Why Choose This Product?

• Higher storage density: Eight SFF positions provide additional drive capacity within the supported DL180 Gen9 chassis configuration.
• Hot-plug architecture: Supports compatible hot-plug SFF storage deployment, improving serviceability for appropriate configurations.
• Clear HPE option identification: The 725572-B21 SKU simplifies sourcing, inventory control, replacement planning, and procurement.
• Storage lifecycle value: Expanding an installed DL180 Gen9 can help extend the useful life of existing infrastructure instead of replacing the complete server.
• Controller-ready architecture: The associated Mini-SAS cabling provides the intended connection between the SFF backplane and compatible SAS/SATA controller.
• 12 Gb/s backplane capability: The associated backplane is specified for transfer performance up to 12 Gb/s, providing suitable connectivity for supported high-speed storage devices. 
• Procurement clarity: The kit is clearly identified as a storage cage/backplane option and does not include a power supply, reducing configuration ambiguity.
