DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

System Overview:

Referring to FIG. 1, there is shown storage management process 10 that may reside on and may be executed by storage system 12, which may be connected to network 14 (e.g., the Internet or a local area network). 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.

The instruction sets and subroutines of storage management process 10, which may be stored on storage device 16 included within storage system 12, may be executed by one or more processors (not shown) and one or more memory architectures (not shown) included within storage system 12. Storage device 16 may include but is 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 14 may be connected to one or more secondary networks (e.g., network 18), examples of which may include but are not limited to: a local area network; a wide area network; or an intranet, for example.

Various IO requests (e.g. IO request 20) may be sent from client applications 22, 24, 26, 28 to storage system 12. Examples of IO request 20 may include but are not limited to data write requests (i.e. a request that content be written to storage system 12) and data read requests (i.e. a request that content be read from storage system 12).

The instruction sets and subroutines of client applications 22, 24, 26, 28, which may be stored on storage devices 30, 32, 34, 36 (respectively) coupled to client electronic devices 38, 40, 42, 44 (respectively), may be executed by one or more processors (not shown) and one or more memory architectures (not shown) incorporated into client electronic devices 38, 40, 42, 44 (respectively). Storage devices 30, 32, 34, 36 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 38, 40, 42, 44 may include, but are not limited to, personal computer 38, laptop computer 40, smartphone 42, notebook computer 44, a server (not shown), a data-enabled, cellular telephone (not shown), and a dedicated network device (not shown).

Users 46, 48, 50, 52 may access storage system 12 directly through network 14 or through secondary network 18. Further, storage system 12 may be connected to network 14 through secondary network 18, as illustrated with link line 54.

The various client electronic devices may be directly or indirectly coupled to network 14 (or network 18). For example, personal computer 38 is shown directly coupled to network 14 via a hardwired network connection. Further, notebook computer 44 is shown directly coupled to network 18 via a hardwired network connection. Laptop computer 40 is shown wirelessly coupled to network 14 via wireless communication channel 56 established between laptop computer 40 and wireless access point (i.e., WAP) 58, which is shown directly coupled to network 14. WAP 58 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 56 between laptop computer 40 and WAP 58. Smartphone 42 is shown wirelessly coupled to network 14 via wireless communication channel 60 established between smartphone 42 and cellular network/bridge 62, which is shown directly coupled to network 14.

Client electronic devices 38, 40, 42, 44 may each execute an operating system, examples of which may include but are not limited to Microsoft Windows™, Apple Macintosh™, Redhat Linux™, or a custom operating system.

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.

Referring also to FIG. 2, storage system 12 may include storage processor 100 and a plurality of storage targets T1-n (e.g. storage targets 102, 104, 106, 108). Storage targets 102, 104, 106, 108 may be configured to provide various levels of performance and/or high availability. For example, one or more of storage targets 102, 104, 106, 108 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, one or more of storage targets 102, 104, 106, 108 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 storage targets 102, 104, 106, 108 are 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, storage targets 102, 104, 106, 108 may be configured as a RAID 3, RAID 4, RAID 5 or RAID 6 array.

While in this particular example, storage system 12 is shown to include four storage targets (e.g. storage targets 102, 104, 106, 108), this is for illustrative purposes only and is not intended to be a limitation of this disclosure. Specifically, the actual number of storage targets may be increased or decreased depending upon e.g. the level of redundancy/performance/capacity required.

Storage system 12 may also include one or more coded targets 110. 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 storage targets 102, 104, 106, 108. 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.

While in this particular example, storage system 12 is shown to include one coded target (e.g., coded target 110), this is for illustrative purposes only and is not intended to be a limitation of this disclosure. Specifically, the actual number of coded targets may be increased or decreased depending upon e.g. the level of redundancy/performance/capacity required.

