The present invention, in some embodiments thereof, relates to storage management and presentation and, more particularly, but not exclusively, to methods and/or systems for managing and/or presenting characteristics of storage pools.
Electronic storage and electronic storage virtualization has undergone a dramatic change over the past few years. Emerging storage technologies such as solid state drives and cloud storage have transformed the storage field. Emerging storage-relevant technologies are related to: storage controllers, data reliability and prevention of data loss, storage efficiency, data capacity reduction techniques, file systems management, parallel access protocols such as parallel network file systems (pNFS), connectivity methods (for example Fiber Channel over Ethernet, (FCoE)) and synchronization/a-synchronization replication.
Popular storage controllers are comprised of Solid State Drive (SSD), SAS, SATA or a mix of those disk types. Different types of storage controllers vary in performance, price, reliability physical location and/or ownership.
For example, storage resources are typically owned and accessed locally or rented and accessed through the internet as in cloud storage. SSD is a data storage device that uses integrated circuit assemblies as memory to store data persistently.
SSD technology uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives. SSDs do not employ any moving mechanical components, which distinguishes them from traditional magnetic disks such as hard disk drives (HDDs) or floppy disks, which are electromechanical devices containing spinning disks and movable read/write heads. Compared with electromechanical disks, SSDs are typically less susceptible to physical shock, are silent, and have lower access time and latency, but are typically more expensive per unit of storage. Serial-attached Small Computer System Interface is also known as ANSI/INCITS 376-2003 and as Serial-attached SCSI (SAS). SAS is a method for accessing computer peripheral devices that employs serial means of digital data transfer over thin cables. The standard for SAS is provided by the American National Standard Institute. SAS enables business enterprises to access mass storage devices such as external hard drives. Serial ATA also known as Serial AT Attachment (SATA) is an interface for transferring data between host bus adapters to mass storage devices such as hard disk drives and optical drives. SATA was designed to replace the older parallel ATA (PATA) standard offering several advantages over the older interface: reduced cable size and cost, native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing protocol.
Another storage feature is data reliability and prevention of data loss. One technology for preventing data loss is Redundant Array of Independent Disks (RAID). RAID is a storage technology that combines multiple disk drive components into a logical unit. Data is distributed across the drives in one of several ways called “RAID levels”, depending on what level of redundancy and performance (via parallel communication) is required.
Another storage feature is storage efficiency. One technology for promoting storage efficiency is auto-tiering. Auto-tiering is the automated ongoing optimization of data across LUNs or file systems. Basically, data blocks are classified according to their usage. This classification is known as a heat scale with hot being extensive use and cold being minimal use. The hottest data blocks are tiered to higher performance media, while the coldest data is sent to lower cost, higher capacity drives.
Information technology (IT) was traditionally managed in-house, i.e. within a given organization. Cloud services now present alternatives to in-house IT solutions. Emerging representational state transfer (REST) protocols and appliances such as: Amazon S3 gateway and similar gateways and brokers use cloud services. With the development of cloud services the operational expense (OPEX) of IT has cut down. OPEX include the ongoing cost for running a product, business, or system as well as hidden costs of admin hours.
IT, whether in-house, over a cloud or as a combination of both, is typically managed in enterprises and other entities by administrators. Administrators typically play one of the following roles: a virtualization administrator, an application administrator and/or a storage administrator.

Some embodiments of the invention are herein described, by way of example only, with reference to the accompanying drawings. With specific reference now to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of embodiments of the invention. In this regard, the description taken with the drawings makes apparent to those skilled in the art how embodiments of the invention may be practiced.
In the drawings:
The present invention, in some embodiments thereof, relates to storage management and presentation and, more particularly, but not exclusively, to methods and/or systems for managing and/or presenting characteristics of storage pools.
The complexity of storage management is growing. One result of newly developed storage technologies, such as those listed above in the background section, are larger storage systems with heterogeneous components. The components of such storage systems may even be appliances, such as open-pNFS. System components may differ by version, vendor, optimization point and/or functionality among other features. While large storage systems built of heterogeneous component may be better in many senses and typically cheaper, their management can become more complex. The abundance of storage features also leads to a higher complexity of managing storage systems. Managing complex storage systems require higher skills which usually lead to higher operating expenses (OPEX).
