Fail-Safe Software

Express5800/320Ma System Software works in conjunction with lockstep technology
to prevent many software errors. Fail-safe software features capture issues and report
them to NEC Technical Support or your authorized service representative. Even data
in memory can be constantly protected and maintained.
NEC Solutions (America), Inc. also provides drivers that increase the fault tolerance
and manageability of third-party drivers for other adapters in the system.
Services
NEC Solutions (America), Inc. provides software fault-tolerant services that run on your
system as Windows-based services. These services constantly monitor for, and
respond to, hardware problems. Applications do not need customization to support the
services.
These services start automatically when the system boots and remain running during
normal operation. If a situation requires system administrator intervention, you can use
Computer Management to manually start and stop system services. See
