configurations are possible and are considered to be within the scope of this disclosure.

Plurality of storage targets 102 may be configured to provide various levels of performance and/or high availability. For example, a portion of plurality of storage targets 102 may be configured as a RAID 0 array, in which data is striped across storage targets. By striping data across a plurality of storage targets, improved performance may be realized. However, RAID 0 arrays do not provide a level of high availability. Accordingly, a portion of plurality of storage targets 102 may be configured as a RAID 1 array, in which data is mirrored between storage targets. By mirroring data between storage targets, a level of high availability is achieved as multiple copies of the data are stored within storage system 12.
While plurality of storage targets 102 is discussed above as being configured in a RAID 0 or RAID 1 array, this is for illustrative purposes only and is not intended to be a limitation of this disclosure, as other configurations are possible. For example, plurality of storage targets 102 may be configured as a RAID 3, RAID 4, RAID 5 or RAID 6 array.
Plurality of storage targets 102 may include one or more coded targets. As is known in the art, a coded target may be used to store coded data that may allow for the regeneration of data lost/corrupted on one or more of plurality of storage targets 102. An example of such a coded target may include but is not limited to a hard disk drive that is used to store parity data within a RAID array. The quantity of coded targets included within plurality of storage targets 102 may be increased or decreased depending upon e.g. the level of redundancy/performance/capacity required.
Examples of plurality of storage targets 102 may include one or more electro-mechanical hard disk drives and/or solid-state/flash devices, wherein the combination of plurality of storage targets 102 and processing/control systems (e.g., processing/control system 104) may form storage array 106.
The manner in which storage system 12 is implemented may vary depending upon e.g. the level of redundancy/performance/capacity required. For example, storage system 12 may be a RAID device in which front-end computing system 100 is a RAID controller card and plurality of storage targets 102 are individual “hot-swappable” hard disk drives. An example of such a RAID device may include but is not limited to an NAS device. Alternatively, storage system 12 may be configured as a SAN, in which front-end computing system 100 may be e.g., a server computer and each of plurality of storage targets 102 may be a RAID device and/or computer-based hard disk drive. Further still, one or more of plurality of storage targets 102 may be a SAN.
In the event that storage system 12 is configured as a SAN, the various components of storage system 12 (e.g. front-end computing system 100, plurality of storage targets 102, and processing/control system 106) may be coupled using network infrastructure 108, examples of which may include but are not limited to an Ethernet (e.g., Layer 2 or Layer 3) network, a fiber channel network, an InfiniBand network, or any other network infrastructure.

An IT rack (e.g., IT rack 152) may be utilized to store and organize the IT components of storage system 12. For example, IT rack 152 may be placed within a computer room and various IT components may be attached to rails (e.g., NEMA rails 154, 156) included within IT rack 152, wherein these rails (e.g., NEMA rails 154, 156) may have a standard and defined spacing between them (e.g., 19″). Typically, IT devices that are configured to fit within IT rack 152 may be described as rack-mountable IT devices. Alternatively. IT device 150 may be a free-standing device that does not require an IT rack for mounting.

