Abstract: Example implementations relate to virtual persistent volumes. In an example, a manifest of a containerized application to which a virtual persistent volume is allocated is read from a container orchestrator. An application data store profile that matches information of the manifest is identified from among a plurality of application data store profiles that each include storage parameters preconfigured for a respective application type. The virtual persistent volume is modified according to the identified application data store profile.

Abstract: Systems and methods are provided for encrypting data in a memristor array. The data may be scrambled by multiplying an input data unit by another data unit, by multiplying each element of a first data unit by a different instance of a second data unit. The process continues until all elements of the first data unit are multiplied by a different instance of the second data unit. The elements of the data units may be represented by resistive values of a memristor array. The result of all of the above multiplication of different instances of the second data unit are a new set of data units. All of the resulting data units are added together by adding the currents associated with values of the memristors representing the resulting data units. The operation may be performed as a finite field computation, with the memristor array.

Abstract: A system divides non-volatile memory of a plurality of storage devices into physical extents which comprises chunks. The system allocates slabs associated with the storage devices, wherein a respective slab comprises extents from different storage devices and further comprises stripes. A stripe comprises a chunk from each extent of the respective slab. The system updates, in a first data structure, an entry which indicates: a slab number for the respective allocated slab; and a storage device identifier and an extent number for each extent in the respective allocated slab. Responsive to receiving a write request, the system obtains a first stripe from a pre-allocated list which includes the allocated slabs. The system searches, based on stripe information associated with the first stripe, the first data structure to obtain a physical location in a storage device to which to issue the write request.

Abstract: In some examples, a system performs data deduplication using a deduplication fingerprint index in a hash data structure comprising a plurality of blocks, wherein a block of the plurality of blocks comprises fingerprints computed based on content of respective data values. The system merges, in a merge operation, updates for the deduplication fingerprint index to the hash data structure stored in a persistent storage. As part of the merge operation, the system mirrors the updates to a cached copy of the hash data structure in a cache memory, and updates, in an indirect block, information regarding locations of blocks in the cached copy of the hash data structure.

Abstract: Examples disclosed herein relate to performing a software update on a network device forming a MC-LAG. In an example, a software update onto a first network device and a second network device may be downloaded. The first network device and the second network device may form a MC-LAG that may provide a redundant connectivity to a network device in a network. A shutdown of routing protocols on the first network device may be performed. Each of the routing protocols may advertise a maximum metric on the first network device, leading to a recalculation of network routes by the network device. The first network device may be updated with the software update. Until the software update on the first network device is complete, network traffic on the network may be routed through the second network device.

Abstract: 5G provides for interworking with the 4G/LTE networks, which provides for mobility of user equipment between the 5G and 4G/LTE networks. Mobility from 5G to 4G/LTE requires deregistering user equipment from the 5G core network (5GC) by communicating a deregistration notification from the Evolved Packet Core (EPC) to the 5GC. Systems and methods disclosed herein provide for an optimized deregistration process through avoidance of redundant deregistration notification traffic injected into the 5G network by utilizing 4G/LTE connectivity information to determine whether or not to inject deregistration notifications into the 5G network.

Abstract: Disclosed herein are network information collectors, methods, computer-readable media, and systems for generating network traffic statistics. For example, the network appliance is to receive, via a network, an accumulating map from a network appliance device, wherein the accumulating map comprises a condensed and aggregated version of web traffic flow information to the network appliance device; receive, via the network, additional accumulating maps from other network appliance devices; populate an accumulation map database with the accumulating map and the additional accumulating maps; and generate a report of the network traffic statistics hosted by the network appliance device and the other network appliance devices.

Abstract: In some examples, a system includes a processing entity and a memory to store data arranged in a plurality of bins associated with respective key values of a key. The system includes a cache to store cached data elements for respective accumulators that are updatable to represent occurrences of the respective key values of the key, where each accumulator corresponds to a different bin of the plurality of bins, and each cached data element has a range that is less than a range of a corresponding bin of the plurality of bins. Responsive to a value of a given cached data element as updated by a given accumulator satisfying a criterion, the processing entity is to cause an aggregation of the value of the given cached data element with a bin value in a respective bin.

Abstract: A control circuit for a plurality of metal-oxide semiconductor field-effect transistors (MOSFETs) in a bridge circuit for rectifying an alternating current (AC) input to generate a direct-current (DC) output includes first and second high side controls and first and second low side controls for providing gate voltage signals to respective MOSFETs in the bridge circuit. Dead time controls are provided for establishing dead time intervals between activation of complementary MOSFETs in the bridge circuit. The low side controls provide gate voltage signals having sloped edges and the dead time controls include Zener diodes having reverse bias thresholds for determining the duration of the dead time intervals.
