A data storage server may store a data packet generated by a client in a first server memory prior to the data packet being migrated to a third server memory of the data storage server by a server controller in response to a server data migration module. The data packet may be moved to satisfy a quality of service agreement between a host and the client. The data packet can be proactively copied to a second server memory by the server controller in response to the migration of the data packet from the first to the third server memories.

Data storage server with multi-memory migration

A data storage system can provide low cost and optimized performance with a cartridge housing multiple separate data storage devices and each of the data storage devices being concurrently engaged by a device player. The device player may have a processor configured to analyze mechanical performance of each data storage device and data performance of data resident in each data storage device.

Low cost data storage system

Apparatus and method for managing data in a hybrid data storage device. In some embodiments, the hybrid data storage device has a hard disc drive (HDD) controller circuit coupled to non-volatile rotatable storage media and a solid state drive (SSD) controller circuit coupled to non-volatile solid state memory. A local memory stores a map structure which identifies logical addresses of current version data sets stored in the solid state memory. A top level controller circuit operates responsive to the map structure to direct a selected host data transfer access command to the HDD or SSD controller circuit. The map structure may be arranged as a plurality of discrete logical address sequences, where a gap is provided between each adjacent pair of the discrete logical address sequences in the map structure.

Internal data transfer management in a hybrid data storage device

Apparatus and method for managing data in a hybrid data storage device. In some embodiments, the storage device has a hard disc drive (HDD) controller circuit coupled to non-volatile rotatable storage media and a solid state drive (SSD) controller circuit coupled to non-volatile solid state memory. A local volatile memory has separate HDD and SSD partitions respectively accessible by the HDD and SSD controller circuits. A top level controller circuit performs a cleaning operation to transfer a data set from the non-volatile solid state memory to the rotatable storage media by issuing a read command to the HDD controller circuit to retrieve the data set to the HDD partition, transferring the data set from the HDD partition to the SSD partition, and issuing a write command to the SSD controller circuit to write the data set from the SSD partition to the non-volatile solid state memory.

Hybrid data storage device with partitioned local memory

A data storage area of a data storage device can be used to communicate information between the data storage device and an external device or software. In some examples, configuration data stored within the data storage area can be used to determine a subset of data to copy or move from a first data storage medium to a second data storage medium. The data storage area can be a unique partition and the data storage device can locate partition information to determine a location of the partition. The data storage device can then use the partition to store data for two-way communication between the data storage device and an external system, device, or software.

Direct hinting for a memory device

A data storage system may be configured at least with a primary memory that is coupled to a host via a controller and coupled to at least one external interface. The controller may be adapted to passively partition a secondary memory into cache and user memory space regions in response to the secondary memory engaging the at least one external interface and the cache region can be allocated as cache for the primary memory by the controller.

Data storage system with passive partitioning in a secondary memory

A hybrid data storage device includes a solid-state memory device, a disc-type memory device and a hybrid data storage device controller in communication with the solid-state memory device and the disc-type memory device. The hybrid data storage device controller is configured to receive Non-Volatile Memory Host Controller Interface (NVMHCI) commands from a host and use logic to make decisions for the optimization and efficient performance of the solid-state memory device and the disc-type memory device.

NVMHCI attached hybrid data storage

In a particular embodiment, a system includes a controller adapted to determine a data transfer rate associated with at least one data stream to be written to a storage media and to selectively activate at least one of a first memory and a second memory based on the data transfer rate to record the at least one data stream.

Storage device and controller to selectively activate a storage media

A circuit may be configured to increase the data retention reliability of non-volatile solid state memory (NVSSM) by writing a parity block, which can contain user data pages and parity data pages. A circuit can also be configured to store the parity data pages based on whether the user data pages in the block have been filled, on elapsed time, or during a power down event.

Parity data in solid state memory

In a particular embodiment, a system is disclosed that includes a controller to read data from and write data to a first storage medium. The controller is adapted to monitor logical block addresses (LBAs) of each read operation from the first storage medium and to selectively store files associated with the monitored LBAs that are less than a predetermined length at a second storage medium to enhance performance of applications associated with the LBAs.

Storage device with manual learning

In a particular embodiment, a storage device is disclosed that includes a solid-state storage media. The storage device further includes a read/write circuit including an error correction coding (ECC) encoder/decoder adapted to write data and associated ECC information to the solid-state storage media without performing a read-verify operation.
