Abstract: System and method embodiments for placement of Centralized Discovery Controller (CDC) services on a switching network fabric are disclosed. Nodes on the switching network fabric are categorized into leader nodes, e.g., spine switches, and follower nodes, e.g., leaf switches. The CDC services are divided into centralized CDC services and distributed CDC services, which has direct connections to endpoints for seamless horizontal scaling of endpoints. The centralized CDC services are placed on a leader node and the distributed CDC services are placed among the follower nodes. Operations of the CDC services are monitored. In case of a node failure, CDC services deployed on the failed node are moved or transferred to one or more other nodes that have the same role as the failed node. Implementation of the CDC service placement embodiments enables seamless horizontal scaling for endpoints and provides capability for more visibility and monitoring of endpoint.

Abstract: Systems and methods provide modern storage networks, such as those utilizing a non-volatile memory express over Fabric (NVMe-oF) system, with connectivity options that meet low-latency and high-throughput demands. In certain embodiments, this is accomplished by enabling network entities to acquire and utilize network information, including discovery information, to dynamically manage routing tables and build routes, e.g., to allow a host to send out frames through desired interfaces to reach target destinations. An automated IP routing update service allows for dynamically creating, reading, updating, and deleting functions of otherwise static IP routing table entries to streamline functions in the storage fabric.

Abstract: A design of an infrastructure deployment is used for new deployments or as part of an addition to an existing deployment. Because of the complexity of modern infrastructure deployment designs, these designs are subject to a number of problems that are too complex and extensive for manual detection of potential issues. Furthermore, these infrastructure deployments are often critical infrastructure, which means their timely deployment and proper functioning are necessary. While improper design can cause functional problems, selection of an infrastructure element that suffers a supply chain delay so as to delay deployment can be as negatively impactful as a poor design. Accordingly, embodiments herein help automate the analysis of an infrastructure deployment design. In one or more embodiments, a trained neural network receives as input a design and analyzes it to classify a particular issue or issues of the design.

Abstract: Systems and methods provide zero-configuration provisioning for modern storage networks such as those utilizing a non-volatile memory express over Fabric (NVMe-oF) system. In various embodiments, this is accomplished by leveraging discovery information, such as multicast Domain Name System (mDNS) information, to locate subsystems in a network and to explicitly and dynamically specify target destinations without a Centralized Discovery Controller (CDC) client having to modify its routing table.

Abstract: An information handling system for obtaining composed information handling systems includes resource set components and a system control processor. The system control processor makes an identification, based on monitoring of a resource set component of the resource set components, of an operation event; in response to the identification: makes a determination that the operation event is not immediately remediable based on the monitoring of the resource set component; in response to the determination: modifies the monitoring of the resource set component to obtain refined operation data for the resource set component; and performs an action set, based on the refined operation data, to modify operation of the resource set component.

Abstract: An organizational graph and a microservice graph can be generated. For two neighboring microservices, a combined organizational distance can be determined based on a distance for respective workers of each microservice in the organizational graph. The combined organizational distance can be used to determine a priority for a connection between the two microservices, and chaos testing can be performed on that connection based on its priority.

Abstract: A switching fabric role assignment system includes a plurality of switch devices coupled together in a switching fabric. A first switch device included in the plurality of switch devices receives an endhost device identification communication from an endhost device when the endhost device is connected to the first switch device. The first switch device uses the endhost device identification communication to identify an endhost device type of the endhost device and determines, based on the endhost device type, a first switch device role for the first switch device. The first switch device then transmits a first switch device role communication that identifies the first switch device role to a second switch device included in the plurality of switch devices and connected to the first switch device. The second switch device may then determine, based on the first switch device role, a second switch device role for the second switch device.

Abstract: An expander I/O module discovery/management system includes a secondary system chassis housing an expander I/O module coupled to a server device. The server device identifies the secondary system chassis and an expander I/O module port utilized by that server device, and then generates and transmits an expander I/O module reporting communication identifying the secondary system chassis and the expander I/O module port. A primary system chassis houses a switching I/O module coupled to the expander I/O module. The switching I/O module receives the expander I/O module reporting communication and determines that the secondary system chassis identified in the expander I/O module reporting communication is different than the primary system chassis. In response, the switching I/O module assigns a virtual slot to the expander I/O module, and assigns a virtual port associated with the virtual slot to the expander I/O module port identified in the expander I/O module reporting communication.

Abstract: A multi-fabric VLAN configuration system includes a first fabric with server devices that are configured to communicate using VLANs, a primary I/O module coupled to the server devices, and a first fabric management system coupled to the server devices and the primary I/O module. The first fabric management system identifies VLAN information associated with the VLANs, automatically configures the primary I/O module using the VLAN information, and causes the VLAN information to be transmitted by the primary I/O module. A second fabric in the multi-fabric VLAN configuration system includes a leaf switch device that is coupled to the primary I/O module and that receives the VLAN information, and a second fabric management system that is coupled to the leaf switch device and that receives the VLAN information from the leaf switch device, and automatically configures the leaf switch device using the VLAN information.

