Some examples describe data locality solutions for a hyperconverged computing system. In an example, a data request may be received at a Virtual Storage Appliance (VSA) node amongst a plurality of VSA nodes in a hyperconverged computing system. A determination may be made whether a remapped logical block address (LBA) associated with the data request is included on a first mapping layer on the VSA node. In response to a determination that the remapped LBA associated with the data request is present on the first mapping layer of the VSA node, the remapped LBA may be used to resolve the data request. In response to a determination that the remapped LBA associated with another data request is not present on the first mapping layer of the VSA node, a second mapping layer on the VSA node may be used to resolve the other data request.

Local management of data stream throttling in data movement operations, such as secondary-copy operations in a storage management system, is disclosed. A local throttling manager may interoperate with co-resident data agents and/or a media agent executing on any given local computing device, whether a client computing device or a secondary storage computing device. The local throttling manager may allocate and manage the available bandwidth for various jobs and their constituent data streams—across the data agents and/or media agent. Bandwidth is allocated and re-allocated to data streams used by ongoing jobs, in response to new jobs starting and old jobs completing, without having to pause and restart ongoing jobs to accommodate bandwidth adjustments. The illustrative embodiment also provides local users with a measure of control over data streams—to suspend, pause, and/or resume them—independently from the centralized storage manager that manages the overall storage system.

A computer-implemented method includes an act of configuring hardware to cause at least a part of the hardware to operate as a double data rate (DDR) memory controller, and to produce a capture clock to time a read data path, where a timing of the capture clock is based on a first clock signal of a first clock, delay the first clock signal to produce a delayed first clock signal, adjust the delay such that at least one clock edge of the delayed first clock signal is placed nearer to at least one clock edge of at least one data strobe (DQS), or at least one signal dependent on a DQS timing, and produce a modified timing of the capture clock based on the delay of the first clock signal.

An apparatus includes a processor component of a first node device caused to receive data block encryption data and an indication of size of an encrypted data block distributed to the first node device for decryption, and in response to the data set being of encrypted data: receive an indication of the quantity of sub-blocks within the encrypted data block, and a hashed identifier for each data sub-block; use the data block encryption data to decrypt the encrypted data block to regenerate data set portions from the data sub-blocks; analyze the hashed identifier of each data sub-block to determine whether all data set portions are distributed to the first node device for processing; and in response to a determination that at least one data set portion is to be distributed to a second node device for processing, transmit the at least one data set portion to the second node device.

Techniques are provided for multi-tier write allocation. A storage system may store data within a multi-tier storage environment comprising a first storage tier (e.g., storage devices maintained by the storage system), a second storage tier (e.g., a remote object store provided by a third party storage provider), and/or other storage tiers. A determination is made that data (e.g., data of a write request received by the storage system) is to be stored within the second storage tier. The data is stored into a staging area of the first storage tier. A second storage tier location identifier, for referencing the data according to a format utilized by the second storage tier, is assigned to the data and provided to a file system hosting the data. The data is then destaged from the staging area into the second storage tier, such as within an object stored within the remote object store.

Systems and methods of the present disclosure are directed to defining a data store format for storing state information related to border-gateway protocol (BGP) routing information base (RIB) entries, BGP Neighbor Tables, intermediate system-intermediate system (IS-IS) adjacencies, Link-State Databases, Interface information, Chassis information, etc in a binary format. A brick data store (BDS) system can define tables, table properties, objects and attributes for an application in the system using configuration files expressed in Java Script Object Notation (JSON). The data format can be uniform across inter-process communication, file and in-memory representation.

Methods, systems, and computer readable media can be operable to facilitate the updating of memory at a device based upon a custom command file. In embodiments, update or configuration codes or data may be delivered to a device within a download package, and the download package may include a command file. The command file may identify one or more operations that are to be carried out on the memory of the device, and each respective one of the one or more operations may be associated with a subset or portion of the memory of the device. The device may identify the one or more operations and the one or more associated memory areas from the command file, and the device may carry out the one or more operations on only those areas of the device memory that are identified from the command file as being associated with the operations.

A semiconductor apparatus may include a fuse cell array, an address generation circuit, a control circuit, and a command generation circuit. The fuse cell array may store a fail address. The address generation circuit may generate a copy address according to test information containing the fail address. The control circuit may control a repair operation including enabling a copy start signal according to the test information and storing the fail address in the fuse cell array according to a copy done signal. The command io generation circuit may generate an address and a plurality of commands for a data copy operation according to the copy start signal and enable the copy done signal when the data copy operation is completed.

An aspect of validating vHBA fabric zoning in a SAN includes receiving, by a computer processor, a request for data corresponding to zones in a storage area network to which an initiator in a host system computer has access; instantiating, by the computer processor, a virtual host bus adapter interface on the host system computer; and transmitting, via the virtual host bus adapter interface, the request to a fabric controller in the storage area network. An aspect also includes receiving a current active zone set from the fabric controller; parsing the current active zone set for the initiator; identifying, from the parsing, each of the zones in the current active zone set to which the initiator is indicated; and displaying the identified zones via the computer processor.

A data storage device utilized for storing a plurality of data includes a memory and a controller. The memory includes a plurality of blocks, and each of the blocks includes a plurality of physical pages. The controller is coupled to the memory and maps the logical pages to the physical pages of the memory. When the controller detects that a first logical page of the logical pages is a currently-used logical page, it detects whether or not the second logical page which belongs to the last logical page of the first logical page is a currently-used logical page in order to find what is truly the last currently-used logical page.
