Abstract: Improved techniques for applying performance controls in a data storage system based on overload correlations between units of managed storage objects (UMOs). When a performance indicator (e.g. response time) for a target UMO is outside an acceptable range, a competing UMO that potentially shares at least one potentially shared hardware component with the target UMO is identified. An overload correlation between the target UMO and the competing UMO is generated that indicates an amount of correlation between the performance indicator for the target UMO and a performance indicator for the competing UMO. A performance control is then applied to the throughput of the competing UMO that reduces the throughput of the competing UMO. The amount that the throughput of the competing UMO is reduced is based on the amount of overload correlation between the target UMO and the competing UMO.

Abstract: Control over the overall data cache hit rate is obtained by managing partitioning caching responsibility by address space. Data caches determine whether to cache data by hashing the data address. Each data cache is assigned a range of hash values to serve. By choosing hash value ranges that do not overlap, data duplication can be eliminated if desired, or degrees of overlap can be allowed. Control over hit rate maximization of data caches having best hit response times is obtained by maintaining separate dedicated and undedicated partitions within each cache. The dedicated partition is only used for the assigned range of hash values.

Abstract: An external storage resource pool associated with federated tiered storage is associated with at least one performance tier based on evaluated performance of the external storage resource pool. Performance of the external pool may be evaluated in terms of service level expectations or service level objectives. Workload pattern analysis or performance probability curves may be used to classify the external storage resource pool. Workload distribution may be determined by a margin analysis algorithm that matches workloads and storage resource pool performance characteristics.

Abstract: High performance storage resources are proactively deallocated when a storage group exceeds its service level objective. A load score is calculated for each unit of storage allocated from a high performance physical disk group. A minimum load score is determined that is the lowest load score calculated for the storage units allocated from the high performance disk group to the storage group. When the storage group service level objective is exceeded, a demotion threshold is calculated equal to a product of the minimum load score and a demotion range factor. A demotion set is determined made up of storage units allocated from the high performance disk group having load scores less than or equal to the demotion threshold. Host data stored on the demotion set is migrated to storage from a lower performance disk group, and the high performance units of storage in the demotion set are released for re-allocation.

Abstract: An efficient linear technique is used to determine allocation of tiered storage resources among data extents based on system performance and SLOs. Efficiency is achieved by first determining a system performance boundary condition via hardware performance modeling under desirable system performance zones. SLOs are then balanced and SLO achievement improved by exchanging workload activities among SG donors and SG receivers while system performance boundary conditions are maintained. Remaining unutilized capacity is the uniformly distributed to further improve SLO achievement.

Abstract: Described are techniques for configuring data storage. Criteria identifying limits is received for a plurality of storage tiers for one or more logical devices. The storage tiers include a first storage tier and one or more other storage tiers where the first storage tier is higher performing than the other storage tiers. First processing is performed to determine a first set of data portions of the logical devices to be stored on physical devices of the first storage tier subject to limits included in said criteria. First processing includes determining scores for data portions of the logical devices. Each score is calculated using one or more metrics including a first metric weighted based on an expected I/O size. The data portions are ranked in accordance with the scores. The first set of data portions stored in the first storage tier is selected based on the score ranking.

Abstract: A write operation writes first data to a target logical address range included in a first logical address range of a virtually provisioned device. It is determined that physical storage is not allocated for the target logical address range. First processing is performed to allocate a first portion of physical storage having a first corresponding logical address subrange that includes the target logical address range. The first portion is allocated from a physical device included in a first storage tier. The first processing includes selecting the first storage tier from multiple storage tiers in accordance with selection criteria including metrics characterizing an expected workload or level of activity for the first corresponding logical address subrange of the virtually provisioned device. Mapping information is updated to indicate that the first corresponding logical address subrange of the virtually provisioned device maps to the first portion of physical storage.

Abstract: Described are techniques for automated compression and/or decompression of data. Idle counters are received for data portions which indicate a level of inactivity with respect to idle criteria for the data portions. Compression criteria is received specifying conditions for determining whether a data portion is a candidate for data compression. The compression criteria includes a time compression threshold indicating a minimum amount of time that a data portion has been deemed idle with respect to said idle criteria. A data portion that qualifies as a candidate for data compression has an associated idle counter indicating an inactivity level that is greater than the time compression threshold. Processing determines whether a first data portion is a candidate for data compression in accordance with the compression criteria. If the first data portion is determined as a candidate for data compression, compression processing is performed for the first data portion.

Abstract: Described are techniques for performing storage optimizations in a system. The optimizations may include a data movement optimization. First processing may be performed by a first component to determine whether to automatically perform the data movement optimization for devices included in one or more data storage systems. The first component may be external with respect to the data storage systems and may not be included in any of the data storage systems. As a result of performing the data movement optimization, a first portion of data is automatically moved from a first of the devices to a second of the devices. The first and second devices may have different performance classifications. Additionally, automated discovery processing may be performed to determine performance classifications for devices of the data storage systems and/or determine physical device dependencies.
