Abstract
Techniques for translating Service Level Agreement (SLA) policy into storage controller requirements within a cloud storage environment are presented. System resource metrics for a storage controller are derived. The SLA policy is defined in terms of SLA parameters. Heuristics are used to translate the SLA parameters into defined percentages of system resources for the storage controller, which are compared to the system resource metrics and adjustments are updates are made as needed.
Claims20
A method implemented in a non-transitory machine-readable storage medium and processed by one or more processors of a machine configured to perform the method, comprising:
- defining, on the machine, a Service Level Agreement (SLA) policy for a tenant in a multi-tenant storage cloud environment in terms of performance parameters;
- acquiring, from the machine, controlling factors that affect resource performance for a storage controller assigned to the tenant, wherein the storage controller logically assembled in the multi-tenant storage cloud environment for the tenant as a tenant storage machine specific to the tenant, and the multi-tenant storage cloud environment servicing multiple other tenants, wherein acquiring further includes deriving an equation for the performance parameters based on the controlling factors and correlating past heuristic data for the storage controller with the performance parameters;
- and
- evaluating, from the machine, the equation for the performance parameters using measurements collected for the storage controller and using the past heuristic data for calculating resource requirements and selecting resources and resource configurations of the storage controller that meet or exceed the performance parameters based on the calculated resource requirements.
A method implemented in a non-transitory machine-readable storage medium and processed by one or more processors of a machine configured to perform the method, comprising:
- translating, on the machine, a Service Level Agreement (SLA) policy into specific resources and resource configurations for a storage controller of a tenant in a multi-tenant storage cloud environment, wherein the storage controller is logically assembled in the multi-tenant storage cloud environment for the tenant as a tenant storage machine specific to the tenant and the multi-tenant storage cloud environment service multiple other tenants, and wherein translating further includes deriving an equation for performance parameters based on the controlling factors for the storage controller, correlating past heuristic data for the storage controller with the performance parameters, and evaluating the equation for the performance parameters using measurements collected for the storage controller and using the past heuristic data for calculating resource requirements and selecting the specific resources and resource configurations for the storage controller that meet or exceed the performance parameters based on the calculated resource requirements;
- and
- dynamically adjusting, on the machine, the resource configurations to improve performance with respect to the SLA policy.
A system, comprising:
- a cloud storage environment having one or more processors, memory, and storage, the cloud storage environment situated in a cloud environment and accessed over a network;
- and
- the memory configured with a Service Level Agreement (SLA) policy translator implemented as executable instructions that process on the one or more processors of the cloud storage environment;
- wherein the SLA policy translator is configured to define a SLA policy in terms of performance metrics and then acquire control factors that affect performance of a storage controller for a tenant of the cloud storage environment, and wherein the SLA policy translator is further configured to derive an equation for the performance metrics based on the control factors, correlate past heuristic data for the storage controller with the performance metrics, evaluate the equation for the performance metrics using measurements collected for the storage controller and using the past heuristic data for calculating resource requirements, and select specific resources and resource configurations for the storage controller that meet or exceed the performance metrics based on the calculated resource requirements, and the SLA policy translator configured to configure the specific resources with the resource configurations, and wherein the storage controller logically assembled in the cloud storage environment for the tenant as a tenant storage machine specific to the tenant and the cloud storage environment servicing multiple other tenants.
