  "definition": "FaRM is a research distributed-memory platform that uses RDMA and software transaction protocols to access replicated objects across a cluster.",
  "note": "The NSDI 2014 design checks object-header and cache-line versions after a remote read, retrying inconsistent copies. Its shared address space is an object API, not an NVMe namespace. [farm14]\n\nThe SOSP 2015 protocol uses replicated non-volatile logs; its durability design combines battery-backed DRAM with SSD save on power failure. Network completion is interpreted within that protocol. [farm15]\n\nFaSST offers a contrasting two-sided datagram RPC design; its paper did not implement machine-failure recovery. [fasst16]",
