The maximum number of expansion enclosures that a single Dell EMC PowerStore 9000T appliance supports is three. This is consistent with the design and specifications provided by Dell for the PowerStore series, which allows for scalability within the storage environment1.
The expansion enclosures are used to increase the storage capacity of the PowerStore system beyond what is available in the base enclosure. Each expansion enclosure connects to the base appliance and adds additional drive slots for storage expansion.
For detailed information on the configuration and limitations of expansion enclosures for the PowerStore 9000T model, administrators should refer to the official Dell PowerStore Hardware Information Guide and the Dell PowerStore Technical Primer. These documents provide comprehensive guidelines on the physical and logical expansion capabilities of the PowerStore systems23. Adhering to these specifications is crucial to ensure proper system performance and to avoid unsupported configurations.
