Abstract
The disclosure provides a system, method, and computer readable medium for booting a diskless client in an information handling system (IHS). Cached boot data is stored in a non-volatile memory of the diskless client. The diskless client sends a boot request with an identifier and receives a boot reply containing an image signature associated with the identifier. The diskless client determines whether there is a match between a cached image signature and the received image signature. If there is a match, the diskless client boots with the cached boot data. If there is not a match, the cached boot data is invalidated and new boot data is requested and received from a server. The diskless client stores the new boot data in the non-volatile memory and boots with the new boot data. The cached boot data may be update when network traffic is below a predetermined level and/or an administrator change to boot data affects a plurality of diskless clients. The diskless client request and receives updated boot data stores the updated boot data in the non-volatile memory.