Examples of storage targets 102, 104, 106, 108 and coded target 110 may include one or more electro-mechanical hard disk drives and/or solid-state/flash devices, wherein a combination of storage targets 102, 104, 106, 108 and coded target 110 and processing/control systems (not shown) may form data array 112.

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 storage processor 100 is a RAID controller card and storage targets 102, 104, 106, 108 and/or coded target 110 are individual “hot-swappable” hard disk drives. Another 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 storage processor 100 may be e.g., a server computer and each of storage targets 102, 104, 106, 108 and/or coded target 110 may be a RAID device and/or computer-based hard disk drives. Further still, one or more of storage targets 102, 104, 106, 108 and/or coded target 110 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. storage processor 100, storage targets 102, 104, 106, 108, and coded target 110) may be coupled using network infrastructure 114, 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 circuit switched/packet switched network.

Storage system 12 may execute all or a portion of storage management process 10. The instruction sets and subroutines of storage management process 10, which may be stored on a storage device (e.g., storage device 16) coupled to storage processor 100, may be executed by one or more processors (not shown) and one or more memory architectures (not shown) included within storage processor 100. Storage device 16 may include but is 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.

As discussed above, various IO requests (e.g. IO request 20) may be generated. For example, these IO requests may be sent from client applications 22, 24, 26, 28 to storage system 12. Additionally/alternatively and when storage processor 100 is configured as an application server, these IO requests may be internally generated within storage processor 100. Examples of IO request 20 may include but are not limited to data write request 116 (i.e. a request that content 118 be written to storage system 12) and data read request 120 (i.e. a request that content 118 be read from storage system 12).

During operation of storage processor 100, content 118 to be written to storage system 12 may be processed by storage processor 100. Additionally/alternatively and when storage processor 100 is configured as an application server, content 118 to be written to storage system 12 may be internally generated by storage processor 100.

As discussed above, the instruction sets and subroutines of storage management process 10, which may be stored on storage device 16 included within storage system 12, may be executed by one or more processors (not shown) and one or more memory architectures (not shown) included within storage system 12. Accordingly, in addition to being executed on storage processor 100, some or all of the instruction sets and subroutines of storage management process 10 may be executed by one or more processors (not shown) and one or more memory architectures (not shown) included within data array 112.

Storage processor 100 may include frontend cache memory system 122. Examples of frontend cache memory system 122 may include but are not limited to a volatile, solid-state, cache memory system (e.g., a dynamic RAM cache memory system) and/or a non-volatile, solid-state, cache memory system (e.g., a flash-based, cache memory system).

During operation of storage processor 100, content 118 to be written to storage system 12 may be received by storage processor 100. Additionally/alternatively and when storage processor 100 is configured as an application server, content 118 to be written to storage system 12 may be internally generated by storage processor 100.

Storage processor 100 may initially store content 118 within frontend cache memory system 122. Depending upon the manner in which frontend cache memory system 122 is configured, storage processor 100 may immediately write content 118 to data array 112 (if frontend cache memory system 122 is configured as a write-through cache) or may subsequently write content 118 to data array 112 (if frontend cache memory system 122 is configured as a write-back cache).

Data array 112 may include backend cache memory system 124. Examples of backend cache memory system 124 may include but are not limited to a volatile, solid-state, cache memory system (e.g., a dynamic RAM cache memory system) and/or a non-volatile, solid-state, cache memory system (e.g., a flash-based, cache memory system). During operation of data array 112, content 118 to be written to data array 112 may be received from storage processor 100. Data array 112 may initially store content 118 within backend cache memory system 124 prior to being stored on e.g. one or more of storage targets 102, 104, 106, 108, and coded target 110.

Additionally, assume that data array 112 defines and exposes Logical Units (e.g., LUN 126, 128, 130, 132) that may allow for the storage of data within data array 112.

The Storage Management Process:

As will be discussed below in greater detail, storage management process 10 may be configured to implement procedures/rules that reduce the risk of accidental deletion of objects within storage system 12. Examples of such objects may include but are not limited to data files, domain specific objects, data folders, data directories, LUNs, etc.

