Described techniques provide addressing schemes that account for address differences between active and inactive memory banks in dual bank memory architectures used in software over the air (SOTA) updates implemented using address swapping between the dual memory banks, including providing address translations where needed to obtain one standard addressing scheme for purposes of SOTA updates. A timing and implementation of authentication and booting techniques may ensure that signature authentication and boot processes use correct memory addresses across the dual memory banks to enable updates of both an application and a bootloader to occur. Swapping techniques are described that enable robust, secure swapping between the banks, and that enable SOTA updates to hardware security manager (HSM) software, while ensuring use of such HSM software in dual bank scenarios.

A technique monitors input / output (I / O) and storage ownership takeover activity patterns to detect degraded performance of a highly available and fault tolerant application executing in a multi-site environment. Multiple instances of the application execute in different containers or pods running on virtual machines (VMs) of a compute layer within a containerized (e.g., Kubernetes) clustering configuration that extends across clusters of the sites. A storage layer of the clusters provides shared storage to the pods running on the VMs across the multiple sites. One of the sites is configured as an active storage site configured to receive and service I / O requests from the compute layer. A single instance of the application is active at a time and configured as a “compute owner” of the shared storage to issue the I / O requests to the shared storage. The compute owner and active storage site may not be co-located on the same site, leading to excessive I / O and storage ownership takeover activity patterns indicative of degraded performance. Upon detecting such patterns, the technique automatically triggers a storage failover to ensure that compute owner and active storage site are co-located at the same site.
