ESX/ESXi hosts use the Network Lock Manager (NLM) protocol, which is a standard protocol used to support the file locking of NFS-mounted files. True or False?
If False, Why?
Fasle. VMware has its own locking protocol. NFS lock are implemented by creating lock files on the NFS server. Lock files are named .lck-<fileid>, where <fileid> is the value of the fileid field. When a lock file is created, an update is periodically sent to the lock file to inform other ESX/ESXi hosts that the lock is still active. The lock file updates generate small (84-byte) WRITE requests to the NFS server.
