Abstract
An embodiment system and method to provide rack awareness for a virtual machine running on a data center server. The virtual machine sends an address resolution protocol request message to a top-of-rack switch to identify a MAC address of the server physical port. The virtual machine receives a reply containing the MAC address of the top-of-rack switch physical port. The virtual machine sends an ICMP packet to the top-of-rack switch with a pre-selected un-routable IP address using the identified physical port MAC address. The virtual machine then receives a message from the top-of-rack switch providing a top-of-rack IP address. The virtual machine employs the top-of-rack IP address to identify the rack location of the server.
