Abstract
Technology described herein includes an arrangement whereby a hardware-based solution is implemented to enable mirroring of NVRAM data in a master server directly to NVRAM in a sleeper server. Both the master server and sleeper server implement a like motherboard unit, which is configured to implement the mirroring technology. That is, the roles of master and sleeper may be reversed. The master server includes a hardware module that monitors (but does not affect) NVRAM operations at the master server, and replicates those operations via a high speed communications link, such as a fiber optic link, to the sleeper server. The term “high speed communications link” refers to a link with at least 2.5 gigabit speed, and preferably at least 5 gigabit speed. The sleeper server is configured to, when in sleeper mode, suspend control of its own NVRAM module. Instead, the NVRAM module is controlled by a module that is configured to receive NVRAM operations via the fiber optic link, and apply those operations. In this manner, there is a direct mirroring of all master NVRAM content affected in the master's NVRAM to the sleeper's NVRAM. Using technology described herein, this is affected at an “…
