hardware module.
Even if one hardware module stops, the server can continue operation with the other module. After the
failed module is replaced, the new module will obtain information from the other and resume operation.
NEC Express5800/ft series is a highly fault-tolerant server that achieves continuous computing
operations, data storage mirror, and continuous network connection. It allows you to run
Windows Server-based applications.
NEC Express5800/ft series achieves continuous computing operations for the Windows server
and server-based applications with its redundant CPU processing and redundant memory. It
assures data redundancy through duplication of server data on an independent storage system.
These features eliminate server downtime that is usually caused by network disconnection or
trouble with the I/O controller, Ethernet adapter or disk drive, and support operation of the
network and server applications continuously. While being transparent to application software,
NEC Express5800/ft series achieves high fault-tolerance.
