Patent Application
20150032839
The present application relates generally to storage networks and, more particularly, to management and monitoring of storage entities in a storage network.
The creation and storage of digitized data has proliferated in recent years. Accordingly, techniques and mechanisms that facilitate efficient and cost effective storage of large amounts of digital data are common today. For example, a cluster network environment of nodes may be implemented as a data storage system to facilitate the creation, storage, retrieval, and/or processing of digital data. Such a data storage system may be implemented using a variety of storage architectures, such as a network-attached storage (NAS) environment, a storage area network (SAN), a direct-attached storage environment, and combinations thereof. The foregoing data storage systems may comprise one or more data storage entities configured to store digital data within data volumes.
Whereas the primary storage entity in a storage system cluster used to be a physical storage entity, such as a disk drive, a solid state drive, etc., recent trends have seen a rise in the number of virtual storage entities, such as storage systems that run on virtual machines with no specific hardware to support them, included in a storage system cluster. The addition of virtual storage entities increases the overall number of storage entities in the storage system cluster that must be managed. As a result, managing and monitoring an increasing number of storage entities has become a non-trivial task, as detailed below.
Conventional storage systems typically include a management server that is tasked with managing a designated storage system cluster. The management server is typically a computer within a storage management platform that monitors different objects. One such storage management platform is the System Center Operations Manager (SCOM) developed by Microsoft Corporation, although other storage management platforms are also available. In conventional systems, a storage system cluster with storage entities, either physical or virtual, is managed by only one management server within the storage management platform. Therefore, even though the storage management platform may include multiple management servers, a storage system cluster is managed by only one management server.
Many disadvantages are associated with these conventional systems. For example, if a management server becomes inoperable or is in need of an upgrade, a user must manually take down the inoperable management server, and must manually designate another management server to manage the storage entities that were previously being managed by the inoperable management server. In some situations, if a management server unsuspectingly becomes inoperable, all the data being monitored by the management server may be lost.
Other disadvantages associated with the convention systems are becoming apparent as a result of the increasing number of storage entities that a management server must manage. For example, because storage system clusters in conventional systems can only be managed by one management server, and because more and more virtual storage entities are being added to storage system clusters, an increasing number of conventional management server systems are reaching their maximum management load capacity.
For a more complete understanding of the present invention, reference is now made to the following descriptions taken in conjunction with the accompanying drawing, in which:
In embodiments, systems and methods are operable to deploy a group, which includes at least two management devices, to manage a plurality of storage entities in the storage network. Each management device of the group may have access to a shared management database. In operation according to embodiments, the storage entities may be managed by any one management device of the group. The systems may also be operable to identify a storage entity hierarchy for the plurality of storage entities. The systems may be further operable to determine at least one of a load or a health associated with a first management device of the group of management devices. The systems may also be operable to manage the plurality of storage entities with the group of management devices in accordance with the identified storage entity hierarchy and based, at least in part, on the determined at least one of a load or a health. In embodiments, managing the plurality of storage entities may include distributing the management of the plurality of storage entities across the group of management devices. Furthermore, the systems of embodiments may redistribute the management of the plurality of storage entities across the group of management devices based on the determined at least one of a load and health associated with at the first management device of the group. By managing the plurality of storage entities with a group of management devices, the robustness of systems in embodiments may be increased because more management devices are available to manage a storage entity. Other features and modifications can be added and made to the systems and methods described herein without departing from the scope of the disclosure.

Illustratively, nodes (e.g. network-connected devices 110 and 120) may be organized as one or more network elements (N-modules 112 and 122) and/or storage elements (D-modules 113 and 123) and a management element (M-host 111 and 121). N-modules may include functionality to enable nodes to connect to one or more clients (e.g. network-connected device 130) over computer network 101, while D-modules may connect to storage devices (e.g. as may implement a storage array). M-hosts may provide cluster communication services between nodes for generating information sharing operations and for presenting a distributed file system image for system 100. Functionality for enabling each node of a cluster to receive name and object data, receive data to be cached, and to communicate with any other node of the cluster may be provided by M-hosts adapted according to embodiments of the disclosure.
It should be appreciated that network 101 may comprise various forms, and even separate portions, of network infrastructure. For example, network-connected devices 110 and 120 may be interconnected by cluster switching fabric 103 while network-connected devices 110 and 120 may be interconnected to network-connected device 130 by a more general data network 102 (e.g. the Internet, a LAN, a WAN, etc.).
