Intelligent rolling upgrade for data storage systems

A system for facilitating upgrades in a computing storage environment, comprising:

• a processor in communication with a memory device, the processor operational on a management node in the computing storage environment, wherein the processor is adapted for:
• selecting one of an available plurality of rolling upgrade policies registering at least one selectable upgrade parameter for an upgrade window,
• setting a node down tolerance factor for at least one node in the computing storage environment,
• determining if a number of at least one of a plurality of nodes in the computing storage environment currently down, including a target node to be upgraded, does not exceed the node down tolerance factor, and
• if the node down tolerance factor has not been exceeded, checking a cluster health.

A computer program product for facilitating upgrades in a computing storage environment by a processor in communication with a memory device, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

• an executable portion for selecting one of an available plurality of rolling upgrade policies registering at least one selectable upgrade parameter for an upgrade window;
• an executable portion for setting a node down tolerance factor for at least one node in the computing storage environment;
• an executable portion for determining if a number of at least one of a plurality of nodes in the computing storage environment currently down, including a target node to be upgraded, does not exceed the node down tolerance factor;
• and
• an executable portion for, if the node down tolerance factor has not been exceeded, checking a cluster health.
