Hi All,

During VM migration from one physical server to another physical server, is there any possibility to read/write by both physical servers to common lun during high read/write operation . Is ESX/ESXi has clustering software??

Only one server at a time is handling storage I/O for a virtual machine.  During a vMotion migration, once all of the memory contents have been transferred to the destination host, the source host releases the disk lock and relinquishes ownership of the virtual machine.  The destination host then locks the virtual machine's disk files and resumes I/O.