It should also be noted that while there is shown an equal number of N- and D-modules constituting illustrated embodiments of nodes, there may be a different number and/or type of functional components embodying nodes in accordance with various embodiments of the present disclosure. For example, there may be multiple N-modules and/or D-modules interconnected in system 100 that do not reflect a one-to-one correspondence between the modules of network-connected devices 110 and 120. Accordingly, the description of network-connected devices 110 and 120 comprising one N- and one D-module should be taken as illustrative only and it will be understood that the novel technique is not limited to the illustrative embodiment discussed herein.
Network-connected device 130 may be a general-purpose computer configured to interact with network-connected devices 110 and 120 in accordance with a client/server model of information delivery. To that end, network-connected device 130 may request the services of network-connected devices 110 and 120 by submitting a read or write request to the cluster node comprising the network-connected device. In response to the request, the node may return the results of the requested services by exchanging information packets over network 101. Network-connected device 130 may submit access requests by issuing packets using application-layer access protocols, such as the Common Internet File System (CIFS) protocol, Network File System (NFS) protocol, Small Computer Systems Interface (SCSI) protocol encapsulated over TCP (iSCSI), SCSI encapsulated over Fibre Channel (FCP), and SCSI encapsulated over Fibre Channel over Ethernet (FCoE) for instance.
System 100 may further include a management console (shown here as management console 150) for providing management services for the overall cluster. Management console 150 may, for instance, communicate with network-connected devices 110 and 120 across network 101 to request operations to be performed at the cluster nodes comprised of the network-connected devices, and to request information (e.g. node configurations, operating metrics) from or provide information to the nodes. In addition, management console 150 may be configured to receive inputs from and provide outputs to a user of system 100 (e.g. storage administrator) thereby operating as a centralized management interface between the administrator and system 100. In the illustrative embodiment, management console 150 may be networked to network-connected devices 110-130, although other embodiments of the present disclosure may implement management console 150 as a functional component of a node or any other processing system connected to or constituting system 100.
Management console 150 may also include processing capabilities and code which is configured to control system 100 in order to allow for management and monitoring of the network-connected devices 110-130. For example, management console 150 may be configured with a storage management platform, such as SCOM, to perform management of network-connected devices 110-130. In some embodiments, management console 150 may include functionality to serve as a management server within SCOM to monitor different data objects of the network-connected devices 110-130. Within a storage management platform environment, management console 150 may include processing capabilities to serve as a management server or as a management database, which may include a history of alerts, for the storage management platform environment. For additional management resources, system 100 may also include other management consoles 160 in communication with the network-connected devices 110-130 and management console 150.
In a distributed architecture, network-connected device 130 may submit an access request to a node for data stored at a remote node. As an example, an access request from network-connected device 130 may be sent to network-connected device 120 which may target a storage object (e.g. volume) on network-connected device 110 in storage 114. This access request may be directed through network-connected device 120 due to its proximity (e.g. it is closer to the edge than a device such as network-connected device 110) or ability to communicate more efficiently with device 130. To accelerate servicing of the access request and optimize cluster performance, network-connected device 120 may cache the requested volume in local memory or in storage 124. For instance, during initialization of network-connected device 120 as a cluster node, network-connected device 120 may request all or a portion of the volume from network-connected device 110 for storage at network-connected device 120 prior to an actual request by network-connected device 130 for such data.
As can be appreciated from the foregoing, in order to operate as a cluster (e.g. the aforementioned data storage system), network-connected devices 110-130 may communicate with each other. Such communication may include various forms of communication (e.g. point-to-point or unicast communication, multicast communication, etc.). Such communication may be implemented using one or more protocols such as CIFS protocol, NFS, iSCSI, FCP, FCoE, and the like. Accordingly, to effectively cooperate to provide desired operation as a logical entity, each node of a cluster is provided with the capability to communicate with any and all other nodes of the cluster according to embodiments of the disclosure.
According to an embodiment, the management devices 214a-214n may communicate with the storage network cluster 230 and the storage entities 232a-232n via the communication network 220. Communication network 220 may include any type of network such as a cluster switching fabric, the Internet, WiFi, mobile communications networks such as GSM, CDMA, 3G/4G, WiMax, LTE and the like. Further communication network 220 may comprise a combination of network types working collectively.
