A processing device may generate a data encryption key configured to encrypt unique data within a clone of an encrypted data set and associated with a set of transaction identifiers of a transaction based file system. The processing device may further wrap the data encryption key with a wrapping key, create a cloned encrypted data set with the data encryption key, and store the wrapped data encryption key with the cloned encrypted data set indexed by at least one of the set of transaction identifiers.

Method and system for encrypting data

A method for retrieving a logical block, including receiving a request to read the logical block, and obtaining metadata associated with the logical block, wherein the metadata includes a replication type used to store the logical block and physical block locations in a storage pool for each physical block associated with the logical block. The method further includes obtaining power state information including a power state for the storage devices specified in the physical block locations, selecting a first set of physical block locations using the metadata, the power state information, and a power-usage selection policy, and generating I/O requests, where each I/O request specifies one of the first set of physical block locations. The method further includes issuing the I/O requests, receiving physical blocks in response to the I/O requests, and constructing the logical block using the physical blocks.

Method and system for power aware I/O scheduling

A method for priority-based allocation in a storage pool, involving receiving a first request to write a first data item in the storage pool, wherein the storage pool includes a first hybrid drive including a first plurality of metaslabs associated with a first storage type and a second plurality of metaslabs associated with a second storage type, selecting a first target metaslab from the first and second plurality of metaslabs based on a first plurality of allocation priorities, wherein the first plurality of allocation priorities are determined using a storage and power management policy, a storage characteristic, and a power characteristic associated with the first storage type and the second storage type in the first hybrid drive, allocating a first block to the first target metaslab, and writing the first block to the first target metaslab, wherein the first block includes a first portion of the first data item.
