Supercapacitor-Based Power Backup Prevents Data Loss in RAID Systems
Supercapacitor-Based Power Backup Prevents Data Loss in RAID Systems
02.20.2018 · Circuits
Redundant arrays of independent disks, or RAID, systems, by nature are designed to preserve data in the face of adverse circumstances. One example is power failure, thereby threatening data that is temporarily stored in volatile memory. To protect this data, many systems incorporate a battery-based power backup that supplies short-term power – enough watt-seconds for the RAID controller to write volatile data to nonvolatile memory...
