Fault-Tolerant Features
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.
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/VMware Server-based
applications.
Express5800/ft series achieves continuous computing operations for the Windows/VMware 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, network
adapter or disk drive, and support operation of the network and server applications continuously.
Express5800/ft series detects status changes, errors, the Windows/VMware Log of these events. If you use an
alarm notification tool, you can configure 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 Express5800/ft series. This tool also supports both
local and remote management of Express5800/ft series.
Major components are duplexed:
Even if one hardware module stops, the server can continue operation with the other module.
