A deployment engineer is installing eight PowerEdge XE9680 servers. Two servers will be installed in each of four racks. The data center managers must plan for the power needed to supply power to
the four racks.
What power consumption information can the deployment engineer give the data center manager?
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:
Total Power Requirement: With two servers per rack, each rack will have a total ofeight 2800-Watt PSUs. This information helps in calculating the total power draw for each rack.
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.
A deployment engineer is discussing the benefits of the PowerEdge XE9680 to a data center manager. A customer has many PowerEdge servers. They require the greatest amount of network
throughput possible. The manager asks how many PCle risers and network PCI cards the server can support.
What should be the response?
The PowerEdge XE9680 server supports a high level of network throughput, which is achieved through its PCIe risers and network PCI card capacity. Here's the detailed information:
Riser Cards: Riser cards are used in servers to extend the PCIe slots and make them more accessible for installing additional cards, such as network cards.
Network Card Support: Each riser can support multiple PCIe network cards, allowing for expansion and increased network throughput.
By utilizing the full capacity of PCIe slots with the appropriate risers and network cards, the PowerEdge XE9680 can meet the customer's requirement for the highest network throughput possible.
A customer wants to implement 20 PowerEdge XE9680 servers for development and rendering of their studio CGI production. The solution includes a shared development environment with multiple
outside partners, professionals, and hobbyists.
Due to the heating and cooling limitations of the data center, what GPUs should be used for the servers?
For a customer implementing PowerEdge XE9680 servers in a data center with heating and cooling limitations, the NVIDIA A100 GPUs are a suitable choice. Here's a detailed explanation:
By choosing NVIDIA A100 GPUs, the customer can ensure that their PowerEdge XE9680 servers will deliver the required performance for CGI production while adhering to the data center's heating and cooling limitations.
A deployment engineer is installing a PowerEdge XE8640 server. The server is on a lift, and they have aligned the server inner rails with the rail assemble that are secured in the rack. The engineer
can only push the server into the rack a short distance before it stops. Pushing forcefully causes the rack to slide back.
What action should the deployment engineer take?
Understanding Rail Locks:
The PowerEdge XE8640 server rails are equipped with a locking mechanism to secure the server during transport and installation. This prevents the server from moving unintentionally and ensures stability.
Identifying the Issue:
When the server stops after being pushed only a short distance into the rack, it is likely due to the rail lock engaging. This lock must be released to allow the server to slide fully into place.
Releasing the Rail Lock:
Locate the rail lock mechanism on the rails. This is typically a lever or button that, when pressed, releases the lock, allowing the server to slide further into the rack.
Detailed Steps:
Align the Server: Ensure that the server is properly aligned with the rails before proceeding. Misalignment can cause the server to get stuck or make it difficult to release the lock.
Press the Release Mechanism: With the server partially inserted, locate and press the release mechanism on both sides of the rails. This should disengage the locks.
Slide the Server: Once the locks are released, carefully push the server into the rack until it is fully seated. Ensure that the server is evenly aligned to avoid binding or getting stuck.
Avoiding Forceful Methods:
Avoid using excessive force to push the server into the rack as it can cause damage to the server, rails, or rack. Additionally, pushing forcefully without releasing the rail lock can lead to misalignment and potential hardware issues.
Safety and Assistance:
Ensure the lift is stable and properly aligned with the rack to prevent movement. If needed, have an assistant stabilize the lift while performing the installation steps.
Reference to Official Documentation:
Refer to the Dell EMC PowerEdge XE8640 Installation and Service Manual for specific instructions and diagrams illustrating the rail lock mechanism and proper installation procedures.
Dell EMC PowerEdge XE8640 Installation and Service Manual: This manual provides detailed guidelines on the proper use of rail kits and the mechanism for releasing rail locks during server installation.
Dell EMC Technical Specifications Guide: Offers comprehensive details on the hardware specifications and installation processes for Dell PowerEdge servers, including rail systems and locking mechanisms.
A deployment engineer is connecting the network cables on an XE9680 server. The data center administrator wants to know why the server does not have an OCP card for network connectivity.
How should the engineer respond to the administrator's query?
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.
