Generally discussed herein are systems, devices, and methods for data management in a reverse content data network (rCDN). A component of the rCDN may include a memory to hold content received from a first sensor device of a plurality of sensor devices of the rCDN and first attributes that describe properties of the content. The component may include processing circuitry to receive second content from a second sensor device of the plurality of sensor devices, the second content including a plurality of second attributes that describe properties of the second content, and forward, in response to a determination, based on the first and second attributes, that there is insufficient space to store the second content on the memory, the second content to a node of the rCDN that is fewer hops away from a backend cloud than the component.

Data management in an edge network

Technologies for managing paravirtual network device queue and memory of a network computing device that includes multi-core processor, a multi-layer cache, a host, and a plurality of virtual machine instances. The host is assigned a processor core of the processor and may be configured to copy a received network packet to a last level cache of the multi-layer cache and determine one or more virtual machine instances configured to process the received network packet. Each virtual machine instance has been assigned a processor core of the processor and has been allocated a first level cache of the multi-level cache memory associated with the respective processor core. The host is additionally configured to inject an interrupt into each processor core of the determined virtual machine (s) which indicates to the virtual machine instance (s) that the received network packet is available to be processed.

Technologies for paravirtual network device queue and memory management

Disclosed herein are systems and methods for isolating input/output computing resources. In some embodiments, a host device may include logic to identify a Process Address Space Identifier (PASID) for a process or container of the host device and logic to associate the PASID with an individual queue pair of a hardware device of the host device, wherein the queue pair includes two complementary queues and wherein the queue pair is owned by the process or container upon association with the PASID. Other embodiments may be disclosed and/or claimed.

Systems and methods for isolating input/output computing resources

Generally discussed herein are systems, devices, and methods for managing content of an information centric network (ICN). A component of an ICN can include a memory including an extended content store that includes content from at least one other component of the ICN, and first attributes of the content, the first attributes including a content popularity value that indicates a number of requests for the content, and processing circuitry to increment the content popularity value in response to a transmission of a first content packet that includes the content, the first content packet transmitted in response to receiving an interest packet.

Data management in an information-centric network

Technologies for prioritized execution of storage commands by a data storage device include determining a priority of storage commands issued by a host and adding the storage commands to a queue of the data storage device based on the determined priority of the storage command. For example, the storage command issued by the host may be divided into sub-commands and added to a storage sub-command queue of the data storage device based on the determined priority of the storage command. The priority of the storage commands may be determined based on any suitable criteria including, for example, the host storage command queue storing the storage command, metadata associated with the storage command, the type or size of the storage command, and/or other aspects of the storage command, the host, and/or the data storage device.

Technologies for prioritizing execution of storage commands

Disclosed herein are systems and methods for isolating input/output computing resources. In some embodiments, a host device may include a processor and logic coupled with the processor, to identify a tag identifier (Tag ID) for a process or container of the host device. The Tag ID may identify a queue pair of a hardware device of the host device for an outbound transaction from the processor to the hardware device, to be conducted by the process or container. Logic may further map the Tag ID to a Process Address Space Identifier (PASID) associated with an inbound transaction from the hardware device to the processor that used the identified queue pair. The process or container may use the PASID to conduct the outbound transaction via the identified queue pair. Other embodiments may be disclosed and/or claimed.

Systems and methods for input/output computing resource control

Technologies for pacing transmission of network packets by a computing device to a remote computing device include performing a segmentation offload operation to segment a payload of a network packet into a plurality of network packet segments in response to a determination that a size of the payload is greater than a maximum allowable payload size. The computing device additionally determines a packet pacing interval and transmits the plurality of network packet segments to the remote computing device at a transmission rate based on the packet pacing interval.

Technologies for network packet pacing during segmentation operations

Providing a service in a storage system includes using a predicate that corresponds to a subset of storage objects in a set of storage objects stored in the storage system. The predicate is used to select or reject the objects to which the service is to be provided. The predicate is applied to the set of storage objects to obtain the subset of storage objects. The service is then invoked for the subset of storage objects selected according to the predicate. A trigger event causes invocation of the service. The trigger event may be periodic and/or may be a storage object lifecycle event, a storage object access related event, an event corresponding to a state change of the storage system, or an event that is external to the storage system. The trigger event may include the predicate being modified.

Unified framework for policy-based metadata-driven storage services

A method and computer program product for defining a first subnet for a first end portion of a physical network. The first subnet includes: a first NIC IP address, a first gateway IP address, and a first logical path connecting the first NIC IP address and the first gateway IP address. A second subnet is defined for a second end portion of the physical network. The second subnet includes: a second NIC IP address, a second gateway IP address, and a second logical path connecting the second NIC IP address and the second gateway IP address. A supernet is defined for a central portion of the physical network. The first subnet is coupled to the second subnet via the supernet to enable point-to-point routing of data through the physical network.

System and method for partitioning a network

A system, method, and computer program product for establishing a memory-mapped file, enabling the memory-mapped file data to be paged to a non-volatile storage medium, marking a portion of the memory-mapped file as protected, wherein a write to the memory mapped file throws a segmentation fault; receiving a write at the memory mapped file, throwing a segmentation fault; and handling the segmentation fault in a segmentation handler, where the handling comprises reading the information in the memory mapped file facility into the undo log, and writing the write IO to the storage medium.

Crash consistency

A computer implemented method, system, and program product for data consistency comprising establishing a memory-mapped file, enabling the memory-mapped file data to be paged to the non-volatile storage medium, receiving, at a consistency layer, a write IO; wherein the write IO corresponds to a space on the storage medium, issuing a read IO to the storage medium, wherein the read IO corresponds to the space on the storage medium to be overwritten by the write IO, writing the data of the read IO to a undo log and writing the write IO to the storage medium.