In one embodiment, the network cluster 230 comprising a plurality of storage entities 232a-232n may be managed by a management server 214, while in another embodiment, a storage entity 232 within cluster 230 may be individually managed by a management server 214. In yet another embodiment, a plurality of storage entities 232a-232n may be managed by a group of management devices 216 within the storage management platform environment 210. In embodiments, group 16 may include at least two management devices 214b-214c, while in other embodiments, group 16 may include more than two management devices 214b-214d, as shown in
In some embodiments, each management server 214b-214d within the group of management servers 216 may also be configured to have access to management database 212 and/or to each of the other management devices 214b-214d in the group 216. In other embodiments, at least one management server 214b-214d within the group of management servers 216 may be configured to have access to the management database 212 and/or to another management device 214b-214d in the group 216. With access to a management database 212, or another management server in the group 216, a management server 214b-214d may communicate with and/or share data with the management database 212 or another management server in the group 216. For example, in some embodiments a management device 214 with access to the management database 212 may receive instructions from the shared management database 212 to manage the plurality of storage entities 232a-232n. According to an embodiment, the management database 212 may be a separate management device than management devices 214, while in other embodiments the management database 212 may be a management device 214, either within the group 216 or not, or more than one management devices 214a-214n.
In an embodiment, each storage entity 232 may be manageable by any one management device 214 of the group 216. In other embodiments, a subset of the storage entities 232 may be manageable by any one management device 214 of the group 216. Therefore, in some embodiments, each storage entity 232 may be managed by one management device 214 of the group 216 at a given time. According to another embodiment, each storage entity 232 may be managed by more than one management device 214 of the group 216 at a given time.
According to an embodiment, the group 216 of management devices 214b-214d may be deployed to manage the plurality of storage entities 232a-232n of the storage network cluster 230. Prior to managing the storage entities 232a-232n as a group 216, the management devices 214b-214d of the group 216 may identify a storage entity hierarchy for the plurality of storage entities 232a-232n.
In some embodiments, once a management device 214b within a group identifies the storage entity hierarchy 300 for the plurality of storage entities 232a-232n, that particular management device 214b may become eligible to be included as part of the group 216 used to manage the plurality of storage entities. Therefore, in some embodiments, management of the plurality of storage entities 232a-232n with the group of management devices 214b-214d may be performed in accordance with the identified storage entity hierarchy 300. According to one embodiment, a management device 214d not having identified the storage entity hierarchy 300 for the plurality of storage entities 232a-232n may not be eligible for inclusion as part of the group of management devices 216 used to manage the plurality of storage entities 232a-232n. As an example, management devices 214b-214d may be deployed as a group of management devices 216 to manage the plurality of storage entities 232a-232n. If management devices 214b and 214c have identified the storage entity hierarchy 300 for the plurality of storage entities 232a-232n and management device 214d has not, then management of the plurality of storage entities 232a-232n may be distributed across management devices 214b-214c, but not management device 214d even though management device 214d has been specified to be part of group 216. When system 200 has configured management device 214d to identify the storage entity hierarchy 300 for the plurality of storage entities 232a-232n, then management of the plurality of storage entities 232a-232n may be distributed across each of management devices 214b-214d in the group 216.
Without being designated as part of a group of management devices 216 and having the functionality to identify the storage entity hierarchy 300, a management device may not be able to be included as part of the group of management devices 216 that manages a plurality of storage entities 232a-232n. For example, management servers 214a and 214n have neither been designated as part of the group 216, nor have they been given the functionality to identify the storage entity hierarchy, and therefore neither management server 214a nor 214n may be included within the group 216 that manages the plurality of storage entities.
In addition to managing the plurality of storage entities 232a-232n in accordance with the identified storage entity hierarchy 300, the management of the plurality of storage entities may also be based, at least in part, on a determined load and/or health of a management device 214b-214d of the group of management devices 216. For example, system 200 may be configured to determine a load associated with a management device 214b of the group of management devices 216. According to some embodiments, the load associated with a management device 214 may provide information related the number of storage entities 232a-232n being managed by the management device 214, the number of data objects being monitored by the management device 214, the amount of I/O traffic that is directed to or from the management device 214, or any other parameter which consumes processing resources of a management server 214. In other embodiments, the load parameter may also provide information related to the percentage of processing resources of a management device 214 are being consumed.
With the load determined, system 200 may include functionality to determine if the load associated with management device 214b of the group of management devices 216 has reached or is near a maximum capacity. If the load associated with management device 214b is determined to have reached or be near the maximum capacity, the management of the plurality of storage entities 232a-232n by the group of management devices 216 may be redistributed across the group 216 to balance the load associated with at least the first management device 214b in the group 216. In some embodiments, balancing the loads of the management devices 214b-214d of the group 216 may include removing the management responsibility of the first management device 214b for a first storage entity 232a, and managing the first storage entity by a second management device 214c in the group 216 that has available load capacity to manage one or more additional storage entities 232a-232n. As an example, in some embodiments, each storage entity 232a-232n may have an identifier associated with it that specifies which management device 214b-214d from the group 216 is managing it. Therefore, according to one embodiment, removing the management responsibility of the first management device 214b for the first storage entity 232a may include clearing the identifier associated with the first storage entity 232a. In addition, managing the first storage entity 232a by a second management device 214c may include updating the identifier associated with the first storage entity 232a that indicates which management device 214b-214d from the group 216 is managing the first storage entity 232a to indicate that the second management device 214c is now managing the first storage entity 232a.
