Abstract: An example methodology includes, by a node of an active-passive high availability (HA) cluster, determining that a container on the node has failed with an error and, responsive to a determination that the error is a new error, creating an error object that represents the error, creating an error object that represents the error and initializing a value of an error_code_value attribute in the error object to an initial_value_to_error_code attribute that indicates an initial value to assign to the error_code_value. The method also includes, by the node, incrementing a failcount attribute that indicates a count of a number of container failures on the node, determining whether to restart or failover the container based on a comparison of the failcount attribute and a failure count threshold, and, responsive to a determination to restart the container, attempting a restart of the container on the node.

Abstract: Systems and methods provide witness sled hardware installed in a chassis and supported during failures using management resources of the chassis. A chassis may include data storage devices and Information Handling Systems (IHSs), each storing data redundantly to the storage devices, such in a vSAN. The witness sled provides witness functions, such as arbitrating discrepancies in the redundantly stored data. The chassis includes a chassis management controller (CMC) that maintains a copy of witness transactions stored by the witness sled based on transaction data transmitted by the witness sled to the CMC via the management signaling pathway. The CMC notifies the IHSs of witness operations supported by the CMC in response to a detected fault in the witness sled and utilizes the copy of witness transactions to process witness transactions from the IHSs while the witness sled is not operational.

Abstract: A system, method, and computer-readable medium for assessing and reducing mental strain of a user when the user operates an information handling system comprising. Sensors of the information handling system's display capture light that is reflected from an eye of the user. The captured light is converted to voltage values over time. The voltage values are correlated to eye movement or blinking. If the eye movement or blinking meets or exceeds a threshold value, corrective action is taken to reduce mental strain of the user.

Abstract: System audits messages, communicated internally in copy management system, about copy management jobs, and learns about relationships between message requests for user actions on copy management jobs and subsequent failures of copy management jobs. System creates snapshot of copy management content displayed by user interface and selected by user as context for user's message, and creates message's link to snapshot. System stores user entries that identify message's intended recipient(s), time of availability, and text. If message requests user action on copy management job, and relationship between unanswered requests for user to perform action on copy management job and subsequent failures of copy management job satisfies relationship threshold, then machine learning system sends message via copy management system's internal communication channel to system-selected administrator, who selects message's hyperlink to snapshot.

A chassis may include data storage devices and Information Handling Systems (IHSs), each configured to store data redundantly to the data storage devices, such as part of a vSAN (Virtual Storage Area Network). The witness sled is configured to provide witness functions, such as to arbitrate discrepancies in the redundantly stored data. The chassis also includes a chassis management controller (CMC) configured to initiate a connection with the witness sled via a management signaling pathway in response to a notification indicating a network fault in a high-speed connection used by the IHSs in communicating with the witness sled.

Abstract: Systems and methods provide failover operations for witness sled hardware installed in a chassis. The chassis may include data storage devices and Information Handling Systems (IHSs), each storing data redundantly to the storage devices, such as in a vSAN. A primary witness sled provides witness functions, such as arbitrating discrepancies in the redundantly stored data. The chassis includes a chassis management controller (CMC) that connects with the primary witness sled via a management signaling pathway and maintains a copy of witness transactions stored by the primary witness sled based on transactions transmitted via the management signaling pathway. The CMC generates an inventory of co-located witness sleds. Upon detecting the primary witness sled is not operational, the CMC selects a failover witness sled from the inventory of co-located witness sleds and migrates witness operations of the primary witness sled to the selected failover witness sled.

Abstract: Embodiments of multi-host link aggregation are described for active-active cluster implementations. In one or more embodiments, a multi-host LAG bond in the cluster is created with a bond MAC address designated for the bond. Afterwards, a virtual IP address may be created for all hosts within the multi-host LAG bond. Compared with existing active-active cluster implementation, the presented multi-host link aggregation embodiments do not require extra entities, e.g., load balancer or DNS, which could be a failure point or performance bottleneck, thus makes the active-active cluster implementations more efficient and robust. With the Multi-Host LACP bond and virtual IP on all hosts, the cluster may have increased bandwidth to the cluster service and utilize computing capacity in a network switch for improved workload distribution.
