Systems and Methods for Managing Distributed Metrics Rollups During Non-Disruptive Upgrade

A computer program product residing on a computer readable storage medium having a plurality of instructions stored thereon which, when executed across one or more processors, causes at least a portion of the one or more processors to perform operations comprising:

• upgrading a plurality of storage appliances in a cluster, wherein the storage appliance cluster includes at least a primary storage appliance and a secondary storage appliance;
• determining that an upgrade to a plurality of storage appliances in a cluster has completed;
• querying distributed data for each storage appliance in the cluster based upon, at least in part, determining that the upgrade to the plurality of storage appliances in the cluster has completed;
• and
• combining data stored in a management database in the primary storage appliance and data stored locally in the secondary storage appliance based upon, at least in part, querying the distributed data for each storage appliance in the cluster.

A computing system including one or more processors and one or more memories configured to perform operations comprising:

• upgrading a plurality of storage appliances in a cluster, wherein the storage appliance cluster includes at least a primary storage appliance and a secondary storage appliance;
• determining that an upgrade to a plurality of storage appliances in a cluster has completed;
• querying distributed data for each storage appliance in the cluster based upon, at least in part, determining that the upgrade to the plurality of storage appliances in the cluster has completed;
• and
• combining data stored in a management database in the primary storage appliance and data stored locally in the secondary storage appliance based upon, at least in part, querying the distributed data for each storage appliance in the cluster.