Cloud has driven down storage pricing, pressuring IT administrators to become efficient and reduce its OPEX. IT administrators types, such as storage administrators and virtualization/application administrators, need to know characteristics of the storage they manage to promote efficiency. Lack of storage characteristics information as well as incomplete information, may lead to lower work efficiency, high cost and mistakes. For example, storage administrators occasionally make pooling mistakes.
Different roles within an entity may interact with storage resources: an application administrator, a storage administrator, a virtualization administrator, a system administrator and/or an application end user. Each of these roles may benefit from information about different storage characteristics to improve their work in terms of efficiency, cost etc. Moreover, a different detail level may benefit these different roles. For example: storage administrators may want to know the RAID level (RAID 0, 1, 5, 6, 10, 15, 50 and/or 60), whereas virtualization/application administrators may find this information too detailed, too technical and/or irrelevant for application/virtualization level storage management. Similarly, storage administrators may want to know the storage controller type: SSD, SAS, SATA, a gateway to cloud storage and/or a mix of those disk types, whereas virtualization/application administrators may not understand the performance, price and reliability tradeoff of these different media types. Virtualization/application administrators may require the assistance of storage administrators thereby wasting admin hours. Alternatively, virtualization/application administrators also acquire storage administration skills. The OPEX of these highly qualified administrators are typically higher than administrators with training in one of these storage subfields.
According to some embodiments of the present invention, virtualization/application administrators manage virtual storage pools. Storage resource pools and/or pools of volumes which are grouped according to a user defined requirements are referred to herein as virtual storage pools (vPools) Storage administrators create and export to virtualization/application administrators. vPools group and/or consume storage resources from one or more actual storage resources called storage pools. Storage resource pools may typically group resources of similar, though not necessarily identical storage volumes. vPools, on the other hand, may typically group and/or consume storage resources from heterogeneous storage resource pools according to storage needs of a storage consuming entity.
According to some embodiments of the present invention, storage resource pools group volumes. Tags are associated with the storage resource pools to simplify technical characteristics.
According to some embodiments of the present invention, there are provided methods and/or systems for virtual storage pools management. Actual storage resource pools and/or virtual storage pools, defined below, may improve an administrator's productivity, lower administration OPEX, simplify heterogeneous storage sources usage, and/or improve pooling reliability among other advantages. The characteristics of storage resource pools are presented in a productive manner for virtualization/application administrators, storage administrators and/or other roles. The characteristics of storage resource pools may be presented as tags summarizing their technical characteristics. Tag examples include SATA, RAID 5, Comp (which stands for compression) and Dedup (which stands for de-duplication technology). The tag list may be long and include many tags, as administrators may be interested in a varied and/or complete list of technical characteristics. The characteristics of virtual storage pools are presented in a productive manner for virtualization/application administrators, system administrators and/or organization administrators. The characteristics of virtual storage pools may be presented in user friendly terms summarizing less technical features. For example for: “GOLD Quality of Service”, “5 US dollars per Giga Byte” etc.
Optionally, these tags may contain free text as opposed to closed semantics.
Storage resources often need to be grouped into storage resource pools. Storage resources may include storage volumes and/or storage resource pools. By presenting relevant storage resource pools characteristics, storage resources grouping may be performed more efficiently and more reliably.
Optionally, grouping a plurality of quotas from one or more storage volumes is manually performed by a user (i.e. a storage administrator). Grouping recommendations for a given storage resource may be made.
Optionally, the presented characteristics that describe a storage resource pool may not have been provided by the user. Instead, they or a subset of them may have been auto-deduced from the characteristics of the storage volumes comprising the storage pool.
The characteristics contributing to the match between the storage volumes and the storage pool may be also presented. The change in characteristics of the storage pool after the addition of a new storage volume may also be presented thereby assisting in grouping quotas from storage volumes.
