What does UPS redundant mean
N+1, also called parallel redundancy, is a safeguard to
ensure that an uninterruptible power supply (UPS) system is always available.
N+1 stands for the number of UPS modules that are required to handle an
adequate supply of power for essential connected systems, plus one more.
If an enterprise data center uses a single large UPS, and
that single module fails, systems will be disrupted. In configuration ups redundant mean, multiple
small UPS modules and batteries are integrated together. During normal
operations, the load is shared equally across all modules and sharing load with
50 % , which behave as if they were a single large UPS device. If a single
module fails or needs to be taken offline for service, the UPS redundant configuration
system will still be able to provide an adequate supply of power because it's
already been configured with one extra module.
When N+1 is used for redundancy, the UPS modules should be
sized so that the total anticipated load can be carried by three modules. The
benefits of N+1 diminish after that point.