As an example of balancing the load associated with at least one management device in the group 216, if one management device 214c of the group 216 is at 20% capacity and another management device 214d is at 95% capacity, then management of the storage entities 232a-232n may be redistributed among the group 216 such that management device 214c is at 60% capacity and management device 214d is at 55% capacity. As another example, if a management device 214c of the group 216 is managing 300 storage entities, which in some embodiments may be near the maximum capacity for a management device, then management of the storage entities 232a-232n may be redistributed among the group 216 such that management device 214c is now managing 20 storage entities.
In some embodiments, the storage entity hierarchy 300 for the plurality of storage entities 232a-232n may be defined to designate which storage entities 232a-232n in the storage network cluster 230 may be used to balance the load associated with at least one management device 214b-214d of the group 216. For example, in an embodiments, the storage entity hierarchy 300 may designate that top level unhosted storage entities may be used for load balancing. According to the embodiment, a storage entity 232a may be used for load balancing if the storage entity 232a is unhosted and there is no hosted storage entity in its path to the top most level. For example, according to the embodiment of
According to another embodiment, system 200 may include functionality to determine a health associated with a management device 214b of the group of management devices 216. In one embodiment, the health of a management device 214 may provide information detailing whether the management device 214 is properly managing and monitoring storage entities 232, is operating at a high performance level, has software bugs or viruses, is secure, is up-to-date, and the like. In one embodiment, determining the health of a management device 214 may include monitoring a plurality of conditions associated with the management device 214 that indicate that the management device 214 is healthy. In some embodiments, the conditions may be user-defined and modifiable.
With the health determined, system 200 may also include functionality to determine if management device 214b is not healthy based, at least in part, on the determined health associated with management device 214b. Determining that a management device 214 is not healthy may, according to one embodiment, include detecting, through monitoring of the management device 214, that a condition indicating a healthy management device 214 is not met. For example, according to one embodiment, a management device 214 may be determined to be not healthy if a condition requiring that the management device 214 monitor a particular storage entity is not met. That is, the monitoring of the management device 214 may detect that the management device 214 is not performing any management of any storage entities even though it has been configured to monitor particular devices, which may be an indication that the management device 214 is not healthy. In another embodiment, a management device 214 may be determined to be not healthy if it is detected, through monitoring of the management device 214, that the account credentials associated with the management device are out-of-date or incorrect. In some embodiments, monitoring of the management device 214 may indicate that all healthy conditions are met by the management device, which may indicate that the management device is healthy.
If the first management device 214b is determined to not be healthy, the management of the plurality of storage entities 232a-232n by the group of management devices 216 may be redistributed across the group 216. For example, if the first management device 214b is determined to not be healthy, the management responsibility of the first management device 214b for a first storage entity 232a may be removed, and a second management device 214c in the group 216 may be designated to manage the first storage entity 232a, where the second management device is a healthy management device 214. For example, according to one embodiment, removing the management responsibility of the first management device 214b for the first storage entity 232a may include clearing the identifier associated with the first storage entity 232a. In addition, designating a second management device 214c to manage the first storage entity 232a may include updating the identifier associated with the first storage entity 232a that indicates which management device 214b-214d from the group 216 is managing the first storage entity 232a to indicate that the second management device 214c is now managing the first storage entity 232a.
As in the case for load balancing, in some embodiments, the storage entity hierarchy 300 for the plurality of storage entities 232a-232n may be defined to designate which storage entities 232a-232n in the storage network cluster 230 may be managed by a first and a second management device. Therefore, in some embodiments, the storage entity hierarchy 300 identified prior to managing the plurality of storage entities 232a-232n with the group 216 may be the storage entity hierarchy 300 that defines which storage entities 232a-232n in the storage network cluster 230 may be managed by a first 214b and a second management device 214c of the group 216.
In some embodiments, managing a storage entity 232 with a management device 214 may include monitoring different objects of a storage entity 232, such as a network connection, data, such as directories, shared folders, software, and the like. These objects may, in some embodiments, be monitored and used to provide information regarding the load, operation, health, and the like of the storage entity 232 and a management device 214 monitoring the storage entity 232. In other embodiments, objects monitored by a management device may also include events or alerts occurring at the storage entities 232a-232n. In some aspects, a determination of the load associated with a storage entity 232 or a management device 214 may be made based on the monitored objects.
