The present disclosure relates to a method and apparatus for measuring performance of a storage system. The method comprises: causing one or more entities to execute a task set comprising multiple tasks, each of the multiple tasks being used for accessing the storage system; obtaining an indicator set of the storage system based on a result of the execution, the indicator set comprising one or more indicators for indicating performance of the storage system; and adjusting the task set based on the indicator set, for subsequent execution by the one or more entities. The method can be executed iteratively. By means of the present invention, workloads for the next round's execution can be intelligently improved according to execution results after each round's execution of workloads, so that performance of the storage system can be obtained more pertinently and efficiently so as to better utilize the storage system.

Measuring performance of storage system

Techniques are disclosed for generating data provenance associated with a computing system. For example, a method comprises the following steps. Information associated with the execution of a given process in a given computing environment in accordance with a given process data set is captured. A provenance data set is generated based on the captured information. The generated provenance data set comprises one or more states associated with one or more execution components of the given computing environment that existed during execution of the given process, the one or more execution components comprising one or more virtual machines and one or more storage units. At least a portion of the generated provenance data set may be utilized to revert the computing environment back to the one or more states associated with the one or more execution components of the given computing environment that existed during the execution of the given process.

Data provenance in computing infrastructure

A data storage system includes: one or more storage nodes configured to attach to a computer network to provide network-attached storage for the computer network; a first application programming interface providing data storage functionality at a file level in the one or more network-attached storage nodes for a first set of application programs operating in the computer network; and a second application programming interface providing data storage functionality at a level other than the file level in the one or more network-attached storage nodes for a second set of application programs operating in the computer network, wherein the second application programming interface comprises one or more native representational state transfer-based application programming interfaces.

Techniques for constructing virtual storage networks for tenants with quality-of-service delivery. In one example, a method comprises the following steps. One or more virtual storage networks are constructed respectively for one or more tenants of a data storage system. Each of the one or more virtual storage networks is tenant-managed and is configured such that logical resources of the tenant-managed virtual storage network are isolated from physical resources used to implement the logical resources.

Constructing virtual storage networks for multiple tenants with quality-of-service delivery

Techniques for delivering and measuring storage quality-of-service to virtual machines in a distributed virtual infrastructure. In one example, a method comprises the following steps. A controller obtains quality-of-service data from at least a portion of components of a distributed virtual infrastructure, wherein the components of the distributed virtual infrastructure comprise one or more storage units, one or more processing units, and one or more switches operatively coupled to form the distributed virtual infrastructure. The controller manages at least one input/output request throughout a path defined by at least one of the one or more processing units, at least one of the one or more switches, and at least one of the one or more storage units, based on at least a portion of the collected quality-of-service data.

Storage quality-of-service control in distributed virtual infrastructure

Techniques are disclosed for managing assets, such as virtual assets, in a computing system implemented with distributed virtual infrastructure. In one example, a method comprises the following steps. Operational information associated with a plurality of virtual assets in a data center is obtained in a trusted manner. The data center is implemented via a distributed virtual infrastructure. At least a portion of the operational information for at least a portion of the plurality of virtual assets in the data center is reported. The operational information reported is operational information pertaining to one or more virtual assets that the data center provides for a tenant of the data center. The obtaining and reporting steps are performed by at least one processing device operating as a virtual asset manager operatively coupled to the distributed virtual infrastructure.
