A single Dell EMC PowerStore 9000T appliance supports a maximum of three expansion enclosures. These are 2U, 25-drive enclosures that connect to the base enclosure using 100 Gb/s QSFP SAS backend ports. This scalability allows for significant capacity expansion beyond the initial 2U base appliance, enabling the system to grow with storage demands while maintaining a unified management interface. All PowerStore T models, from the 1000T to the 9000T, share this same maximum limit for expansion enclosures per appliance.

A. 8: This is incorrect. No single PowerStore T appliance supports eight expansion enclosures. This number exceeds the documented hardware limit.

C. 4: This is incorrect. The maximum supported number of expansion enclosures for a single PowerStore T appliance is three.

D. 2: This is incorrect. While an appliance can be configured with two expansion enclosures, this is not the maximum supported limit.
