Just as we need backup power for our sump pump systems to ensure our basements do not flood during a power outage, data servers need backup power to ensure they do not lose data during any loss of power. From generators to battery packs for an entire data center to individual server backup batteries, there are many ways that servers handle backup. This article will focus on backup solutions that are within the server itself to ensure data is not lost during an outage.
Different options for backup power
The main goal of the backup solution is to ensure there is enough energy available to continue running the system until all of the data that is in volatile memory can be transferred into permanent memory.
There are several solutions that are available to provide backup power for servers and we will discuss three different ones and then look at the performance characteristics of each option as it relates to a data storage application.
