Frequently asked

When is the Dell Unity 400 end of life?
Dell's published notice sets End-of-Sale for the Unity 400 at Jul 31, 2020. The published end-of-support date is Jul 31, 2026, after which vendor support ends. Check the milestones on this page and plan the refresh ahead of the support cutoff.
What replaces the Dell Unity 400?
Dell has not named a one-for-one replacement in the notice this page is built from. Uniqcli can recommend and quote the current equivalent for the Unity 400, with TAA country-of-origin screening on request.
Can I still buy or get support for the Unity 400?
New units are no longer sold by Dell after the End-of-Sale date; remaining channel stock and refurbished units are the only sources. Vendor support continues until Jul 31, 2026 under an active support contract. For a fleet still running this hardware, the practical next step is a refresh plan — request a quote and we will price the current replacement.
