Hosting virtual machines on a secondary storage system

A system comprising:

• a processor configured to:
• host at least a portion of a virtual machine on at least one node of a first subset of a plurality of nodes of a secondary storage system, wherein the secondary storage system stores data associated with one or more primary storages, and the virtual machine comprises a plurality of portions that are distributed between the plurality of nodes of the secondary storage system and the virtual machine is configured into a first state of a plurality of states, and wherein, in the first state of the plurality of states, the plurality of portions of the virtual machine are distributed between the first subset of the plurality of nodes of the secondary storage system and each of the plurality of nodes of the secondary storage system included in the first subset of the plurality of nodes of the secondary storage system is configured to store a portion of the virtual machine in a corresponding storage device of the corresponding node;
• select based on at least one of storage, memory, and processing resources of one or more nodes of a second subset of the plurality of nodes of the secondary storage system, a node from the second subset of the plurality of nodes of the secondary storage system to host the virtual machine in a second state of the plurality of states, wherein, in the second state of the plurality of states, the plurality of portions of the virtual machine are distributed between more than one node among the second subset of the plurality of nodes of the secondary storage system;
• move to nodes of the second subset of the plurality of nodes of the secondary storage system the plurality of portions of the virtual machine hosted on the first subset of the plurality of nodes of the secondary storage system, wherein the selected node is included in the nodes of the second subset of the plurality of nodes of the secondary storage system and is configured to host at least one portion of the plurality of portions of the virtual machine;
• and
• run the virtual machine in the second state of the plurality of states on the selected node;
• and
• a memory coupled to the processor and configured to provide the processor with instructions.

A computer program product, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions to:

• host at least a portion of a virtual machine on at least one node of a first subset of a plurality of nodes of a secondary storage system, wherein the secondary storage system stores data associated with one or more primary storages, and the virtual machine comprises a plurality of portions that are distributed between the plurality of nodes of the secondary storage system and the virtual machine is configured into a first state of a plurality of states, and wherein, in the first state of the plurality of states, the plurality of portions of the virtual machine are distributed between the first subset of the plurality of nodes of the secondary storage system and each of the plurality of nodes of the secondary storage system included in the first subset of the plurality of nodes of the secondary storage system is configured to store a portion of the virtual machine in a corresponding storage device of the corresponding node;
• select based on at least one of storage, memory, and processing resources of one or more nodes of a second subset of the plurality of nodes of the secondary storage system, a node from the second subset of the plurality of nodes of the secondary storage system to host the virtual machine in a second state of the plurality of states, wherein, in the second state of the plurality of states, the plurality of portions of the virtual machine are distributed between more than one node among the second subset of the plurality of nodes of the secondary storage system;
• move to nodes of the second subset of the plurality of nodes of the secondary storage system the plurality of portions of the virtual machine hosted on the first subset of the plurality of nodes of the secondary storage system, wherein the selected node is included in the nodes of the second subset of the plurality of nodes of the secondary storage system and is configured to host at least one portion of the plurality of portions of the virtual machine;
• and
• run the virtual machine in the second state of the plurality of states on the selected node.
