Which of the following is NOT classified as a shared-infrastructure system?

The PowerEdge T30 is a tower server designed for small businesses and home office use, featuring a single system configuration that doesn't support shared resources typically required for a shared-infrastructure environment. Shared-infrastructure systems are characterized by their capability to pool resources and allow multiple workloads or applications to share computing power, storage, and networking, which is inherent in systems like the PowerEdge R740, PowerEdge VRTX, and PowerEdge MX7000. These models are designed for scalability and flexibility, often used in data center environments where resource sharing and management of multiple workloads are essential. In contrast, the PowerEdge T30’s standalone design does not provide this shared-infrastructure capability, making it distinct from the other options listed.
