Explanation
Unisphere Central is the recommended software tool for the customer as it allows for the monitoring and reporting of multiple Dell Unity and Dell PowerStore arrays through a single interface. It provides a unified management experience and allows for efficient monitoring and troubleshooting of the storage environment.

Explanation
Deduplication is a feature that reduces storage capacity usage by eliminating duplicate data. PowerStore and Unity both have deduplication function, but one key difference is the size of the deduplication block.
PowerStore uses a smaller block size which allows for a higher level of granularity and more efficient deduplication. On the other hand, Unity uses a larger block size which is less granular, but it is still efficient for large sequential data workloads.

Explanation
Both Dell PowerStore T and Dell PowerStore X support the 10 GbE BaseT optional I/O module card type.
This card provides 10 Gbps Ethernet connectivity and can be used to connect the storage array to a network.
The other options are not supported by both models. 25 GbE and 32 Gb Fibre Channel are generally faster and used for high-performance systems, while 8 Gb Fibre Channel is an older standard, and not supported by Dell PowerStore T and Dell PowerStore X.

Explanation
