Abstract: Template based automatic recovery of virtual machine guest operating systems is provided, that is configured to execute recovery operations within a virtual machine in response to generation of dial-home messages. The error recovery operations, in some embodiments, are based on error recovery templates that specify dial-home event specific sequences of diagnostic operations and actions to be taken to attempt to recover from the errors that cause the dial-home events. By enabling the virtual machine to internally recover automatically from at least a subset of dial-home errors, it is possible to greatly reduce the support cost associated with providing support services for maintaining operation of storage systems. Additionally, enabling automatic recovery of particular errors can reduce the amount of time the storage system or particular aspects of the storage system are inoperable, thus increasing the reliability of the storage system.

Abstract: In accordance with one or more embodiments of the invention, a method is provided for re-tiering files and folders located in a cloud-based file system without crawling all the files and folders in the cloud-based file system. The method utilizes the meta-data for the files and folders to determine, based upon provided rules, which tier a file or folder should be assigned to. By utilizing the meta-data, the use of expensive cloud resources may be minimized when there is a need for re-tiering the files and folders into appropriate cloud tiers.

Abstract: The meta data containing count and key fields of CKD records are reversibly decoupled from the user data of the data field so that the data can be deduplicated. Multiple CKD records may be coalesced into a larger size CKD track. The coalesced meta data is compressed and stored in a CKD hash table. The user data is hashed, and the hash is used as a hash key that is associated with the compressed meta data in the CKD hash table. When the hash of user data associated with a CKD write IO matches the hash key of an existing entry in the table, data duplication is indicated. The compressed meta data is added to the entry and the user data is deduplicated by creating storage system meta data that points to the pre-existing copy of the user data. The storage system metadata includes unique information that enables the corresponding compressed metadata to be subsequently located in the hash table to reassemble the CKD records.

Abstract: A testing method accesses tracing data comprising a plurality of tracing records corresponding to a plurality of test cases executed on a target system. The target system includes a plurality of microservices configured in accordance with a REST API. A dynamic test analyzer accesses the tracing data and imports a definition of the REST API. The analyzer checks each tracing record for consistency with the API definition. Based on this checking of the tracing records, one or more coverage metrics may be calculated. If any one or more of the one or more coverage metrics fails to exceed a threshold coverage, a testing action may be required. In some cases, the testing action may be selected from either seeking additional coverage of the APIs included in the target system or seeking additional test result coverage.

Abstract: A method and system for predicting post-upgrade outcomes in information technology environments through proactive upgrade issue testing. At least with respect to computing, an upgrade may entail the replacement of a product—in the form of hardware, software, and/or firmware—with a newer or better version, which may serve to bring the product up to date, improve the characteristic(s) of the product, and/or resolve any issue(s) inflicting the product. Further, the process of upgrading a product in view of an issue therein is often reactive—that is, it is often required that a customer experiences and reports an issue for a product to a vendor prior to the issuance of an upgrade to the customer that addresses the issue for the product by the vendor. Presently, what is lacking is a mechanism through which product upgrades may be presented to customers proactively in order to minimize product failure and/or downtime.

Abstract: A drive subsystem engages in data communication with a storage controller by establishing first and second communication ports, wherein the second port is configured for decryption and forwarding of decrypted communications to the first port. The drive subsystem receives and processes data communications having selective encryption and identification of target port, by (1) for a security command containing secret data (e.g. a passphrase) enabling operation of a target drive, receiving the security command at the second port, decrypting the security command and forwarding it to the first port for delivery to the target drive, and (2) for data commands by which the storage controller stores and retrieves data to/from the target drive, receiving the data commands in non-encrypted form at the first port directly from the storage controller for delivery to the target drive.

Such techniques further involve performing concurrent reconstruction on the group of storage units.

Abstract: A variable holder module secures a variety of different expansion cards that may be installed within a computer or other information handling system. The holder module has a multi-sided component that is orientable according to which expansion card is to be secured within the computer. Each side of the component may thus correspond to a different one of the expansion cards. Once the expansion card is determined, a human or robotic picker need only orient component to the side that corresponds to the make/model of the expansion card. The holder module is thus adaptable to secure many different expansion cards that may be installed within the computer.

Based on the workload information and the engagement and dependency predictions, the computing device may determine workload priority predictions for the plurality of workloads. The computing device may assign, based on the resource predictions and workload priority predictions, network resources of the network to the plurality of workloads.

Abstract: The cause of a failure to satisfy a high priority service level objective of a storage object or storage group is localized within a storage array. Storage objects that have been assigned low priority service level objectives are analyzed to determine whether their performance paths overlap with the performance path of the high priority service level objective storage object or storage group at the location of the cause of the failure. The low priority service level objective storage objects having performance paths that overlap with the performance path of the high priority service level objective storage object or storage group at the location of the cause of the failure are targeted for IO data rate reduction in order to free resources to restore compliance with the high priority service level objective. The other low priority service level objective storage objects are not targeted.

Abstract: Systems and methods for enforcing media access control (MAC) learning limits (MLLs) on multi-homed access ports comprise configuring MLL violation actions to be performed by a virtual extensible local area network (VxLAN) tunnel endpoint (VTEP). The VTEP is multi-homed to VTEPs and comprises an Ethernet segment (ES) access port. A BGP EVPN or similar protocol may be used to communicate MLL information across VTEPs participating in the multi-homed ES to keep MACs and MLL violation actions consistent. The violation actions may comprise initiating a shutdown message to shut down an ES. Once an MLL violation associated with a MAC that has been received at the VTEP is detected, the VTEP may enforce the MLL by performing one or more of the configured MLL violation actions and propagate the same to other VTEPs.
