Abstract
A resource matching technique between a primary site and one or more secondary sites accommodates a configuration update of a virtual machine (VM) in a disaster recovery (DR) environment. The resource matching technique determines whether a proposed resource configuration update or change to a primary VM running at the primary site is permissible on a secondary VM configured for failover operation at a secondary site in the event of failure to the primary VM. The technique continuously monitors the availability of resources at each secondary site and enables negotiation between the primary and secondary sites of the proposed configuration change based on corresponding indications resource availability. The resources may include generic resources (e.g., memory, storage capacity and CPU processing capacity) and specialized resources (e.g., GPU types and/or models).
