A write command for a data block to write to a data volume is detected. A data volume address of the data block is determined. A superset range associated with the data volume address is determined. Upon determining that the written-to flag of the superset range is set: extend a previously established written-to subset range within the superset range to include the data volume address when it is determined that the data volume address is not within the previously established written-to subset range. Upon determining that the written-to flag is not set: set the written-to flag and establish a new written-to subset range within the superset range that includes the data volume address. Execute the write command.

Abstract: The present disclosure describes technologies and techniques for use by a data storage controller—such as a controller for use with a NAND or other non-volatile memory (NVM)—to provide a user-expandable memory space. In examples described herein, a customer may choose to purchase access to only a portion of the total available memory space of a consumer device, such as a smartphone. Later, the customer may expand the user-accessible memory space. In one example, the customer submits suitable payment via a communication network to a centralized authorization server, which returns an unlock key. Components within the data storage controller of the consumer device then use the key to unlock additional memory space within the device. In this manner, if the initial amount of memory the consumer paid for becomes full, the consumer may conveniently expand the amount of user-accessible memory.

Abstract: Techniques of implementing software filtered non-volatile memory in a computing device are disclosed herein. In one embodiment, a method includes detecting an entry being written to a guest admin submission queue (gASQ) by a memory driver of a virtual machine hosted on the computing device. Upon detecting the entry written to the gASQ by the memory driver, the command in the entry is analyzed to determine whether the command is allowed based on a list of allowed or disallowed commands. In response to determining that the command in the entry is not allowed, without sending the command to the non-volatile memory, generating an execution result of the command in response to the entry being written to the gASQ by the memory driver. As such, potentially harmful commands from the memory driver are prevented from being executed by the non-volatile memory.

Abstract: Apparatus and method for managing metadata in a data storage device, such as a solid-state drive (SSD). In some embodiments, a non-volatile memory (NVM) includes a population of semiconductor memory dies. The dies are connected a number of parallel channels such that less than all of the semiconductor dies are connected to each channel. A controller circuit apportions the semiconductor memory dies into a plurality of die sets, with each die set configured to store user data blocks associated with a different user. The controller circuit subsequently rearranges the dies into a different arrangement of die sets so that at least one die is migrated from a first dies set to a second die set. A map manager circuit is configured to establish an array of pointers in a memory to identify contiguous portions of map metadtata that describe user data stored in the at least one migrated die.

Abstract: Examples herein involve processing data in a distributed data processing system using an off-heap memory store. An example involves allocating a shared memory region of a shared memory to store attributes corresponding to a first partition of a distributed data system, and updating, in the shared memory region, the attributes corresponding to updates to the local data from process iterations of the first partition, such that a second partition of the distributed data system has access to the updated attributes.

The controller communicates with the host memory such that a plurality of pieces of data associated with operations of the memory device is buffered, based on the attribute information, in a plurality of host memory buffers allocated on the host memory. The controller communicates with the host memory such that first data corresponding to a first attribute group managed in the attribute information is buffered in a first host memory buffer among the plurality of host memory buffers and second data corresponding to a second attribute group different from the first attribute group is buffered in a second host memory buffer separate from the first host memory buffer.

Accordingly, the apparatus and method may include determining data rate mode selection criteria; selecting a data rate mode based on the data rate mode selection criteria; configuring a host interface for the data rate mode; and configuring an RCD input interface for the data rate mode. In one aspect, the apparatus and method further include activating a clock signal on the host interface and on the RCD input interface; transferring data from the host interface to the RCD input interface using the clock signal; and transferring the data from an RCD output interface using the clock signal in either 1N mode or 2N mode.

Abstract: In some embodiments, a system includes a memory system, a real-time computing device, and a controller. The real-time computing device stores data within a local buffer having a corresponding storage threshold, where the data satisfies the storage threshold, and where the storage threshold is based on a latency of the memory system and an expected rate of utilization of the data of the local buffer. The controller detects that the memory system should perform an operation, where the memory system is unavailable to the real-time computing device during the operation. In response to detecting that an amount of time for the operation exceeds an amount of time corresponding to the storage threshold, the controller overrides the storage threshold. The controller may override the storage threshold by modifying the storage threshold and by overriding a default priority for access requests of the real-time computing device to the memory system.

Abstract: Destaging data from a first tier data store to a second tier data store can be performed periodically and concurrently while processing user I/O operations. Each round of destaging can be delayed by certain amount (sleep time). A throttling factor can be used to compute the sleep time as a fraction of a base sleep time. The throttling factor can vary based on the usage level of first tier data store, and can be used to determine the destage frequency.

Abstract: Systems, apparatuses, and methods for implementing a distributed global ordering point are disclosed. A system includes at least a communication fabric, sequencing logic, and a plurality of coherence point pipelines. Each coherence point pipeline receives transactions from the communication fabric and then performs coherence operations and a memory cache lookup for the received transactions. The global ordering point of the system is distributed across the outputs of the separate coherence point pipelines. Device-ordered transactions travelling upstream toward memory are assigned sequence numbers by the sequencing logic. The transactions are speculatively issued from the communication fabric to the coherence point pipelines. Speculatively issuing the transactions to the coherence point pipelines may cause the transactions to pass through the distributed global ordering point out of order. Control logic on the downstream path reorders the transactions based on the assigned sequence numbers.

Abstract: Apparatuses, systems, methods, and computer program products are disclosed for archiving storage volume snapshots. An archive module determines at least one snapshot or point in time copy of data. A metadata module determines metadata for restoring a snapshot or point in time copy. A storage module replicates a snapshot or point in time copy and stores the replicated snapshot or point in time copy and metadata to a target storage location, such as one or more data files in a file system of one or more storage devices from a different vendor than a storage device from which the data was copied. In another embodiment, both the ability to archive a storage volume snapshot and restore a previously archived storage volume snapshot is provided.

Abstract: The first to third storage apparatuses each comprise an SVOL1, SVOL2 and PVOL. Even when the write command designates any of the PVOL, SVOL1 and SVOL2, at least one of the first to third storage apparatuses writes write target data according to the write command to the PVOL and then writes the write target data in parallel to the SVOL1 and SVOL2. Even if a read command designates any of the PVOL, SVOL1 and SVOL2, at least one of the first to third storage apparatuses reads read target data according to the read command from the PVOL.

A sub-total write counter associated with the first group of data blocks is reset. A value of the sub-total write counter indicates a number of write operations performed on the first group of data blocks since the first group of data blocks has been included in the second set of groups of data blocks. A wear leveling operation is performed on the first group of data blocks based on the sub-total write counter.

Abstract: Embodiments of systems and methods are provided for data storage in a tiered storage system comprising at least two storage tiers. A method comprises: providing storage information for each storage tier of the storage tiers to a user. The storage information comprising values of storage parameters, wherein the storage parameters comprise at least one of a storage quota limit of the user, usable storage capacity in the tier for the user based on the storage quota limit, and consumed storage capacity of the tier by the user. The storage information is used to move data between the storage tiers.

Abstract: Embodiments described herein are operable in a computing system. The computing system receives first and second commands (e.g., I/O commands). The computing system determines that the first command has a higher priority than the second I/O command, and queues the second command for servicing at a later time. The computing system services the first command, and services the second command after a timeout period based on performance degradation limit that decreases command processing performance of the computing system, overrides the timeout period, and increases a probability of executing the second command.
