摘要： Techniques are described for processing a data operation that writes first data to a data portion currently stored on first physical storage of a first storage tier of a data storage system, including storage tiers each having a different performance ranking relative to other storage tiers. Second physical storage is allocated from one of the storage tiers for storing the first data written to the data portion. This one storage tier is selected independent of the first storage tier. The first data is stored in a cache and destaged from the cache to the second physical storage. A single merged copy of data for the data portion is formed. Based on an activity level of the data portion, a target tier is selected for storing the single merged copy of data for the data portion.

摘要： Described are techniques for performing data storage optimizations. A data storage optimizer on a first data storage system connected to a set of other data storage systems receives performance classification information. The first data storage system includes a first set of storage devices of a first performance classification. The set of other data storage systems includes a second set of storage devices of a second performance classification different from the first performance classification. A write operation is received from the host to write first data to a target address of a virtually provisioned device. It is determined that physical storage is not currently allocated for the target address of the virtually provisioned device. A first portion of physical storage is allocated for storing the first data. The first portion of physical storage is included in a storage device of the second set having the second performance classification.

摘要： 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.

摘要： To facilitate both minimal allocations and adaptive allocations, two sets of storage group policies are defined—one policy setting minimal allocation values for storage group access to storage resources and one policy setting maximal allocation values for storage group access to storage. In addition, a set of priority weights is specified that is used to balance access to storage tiers across storage groups. Upon existence of contention for storage resources, minimum allocation values for storage groups are determined based on the priority weights for the storage groups, resulting in threshold values being set to enable at least partial access to storage resources for all storage groups without requiring priority weighting of the activity density distributions of the competing storage groups. Allocations other than the minimal allocations are provided based on relative activity density distribution of storage extents between groups.
摘要翻译：为了方便最小分配和自适应分配，定义了两组存储组策略 - 一种策略设置用于存储组访问存储资源的最小分配值，以及一个策略设置用于存储组访问存储的最大分配值。此外，还指定了一组优先级权重，用于平衡对存储组间存储层的访问。在存储资源的争用存在时，基于存储组的优先级权重来确定存储组的最小分配值，导致阈值被设置为使得能够至少部分地访问所有存储组的存储资源，而不需要优先权重竞争存储组的活动密度分布。基于分组之间的存储范围的相对活动密度分布提供除最小分配之外的分配。

摘要： 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.

摘要： Storage requirements of one or more applications may be serviced by a mix of different disk technologies across one or more storage tiers. According to the system described herein, desirable or optimal mixes of the different disks may be determined and used in the efficient and cost-effective modification or upgrade of storage arrays. For example, whereas SATA drives may be the most cost effective per gigabyte of storage, some applications may not be able to operate based on SATA performance characteristics. On the other hand, flash drives, which may have high performance characteristics, may be too expensive to be used exclusively in a storage array. The system described herein provides a tool that allows for optimal planning of storage resources in a multi-tier storage environment responsive to workload data of a storage array and based on performance characteristics and costs of the storage resources.

摘要： Synchronization of data layouts and resource utilizations at one or more remote replica sites with the workload and data tiering decisions being made at the primary site allows for an efficient and effective workload support transfer in the event of site failover from a primary site to a remote site. Relevant data access information about workload being supported at the primary site is collected and from that raw information, characterized data access information is generated that condenses the raw data access information or otherwise provides relevant encapsulated information about the raw data access information. The characterized data access information is transmitted to the one or more remote sites allowing each remote site to make its own independent decisions on how best to utilize its available resources to match the performance requirements currently being supported by the primary site.
