IT teams that need more storage without replacing a working array use PowerVault Expansion Enclosures to extend existing ME systems with added capacity and the same management model. ME412 suits compact growth, ME424 adds denser room for shared data, and ME484 gives higher-capacity expansion when rack space is tight.
They fit data centres and similar environments that need extra room for backups, archives, project files and secondary workloads, while keeping control on the current platform. Mixed drive support and redundant power help maintain continuity as storage grows, with a straightforward path to more capacity and less disruption.
