Systems and methods are provided for using metadata to efficiently access object data from two or more storage components. Control circuitry receives a request from a host device to perform an operation on a uniquely identified object in a storage system comprising at least a first storage component and a second storage component. Control circuitry retrieves metadata information about the location of the object in store, wherein the metadata information comprises a first indication of a location of the object in the first storage component and a second indication of a location of the object in the second storage component. The objects in one or both of the first and second storage components are located based on the retrieved metadata information, and the requested operation is performed on the requested object.

Systems and methods for efficient storage access using metadata

A system comprises a partitioning module and a writing module. The partitioning module is configured to partition each of a plurality of solid-state disks into a plurality of blocks. Each of the plurality of blocks has a predetermined size. The writing module is configured to write data to one or more of the plurality of solid-state disks in a sequence starting from a first block of a first solid-state disk of the plurality of solid-state disks to a first block of a last solid-state disk of the plurality of solid-state disks, and subsequently starting from a second block of the first solid-state disk to a second block of the last solid-state disk. In each of each of the plurality of the plurality of solid-state disks, the second block is subsequent to the first block.

Adaptive cache memory controller

The present disclosure includes systems and techniques relating to customization of a bus adapter card. in some implementations, an apparatus includes a processor and a program memory, a bus adapter card coupled with the computing apparatus and configured to connect with a storage device, the bus adapter card computing a cache memory and a controller to cache in the cache memory data associated with the storage device, where the program memory includes a driver to communicate with the bus adapter card responsive to requests corresponding to the storage device, and the driver is configured to modify its communications with the bus adapter card responsive to information provided separate from the requests.

Customization of a bus adapter card

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, can perform data caching. In some implementations, a method and system include receiving information that includes a logical address, allocating a physical page in a non-volatile memory structure, mapping the logical address to a physical address of the physical page, and writing, based on the physical address, data to the non-volatile memory structure to cache information associated with the logical address. The logical address can include an identifier of a data storage device and a logical page number.

Data caching in non-volatile memory

The present disclosure includes systems and techniques relating to customization of a bus adapter card. In some implementations, an apparatus includes a processor and a program memory, a bus adapter card coupled with the computing apparatus and configured to connect with a storage device, the bus adapter card comprising a cache memory and a controller to cache in the cache memory data associated with the storage device, where the program memory includes a driver to communicate with the bus adapter card responsive to requests corresponding to the storage device, and the driver is configured to modify its communications with the bus adapter card responsive to information provided separate from the requests.