Assume for illustrative purposes that user 46 is working on a project that requires user 46 to manipulate data (e.g., add data, delete data and/or modify data) within storage system 12. Accordingly user 46 may access storage system 12 via client application 22 and personal computer 38. Further assume that user 52 is a supervisor of user 46 and, therefore, user 52 may access storage system 12 via client application 28 and notebook computer 44.

Referring also to FIG. 3, assume that storage management process 10 defines 150 at least a portion of storage system 12 as a data storage space. As discussed above, assume that storage management process 10 defines 150 LUNs 126, 128, 130, 132 for (in this example) user 46 so that user 46 may work on their project. LUNs 126, 128, 130, 132 may or may not be accessible buy other users (e.g., users 48, 50) of storage system 10. However, LUNs 126, 128, 130, 132 may be accessible user 52, as user 52 is the supervisor of user 46.

Storage management process 10 may assign 152 a rate limit to this data storage space (e.g., LUNs 126, 128, 130, 132), thus defining default rate limit 134. As will be discussed below in greater detail, default rate limit 134 may be assigned 152 by storage management process 10 in order to reduce the risk of accidental deletion of objects, such as data files (examples of which may include but are not limited to e.g., documents, spreadsheets, emails, and database records), domain specific objects (an example of which may include but is not limited to e.g., a movie), data folders, data directories, LUNs, etc. within storage system 12. Default rate limit 134 may define one or more of: a maximum number of objects per unit time; and a maximum quantity of data per unit time. Specifically, default rate limit 134 may define the maximum number of objects (e.g., data files, data folders, data directories and/or LUNs) that e.g., user 46 may delete per unit time (e.g., per minute, per hour, per day and/or per week). Additionally/alternatively, default rate limit 134 may define the maximum quantity of data (e.g., in megabytes, in gigabytes and/or terabytes) that e.g., user 46 may delete per unit time (e.g., per minute, per hour, per day and/or per week). Further, default rate 134 may be static or dynamic (e.g., formulaic). For example, default rate limit 134 may be defined as a formula (e.g., the maximum number of files that can be deleted is no more than 110% of the average number of files deleted the previous week).

Assume for illustrative purposes that (for this example) default rate limit 134 assigned 152 by storage management process 10 is a 1,000 files per hour maximum deletion rate for user 46 with respect to e.g., LUNs 126, 128, 130, 132. While default rate limit 134 is defined in this example as being for user 46 and concerning e.g., LUNs 126, 128, 130, 132, 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.

For example, default rate limit 134 may be broad-based and may apply to all users of storage system 12, wherein every user of storage system 12 may have the same default rate limit. Alternatively, default rate limit 134 may be configured so that it is assigned to a group of users of storage system 12, wherein e.g., senior administrators of storage system 12 may have a high default rate limit, junior administrators of storage system 12 may have a medium default rate limit, and users of storage system 12 may have a low default rate limit. Further, default rate limit 134 may be broad-based and may apply to all storage spaces within storage system 12, as opposed to only (in this example) LUNs 126, 128, 130, 132. Additionally, while the following discussion concerns the process of setting a default rate limit for storage system 12, it is understood and considered to be within the scope of this disclosure the process of setting multiple discrete rate limits for storage system 12, wherein storage management process 10 may assign 152 a first rate limit for one type of operation (e.g., object creation), may assign 152 a second rate for another type of operation (e.g., object deletion) and may assign a third rate limit for third type of operation (e.g., object modifications)

While in this particular example, default rate limit 134 is assigned 152 by storage management process 10 to be a 1,000 data files per hour maximum deletion rate, default rate limit 134 may be multi-faceted and may additionally define e.g., a maximum quantity of data that (in this example) user 46 may delete per unit time (e.g., per minute, per hour, per day and/or per week). For example, default rate limit 134 may be assigned 152 by storage management process 10 to be a 1,000 data files per hour and/or one terabyte per day maximum deletion rate.

