摘要： Described is data storage system modeling. Received at a first data storage system is information representing a workload for I/O operations directed to a logical devices having storage provisioned on physical devices of a second data storage system. Information representing the workload may be obtained by performing discovery processing to discover performance characteristics of the physical devices of the second data storage system. Discovery processing may include receiving, at the first data storage system, I/O operations from a client directed to the set of one or more logical devices having storage provisioned on the physical devices of the second data storage system. The I/O operations are then issued to the second data storage system. In response, performance data is obtained at the first data storage system representing the workload for the plurality of I/O operations. Performance of the second data storage system is modeled in accordance with the workload.

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： A networked data storage system includes data movement logic and a virtual machine for executing a data management processing plan which is generated by a facility outside the storage array based on statistical information associated with extent level activity metrics provided by the storage array. Dynamically updated and automatically generated data management processing plans are provided to the storage array in the form of units of compiled byte code which the storage array is able to verify and execute using a virtual machine. The virtual machine interfaces with the environment in which it is embedded in a carefully constrained manner, thereby preventing clearly undesirable operations.

摘要： 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.

摘要： A system for normalizing capacity utilization within virtual storage pools includes collecting utilization statistics across individual storage devices that are members of a virtualized storage pool. Using the pool utilization level statistics, pool members may be assigned a score and, according to that score, may be marked as source, target or neutral members. Based on the scores of each pool member, data may be migrated among pool members, in particular, from source members to target members. The process may be iterative such that the statistics and scores may be used only to perform a fraction of the data movement that would be needed to normalize the storage pool before the scores are then recalculated. In this way, the system may dynamically adapt to changing conditions within the pool such as device additions, removals and inefficient striping of new data.
摘要翻译：用于规范虚拟存储池中的容量利用的系统包括在作为虚拟化存储池的成员的各个存储设备之间收集利用统计信息。使用池利用率级别统计，池成员可以被分配一个分数，并且根据该分数可以被标记为源，目标或中立成员。基于每个池成员的分数，可以在池成员之间迁移数据，特别是从源成员迁移到目标成员。该过程可以是迭代的，使得统计数据和分数可以仅用于执行在重新计算分数之前对存储池进行归一化所需的数据移动的一小部分。以这种方式，系统可以动态地适应池内的变化的条件，例如设备添加，删除和新数据的低效分条。
