3. Standard FeaturesChapter 1 General Description3.2 Fault-Tolerant FeaturesHardware modules work while synchronizing and comparing with each other.Even if one hardware modulestops, 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, datastorage mirror, and continuous networkconnection. It allows you torun Windows/VMware Server-basedapplications.Express5800/ft series achieves continuous computing operations for theWindows/VMware server andserver-based applications with its redundant CPU processing and redundant memory.It assures dataredundancy through duplication of server data on an independent storage system. These features eliminateserver downtime that is usually caused by network disconnection or trouble with the I/O controller, networkadapter 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 analarm 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-basedmanagement tool, allows you to monitor, view, and configure Express5800/ft series. This tool also supports bothlocal 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.After the failed module is replaced, the new module obtains information from the other and resume operation.Express5800/R320c-E4, R320c-M4, R320d-E4, R320d-M4 User's Guide42
