Add capacity where backup pressure is building without changing the protection architecture your team already trusts. The HPE StoreOnce 3620 24 TB Capacity Upgrade is designed for organizations that need more room for backup retention, recovery points, and operational resilience inside an existing StoreOnce environment. For infrastructure teams, capacity upgrades matter most when they preserve consistency. This kit extends the usable backup footprint while keeping the platform aligned with deduplicated backup workflows and appliance-based management. That means less disruption to backup operations and a cleaner path to scaling retention as data volumes rise. The value is not just more storage. It is more protected capacity in a system built for backup efficiency, helping teams maintain recovery readiness without moving to a larger footprint than necessary. For environments where backup windows, retention targets, and restore confidence all matter, this upgrade supports a measured expansion strategy.
