Abstract: A test controller functionally tests components of a modular data center (MDC) that is being manufactured. Functional test(s) for quality assurance of an environmental control system (ECS) are determined for an information technology pre-assembled component (ITPAC) module and an environmental system (ES) module that are configured for being coupled together for cooling of heat-generating equipment of the ITPAC module at a deployed location. For each functional test(s), the test controller identifies input signal value(s) associated with one of the modules. The test controller emulates, via a communication test cable connected between the one module and the test controller, the identified input signal value(s). The test controller determines, via the communication test cable, any response by the one module to the input signal value(s). The test controller compares the determined response to an expected response and generates and outputs test data based on the comparison.

Abstract: Failover between decentralized identity stores in the context of there being multiple decentralized identity stores that are each under the control of a single decentralized identity to store data belonging to or regarding the decentralized identity. Third parties can use the decentralized identity to at least conditionally access the data of the primary decentralized identity store. However, in response to detecting a failover event, one of the remaining decentralized identity stores is promoted as the new primary decentralized identity store. As part of this promotion, the new primary decentralized identity store replaces the old primary decentralized identity store as being the decentralized identity store that is accessed using the decentralized identity.

Abstract: Occurrence of a RAID double failure in a slice of a RAID protection group (failed slice) renders data stored in the back-end tracks of the failed slice vulnerable to loss. When a RAID double failure is detected, a new slice is added to the RAID protection group. Front-end tracks that map to the good back-end tracks of the failed slice are moved from the back-end tracks of the failed slice to the back-end tracks of the newly added slice. Any front-end tracks that mapped to the bad back-end tracks of the failed slice are made to be write pending and written to corresponding back-end tracks of the newly added slice. Front-end tracks that map to the bad back-end tracks may be made to be write-pending in connection with a host write operation, by reading the front-end tracks from a local backup, or from a remote backup location.
