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.
This server is a highly fault-tolerant server that achieves continuous computing operations, data storage mirror,
and continuous network connection. This server is capable of executing applications running on Windows
operating system or a guest operating system supported by VMware ESXi.
This server achieves continuous computing operations for the 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 hard disk drive, and support operation
of the network and server applications continuously.
This server detects status changes, errors and logs of these events. If you use an alarm notification tool, you
can configure this server to notify you when certain events occur.
This server is installed on the system as a server management solution. NEC ESMPRO, a GUI-based
management tool, allows you to monitor, view, and configure the server. This tool also supports both local and
remote management of the server.
Major components are duplexed:
Even if one hardware module stops, the server can continue operation with the other module.
After the failed module is replaced, the new module obtains information from the other and resumes operation.
