US 11,899,950 B1 · Domain-specific initial configuration of high-speed memory

Abstract

Domain-specific initial high-speed memory configuration policies are created by analyzing workloads of storage systems deployed in each of a plurality of customer domains. Each domain-specific initial high-speed memory configuration policy specifies the size of both a mirrored policy region and a non-mirrored policy region. The sizes of the mirrored and non-mirrored policy regions are based on the respective proportion of read IO and write IO operations in the analyzed workloads of each customer domain. Each domain-specific initial high-speed memory configuration policy also specifies a distribution of slot sizes that should be created in each of the policy regions, based on read IO and write IO histograms created from the analyzed workloads in each customer domain. When a new storage system is deployed, the customer domain where the new storage system will be used is determined, and the high-speed memory configuration policy for the domain is applied to the storage system.

Dependent claims

A method of configuring initial high-speed memory of a newly deployed storage system, comprising:

creating domain-specific initial high-speed memory configuration policies for each of a plurality of customer domains, each domain-specific initial high-speed memory configuration policy specifying a first size of a mirrored policy region of the high-speed memory, a first distribution of slot sizes to be created within the mirrored policy region, a second size of a non-mirrored policy region of the high-speed memory, and a second distribution of slot sizes to be created within the second mirrored policy region;
determining a particular customer domain of the newly deployed storage system;
selecting one of the domain-specific initial high-speed memory configuration policies created for the determined particular customer domain;
and
applying the selected one of the domain-specific initial high-speed memory configuration policies to configure the high-speed memory of the newly deployed storage system.