A virtual storage pool may group multiple storage resources which differ from each other by one of more technical characteristics, for instance by the average read latency. Understanding this from the technical characteristics of storage resources may be confusing. The methods and/or systems disclosed herein allow the technical characteristics to be simplified according to the needs of a specific entity.
Optionally, the technical characteristics are simplified in a generic manner regardless of a specific storage consuming entity, and then the storage resource pools and/or the virtual storage pools are matches with a storage consuming entity according to its needs.
The storage characteristics of a storage resource, such as a storage volume, a storage resource pool and/or a virtual storage pool, may be organized in two characteristics sets: a closed characteristic set of defined semantics (for example SSD) and/or an open characteristic set of free text (for example GOLD). The closed characteristic set may include a variable, for example X US Dollars per Giga Byte. X represents in this example an integer number. The closed characteristic set may be useful for storage administrators whereas the open characteristic set may be useful for virtualization/application administrators. Other storage roles may also benefit from one or more of these characteristic sets.
Optionally, storage resource pools are defined according to one or more binding rules. For example, the rule requires that the main disk type is SSD for any volume joining a specific storage resource pool grouped with that binding rule. Attempting to add a storage volume and/or a storage resource pool with one or more volumes of a different main disk type—results in some rejection behavior. The rejection behavior may be a soft warning (e.g. “Are you sure”) or a hard warning preventing the storage unit addition and/or initiating a fixing task.
Referring now to the drawings,
Optionally, such a predefined value list, a subset of that list and/or another modification over that list may also serve a storage resource pool 120, and/or a virtual storage pool 130.
Optionally, a value list of a virtual storage pool 130 may also include generalized less technical terms which may be typically used to characterize a virtual storage pool. These generalized terms may be easier to understand by non-storage administrators. The characteristics 110A-110D of a storage volume may be provided by a characteristics discovery module.
Optionally, storage volume characteristics include free text characteristics such as ˜3 USD per GB.
Optionally, the characteristics discovery module auto-discovers the characteristic of a storage volume 110, 112, 114, 116.
Optionally, storage volume characteristics 110A-110D are automatically provided as a result of an auto-discovery by a characteristics discovery module 825. Here, unlike in traditional mount options, storage volume characteristics 110A-110D may be read as part of listing the available storage volumes appliance 110, 112, 114, 116 for a storage resource pool 120. Proprietary protocols and/or vendor-specific plug-ins, such as for the open source libstoragemgmt library, may be used to extract the information. One optional embodiment of predefined characteristics and their values is provided below as Example 1. In this example, the list is implemented in a Java script object notation (JSON) format. Example 2 illustrates usage of free text characteristics. Example 3 illustrates a combination of predefined characteristics with free text characteristics.
Storage volumes 110, 112, 114, 116 are grouped into storage resource pools. Each storage resource pool 120, 121 have storage resource pool characteristics 120A, 120B, 121A, 121B. The storage resource pool characteristics 120A, 120B may be determined based on the storage volumes 110, 112 that are grouped with a specific storage resource pool 120. The number of storage resource pool characteristics 120A, 120B may be smaller than the number of storage volume characteristics 110A-110D. The storage resource pool characteristics 120A, 120B may be a subset of the storage volume characteristics 110A-110D.
Optionally, the types and/or values of storage resource pool characteristics 120A, 120B differ, in part and/or in whole from the types and/or values of the storage volume characteristics 110A-110D.
Optionally, it is desired for a user, such as a storage administrator, to translate the highly-technical storage resource pool characteristics and/or storage volume characteristics into something more intuitive at the storage volume level, the storage resource pool level and/or the virtual storage pool level. The simplified characterizations may assist the virtual storage pool management by the same user and/or by a different user such as an application/virtualization administrator.
Optionally, with lack of a convention, the simplified characterizations may be entity specific. An entity such as 140 may choose to characterize its storage resources and/or storage resource pools in terms such as price and performance metrics, for example “3 United States Dollars (USD) per GB” and “Silver Quality of Service (QoS)” respectively. Another entity may want to emphasize reliability, for instance by adding bronze, silver and gold service level agreement (SLA) characteristics tags, or even an actual variable such as 99.999% availability time.
