Abstract: Techniques for container environment management are disclosed. For example, a method manages, via a virtual container storage interface controller, a generic mapping for one or more container storage attributes for a set of storage specific container storage interface drivers respectively associated with a set of storage arrays of a storage system so as to isolate an application program, executing on a host device accessing one or more storage volumes stored on the set of storage arrays, from the set of storage specific container storage interface drivers. For example, the isolation can provide a layer of abstraction for application specific handles from the actual underlying storage and then enable use of the abstraction to provide services such as, but not limited to, seamless data mobility.

Abstract: Techniques for application copy management in container environments are disclosed. For example, a method obtains a copy of an application program, wherein the copy of the application program is a copy generated for a first cluster of a container-based information processing system within which the application program is deployed. The method then utilizes the copy of the application program from the first cluster to deploy the application program in a second cluster of the container-based information processing system.

Abstract: Techniques for managing node failures in container environments are disclosed. In one example, a method determines when a first node executing at least one containerized workload has failed. In response to determining the first node has failed, the method marks a configuration object for the first node with an indicator that the first node is not to be used to schedule execution of a subsequent containerized workload, isolates from the first node one or more storage volumes used by the first node, and deletes configuration objects for the one or more storage volumes and for the containerized workload. The method then causes creation of a replacement containerized workload for execution on a second node, removes one or more artifacts associated with the containerized workload from the first node, and removes the indicator from the configuration object for the first node.

Abstract: Techniques for obfuscating and/or de-obfuscating data using bit-level shard masks are disclosed. Shard masks are generated. The shard masks are designed to shard a block of data into a number of shards for distribution and storage among a number of storage arrays. The shard masks shard the block of data at a bit-level granularity. The shard masks are applied to the block of data to generate the shards. The shards are then distributed among the storage arrays for storage on the storage arrays.

Abstract: In highly-available Open Shortest Path First (OSPF) routing in a network, the dynamic state of a backup OSPF instance in a router is synchronized with the dynamic state of an active OSPF instance using explicit message transmission from the active instance to the backup instance. After this, the dynamic state synchronization of the backup OSPF instance is maintained using a combination of explicit message updates from the active OSPF instance together with a message flow-through mechanism. In the event of fail-over of the active OSPF instance, then the router recovers seamlessly without reconfiguring or interrupting traffic among peer routers in the network, by functionally substituting the synchronized backup OSPF instance for the active OSPF instance, such that the backup OSPF instance establishes itself as the new active OSPF instance.

Abstract: If an active router Master Control Processor (MCP) fails, a backup MCP switches over without interrupting peer network router connections, because all previously established connection parameters are replicated on both MCPs. Once the MCP programs line cards, the packet forwarding modules and embedded system function without further involvement of the MCP until the next programming update. Messages flow through the backup MCP and then through the active MCP, which outputs messages through the backup MCP. Thus the backup MCP captures state changes before and after the active MCP. Both MCPs maintain replicated queues in which they store replicated messages awaiting processing or retransmission. If acknowledgment of receiving a transmitted message is received from a destination peer router, that message is deleted from both MCPs. If acknowledgment is not received within a predetermined interval, the stored message is retransmitted.
