Automated load balancing across the distributed system of hybrid storage and compute nodes

A computerized method that performs a method to load balance a distributed storage system, the method comprising:

• detecting a load balancing event in the distributed storage system servicing user input output (IOs), wherein the distributed storage system includes a plurality of virtual nodes distributed across a plurality of physical nodes;
• in response to detecting the load balancing event, determining that a current virtual node is to move from a source physical node to a destination physical node without a disruption to the user IOs, wherein the current virtual node is one of the plurality of virtual nodes and the source and destination physical nodes are in the plurality of physical nodes;
• and
• moving the current virtual node from the source physical node to the destination physical node without disrupting the user IOs, wherein the current virtual node is a virtual node for storing objects, and wherein the current virtual node includes a corresponding minor node that is online in a different location during moving of the current virtual node from the source physical node to the destination physical node without disrupting the user IOs.

A load balancing distributed storage system comprising:

• an interconnection network;
• a plurality of physical nodes interconnected by the interconnection network;
• a plurality of virtual nodes;
• and
• a plurality of storage controllers interconnected by the interconnection network, wherein each of the plurality of storage controllers includes,
• a cluster manager that load balances the load balancing distributed storage system, the cluster manager including,
• an agent that detects a load balancing event in the distributed storage system servicing user input output (IOs), wherein the load balancing distributed storage system includes a plurality of virtual nodes distributed across the plurality of physical nodes;
• a master, coupled to the agent, that, in response to detecting the load balancing event, determines that a current virtual node is to move from a source physical node to a destination physical node without a disruption to the user IOs, wherein the current virtual node is one of the plurality of virtual nodes and the source and destination physical nodes are in the plurality of physical nodes;
• and
• a virtual node manager, coupled to the master, that moves the current virtual node from the source physical node to the destination physical node without disrupting the user IOs, wherein the current virtual node is a virtual node for storing objects, and wherein the current virtual node includes a corresponding minor node that is online in a different location during moving of the current virtual node from the source physical node to the destination physical node without disrupting the user IOs.
