2-4 General Description
NEC Express5800/ft series mainly provides the following advantages:
Highly fault-tolerant processing and I/O subsystems
NEC Express5800/ft series use redundant hardware and software to assure server
operation even if one module suffers trouble with its processor, memory, I/O (including
trouble related to the I/O controller), disk drive, or Ethernet adapter.
Continuous network connection
NEC Express5800/ft series maintains continuous network connection by detecting any
trouble with the network adapter, connection, etc. If trouble occurs, the standby network
connection will take over all network traffic processing and thus securely maintain the
network system connection of NEC Express5800/ft series without losing network traffic
or client connection.
Support of multiple network connections
Since NEC Express5800/ft series can support multiple Ethernet connections, you can add
network redundant control or network traffic control.
Industry standard hardware platform
NEC Express5800/ft series uses IA (Intel Architecture)-based system hardware.
No need to modify applications
You can run Windows 2000-compliant applications on NEC Express5800/ft series. Thus,
unlike other highly fault-tolerant products, special API or scripts are not necessary.
Automatic mirroring
NEC Express5800/ft series automatically maintains data as the current data. (You need
to make a setting with VERITAS Volume Manager.)
Automatic detection and notification of faults
NEC Express5800/ft series detects and sorts out all events such as general status changes
and faults, and notifies Windows 2000 Event Log of these events.
Transparent migration
NEC Express5800/ft series constantly monitors events. If trouble occurs on NEC
Express5800/ft series’ server module, it will transparently use a redundant module of the
failed module. This feature maintains data and user access without losing application
service.
Automatic reconfiguration
When the failed module restarts after the trouble is corrected, NEC Express5800/ft series
will perform reconfiguration automatically, and if necessary, resynchronize the affected
modules. Reconfiguration can include CPU processing (e.g., CPU memory), server's
operating system (and related applications), and system data stored on the hard disks. In
most cases, NEC Express5800/ft series automatically restores redundancy of the server
modules after recovery.
