Systems and methods for automatic failover in modular chassis systems. In some embodiments, a modular chassis includes a chassis management controller and a plurality of server blades. A first of the plurality of server blades may be configured to detect an internal fault to and to transmit a corresponding alert message to the chassis management controller via a midplane connection. Moreover, the chassis management controller may be configured to initiate a migration procedure to transfer one or more workloads from the first server blade to a second of the plurality of server blades.

Automatic failover in modular chassis systems

A method for managing migration of a virtual machine includes accessing a first information handling system and a second information handling system, accessing a network information handling resource, using one or more switches to virtualize access of the network information handling resource to the first and second information handling systems, accessing a virtual bridge associated with the network information handling resource, accessing a virtual machine configured to access the resources of the first information handling system, and copying the operational state of the virtual machine from the first information handling system to the second information handling system using the first virtual bridge. The first and second information handling systems, share the network information handling resource using the virtualized access and the network information handling resource is configured to bind a driver to one or more ports, indicating availability to a virtualization environment regardless of an actual connection status.

Information handling system network addresses are managed based on the location of the information handling system. For example, a blade information handling system chassis has network addresses stored in persistent memory and associated with each of plural slots. A blade information handling system inserted in a slot receives network addresses associated with the slot from a chassis management controller. A baseboard management controller of the blade information handling system receives the network addresses and applies the network addresses to power up networking components to communicate over a network with the network addresses, such as MAC addresses or WWN addresses.
