A computer-implemented method, system, and computer-readable media are disclosed herein. In embodiments, the computer-implemented method may entail receiving, by a data service, live data associated with an entity. The entity may be, for example, a customer of the data service. The method may further include determining that a dual-queue node assigned to the entity is uninstantiated on the data service. As a result, a dual-queue node associated with the entity may be instantiated on the data service. The dual-queue node may be instantiated by initializing a live data queue, of the dual-queue node, in which to place the live data for processing and a stale data queue, of the dual-queue node, in which to store a persistent backup of the live data. The method may then route the live data to the dual-queue node. The dual-queue node may then process the live data. Additional embodiments are described and/or claimed.

A method begins by a plurality of dispersed storage network (DSN) units of a DSN determining to perform a DSN level task for a range of DSN addresses. The method continues with each of the plurality of DSN units executing a scoring function using one or more properties of the range of DSN addresses and one or more properties of each of the plurality of DSN units to produce a scoring resultant. The method continues with each of the plurality of DSN units identifying a DSN unit of the plurality of DSN units to execute the DSN level task based on the scoring resultant. The method continues with the identified DSN unit executing the DSN level task for the range of DSN addresses.

Various embodiments are generally directed to techniques for reducing the time required for a node to take over for a failed node or to boot. An apparatus includes an access component to retrieve a metadata from a storage device coupled to a first data storage module of a first node during boot, the metadata generated from a first mutable metadata portion and an immutable metadata portion, and the first metadata specifying a first address of a second data storage module of a second node; a replication component to contact the second data storage module at the first address; and a generation component to, in response to failure of the contact, request a second mutable metadata portion from a network protocol module of the first node and generate a second metadata from the second mutable metadata portion and the immutable metadata portion, the second mutable metadata portion specifying a second address of the second data storage module.

Systems and methods are disclosed to provide packet copy management for service chain processing within virtual processing systems. A packet manager virtual machine (VM) controls access to shared memory that stores packet data for packets being processed by service chain VMs operating within a virtual processing environment. For certain embodiments, the packet manager VM is configured to appear as a destination NIC (network interface controller), and virtual NICs (vNICs) within the service chain VMs are configured to process packet data using pointers to access the packet data within the shared memory. Once packet data is processed by one service chain VM, the next service chain VM within the service chain is able to access the processed packet data within the shared memory through the packet manager VM. Once all service chain processing has completed, the resulting packet data is available from the shared memory for further use or processing.

The disclosed computer-implemented method for backing up heterogeneous virtual environments may include (1) identifying a request to back up a virtual machine executing on a host system, (2) creating a storage map of a virtual storage environment of the virtual machine by (a) identifying, from the host system, a virtual disk file that stores data for the virtual machine and (b) identifying, from a guest system operating within the virtual machine, one or more virtual storage devices that store data for the virtual machine, and (3) creating a unified backup of the virtual machine based on the storage map of the virtual storage environment by coordinating a backup operation of the virtual disk file with a backup operation of the virtual storage device. Various other methods, systems, and computer-readable media are also disclosed.

A device includes a microcontroller, memory including secure memory to store a private key, a set of registers, and an authentication engine. The set of registers includes a write mailbox register and a read mailbox register, and message data is to be written to the write mailbox register by a host system. The message data includes at least a portion of a challenge request, and the challenge request includes a challenge by the host system to authenticity of the device. The authentication engine generates a response to the challenge, where the response includes data to identify attributes of the device and a signature generated using the private key. The authentication engine causes at least a portion of the response to be written to the read mailbox register to be read by the host system.

A reconfigurable compute fabric can include multiple nodes, and each node can include multiple tiles with respective processing and storage elements. A first tile in a first node can include a processor with a processor output and a first register network configured to receive information from the processor output and information from one or more of the multiple other tiles in the first node. In response to an output instruction and a delay instruction, the register network can provide an output signal to one of the multiple other tiles in the first node. Based on the output instruction, the output signal can include one or the other of the information from the processor output and the information from one or more of the multiple other tiles in the first node. A timing characteristic of the output signal can depend on the delay instruction.

A converged infrastructure management system includes a first converged infrastructure system chassis housing a backplane. A plurality of managed devices are connected to the backplane and include at least one compute device, at least one network device, and at least one storage device. A management device is connected to the backplane and includes a display and an input device that are accessible on an outer surface of the management device. The management device includes a management engine that is configured to retrieve management information from any of the plurality of managed devices through the backplane and display the management information that was retrieved on the display. The management engine is also configured to receive instructions through the input device and, in response, modify the management information that is displayed and send the management information that has been modified through the backplane to the management device associated with that management information.

Technology is disclosed for enabling scene-based variable compression (“the technology”). In some embodiments, the technology can receive an indication of a compression level for a first content type, wherein the compression level specifies a tolerance level for lossy compression; receive a request for content, the content having at least two portions, wherein a first portion has first content of the first content type and the second portion has second content of a second content type, a first compression method associated with the indicated compression level and a second compression method associated with a different compression level. The technology can transmit the content, wherein the first portion of the content was compressed using the first compression method and the second portion was compressed using the second compression method.

Examples are disclosed for access to a storage device maintained at a server. In some examples, a network input/output device coupled to the server may allocate, in a memory of the server, a buffer, a doorbell, and a queue pair accessible to a client remote to the server. For these examples, the network input/output device may assign an Non-Volatile Memory Express (NVMe) namespace context to the client. For these examples, indications of the allocated buffer, doorbell, queue pair, and namespace context may be transmitted to the client. Other examples are described and claimed.