Continuing with the above-stated example in which default rate limit 134 is assigned 152 by storage management process 10 to be a 1,000 data files per hour maximum deletion rate for user 46 with respect to e.g., LUNs 126, 128, 130, 132, storage management process 10 may compare 154 operations performed on objects (e.g., data files, data folders, data directories and/or LUNs) within the data storage space (e.g., LUNs 126, 128, 130, 132) to default rate limit 134 (e.g., a 1,000 files per hour maximum deletion rate) to determine if default rate limit 134 is exceeded.

The operations performed on objects (e.g., data files, data folders, data directories, LUNs, etc.) within the data storage space (e.g., e.g., LUNs 126, 128, 130, 132) may include but is not limited to one or more of: data object deletion operations (e.g., operations that result in the deletion of data); data object migration operations (e.g., operations that result in the movement of data); data object modification operations (e.g., operations that result in the modification of data); data object creation operations (e.g., operations that result in the creation of data); data object copying operations (e.g., operations that result in the copying of data); and data object archiving operations (e.g., operations that result in the archiving of data). Additionally and with respect to domain specific objects, such operations may include the deleting of a scene or a single frame; and the modification of the sequence of frames/scene fragments. As is known in the art, such operations may be fully or partially automated using a script and/or a batch process.

Accordingly, if user 46 selects (for deletion) under 1,000 data files (or one or more data folders/data directories/LUNs that include under 1,000 data files), storage management process 10 may compare 154 the operation (e.g., the deletion of under 1,000 data files) to default rate limit 134 (e.g., a 1,000 data files per hour maximum deletion rate) to determine if default rate limit 134 is exceeded. In this particular example and since default rate limit 134 is not being exceeded, storage management process 10 may allow this operation (e.g., the deletion of under 1,000 data files or one or more data folders/data directories/LUNs that include under 1,000 data files) to proceed.

Conversely, if user 46 selects (for deletion) over 1,000 data files (or one or more data folders/data directories/LUNs that include over 1,000 data files), storage management process 10 may compare 154 the operation (e.g., the deletion of over 1,000 data files) to default rate limit 134 (e.g., a 1,000 data files per hour maximum deletion rate) and determine that default rate limit 134 has been exceeded.

When comparing 154 operations performed on objects (e.g., data files, data folders, data directories, LUNs, etc.) within the data storage space (e.g., e.g., LUNs 126, 128, 130, 132) to default rate limit 134 to determine if default rate limit 134 has been exceeded, storage management process 10 may compare 156 a plurality of discrete operations performed on objects within the data storage space (e.g., e.g., LUNs 126, 128, 130, 132) to default rate limit 134 to determine if default rate limit 134 has been exceeded.

Accordingly, if user 46 first selects (for deletion) 999 data files (or one or more data folders/data directories/LUNs that include 999 data files), storage management process 10 may compare 154 the operation (e.g., the deletion of 999 data files) to default rate limit 134 (e.g., a 1,000 data files per hour maximum deletion rate) and determine that default rate limit 134 has not been exceeded, and storage management process 10 may allow this operation (e.g., the deletion of 999 data files) to proceed.

However, assume that user 46 subsequently selects (for deletion) another 999 data files (or one or more data folders/data directories/LUNs that include 999 data files). Storage management process 10 may compare 156 the plurality of discrete operations (e.g., the sum of the first 999 data file deletions and the second 999 data file deletions) performed on objects within the data storage space (e.g., e.g., LUNs 126, 128, 130, 132) to determine if default rate limit 134 has been exceeded.

