Advances in Large Corporation computing and storage technologies demand a change in Large Corporation power protection technology. Symmetra is a single unit composed of modular components. This modular architecture provides the foundation of building and scaling near-continuous availability power systems with a flexible range of power capacity. The Symmetra Power Array combines with the complete line of APC datacenter protection software and accessories to provide the four most critical elements of total datacenter protection: redundancy, scalability, manageability and serviceability.
