Project Description
Network Attached Storage
The BHVR 4 module is a mass storage system. Mass storage systems are also known as “Network Attached Storage”, so called NAS.
Data is saved on configurable RAID Arrays (Redundant Array of Independent Disks). RAID levels 0, 1, 5 and Linear are supported.
- Data backup
- Recording of diagnosis or image data
- File server with redundant data storage
