Hardware modules work while synchronizing and comparing with each other. Even if one hardware
module stops, the server can continue its operation as the service with the other 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 Linux
Server-based applications.
NEC Express5800/ft series achieves continuous computing operations for the Linux 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.
NEC Express5800/ft series detects status changes, errors and other events and notifies the Log of
these events. If you use an alarm notification tool, you can configure NEC Express5800/ft series to
notify you when certain events occur.
NEC ESMPRO is installed on the system as a server management solution. NEC ESMPRO, a
GUI-based management tool, allows you to monitor, view, and configure NEC Express5800/ft
series. This tool also supports both local and remote management of NEC Express5800/ft series.