Optionally, compiling storage resource pools based on multiple storage resource pool characteristics is an automated process. The quotas allocated from each virtual storage pool may be used in this process as well. For example, a virtual storage pool constructed from 25% “8 USD per GB” and 75% “1 USD per GB” is automatically shown as “2.75 USD per GB”. Storage resource pools may be defined, not only by auto-deduced and/or otherwise provided characteristics.
Optionally, the storage resource pool binding rules define a storage resource pool 120, 121. The storage resource pool characteristics 120A, 120B may be determined based on resource pool binding rules. The resource pool binding rules may be defined before, after and/or at the time of grouping one or more storage volumes with a given storage resource pool 120, 121. The resource pool binding rules may be defined regardless of the respective volume characteristics 110A-110D.
Optionally, resource pool binding rules may take into account the storage volume characteristics 110A-110D of storage volumes 110, 112, 114, 116 grouped with the storage resource pool 120, 121. One example of taking storage volume characteristics into account by resource pool binding rules is having resource pool binding rules be bound by the volume characteristic 110A-110D. For example, if a storage resource pool 120, 121 has a SSD volume 110 and a SATA volume 116, a resource pool binding rule cannot require SSD only for that storage resource pool 120, 121.
Optionally, when trying to define such a binding rule in the given storage volume 110,116 setting, a suggestion to lose a storage volume (116) that allows defining that resource pool binding rule would be made. Another example is creating a binding rule before adding storage volumes 110, 112, 114, 116 to a storage resource pool 120, 121. Upon addition of each storage volume 110, 112, 114, 116, its compliance with the binding rule is examined to prevent grouping mistakes.
Optionally, the resource pool binding rule and a non agreeing volume would co-exist and an error handling module 830 would remove such inconsistencies with and/or without manual user intervention. A binding rule associated with a storage resource pool may be defined in terms of storage volume characteristics and/or in terms of storage resource pool characteristics. A binding rule may be defined by a single characteristic and/or by multiple combined characteristics with or without logical relations between them such as if conditions.
A storage resource pool 121 may group one or more storage volumes 116 and have a list of characteristics 121A, 121B. A different storage resource pool 120 may have different storage resource pool characteristics 120A, 120B. The storage resource pool characteristics 120A, 121A and 120B, 121B may be chosen according to the storage needs of a storage consuming entity, application/virtualization administrator requirements, similarity to other storage resource pools 120, 121 etc. Storage resource pools 120, 121 are grouped into virtual storage pools 130. A user interface module 805, presenting and managing virtual storage pools, may assist in this grouping. For example, suggesting to group low-latency and low-cost storage pools with similar reliability level to create a cost-effective virtual storage pool. The assistance of the user interface module 805 may be performed by presenting virtual storage pool characteristics 130A, 130B along with storage resource pool characteristics 120A, 120B, 121A, 121B. The characteristics, simplified characteristics and/or tags of a virtual storage pool 130, may be a weighted average of the characteristics, simplified characteristics and/or tags of the storage resource pools 120, 121 grouped with that virtual storage pool 130. For example, creating a new virtual storage pool by grouping a set amount of quotas from a 2 USD/GB storage resource pool would result in a 2 USD/GB characteristic for the newly created virtual storage pool. Adding the same amount of quotas from a 6 USD/GB storage resource pool to the same virtual storage pool would change that characteristic to 4 USD/GB for that virtual storage pool.
Virtual storage pool characteristics 130A, 130B are associated with each virtual storage pool 130.
Optionally, the virtual storage pool characteristics 130A, 130B are simplified characteristics. Characteristics may be simplified by using common terms instead of technical terms. For example “fast disk” is a simplified version of SAS. Characteristics may be simplified by generalizing terms. For example, “highly reliable” is a simplified version of both RAID15 and RAID6 whereas “medium reliability” is a simplified version of both RAID1 and RAID5. The virtual storage pool characteristics 130A, 130B may be deduced from the respective storage resource pool characteristics 120A, 120B.
