Memory Mirroring Function
Memory mirroring uses two or four memory boards. The available capacity (logical capacity) of the
memory is the half of that of the physical memory. One memory board is set as primary and the other as
secondary. Data is written to both memories. If a memory error occurs, that memory board is
automatically detached while the other memory board continues to operate. The function is
automatically restored after replacing the failed memory or memory board.

Installation Conditions
