Veeam Backup & Replication • Re: [V13] Software RAID support

This feature was taken out because while both software RAID and XFS separately by itself are rock solid technologies, we found that their combination does not work reliably under heavy load and results in I/O lockups that can only be fixed with reboot. For this reason we will not support this combination in our software appliances, since they will become the base of many pre-built physical appliance offerings soon just like you said. And once such appliances ship to customers, the only way to fix the issue would be to come back to every single one with a hardware RAID card and wipe/rebuild everything, which is a complete catastrophe from both support costs and customer experience perspectives.

Therefore please do plan on installing hardware RAID controller (ideally with BBWC) in all your VSA-based backup appliances.
