Abstract: An apparatus comprises a processing device that is configured to identify first and second subsets of nodes in a plurality of nodes, the first subset of nodes having dependencies with a first node in the plurality of nodes and the second subset of nodes having dependencies with a second node in the plurality of nodes. The processing device is configured to select the first node for an upgrade and to determine that the second node is not included in the first subset. The processing device is configured to determine that the first node is not included in the second subset and to upgrade the first and second nodes at least partially in parallel based at least in part on the determination that the second node is not included in the first subset and the determination that the first node is not included in the second subset.

Abstract: A method for defining local failover within a storage system using storage group containers includes creating a plurality set of storage groups from physical storage resources of a storage array of the storage system, and creating a masking view identifying a first subset of the storage groups and specifying that Thin Logical Units (TLUs) in the first subset of storage groups are visible only to a primary Software Defined Network Attached Storage (SDNAS) process executing on the storage system and to a backup SDNAS process executing on the storage system. The first set of storage groups includes a Virtual Data Mover (VDM) configuration/root TLU and all user data TLUs used by the primary SDNAS process to thereby enable the set of storage groups used by the SDNAS to be used as a container for local failover.
