    摘要: A method is used in managing replication and reservations. An amount of data storage space at a destination data storage location is determined that corresponds to expected successful completion of a data replication operation in which data is written to the destination data storage location. It is determined whether a thin provisioning reservation based on the amount can be made successfully at the destination data storage location. Based on whether the thin provisioning reservation can be made successfully, it is determined whether to proceed with the data replication operation.

    摘要: A method and system for use in managing data storage is disclosed. Data storage in a data storage system is managed. The data storage system comprises a first data storage tier and a second data storage tier configured such that the performance characteristics associated with one of the data storage tiers is superior to the other data storage tier. I/O activity is determined in connection with a data group stored on one of the first and second data storage tiers. It is determined whether to migrate the data group stored on the one of the first and second data storage tiers to the other data storage tier based on the performance characteristics associated with the other data storage tier and the determined I/O activity. The data group is migrated to the other data storage tier in response to determining to migrate the data group to the other data storage tier. The data group is processed in response to determining to migrate the data group to the other data storage tier such that fragmentation in connection with the data group is substantially reduced.

    摘要: Access to data storage is enhanced. A logical volume defines a set of block based data storage resources and is presented as a first volume. A virtual LUN portal mechanism serves as an alias for the first volume and is presented as a second volume. A block based data manipulation mechanism is configured to apply to a first I/O request directed to the second volume and not to a second I/O request directed to the first volume.

    摘要: A method and a system for use in managing tiering in a cache-based system is disclosed wherein the cache-based system comprises a first data storage tier and a second data storage tier configured such that the performance characteristics associated with one of the tiers is superior to the performance characteristics associated with the other tier. In at least one embodiment the method and system comprises collecting a first set of I/O activity data for at least one data unit located in a cache, wherein the at least one data unit is associated with a data group located on the first data storage tier; collecting a second set of I/O activity data for the data group located on the first data storage tier; analyzing the first and second set of I/O activity data; and based on the analysis and the performance characteristics associated with the second data storage tier, determining whether the data group should be migrated to the second data storage tier.