Optionally, virtual storage resource pool characteristics 130A, 130B may be defined independently of the respective storage resource pool characteristics 120A, 120B. Upon grouping a storage resource pool 120, 121 with a virtual storage pool 130, the virtual storage pool characteristics 130A, 130B may be compared with the storage resource pool characteristics 120A, 120B. Inconsistencies may prevent the addition of the storage resource pool 120, generate a warning and/or be handled by an error handling module 830.
Storage resource pool characteristics may be used to tag a virtual storage pool with predefined and/or on the fly tags. The content of a tag may be equal to a virtual storage pool characteristic, a virtual storage pool simplified characteristic and/or a generalized virtual storage pool characteristic. On the fly tags may have free text instead of closed semantics. A tag may be manually generated by a user, usually by the storage administrator, who understands and is able to translate the technical characteristics of the constructing storage pools. In some systems, these tags can be used in order to translate the semantics to a specific application/virtualization environment, in which a different terminology is used.
Reference is now made to
Optionally, the storage resource pool presentation 125 presents tags which represent one or more storage resource pools characteristics 125C-125D. The tags may be manually generated by a user, auto-deduced from the comprising storage volumes and/or a combination thereof.
Optionally, details on the tags of the comprising storage volumes can be viewed as well, for example by flipping the object to its back side, via the lower-right hand corner of the shape.
A storage resource pool characteristic may be inherited from the characteristics of all its comprising storage resources. Often times, though, not all storage resources have known characteristics and even the subset that is known may vary.
Optionally, the presented storage resource pool characteristics are deduced from the respective storage resource pool characteristics and/or the storage volume characteristics. The deduction may be performed according to the following logical rule: |p|<=|P| where P denotes a storage pool with |P| storage volumes, out of which a subset of p volumes hold known characteristics. Depending on the type of attribute, as exemplified below, Att_i is an attribute of P if:
Additionally or alternatively, other variations for deducing storage resource pool characteristics are used. GUI colors, brightness, shade, shape and/or texture may indicate how storage resource pool characteristics is deducted and/or how confident that conclusion is (e.g. is |p|<<|P| or nearly the same size).
Reference is now made to
The virtual pool presentations 135-137 may represent different units in the same organization and/or different organizations. The entity identity may be indicated 135D. The correspondence between the virtual storage pools 130 and the storage resource pools 120, 121 may be presented by visually associating the virtual storage pools presentations 135-137 with the storage pools presentations 125-127. The visual association may be indicated, for example, by color, shape, connecting lines, text and/or a combination thereof. Here, the horizontal bars 135A, 135B correspond to the presented storage resource pools 126-127. The horizontal bars 135A, 135B show the usage percentile of each quota from storage pool by that storage consuming entity as presented in 135.

Optionally, at least one grouping of a storage volume with at least one storage resource pool is proposed by a grouping module 815. The grouping is proposed according to at least one storage resource pool characteristic 124D and at least one storage volume characteristic 111A, 113A, 115A 117A and 111B, 113B, 115B, 117B.
Optionally, the match between at least one storage volume characteristic 111A, 113A, 115A 117A and 111B, 113B, 115B, 117B and at least one storage resource pool characteristic 124D is indicated.
Optionally, a first storage resource pool 120 is grouped with a second storage resource pool 121. Showing both storage volume characteristics 111A, 113A, 115A 117A and 111B, 113B, 115B, 117B and storage resource pool characteristics 122C-122D in the same presentation 300, 400 at the same time eases the process of grouping storage volumes 111, 113, 115, 117 with one or more storage resource pools 122-124.
Optionally, one or more storage volumes 111, 113, 115, 117 are grouped with a newly created storage pool 128. In this example, it is immediately clear that storage volume vol-A103 117 with its SATA 117A and RAID6 117B tags fits the Tier3-A1 storage resource pool 124 best. In one embodiment, such pooling recommendations are performed automatically and/or on demand by a grouping module 815. The recommendations may be based, for example, on the greatest number of matching storage volume characteristics 111A, 113A, 115A 117A and 111B, 113B, 115B, 117B, and/or calculating a weighted grade of matching storage volume characteristics 111A, 113A, 115A 117A and 111B, 113B, 115B, 117B, giving different weights to different types of storage volume characteristics 111A, 113A, 115A 117A and 111B, 113B, 115B, 117B.
