Why Choose This Product?

• Correct PMEM Power Architecture: 827608-B21 is specifically designed for HPE Scalable Persistent Memory, reducing the risk of selecting a conventional 800W PSU that does not meet the PMEM backup-power requirement.
• Integrated PSU + BBU Solution: Combines an 800W power supply with a 400W battery backup function, simplifying the power architecture for supported PMEM deployments.
• Redundant 2-Pack: HPE specifies two PSU/BBU units in the kit, aligning with the redundancy requirements documented for Scalable PMEM configurations. 
• Procurement Accuracy: The distinct 827608-B21 SKU makes it easier for IT procurement teams to identify the exact PMEM power option instead of purchasing a generic 800W server PSU.
• Data Protection Support: Dedicated backup power supports the operational requirements of HPE Scalable Persistent Memory during power interruptions.
• HPE Platform Integration: Designed as an HPE factory-integrated option for compatible Gen10 PMEM systems, supporting more predictable server configuration and deployment.
• Service Planning: HPE provides battery monitoring and replacement guidance, allowing data-center teams to incorporate battery maintenance into lifecycle planning. 
• Future-Ready PMEM Infrastructure: Provides the specialized power infrastructure required when deploying HPE Scalable Persistent Memory rather than relying on a standard server-power configuration.
