A method of operating a storage appliance is provided. The method includes (a) in response to the appliance receiving a first command to perform a first storage operation on a first plurality of blocks, storing a command record for each block of the first plurality in a cache, each command record respectively indicating an address of that block; (b) upon flushing the command record for each block of the first plurality from the cache to persistent storage, storing data of that block at its indicated address; (c) in response to the storage appliance receiving a second command to perform a second storage operation on a second plurality of blocks, storing, in the cache, an aggregated command record that indicates the second storage operation and an address range of the second plurality, the second storage operation representing an identical change to all blocks of the second plurality; and (d) upon flushing the aggregated command record from the cache to the persistent storage, performing the storage operation indicated by the aggregated command record over the address range indicated by the aggregated command record.

In one embodiment, data communication apparatus includes a network interface including one or more ports for connection to a packet data network and configured to receive content transfer requests from at least one remote device over the network, a storage sub-system to be connected to local peripheral storage devices, and including at least one peripheral interface, and a memory sub-system including a cache and RAM, and processing circuitry to manage transfer of content between the remote device(s) and the local peripheral storage devices via the peripheral interface(s) and the cache, responsively to the content transfer requests, while pacing commencement of serving of respective ones of the content transfer requests responsively to a metric of the storage sub-system so that while ones of the content transfer requests are being served, other ones of the content transfer requests pending serving are queued in at least one pending queue.

A request to perform a write operation to write data at a memory sub-system is received. Responsive to the request to perform the write operation, the data is stored at a cache portion of cache memory of the memory sub-system. A duplicate copy of the data is stored at a write buffer portion of cache memory. An entry of the write buffer record is recorded that maps a location of the duplicate copy of the data stored at the write buffer portion to a location of the data stored at the cache portion of the cache memory. A memory operation is performed at the memory sub-system based at least in part on the write buffer record.

Methods, systems, and devices for using page line filler data are described. In some examples, a memory system may store data within a write buffer of the memory system. The memory system may initiate an operation to transfer the write buffer data to a memory device, for example, due to a command to perform a memory management operation (e.g., cache synchronization, context switching, or the like) from a host system. In some examples, a quantity of write buffer data may fail to satisfy a data size threshold. Thus, the memory system may aggregate the data in the write buffer with valid data from a block of the memory device associated with garbage collection. The memory system may aggregate the write buffer data with the garbage collection data until the aggregated data satisfies the data size threshold. The memory system may then write the aggregated data to the memory device.

The present disclosure provides a data storage method, an apparatus, and a storage medium, the method comprising: receiving a data storage request from a client, wherein the data storage request comprises data to be stored; determining a state of the data to be stored according to a least frequently used (LFU) and a least recently used (LRU) of the data to be stored, wherein the state is a cold data state or a hot data state; and determining a corresponding storage medium for the data to be stored according to the state of the data to be stored, and storing the data to be stored in the storage medium. The data storage method, the apparatus, and the storage medium provided in the present disclosure allow for reducing the probability of reading a disk and improving the stability of a system.

A memory system includes an interface circuit configured to connect to a host device, a controller electrically connected to the interface circuit, and a nonvolatile semiconductor memory electrically connected to the controller. The controller is configured to transmit a first response in response to a power supplied from the host device via the interface circuit, upon receipt of a first command from the host device after transmitting the first response, determine a status of data stored in the nonvolatile semiconductor memory, and transmit to the host device a second response including the determined status of the data stored in the nonvolatile semiconductor memory.

Optimizing generalized transfers between storage systems including identifying, by a first storage system, a request to transfer source data from the first storage system to a second storage system, wherein the first storage system implements a first storage architecture and the second storage system implements a second storage architecture; identifying difference information between the source data that is stored on the first storage system using the first storage architecture and existing data that is stored on the second storage system using the second storage architecture; and transferring, in dependence upon the difference information, a subset of the source data from the first storage system to the second storage system.

Systems, apparatuses, and methods related to a computing tile are described. The computing tile may perform operations on received data to extract some of the received data. The computing tile may perform operations without intervening commands. The computing tile may perform operations on data streamed through the computing tile to extract relevant data from data received by the computing tile. In an example, the computing tile is configured to receive a command to initiate an operation to reduce a size of a block of data from a first size to a second size. The computing tile can then receive a block of data from a memory device coupled to the apparatus. The computing tile can then perform an operation on the block of data to extract predetermined data from the block of data to reduce a size of the block of data from a first size to a second size.

Apparatuses, systems, methods, and computer program products are disclosed for balanced caching. An input circuit receives a request for data of non-volatile storage. A balancing circuit determines whether to execute a request by directly communicating with one or more of a cache and a non-volatile storage based on a first rate corresponding to the cache and a second rate corresponding to the non-volatile storage. A data access circuit executes a request based on a determination made by a balancing circuit.
