Abstract:

A technique implements an administrative user interface of a backend service used to manage and administer on-premises resources, such as storage nodes of a cluster, within a private customer network. The backend service includes a browser configured to issue cross-origin resource sharing (CORS) requests among target storage nodes and a publicly-hosted web application on remote computing systems accessed via a public computer network (i.e., internet) that can be loaded on the browser within the customer network to manage and administer the on-prem resources on the private network. The technique involves the use of CORS over HyperText Transfer Protocol to access an origin that is not reachable via the public internet from a predetermined location of the browser, e.g., within the same customer network as the target storage nodes, particularly to facilitate management of the nodes.

Abstract:

An optimistic and failsafe technique validates network configurations of storage and compute nodes deployed as a cluster. An optimistic aspect of the technique, saves an initial network configuration state of each node as a “failsafe” state and an expected network end-stale is applied to each node. According to a validation aspect of the technique, each node employs a test to validate connectivity with other nodes in the cluster. In response to every validating node responding to a coordinating node that the validation test succeeded, an “all-clear” message is sent to all of the nodes instructing each node to maintain the applied expected network end-state. If any node is unreachable due to a configuration validation failure, then a failsafe aspect of the technique is invoked wherein the all-clear message is not sent and the remaining nodes of the cluster automatically “roll-hack” to the initial failsafe network state after a timeout.
