  Disks provide a stable storage for data, because their mean time between failures can be several years [13]. Unfortunately, main memories do not have such long times to failure. The mean time between crashes/reboots for a workstation may be from a few weeks to a few months. Thus, some form of redundancy is necessary to provide applications that page to remote memory with high reliability.
