Dual NAS HA

Post by sucette » Mon Nov 30, 2020 11:58 am

We want to build an HA storage but cannot afford to buy a dual-controller NAS. However, we have two rackmount NAS, namely TVS-471U-RP and TS-463U-RP, available. Can we build HA (controller + disk redundancy) simply using these two NAS?

There is no HA feature in QTS so the intelligence for it would have to be in other equipment.
RAID have never ever been a replacement for backups. Without backups on a different system (preferably placed at another site), you will eventually lose data!

A non-RAID configuration (including RAID 0, which isn't really RAID) with a backup on a separate media protects your data far better than any RAID-volume without backup.

All data storage consists of both the primary storage and the backups. It's your money and your data, spend the storage budget wisely or pay with your data!
