We utilize the Supermicro Ultra product line as our main on-site backup device. A reseller recommended it to us under a managed service contract - but the hardware has been fantastic to work with. The device also has an IPMI interface which works similar to VMWare - so you can manage the device. Our setup has 40TB of storage running in a RAID 6 format. We have 10GB network cards on this device - so backups within the same building run tremendously fast. Branch offices are throttled by the bandwidth at each of those locations. We have been utilizing these Supermicro devices for three years now - deployed just before COVID. Still happy with their performance and functionality.