Accordingly, if user 46 selected the second batch of 999 data files (or one or more data folders/data directories/LUNs that include 999 data files) e.g., 90 minutes after the deletion of the first batch of 999 data files, storage management process 10 may compare 156 the plurality of discrete operations (e.g., the deletion of the second batch of 999 data files 90 minutes after the first batch of 999 data files) to default rate limit 134 (e.g., a 1,000 data files per hour maximum deletion rate) and determine that default rate limit 134 has not been exceeded, and storage management process 10 may allow this operation (e.g., the deletion of the second batch of 999 data files) to proceed.

Conversely, if user 46 selected the second batch of 999 data files (or one or more data folders/data directories/LUNs that include 999 data files) e.g., 30 minutes after the deletion of the first batch of 999 data files, storage management process 10 may compare 156 the plurality of discrete operations (e.g., the deletion of the second batch of 999 data files 30 minutes after the first batch of 999 data files; for a total of 1,998 data files being deleted within 30 minutes) to default rate limit 134 (e.g., a 1,000 data files per hour maximum deletion rate) and determine that default rate limit 134 has been exceeded.

Concerning the above-described comparisons (e.g., comparisons 154, 156) performed by storage management process 10, these comparisons may be performed prior to the operation being initiated (as described above). Additionally/alternatively, these comparisons may be performed as the operations are occurring, wherein selecting e.g., 1,200 files for deletion will not immediately make the operation fail (as will be described below).

If storage management process 10 determines (when comparing 154 a single operation and/or comparing 156 the cumulative impact of a plurality of discrete operations) that default rate limit 134 has been exceeded, storage management process 10 may implement 158 one or more remedial actions concerning the operations performed on objects within the data storage space (e.g., e.g., LUNs 126, 128, 130, 132).

Examples of these remedial action may include but are not limited to one or more of: stopping an operation that exceeds default rate limit 134; requesting user confirmation concerning the operation that exceeds default rate limit 134; requesting supervisor authorization concerning the operation that exceeds default rate limit 134; and slowing the operation that exceeds default rate limit 134.

Concerning stopping the operation that exceeds default rate limit 134, if user 46 selects (for deletion) 1,200 data files, storage management process 10 may a) stop the operation prior to any deletions occurring (resulting in no data files being deleted); or b) delete the first 1,000 data files and then stop the operation (resulting in 1,000 of the 1,200 data files being deleted). Storage management process 10 may render message 200 (on personal computer 38) to inform user 46 of the stoppage (as shown in FIG. 4A).

Concerning slowing the operation that exceeds default rate limit 134, if user 46 selects (for deletion) 1,200 data files, storage management process 10 may delete the first 1,000 data files at a normal deletion rate and may then slow down the deletion rate by a defined percentage (e.g., 50%) or to a slower fixed deletion rate so that the remaining 200 data files are deleted but at a slower deletion rate. Storage management process 10 may render message 202 (on personal computer 38) to inform user 46 of the slowdown (as shown in FIG. 4B).

Concerning requesting user confirmation and/or supervisor authorization with respect to the operation that exceeds default rate limit 134, if user 46 selects (for deletion) 1,200 data files, storage management process 10 may enable 160 a user (e.g., user 46 and/or (supervising) user 52) of the data storage space (e.g., e.g., LUNs 126, 128, 130, 132). to override default rate limit 134, thus defining an overridden rate limit (e.g., overridden rate limit 134′). Examples of overridden rate limit 134′ may include but are not limited to: a) no limit and b) a multiple of the original limit (e.g., 2× default rate limit 134). Storage management process 10 may render message 204 (on personal computer 38 and/or notebook computer 44) to inform user 46 and/or user 52 that authorization is required (as shown in FIG. 4C).

In the event that default rate limit 134 is overridden, storage management process 10 may implement a delay (e.g., a few minutes) to enable the user to ensure that the deletion operation was intended. Storage management process 10 may be configured to reestablish 162 default rate limit 134 after a defined period of time. Examples of this defined period of time may include but are not limited to: a) immediately and b) one hour/one day/one week later.
