Abstract
An embodiment includes a virtual machine (VM) memory synchronization process for improved failure tolerance. The process includes writing, by an intelligent memory controller (IMC), current snapshot data to a first series of contiguous memory addresses, where the current snapshot data is received by the IMC from a memory of an active VM via a direct memory access (DMA) transfer operation. The IMC executes concurrent threads associated with respective spans of the contiguous memory addresses, where the concurrent threads control compression processing of respective portions of the current snapshot data resulting in corresponding portions of processed current snapshot data, where the concurrent threads comprise a thread bound to a hardware accelerator that performs the compression processing of a portion of the current snapshot data. The process then transmits the processed current snapshot data to a standby VM as a current synchronization snapshot of the active VM.
