A process control system software security architecture, that is more effective at preventing zero-day or other types of malware attacks, implements the use of “least privileges” when executing the applications and services run within a computer device. The least privileges based architecture separates “service” processes from desktop applications that run on behalf of a logged-on user by partitioning the global namespace of the software system into service namespaces and logged-on user namespaces, and by strictly controlling communications between the applications and services in these different namespaces using interprocess communications. Moreover, the security architecture uses custom accounts to assure that each service process has the least set of privileges that are needed for implementing its function regardless of the privileges associated with the calling application or user.

Randomly sending transactions across an interface can lead to idle interfaces and generally inefficient operations. Re-ordering transactions or data packets involves potentially changing the order of packet transmission to host devices. The re-ordering can ensure that each interface between a host device and the data storage device is saturated. The saturation is achieved by the re-ordering so that packet transmission is balanced across the interfaces. The balancing may be based on any number of factors such as namespace identification (ID), zone ID in a zoned namespace (ZNS) drive, submission and completion IDs, physical and virtual functions, and host addresses to name a few. The re-ordering and hence balancing results in packet level fairness and enables integration of asymmetric systems. In so doing, performance is optimized, reliability is maintained, and scalability is supported.

The one or more administrator operations for the particular storage device are transmitted to the first namespace and one or more data storage operations for the particular storage device are transmitted to the second namespace.

Enhancing data replication performance by preserving fastcopy-overwrite optimization for backups cloned across namespace subdivisions in a deduplication filesystem. A process keeps a key value pair for each of the files that are being cloned from the original namespace to a subcopy namespace. The key is the file handle of the file being cloned in the original namespace and the value is the handle of the cloned file in the subcopy namespace. When a subsequent generation backup of the same asset is cloned the basefile target file relationship is transferred as is to the new file in the subcopy namespace. This maintains the basefile to target file relationship after cloning to realize fastcopy-overwrite optimization benefits for the backup to the subcopy namespace.

The technology described herein is directed towards determining predicted and / or actual namespace resource consumption in an automated system for deployment, scaling, and management of containerized applications, such as in a Kubernetes® system. Given time series data representative of cluster-level resource consumption history at a percentage scale, resource consumption history for every namespace in the cluster at an absolute scale, and resource consumption history for each individual pod in the cluster at an absolute scale, multivariate time series forecasting with graph neural networks learns the hidden (dynamic and time variant) variable dependencies during a forecasting process that includes graph convolution followed by temporal convolution. The result is a forecast of a namespace's resource consumption.

Systems and methods for sharing a namespace of an ephemeral storage device by multiple consumers are provided. In an example, an NVMe driver of a virtual storage system deployed within a compute instance of a cloud environment facilitates sharing of the namespace by exposing an API through which the multiple consumers access an ephemeral storage device associated with the compute instance. During initialization processing performed by each consumer, for example, during boot processing of the virtual storage system, the consumers may share the namespace by reserving for their own use respective partitions within the namespace via the API and thereafter restrict their usage of the namespace to their respective partitions, thereby retaining the functionality provided by the multiple consumers when the host on which the compute instance is deployed has fewer ephemeral storage devices than consumers that rely on the availability of vNVRAM backed by ephemeral storage.

Page keys are formed in a key-value store (KVS) storing metadata of a filesystem. Page keys identify pages of trees within which namespaces of logical partitions are held. Leaf pages include first and second full keys for each file. First full keys index inodes. Second full keys index filenames. Inode keys are formed in the KVS. Inode keys identify inodes of the files. Metadata is embedded into the page and inode keys such that each page key includes an identifier of a logical partition, an identifier of a snapshot taken of a namespace of the logical partition, and a page number to a page tree holding the namespace. Each inode key includes the logical partition identifier, the snapshot identifier, and an inode number of an inode to a file. Upon damage to the namespace, queries are conducted of the KVS and the namespace is recovered based on the query results.