Optionally, color, numerical values, graphs and other presentation schemes are used to mark the level of correlation between a chosen storage resource 111, 113, IR module 115, 117 and a matching candidate virtual storage pool 122-124, 128.
Optionally, storage volumes are grouped first to storage resource pools before grouping into virtual storage pools.
Optionally, storage volumes may be grouped directly into a plurality of different virtual storage pools.
In the example, depicted in 124 and 400, two storage volumes 115, 117 are chosen. Both have a SATA attribute, 115A, 117A which fits the target storage resource pool 124. The two chosen storage volumes 115, 117 are thus marked, for example with a color different from the other storage volumes 111, 113. The chosen storage volumes 115, 117 differ, however, on the RAID level 115B, 117B. The last chosen storage volume 117 is RAID6 117D, which fits the target virtual storage pool 124. The former chosen storage volume 115 is only RAID5. The last storage resource pool characteristic “RAID6” 124D is marked as strike-through, in order to capture a user's attention to the fact that the storage volume 115 may be grouped together with the storage resource pool 124, but at the cost of degrading the storage resource pools' characteristic 124D. If the user chooses to ignore the characteristic mismatch 115B, 124D and continue, he/she sees that the number of volumes increased 124B, and that the concluded attribute 124D has been degraded to RAID5.

Optionally, the grouping is performed according to one or more binding rules associated with a given storage resource pool 120,121. Next, at least one storage volume characteristic 110A-110D is associated 502 with said one or more storage resource pools 120, 121. The associated storage volume characteristic 110A-110D may now function as a storage resource pool characteristic.
Optionally, the associated storage volume characteristic 110A-110D is generalized before functioning as a storage resource pool characteristic. Next, a presentation for a user is generated 503 by a presentation creation module 810. The user may be a general administrator, storage administrator, virtualization administrator, application administrator, information technology (IT) person, a knowledgeable end user, a simple end user etc. The presentation presents at least one storage resource pool characteristic 120A, 121A, 120B, 121B. The storage resource pool characteristics 120A, 121A, 120B, 121B are, for example, main disk type, RAID type, auto tiering support, de-duplication support, compression support, remote copied (for disaster recovery) support, cost per storage capacity, cost per storage TOPS, reliability level, QoS level and/or SLA service level etc.
Optionally, the presentation is presented to a user on an electronic device such as a mobile phone, a terminal, a tablet, a laptop, a desktop, and/or a hand carried portable device.
Optionally, at least one tag representing at least one storage volume characteristic is generated 504. The tag may represent one or more storage resource pool characteristics. The tag may represent one or more storage volume characteristics.
Optionally, a tag is limited to a specific storage resource type such as a storage volume, a storage resource pool or a virtual storage pool.
Optionally, a tag is associated with one or more storage entity types: a storage volume, a storage resource pool and/or a virtual storage pool. A single tag is applied to one or many storage resource pools. The tag may be manually generated by a user. The tag may be automatically generated by a characteristics discovery module 825.
Optionally, at least one tag is associated 505 with one or more storage volumes.
Optionally, a storage resource pool characteristic is deduced according to grouping of one or more storage volumes and/or one or more storage resource pools.
Optionally, the deduction of storage resource pool characteristics is performed automatically by a characteristics discovery module 825. The characteristics discovery module 825 may further be configured to detect characteristics of a storage volume. The characteristics are optionally provided by a user through the user interface module 805.

Optionally, the association is performed according to one or more virtual storage pool characteristics. Next, as shown at 702, at one or more virtual storage pool characteristics are presented to a user in an electronic device.
Optionally, quotas from one or more storage resource pools are grouped with one or more virtual storage pools according to storage resource pool characteristics and/or virtual storage pool characteristics. The grouping may be performed manually by a user and/or automatically by a grouping module 815.
