Abstract
Data is collected by an active node from passive nodes and arranges and stores the collected data on receiving nodes. A source node extracts the data format, and a remote memory blade identification (ID), a remote memory blade address, and ranges of the RMMA space, and composes and sends metadata to the receiving nodes and receiving racks. The RMMA space is unmapped by the source node thereby removing all entries in page tables that map a linear address to a remote RMMA space. The system memory address (SMA) space that is associated with alternative RMMA space is free.
