However, a complete switch is not always economically viable – even though it offers undeniable advantages. As the Air-Gap-compatible Silent Brick Air (for the Controller G5200) is now only available in limited quantities, the question arises: **How can I still use Air Gap on the G5200 controller?** The answer: the **Silent Brick Max Air**. It offers up to 240 TB (gross) of capacity per medium. Instead of having to handle numerous physical media manually, the air-gap functionality of the Silent Brick Max Air can be semi- or fully automated: - On the Silent Brick Max Air, "Eject" refers to the galvanic (electrical) disconnection of the hard drives from the system. - As was previously the case with the Silent Brick Air, the Eject function can be automated, for example, upon completion of a backup job. - Reactivation can be performed manually by pressing the button on the device. - From the next software version (autumn 2026), time-controlled reactivation will also be supported. The integrated, tamper-proof real-time clock automatically lifts the disconnection after the pre-set period. This allows rotation scenarios to be implemented fully automatically without having to forego a true air gap. The **Silent Brick Max Air** is fully compatible with your G5200 controller and offers improved, enhanced Air-Gap functionality. We would be happy to discuss your specific situation in detail and work with you to find a suitable solution for continuing to use your Silent Brick system – either with your existing G5200 controller and Silent Brick Max Air, or by switching to the new X controller. ### Air Gap An air gap is the complete physical interruption of all network connections between a backup system and the rest of the IT infrastructure, so that the system has no addressable network interface in its offline state and is therefore unreachable by ransomware and attackers.

No. Firstly, depending on your CARE contract, we guarantee up to 10 years of service and spare parts for your existing system. Secondly, we still have a limited number of Silent Brick Air units in stock for upgrading your system (G-Series). The Silent Brick Max Air replaces the Silent Brick Max without any restrictions and also offers a true air gap. As the availability of the Silent Brick Air is limited, we recommend switching your air gap strategy to the new Silent Brick Max Air, which offers up to 240 TB (gross) per unit and provides a fully automatable air gap. #### Which Silent Bricks offer a genuine air gap? Both versions, Silent Brick Pro and Silent Brick Max Air, offer a true air gap. The Silent Brick Pro can be physically removed and thus safely stored in a safe or a bank safe-deposit box, for example. The Silent Brick Max Air remains stationary in the rack, providing galvanic (electrical) isolation for the storage media, but also offers two air gap modes: - In manual mode, the isolation can only be lifted using the button on the device itself - In timed mode, the isolation can also be lifted automatically after a pre-set time has elapsed, enabling automated rotation scenarios The mode is permanently set on the Silent Brick Max Air and cannot be changed via software. #### Do I need to migrate all my data when switching from the G5200 controller to the X controller? No. Existing Silent Brick Max units can still be used with the Controller X – without the need for data migration. As the Controller X does not have slots for Silent Brick Air, this data must be transferred to Silent Brick Pro or Silent Brick Max (Air).