Optionally, the grouping is proposed according to at least one virtual storage pool characteristic and/or at least one storage resource pool characteristic 703.
Optionally, a match between at least one storage resource pool characteristic and one or more virtual storage pool characteristics is indicated.
The shared characteristics of a virtual storage pool may be deduced based on the characteristics of quotas from storage resource pools 120, 121 and/or storage volumes 110, 112, 114, 116 which are grouped with the virtual storage pool. The virtual storage pool characteristics 130A, 130B are displayed in association with the virtual storage pool 130. Virtual storage pools 130 may be allocated to storage consuming entities. The relationships between a virtual storage pool 130 and a storage consuming entity 140 may be presented by the presentation creation module 810.
Optionally, virtual storage pool tags are generated according to one or more storage resource pool characteristics and are associated one or more virtual storage pools.
Optionally, the tag generation and association may be performed automatically. For example since both storage resource pools have similar SLA tags and different QoS tags, some of the storage resource pools 120, 121 associated with a virtual storage pool 130 may not be characterized with respect to a specific storage resource pool characteristic 120A, 120B, 121A, 121B. The virtual storage pool characteristic 130A, 130B may be determined based on the characterized storage resource pools 120A, 120B, 121A, 121B, uncharacterized resource pools and/or both as exemplified with RAID6 in
Optionally, quotas from storage resource pools 120, 121 and/or virtual storage pools 130 are allocated to storage consuming entities application of a user end device 140.
Optionally, the allocation process is initiated by a request from a storage consuming entity 140. The request may include storage requirements. The match between the request and available storage resource pools 120, 121 and/or virtual storage pools 130 may be performed automatically. For example, a user defines that he/she wants a new storage pool with 30 GB quota having a main DiskType of SSD. The user does not specify a specific virtual storage pool and/or a specific storage resource pool. The grouping module 815 may look for such a match using the characteristics specified in the user's request.
Optionally, the storage requirements provided by a user are given in simplified characteristics terms. The simplified characteristics may be translated to the same type of characteristics used to describe the storage resource pools and/or virtual storage pools before matching storage resource pools 120, 121 and/or virtual storage pools 130. For example, a user asks for a new high performance virtual storage pool, which is a simplified characteristic of a virtual storage pool 130, and the grouping module 815 translates that to a request for 30 GB quota having a main DiskType of SSD. The match may proceed as in the previous example. The relationship between virtual storage pools and storage consuming entities may be many to many, one too many and/or one to one. These relationships may be presented to a user. The allocation may be initiated with an allocation request from a storage consuming entity. The allocation request may specify a virtual storage pool, exact characteristics of a virtual storage pool, minimum characteristics of a virtual storage pool, simplified characteristics of a virtual storage pool, tags of a virtual storage pool etc.
Storage resource pools 120, 121 and/or storage volumes 110, 112, 114, 116 which are grouped with a virtual storage pool 130 and/or storage pool 120, 121 may be dissociated from the virtual storage pool 130 and/or storage pool 120, 121. The virtual storage pool and/or storage pool characteristics 130A, 130B, 120A, 120B, 121A, 121B are updated accordingly upon dissociation.

Optionally, the system 800 comprises a characteristics discovery module 825 which detects storage volume characteristics and/or storage resource pools characteristics.
Optionally, the system 800 comprises an auto deduction module 835. The auto deduction module 835 may deduce a first tag for a first storage resource pool 120 based on a second tag of a second storage resource pool 121 if the storage resource pool characteristic(s) of the second storage resource pool resembles the storage resource pool characteristic(s) the first storage resource pool. The auto deduction module 835 may deduce tags for virtual storage pools 130 in a similar manner.
Optionally, each of the system's 800 modules, the user interface module 805, the presentation creation module 810, the grouping module 815 and the characteristics discovery module 825 interacts directly with the storage resources 820, such as a storage volume 110, 112, 114, 116, a storage resource pool 120, 121 and/or a virtual storage pool 130.
