Live Memory Recovery Using a Pluggable Memory Module

A method for live dynamic random-access memory recovery comprising:

• detecting that a spare memory module has been inserted into a computing device based on a signal transmitted from the spare memory module;
• initializing the spare memory module;
• identifying a dynamic random-access memory (DRAM) module of the computing device that is predicted to fail;
• transmitting freeze instructions to a virtual machine manager to pause virtual machines executing on the computing device;
• transferring memory data from the DRAM module to the spare memory module;
• remapping memory addresses from the DRAM module to the spare memory module;
• and
• transmitting unfreeze instructions to the virtual machine manager to resume the virtual machines executing on the computing device.

At least one non-transitory machine-readable medium comprising instructions for live dynamic random-access memory recovery that, when executed by at least one processor, cause the at least one processor to perform operations to:

• detect that a spare memory module has been inserted into a computing device based on a signal transmitted from the spare memory module;
• initialize the spare memory module;
• identify a dynamic random-access memory (DRAM) module of the computing device that is predicted to fail;
• transmit freeze instructions to a virtual machine manager to pause virtual machines executing on the computing device;
• transfer memory data from the DRAM module to the spare memory module;
• remap memory addresses from the DRAM module to the spare memory module;
• and
• transmit unfreeze instructions to the virtual machine manager to resume the virtual machines executing on the computing device.
