Automatic rule based grouping of compute nodes for a globally optimal cluster

A system comprising:

• a cluster, wherein the cluster comprises one or more sites and each site comprises one or more compute nodes;
• a local storage communicatively coupled to the clusters via local area networks;
• and
• a virtual infrastructure management (VIM) server coupled to the clusters via a wide area network (WAN) is to:
• obtain a list of operating, provisioned and/or about to be provisioned compute nodes in a cluster;
• obtain user configured and run-time network parameters of a network interface card (NIC) of each compute node in the list;
• measure round-trip times (RTTs), using a ping, between each compute node and each of remaining compute nodes in the list;
• group the compute nodes in the list based on the obtained user configured and run-time network parameters and/or the measured RTTs;
• and
• perform a high availability (HA) operation in the cluster using the grouped compute nodes.

A non-transitory machine-readable storage medium encoded with instructions that, when executed by a processor, cause the processor to:

• obtain a list of operating, provisioned and/or about to be provisioned compute nodes in a cluster;
• obtain user configured and run-time network parameters of a network interface card (NIC) of each compute node in the list;
• measure round-trip times (RTTs), using a ping, between each compute node and each of remaining compute nodes in the list;
• group the compute nodes in the list based on the obtained user configured and run-time network parameters and/or the measured RTTs;
• and
• perform a high availability (HA) operation in the cluster using the grouped compute nodes.
