Systems and methods for reducing keyboard, video, and mouse (KVM) downtime during firmware update or failover events in a chassis with redundant enclosure controllers (ECs)

摘要

Embodiments of systems and methods for reducing Keyboard, Video, and Mouse (KVM) downtime during firmware update or failover events are discussed. In some embodiments, a chassis may include: a plurality of Information Handling Systems (IHSs); a first Enclosure controller (EC); and a second EC coupled to the first EC, where the first and second ECs comprise program instructions stored thereon that, upon execution, cause the chassis to: establish a KVM session with a selected IHS via the first EC; in response to the first EC receiving a firmware update command, update and restart the second EC; notify the first EC, by the second EC, that the update and restart is completed; trigger by a first KVM process in the first EC, a second KVM process in the second EC; and take control, by the second EC, of the KVM session.