Augmented Reality Process:
Assume for the following example that user 38 is an IT service technician that maintains storage system 12 and user 38 (via data-enabled, cellular telephone 30) wishes to use augmented reality process 10 to determine the “health” of storage system 12. Further assume for this illustrative example that storage system 12 includes an identification device (e.g., identification device 242) that may be used by augmented reality process 10 to positively identify storage system 12. Examples of identification device 242 may include but are not limited to an optical symbol (e.g., such as a QR code or a barcode) affixed to at least one IT component (included in storage system 12) and a wireless identifier tag (e.g., an RFID tag) affixed to at least one IT component (included in storage system 12). In this example, identifier 242 is shown affixed to battery backup system 236 included in storage system 12.
Referring also to
If identification device 242 is a wireless identifier tag (e.g., such as an RFID tag), augmented reality process 10 may scan 252 identification device 242 (i.e., the wireless identifier tag affixed to battery backup system 236) to generate unique identifier 58 (
Augmented reality process 10 may receive 254 unique identifier 58 on the client electronic device (e.g., data-enabled, cellular telephone 30) and may associate 256 unique identifier 58 with at least one IT component. For example, upon user 38 scanning 250, 252 identification device 242 and receiving 254 unique identifier 48 on data-enabled, cellular telephone 30, augmented reality process 10 may compare unique identifier 58 to a database (e.g., database 60) of known unique identifiers, wherein each of these known unique identifiers may define a unique storage system. Continuing with the above-stated example, assume that unique identifier 58 is matched to one of the unique identifiers included within data 60, thus associating 256 unique identifier 58 with one or more IT components included within storage system 12.
Accordingly and in this example, unique identifier 58 is associated 256 with a storage system (e.g., storage system 12) that includes disk array system 200 (having storage targets 202, 204, 206, 208, 210, 212, 214, 216, 218, 220, 222, 224), server system 226 (having processors 228, 230, 232, 234), and battery backup system 236 (having battery packs 238, 240).
Augmented reality process 10 may obtain 258 status information 70 concerning the one or more IT components included within storage system 12. Since storage system 12 includes disk array system 200, server system 226, and battery backup system 236, the status information (e.g., status information 70) obtained 258 by augmented reality process 10 may include status information concerning these three IT components (namely disk array system 200, server system 226, and battery backup system 236).
Specifically, augmented reality process 10 may obtain 258 status information 70 for disk array system 200, server system 226, and battery backup system 236, wherein the status information (e.g., status information 70) obtained 258 by augmented reality process 10 may include status information concerning storage targets 202, 204, 206, 208, 210, 212, 214, 216, 218, 220, 222, 224 (included within disk array system 200), processors 228, 230, 232, 234 (included within server system 226), and battery packs 238, 240 (included within battery backup system 236).
For this example, assume that status information 70 obtained 258 by augmented reality process 10 identifies storage targets 202, 204, 208, 212, 216, 220, 222, 224 as operating properly, storage targets 206, 214 as failing (e.g., due to concerning SMART data) and storage targets 210, 218 as having failed. The status information concerning these storage targets may be obtained by augmented reality process 10 polling disk array system 200.
Further, assume that status information 70 obtained 258 by augmented reality process 10 identifies processors 230, 234 as managing a normal workload and processors 228, 232 as being overloaded. The status information concerning these processors may be obtained by augmented reality process 10 polling server system 226.
Additionally, assume that status information 70 obtained 258 by augmented reality process 10 identifies battery pack 238 as operating normally and battery pack 240 as failing (e.g., incapable of holding a full charge). The status information concerning these battery packs may be obtained by augmented reality process 10 polling battery backup system 236.

When generating 260 visual representation 300 of the IT components (e.g., disk array system 200, server system 226, and battery backup system 236), augmented reality process 10 may capture 262 an image of the IT components (e.g., disk array system 200, server system 226, and battery backup system 236) using a camera (e.g., camera 304) included within the client electronic device (e.g., data-enabled, cellular telephone 30), thus generating a captured image. Augmented reality process 10 may then render 264 this captured image on display screen 302 of the client electronic device (e.g., data-enabled, cellular telephone 30), thus generating 260 visual representation 300 (e.g., a real time view) of the IT components (e.g., disk array system 200, server system 226, and battery backup system 236) of storage system 12.

Since and as discussed above, storage targets 202, 204, 208, 212, 216, 220, 222, 224 are operating properly, these storage targets may be shaded green within graphical representation 350. And since storage targets 206, 214 are failing, these storage targets may be shaded yellow within graphical representation 350. And since storage targets 210, 218 have failed, these storage targets may be shaded red within graphical representation 350.
Further and as discussed above, since processors 230, 234 are managing a normal workload, these processors may be shaded green within graphical representation 350. And since processors 228, 232 as being overloaded, these processors may be shaded yellow within graphical representation 350.
Additionally and as discussed above, since battery pack 238 is operating normally, this battery pack may be shaded green within graphical representation 350. And since battery pack 240 is failing, this battery pack may be shaded yellow within graphical representation 350.
Other specific monitored and defined within graphical representation 350 may include but are not limited to: temperature, length of time in service, fan speed, error codes, network congestion, dropped packets, array component utilization, and SLO (Service Level Objective) compliance status.
As is known in the art, SLO compliance is indicative of how well the workload of a storage group/system is complying with the overall Service Level Objective (SLO). Possible values may include but are not limited to:
