A technique manages data in a flash memory drive which includes single-level cell (SLC) flash memory and multi-level cell (MLC) flash memory. The technique involves performing, within the flash memory drive, data placement operations on data which has been written to the flash memory drive. The technique further involves, based on the data placement operations, storing hot data in the SLC flash memory. The technique further involves, based on the data placement operations, storing cold data in the MLC flash memory, the hot data being accessed more frequently than the cold data. Such hot data and cold data can be distinguished based on access frequency.

Described are techniques for testing software. The techniques may include identifying, at a first point in time, first code that has been modified, identifying, using first mapping information, a testing set of one or more test cases wherein the first mapping information identifies each test case of the testing set as a test case used to test the first code, running the testing set, generating coverage information in accordance with executing; analyzing the coverage information, generating second mapping information in accordance with said analyzing, and updating the first mapping information in accordance with the second mapping information.

Automated test coverage analysis, execution and reporting

A method is used for managing consistency groups in storage systems. A consistency group comprising multiple logical objects is created and multiple replicas of the consistency group are created. The consistency group is restored to one of the multiple replicas.

Restoring snapshots to consistency groups of mount points

A method performed by a storage management computer includes (a) receiving a set of storage profile definitions (SPDs) from an administrator of a data storage system over a user interface, each SPD of the set of SPDs including (1) a storage profile name and (2) a set of storage policies assigned to that SPD, (b) providing the storage profile names from the set of SPDs to an environment management application, the environment management application being configured to manage environments that use storage from the data storage system, (c) in response to providing, receiving a selection of a particular SPD from the environment management application to be used in connection with a particular environment, and (d) provisioning a unit of storage from the data storage system to the particular environment in accordance with the set of storage policies assigned to the particular SPD.

Techniques for abstract profile definition to support information hiding

A method is used in managing consistency groups in storage systems. A consistency group is created from a set of snapshot mount points. A snapshot mount point is a logical object accessible for using a replica of a logical volume. An operation is performed on the consistency group.

Managing consistency groups in storage systems

A heterogeneous data storage environment includes a first and second data storage system where the first data storage system includes management functionalities that are distinct from the management functionalities included by the second data storage system. A storage system management device is displays an environment management interface that dynamically changes based upon a user's need to manage either the first or second storage system. For example the storage system management device provides a default environment management interface for the first data storage system that includes a custom management display that allows the user to access the management functionalities associated with the first data storage system. The storage system management device dynamically changes the content of the environment management interface to provide a custom management display associated with the user selection of a second data storage system.

Environment management interface for management of a heterogeneous storage environment

A method is used in facilitating storage pool provisioning. A sequence of user interface screens is provided for configuring one or more physical devices of a data storage system for use in connection with provisioning a storage pool. By the sequence, a provisioning specification describing a RAID type and capacity is received. Best practices information describing one or more sets of data storage system best practices is received. By the sequence, a proposal is presented for performing configuration processing in connection with initialization of the data storage system to configure a first portion of the one or more physical devices for use with the storage pool. The best practices information is used in producing the proposal.

Facilitating storage pool provisioning

A method is used in restoring configurations of data storage system. A captured configuration is produced from capturing a configuration of a data storage system. The configuration includes a mapping of hierarchical objects. The captured configuration is used to help ensure that the configuration is not corrupted.
