It is intended to be durable and available despite host crashes and localized hardware failures. They discuss getting 64GB back into DRAM in 0.6seconds from secondary backup store. The trick is to have many hosts share the burden, so that when one host goes down, 1/100 of its memory is quickly sucked into each of 100 machines from another 100 disk/flash backups. Neat.
