Abstract: Boot firmware for a computing device can be modularly and dynamically composed to facilitate implementing changes and updates to a computing device's firmware. The firmware image can include a primary module, which is responsible for certain basic initializations, and a module list, which can include a listing of additional modules that are to be executed during the boot procedure. The module list can be used to identify and access the selected modules from a module library, such as via globally unique identifiers (GUIDs). Once acquired, the selected modules can be executed, taking into account required dependency modules (whether included in the selected modules or not) and configuration settings. The module library can be stored entirely locally (e.g., as part of a distributed firmware image), entirely remotely (e.g., accessible via network connection), or a mixture of locally and remotely.

Abstract: A method for updating software in one or more servers in a managed system includes bootstrapping of shared secrets to secure communication, using an object store with publicly accessible URLs as a mailbox system between a patch agent locally at the managed system and a patch management server located remotely. The object store provides for indirect and asynchronous communication, allowing the patch management server to manage the updates, whereas the patch agent executes the updates. The patch management server keeps track of update results, and when an update is unsuccessful it performs and supports a remediation process. Both the patch agent and the patch management server keep full logs of the update results to allow for auditing.

A model-driven server migration service as described herein comprises a plurality of modular migration components including, e.g., a snapshot validation component, a snapshot conversion component, an injection component, etc. The model-driven server migration service enables users to customize server migration workflows using server migration templates containing descriptive configurations for some or all of the provided migration components.

Abstract: In an embodiment, described herein is a system and method for creating a suggested task set to meet a target value. A cloud server, in response to receiving a request specifying a target value, retrieves completed task sets from a database. Each completed task set includes a same set of task categories. The cloud server derives a number of ratios from the retrieved completed task sets, including a composition ratio and a conversion rate for each task category, and an addition ratio for the number of completed task sets. Based on the derived ratios and the specified target value, the cloud server constructs the suggested task set, and displays in real-time the suggested task set together with current values for the task categories. The cloud server alerts users of a discrepancy between a current value and the corresponding suggested value for a task category when the discrepancy reaches a predetermined level.

Abstract: Techniques are provided for managing quality of service (QoS) policies in a virtual storage environment. A data storage system receives a request from a host system to connect to a target virtual volume in a storage array of the data storage system, and determines a protocol endpoint which has an assigned QoS policy which corresponds to a QoS policy of the target virtual volume. The data storage system binds the target virtual volume to the protocol endpoint which is determined to have an assigned QoS policy which corresponds to the QoS policy of the target virtual volume, and sends a unique identifier of the protocol endpoint, which is bound to the target virtual volume, to the host system. The data storage system utilizes the protocol endpoint, which is bound to the target virtual volume, to handle data access requests received from the host system for accessing the target virtual volume.

Abstract: When containers run in a guest operating system of a virtual machine running on the host computer system, the containers communicate with each other via ports of each container and a network. The ports of each container stay constant, but the virtual machine in which they run may change its IP address on the network when it is power-cycled. To avoid losing connection to the ports of the containers, a record table that associates static identifiers, such as MAC addresses, of the virtual machine with the container ports is maintained. The static identifiers of the virtual machines do not change and provide a way of identifying the virtual machine on which the virtual container was running before it was powered off. When the virtual machine is powered on, the linkage between the container port and the network can be re-established using the record table.

Abstract: Systems and techniques are described for virtual machine communication and migration. A described technique includes operating server systems that are configured to run virtual machines and providing a virtual network for Internet Protocol (IP) based communications to the virtual machines. The virtual machines can be assigned network addresses, such as IP addresses, on the virtual network. Providing the virtual network can include using separate IP tunnels to effect delivery of IP packets on the virtual network to the virtual machines, respectively. The technique includes migrating a virtual machine running on a first server system to a second server system. The migrated virtual machine can maintain its assigned IP address. The technique includes updating a tunnel endpoint destination associated with the assigned IP address of the migrated virtual machine. The updated tunnel endpoint destination can be based on a network address associated with the second server system.
