EMC D-PEXE-IN-A-00 Dell PowerEdge XE9680 and XE8640 Install Exam Practice Test

Overview of OCP Cards:

Open Compute Project (OCP) cards are network interface cards designed to provide high-speed networking capabilities. They are often used in data center environments to enhance network performance and flexibility.

OCP Card on Dell PowerEdge XE9680:

For the Dell PowerEdge XE9680 server, an OCP card is not a mandatory component. The server can achieve Power-On Self-Test (POST) and function normally without an OCP card.

Optional Component:

The OCP card is considered an optional component for the XE9680 server. This means it can be added based on specific networking needs but is not essential for the server's basic operations.

Networking Alternatives:

The XE9680 server is equipped with various other network interface options. For instance, it has integrated network ports (LAN on Motherboard, or LOM) which provide necessary network connectivity out-of-the-box.

Customization and Upgrades:

The optional nature of the OCP card allows data center administrators to customize their servers based on their network performance requirements. If high-speed or specific networking features are needed, the OCP card can be added accordingly.

Communicating with the Administrator:

The deployment engineer should explain to the data center administrator that while the OCP card is not included by default, it can be added as per the data center's specific networking needs. The server's design supports flexibility in network configurations.

Redundancy and Load Balancing:

PowerEdge XE8640 servers are designed for high availability and reliability. One key aspect of this design is the redundancy provided by the server's Power Supply Units (PSUs). By connecting each PSU to a different power source, you ensure that the server remains operational even if one power source fails.

Power Source Configuration:

In this scenario, the rack has two distinct power sources: one supplying power to the two left PDUs and the other to the two right PDUs. To maximize redundancy, each PSU should be connected to a different power source.

PSU Placement:

PSU 1 in the left PDUs: Connect PSU 1 to one of the PDUs on the left side of the rack. This ensures that PSU 1 is powered by the first power source.

PSU 2 in the right PDUs: Connect PSU 2 to one of the PDUs on the right side of the rack. This ensures that PSU 2 is powered by the second power source.

Ensuring Redundancy:

By placing PSU 1 on the left and PSU 2 on the right, you create a redundant power configuration. If either power source fails, the other PSU can continue to supply power to the server, maintaining its operation.

Steps for Connection:

Step 1: Verify that the rack's PDUs are correctly connected to their respective power sources.

Step 2: Identify the left and right PDUs based on their power source connections.

Step 3: Connect PSU 1 to a PDU on the left side of the rack.

Step 4: Connect PSU 2 to a PDU on the right side of the rack.

Step 5: Confirm that both PSUs are securely connected and receiving power from separate sources.

Safety and Verification:

Ensure that all connections are secure and that the cables are managed to prevent interference with other components or airflow within the rack. Verify that each PSU is functioning correctly by checking the server's power status indicators.

The PowerEdge XE9680 server is equipped with power supply units (PSUs) that are essential for its operation. Here’s the power consumption information that the deployment engineer can provide:

PSU Specifications: Each PowerEdge XE9680 server comes with four 2800-Watt, 15.6 Amp PSUs1. This specification is crucial for the data center manager to understand the power requirements for each server.

Total Power Requirement: With two servers per rack, each rack will have a total of eight 2800-Watt PSUs. This information helps in calculating the total power draw for each rack.

Power Distribution Units (PDUs): While the number of PDUs required for high availability can vary, it’s important to note that the server’s PSUs feature a C22 input socket1. The data center manager should ensure that the PDUs in the rack are compatible with this type of connection.

Power Planning: The data center manager must plan for the power needed to supply power to the four racks, considering the power draw of the servers and any additional equipment that will be installed.

By providing this detailed power consumption information, the deployment engineer assists the data center manager in planning for the appropriate power infrastructure to support the PowerEdge XE9680 servers.

Server Dimensions and Rack Compatibility:

The Dell PowerEdge XE9680 is a large server with specific dimensional requirements. Ensuring that the customer’s rack can accommodate the physical length and depth of the server is crucial for a successful installation.

Rack Depth and Space Requirements:

Measure the depth of the customer’s rack to ensure it is sufficient to house the XE9680 servers. The server’s dimensions, including its length, should be verified against the available space in the rack.

Server Length Specification:

The PowerEdge XE9680 has a significant depth, typically around 800mm (31.5 inches). The rack must be deep enough to support the full length of the server, including any cable management and airflow requirements.

Checking Rack Specifications:

Verify that the rack adheres to standard dimensions suitable for hosting enterprise-grade servers. Ensure that the rack has appropriate mounting options, such as square or threaded holes compatible with the server’s rail kit.

Pre-installation Verification:

Before arriving on-site, confirm with the customer that their rack meets the necessary specifications. This includes checking for sufficient clearance at the rear for cable connections and at the front for proper airflow.

Importance of Proper Fit:

A rack that cannot accommodate the length of the servers will result in installation failure, potential damage to the hardware, and inefficient cooling. It may also pose safety risks during and after installation.