Methods, systems, and devices to support techniques for container registry credentials management are described. An operator executed across a set of clusters may manage credentials for multiple namespaces distributed across multiple clusters. For example, the operator may identify a configuration of a namespace (e.g., detect a creation of a configuration, detect an update to a configuration) and may provision the namespace within the container image registry using an application programming interface (API) call transmitted to the registry. The operator may retrieve one or more credentials associated with the namespace from the container image registry based on an operational mode (e.g., an application mode, an infrastructure mode). The operator may store the one or more credentials to a database associated with the cluster.

Embodiments relate to systems for generating identity records (e.g., authentication certificates) at a server for validating broadcast messages. The server may receive a request to generate an identity record, where the request may include a public key of a named entity device that is configured to broadcast messages. The server may generate the identity record using the private key of the server and transmit the generated certificate to a namespace server for storage. A policy consuming device configured to receive a broadcast message, which may be signed using the private key of the named entity device, subsequently accesses the namespace server for the identity record including the public key of the named entity device. The policy consuming device validates the authentication certificate using the server's public key and validates the broadcast message using the named entity device's public key.

A method is disclosed including establishing a browser session in response to receiving a request from a browser application in a public network. The browser session is assigned to a dedicated network service running in a dedicated network name space. Requests received from the browser application are proxied to a dedicated network service. A local web session in the dedicated network service authenticates a user of the browser application for access to at least one private webservice. A security client in the dedicated network service establishes a networking tunnel between the proxy and a remote gateway to the private network, thereby obtaining network access to the private webservice from the dedicated network name space. Within the dedicated network name space, proxied requests addressing the private webservice are forwarded over the networking tunnel to the private network.

Skills and skills metadata may be used to define a process for building a data center. Skills of one service may depend on skills corresponding to the same or different service. A dependency graph may be generated based on these dependencies. The graph may specify an order by which orchestration operations are to be performed to build the services, thereby building the data center. During execution of the process for building the data center, health states corresponding to the skills may be tracked (based at least in part on alarms and / or namespaces associated with the skills). When an unhealthy skill is identified, the system may traverse the dependency graph to identify a root cause (e.g., failed operations corresponding to a skill on which the unhealthy skill directly / indirectly depends). A notification and / or various options may be provided to address the unhealthy state of one or both skills.

Enhancing data replication performance optimization by maintaining parent-child file relationships when cloning an entire or portion of a first namespace to a second namespace for backups cloned across namespaces in a deduplication filesystem. The file copies may be made by either virtual synthetic (VS) copies that keep a one-way relationship between parent-child files or fast copy overwrite (FCOW) copies that keep a two-way parent-child relationship. Extended attributes are used as metadata for the files to indicate a path or recipe to generate the child file. The extended attributes for the cloned parent and child files are fixed to reference the second namespace so that a relative relationship between the parent and child files is maintained after cloning to the second namespace.

An energy estimator runs workloads to determine power consumed by processor cores in various power states and utilizations. This power consumption data is then used by an energy export agent for further calculations on different scenarios and cases. The energy export agent reads a total power consumption value from a CPU, data describing execution of processes from an operating system, and information regarding software components executing on the CPU from an orchestrator control plane. The agent uses data describing states of operating of the processor cores of the CPU and the total power consumption value to estimate power consumed by each processor core. Allocation and utilization of each processor core by a process and / or a container that spawned a process are then used to determine power consumption attributable to the process and / or container. A software hierarchy may be used to aggregate power consumption for applications, namespaces, or other software components.

The present invention is entitled "Data Aggregation in a ZNS Drive". The present disclosure as a whole relates to efficient data transfer management for partition append commands for a partition name space (ZNS). The ZNS storage device includes a memory device having a plurality of memory tube cores, and a controller coupled to the memory device. The controller receives a plurality of partition append commands, each partition append command being associated with a partition identifier that identifies a partition among a plurality of partitions; and extracts and aggregates data associated with each partition append command by the partition identifier in an append write buffer.
