Method and apparatus for managing data in a cloud computing environment. In accordance with some embodiments, data updates are received to a multi-tier memory structure across a cloud network and stored as working data in an upper rewritable non-volatile memory tier of the memory structure. The working data are periodically logged to a lower non-volatile memory tier in the memory structure while a current version of the working data remain in the upper memory tier. The upper and lower memory tiers each are formed of rewritable memory cells having different constructions and storage attributes.

Data update management in a cloud computing environment

Method and apparatus for managing data in a memory. In accordance with some embodiments, a data object is stored in a first non-volatile tier of a multi-tier memory structure. A metadata unit is generated to describe the data object, the metadata unit having a selected granularity. The metadata unit is stored in a different, second non-volatile tier of the multi-tier memory structure responsive to the selected granularity.

Multi-tiered memory with different metadata levels

A data storage device receives a write data command and data. The data is stored in a buffer of the data storage device. The data storage device issues a command complete status indication. After the command complete status indication is issued, the data are stored in a primary memory of the data storage device. The primary memory comprises a first type of non-volatile memory and the buffer comprises a second type of non-volatile memory that is different from the first type of non-volatile memory.

Data protection for unexpected power loss

Method and apparatus for managing data in a memory. In accordance with some embodiments, input write data having a selected logical address are stored in a rewriteable non-volatile (NV) buffer. A copy of the input write data is transferred to an NV main memory using a sloppy write process. A verify operation is subsequently performed to verify successful transfer of the copy of the input write data to the NV main memory using a hash value generated responsive to the input write data in the NV buffer.

Non-volatile buffering to enable sloppy writes and fast write verification

Quality of service indicators are provided from a host via a host interface. The quality of service indicators relate to data stored in a non-volatile data storage via the host. Workload indicators related to the quality of service indicators are measured, and a weighting is assigned to the host in response to a correlation between the quality of service indicators and the measured workload indicators. The weighting is applied to the quality of service indicators when responding to data access requests from the host.

Assigning a weighting to host quality of service indicators

A system and associated method of using may generally have at least a mobile data storage device with a controller directing data to first and second tiers of memory. The first tier of memory can have at least boot data pre-fetched from the second tier of memory with the boot data including at least metadata and personalized user data.