Abstract: An automated Link Aggregation Group (LAG) configuration system includes a plurality of slave switch devices that are each coupled to an endhost device by at least one respective link. Each of the plurality of slave switch devices receives a Link Aggregation Group (LAG) communication from the endhost device, and forwards endhost device information in that LAG communication to a master switch device. The master switch device receives endhost device information from each of the plurality of slave switch devices and determines that each of the plurality of slave switch devices are coupled to the endhost device. In response, the master switch device sends a LAG instruction to each of the plurality of slave switch devices that causes the at least one respective link that couples each of the plurality of slave switch devices to the endhost device to be configured in a LAG.

Abstract: A port configuration migration system includes a primary I/O module connected to a server device via a secondary I/O module. A fabric manager system maps a virtual interface to a first downlink port on the primary I/O module that is connected to the secondary I/O module, with the virtual interface providing a virtual direct connection to the server device. The fabric manager system then configures the virtual interface with communication configuration information for the server device such that communications received via the first downlink port are transmitted using the virtual interface. The fabric manager system then receives a discovery communication from the server device via a second downlink port on the primary I/O module that is connected to the secondary I/O module, and remaps the virtual interface to the second downlink port such that communications received via the second downlink port are transmitted using the virtual interface.

Abstract: A traditional storage platform performs many basic functions, such as storage partitions allocation (i.e., namespace masking) and many advanced functions, such as deduplication or dynamic storage allocation. These functions need to be managed and this results in a multiple management system paradigm, in which a fabric management application manages the fabric connectivity policies (i.e., Zoning), while a storage management application manages the storage namespace mappings and advanced functions. Embodiments herein provide for centralized management for both connectivity and storage namespace mapping, among other advanced features. Namespace zoning information may comprise Namespace ZoneGroups, Namespace Zones, Namespace Zone Members, Namespace ZoneAlias, and Namespace ZoneAlias Members, which expand the NVMe-oF zoning framework from just connectivity control to full Namespaces allocation.

Abstract: A Centralized Discovery Controller (CDC) uses built-in intelligence to determine or estimate whether a connection with a non-volatile memory express (NVMe) entity has been discontinued intentionally or whether a connection loss is rather transient, e.g., due to a temporary network issue. In the former case, the CDC sends out asynchronous event notifications (AENs) and communicates the absence of the NVMe entity in a get log page to indicate an administrative access control action, e.g., a user intervention due to a zoning change or the removal of an entity due to a hardware failure. In the latter case, the CDC creates an “unreachable” entry in the name server database that indicates a CDC connectivity failure but maintains the entity in the name server database despite the connection loss, refraining from sending out notifications to relevant (or impacted) entities to increase bandwidth, traffic stability, and network availability.

Abstract: Embodiments herein comprise a centralized NVMe-oF namespace masking and configuration repository, which may be referenced for convenience herein as a distributed configuration service (DCS). By centralizing the functionality, there is no longer a requirement that each host, network element, and subsystem have its own user interface (UI). DCS embodiments provide a single UI for a number of features, including but not limited to: (1) viewing the list of Host interfaces that are attached to the network and are registered; (2) viewing the list of Subsystem interfaces that are attached to the IP Network and are registered with the DCS; (3) viewing the storage capacity available behind each subsystem interface; and (4) allowing a user to define the Host to Subsystem interface relationships as well as define how much storage should be allocated to each Host.

Abstract: A current technique to enforce a Zoning configuration is referred to as “Hard Zoning”. Hard Zoning is a technique in which network switches in a fabric inspect packets to ascertain if a packet should be forwarded or discarded, according to the communication between nodes allowed by the Zoning configuration. For the network switches to be able to perform this packet-by-packet filtering, Zoning information needs to be supplied to the network switches. However, current approaches involve sending duplicate data to switches. These approaches are very inefficient and cumbersome. Accordingly, embodiments comprise a Centralized Discovery Controller (CDC) that collects network information, generates, for a switch, its appropriate zoning information, and sends the switch-specific zoning information to that switch.

Abstract: A cable connection information display system includes a cable having a first cable connector, and a first cable connection information display subsystem that is included on the cable adjacent the first cable connector. The first cable connection information display subsystem includes a first display device, and a first connection information receiving subsystem that is coupled to the first cable connector and the first display device. The first connection information receiving subsystem receives first connection information, which identifies at least a first computing device and a first port, via the first cable connector and from the first computing device that includes the first port that is connected to the first cable connector. The first connection information receiving subsystem then provides the first connection information for display on the first display device to identify the first computing device and the first port.
