Technology is described for a profile-based lifecycle management for data storage servers. The technology can receive a profile, monitor events emitted by devices of the data storage system, determine based on the monitored events that a device of the storage system matches the indicated condition, and perform the action corresponding to the indicated condition, wherein the action includes managing data stored by the data storage system. The received profile can indicate a condition and an action corresponding to the condition.

Technology is described for actively responding to data storage traffic. The technology can provide an application program interface; receive, via the application program interface, from an application, a command to query a data storage attribute associated with a virtual data storage component; query the associated virtual data storage component; and return to the application a value for the data storage attribute.

Profile-based lifecycle management for data storage servers

An alignment data structure is used to map a logical data block start address to a physical data block start address dynamically, to service a client data access request. A separate alignment data structure can be provided for each data object managed by the storage system. Each such alignment data structure can be stored in, or referenced by a pointer in, the inode of the corresponding data object. A consequence of the mapping is that certain physical storage medium regions are not mapped to any logical data blocks. These unmapped regions may be visible only to the file system layer and layers that reside between the file system layer and the mass storage subsystem. They can be used, if desired, to store system information, i.e., information that is not visible to any storage client.
