What should an administrator implement FIRST to address power concerns when installing two servers in a single rack?

• A. Increased PDU capacity
• B. Power backup systems
• C. Dual power sources
• D. Heat management solutions

Answer: (A)

Implementing increased PDU capacity is a fundamental step when addressing power concerns for multiple servers in a single rack. The Power Distribution Unit (PDU) is responsible for distributing electrical power to the servers and other devices within the rack. If you are installing two servers, it’s crucial to ensure that the PDU can handle the combined power consumption of both servers without exceeding its maximum capacity. Increased PDU capacity ensures that there is enough power available to support the needs of both servers effectively. This is particularly important for preventing overloads and potential shutdowns or failure of equipment, which can occur if the PDU is insufficiently rated for the aggregate power load. While the other options, such as power backup systems and dual power sources, do contribute to overall power integrity and redundancy, they are secondary considerations that address concerns after ensuring that sufficient power supply is available. Heat management solutions are also important but are more related to cooling the servers after they have adequate power than addressing the fundamental issue of power supply. Hence, starting with increased PDU capacity lays the essential groundwork for a stable and reliable server environment.
