Embodiment Construction

[0020] figure 1 is a block diagram of an exemplary network architecture 100 in which a quality of service manager 101 may be implemented. In the illustrated network architecture 100 , client systems 103A, 103B, and 103N and servers 105A and 105N are communicatively coupled to a network 107 . Quality of Service Manager 101 is shown as residing on servers 105A and 105N, but in other embodiments, Quality of Service Manager 101 may reside on more, fewer or different computers 210 as desired. exist figure 1 In, server 105A is also depicted as having directly attached storage devices 160A(1)-(N), and server 105N is depicted as having directly attached storage devices 160B(1)-(N). Servers 105A and 105N are also connected to a SAN fabric 170 that supports access by servers 105A and 105N, and thus client systems 103A-N, to storage devices 180( 1 )-(N) via network 107 . Smart storage array 190 is also shown as an example of a specific storage device accessible via SAN fabric 170 . I...

Abstract

Quality of service is provided to prioritized VMs and applications, based on the varied quality of different shared computing resources. Each VM or application has an associated priority. A quality rating is dynamically assigned to each shared computing resource. Requests for shared computing resources made by specific VMs or applications are received. For each specific received request, the current priority of the requesting VM or application is identified. In response to each received request, a specific shared computing resource is assigned to the specific requesting VM or application. This assignment is made based on the current priority of the requesting VM or application and the current quality rating of the shared computing resource, thereby providing quality of service to the requesting VM or application corresponding to its current priority.

Description

technical field [0001] The present disclosure relates generally to computing device virtualization, and more particularly to providing optimized quality of service to prioritized virtual machines and applications based on differing qualities of shared computing resources. Background technique [0002] Clusters are groups of computers that use redundant sets of computing resources to provide continued service in the event of failure of a single system component. More specifically, clusters eliminate single points of failure by providing multiple servers, multiple network connections, redundant data storage, and more. Clustered systems are often combined with storage management products that provide additional useful features, such as journaling file systems, logical volume management, multipath input / output (I / O) capabilities, and the like. For example, some storage management products, such as Veritas Volume Manager (Veritas Volume Manager) and Dynamic Multipathing (Dynamic...
