IronWolf Health:

Keep Your Data In Good Shape

For all around well-being, you need prevention, intervention, and recovery.

IronWolf Health Management provides all these aspects of care for supported IronWolf and IronWolf Pro hard drives. Thanks to IHM, which operates in popular NAS operating systems, you can prevent external disturbances from affecting the NAS or drive health, proactively intervene and backup your data when the system notifies, and available industry leading rescue and recovery services should a catastrophic event occur.

Actively Protecting Your NAS

IronWolf Health Management (IHM) is designed to operate on enabled NAS systems, populated with supported Ironwolf SSD, Ironwolf HDDs, and Ironwolf Pro HDDs. IHM helps to improve the overall system reliability by showing prevention, intervention, and recovery options.

Prevention

Enjoy seamless, superior NAS experience as IronWolf Health monitors your system environment and offers preventative actions to secure your data. It keeps tabs on conditions such as temperature, shock, vibration, intermittent connections and signal integrity.

Intervention

Avoid catastrophic data loss events by allowing IronWolf Health to analyze hundreds of parameters, recommending backup as needed. IHM has adaptive algorithms that monitor critical drive and health parameters related to data transfer, performance, readability, writability and overall reliability.

Recovery

In the event of failure, rely on our Rescue Data Recovery Service (2-year service included with IronWolf Pro). IHM provides you easy access to it through the NAS OS.

Schedule. Review. Track.¹

IHM is integrated within the NAS OS in which it allows you to schedule and review each result of the scan when you want to. The NAS OS will keep a log in which it will help track any trends and keep you well aware of how healthy your drive is based on the results of IHM.
