A Storage Administrator has an existing single appliance Dell EMC PowerStore 3000T cluster. An additional PowerStore 9000T has been purchased to add…

The Dell PowerStore architecture is designed for flexible scale-out capabilities. A single PowerStore cluster can contain up to four appliances. A key feature of this design is the ability to mix different PowerStore T models within the same cluster. Therefore, adding a new PowerStore 9000T appliance to an existing cluster that contains a PowerStore 3000T is a fully supported operation. The administrator should follow the standard "Add Appliance" procedure within PowerStore Manager, ensuring network connectivity and software version compatibility are met.

B. The Top-of-Rack (ToR) switching infrastructure should be configured for multi-appliance support from the initial setup; adding a new appliance does not require reconfiguring core inter-switch links like VLT.

C. This statement is incorrect. PowerStore T model appliances can be mixed within the same cluster. The only restriction is that PowerStore T and PowerStore X models cannot be mixed.

D. PowerStore clusters do not require identical hardware configurations across appliances. The system is designed to manage resources across heterogeneous models with different specifications, such as varying numbers of NVRAM drives.

Section 2.1

"Cluster Composition": "A PowerStore cluster can be comprised of up to four appliances of any PowerStore T model type. Any combination of PowerStore T models can be mixed within the same cluster... All appliances in the cluster must be running the same version of PowerStoreOS." This directly supports answer A and refutes answer C.

Section 3.2

"Scale-out": "PowerStore is a scale-out platform which allows the user to expand the resources in the cluster by adding more appliances... The user can add any PowerStore T model appliance to an existing cluster of PowerStore T appliances." This confirms the validity of mixing models as described in answer A.

3. Dell PowerStore: Networking Guide for PowerStore T Models (April 2023).

Section: "Multi-appliance cluster cabling" and "Add an appliance": The guide details the network topology required for a multi-appliance cluster. The procedure for adding an appliance involves connecting it to the existing

pre-configured network fabric. It does not mandate re-architecting the inter-switch links (VLT/MCLAG) for each new appliance

which makes option B incorrect.
