How long will the update process take to complete? Will there be any interruptions in service during the update process?
The update process varies depending on the NAS model, number of drives, and any running storage services. Single-controller models, such as the TES-x85u series, might finish an update in as quickly as 20 minutes, while dual-controller models, such as the Enterprise ZFS NAS Series, might take up to 45 minutes.
Dual-controller models support rolling updates; while one of controller is updating, the other controller takes over in order to avoid any interruption of service. Unfortunately, single-controller models will experience a temporary interruption of service during the update process.
Dual-controller models take longer to update, but don't experience service interruptions during the update.
