Embodiments include a load calculator, a workload analyzer, and a decision module. The load calculator generates an input/output (IO) record for an asset. The IO record includes a count of read operations and write operations corresponding to the asset from each of a plurality of sites. The workload analyzer collects the IO record and generates at least one of a write threshold and a read threshold. The decision module generates a request for at least one of a promotion and a copy of the asset in response to a determination that an operation has reached at least one of the write threshold and the read threshold for the asset.

Network asset management

The system includes a data synchronization module and a heat data module. The data synchronization module is configured to communicate with a first storage volume and a second storage volume to provide a backup for the first storage volume by synchronizing information from the first storage volume to the second storage volume. The information includes at least one of data chunks, heat map data, and first metadata relating to the first storage volume. The heat data module is coupled to the second storage volume to read the first metadata and the heat map data and adjust a location of at least one of the data chunks in the second storage volume based on the heat map data.

Heat map transfer in space-efficient storage

The system includes a plurality of storage volumes, a data synchronization module, a space-efficient storage module, and a heat data module. A second storage volume of the plurality of storage volumes includes a backup storage location for a first storage volume. The data synchronization module, coupled to the first storage volume and the second storage volume, provides a backup by synchronizing information from the first storage volume to the second storage volume during a synchronization event. The information includes data chunks, heat map data, and first metadata. The space-efficient storage module receives the information from the data synchronization module and allocates the information to the second storage volume in accordance with a space-efficient storage model. The heat data module reads the first metadata and the heat map data and adjusts a location of the data chunks in the second storage volume based on the heat map data.
