QUESTION: 25

A platform engineer must install several Dell PowerScale clusters.
Which rack should they use for the A3000 nodes?

Titan-HD
Titan-D
Titan-P

Answer(s): A

Explanation:

For installing Dell PowerScale A3000 nodes, the appropriate rack to use is the Titan-HD (High Density) rack. The Titan-HD rack is specifically designed to accommodate high-density nodes like the A3000, which are part of Dell's archive storage solutions.

Understanding the A3000 Node:
Role in PowerScale Family:
The A3000 is an archive node designed for high-capacity, cost-effective storage.
Physical Characteristics:

It has a high-density form factor to maximize storage capacity within a minimal rack space.
Titan Rack Options:
Titan-HD (High Density):
Designed for high-density nodes with deep chassis.
Supports higher weight loads due to the dense storage components. Provides enhanced cooling and power distribution suitable for A3000 nodes.
Titan-D and Titan-P:
Titan-D is typically used for general-purpose nodes.
Titan-P may cater to performance-oriented nodes but is not specifically designed for high-density archive nodes like the A3000.
Reasons for Choosing Titan-HD:
Structural Support:
Can handle the weight and depth of A3000 nodes.
Cooling Capabilities:
Optimized airflow to cool densely packed components.
Power Management:
Equipped with power distribution units (PDUs) suitable for high-capacity nodes.
Installation Considerations:
Rack Compatibility:
Using the recommended rack ensures that mounting rails and hardware align properly.
Warranty and Support:
Compliance with Dell's installation guidelines maintains warranty and support agreements.

QUESTION: 26

Which port slot provides management functionality on a PowerScale F600?

PCle slot 3
PCle slot 1
rNDCstot
PCle slot 2

Answer(s): C

Explanation:

On a Dell PowerScale F600 node, the rNDC slot (redundant Network Daughter Card slot) provides management functionality. The rNDC slot hosts the network interface used for node management tasks, including cluster administration and monitoring.

Understanding the F600 Node Architecture:
All-Flash Storage:

The F600 is an all-flash node designed for high performance.
Network Connectivity:
Equipped with various network interface options for data and management traffic.
Role of the rNDC Slot:
Management Port Location:
The rNDC slot houses the management network interfaces.
Dedicated Management Functionality:
Separates management traffic from data traffic to enhance security and performance.
Redundancy Features:
Provides failover capabilities to ensure continuous management access.
Why PCIe Slots Are Less Suitable:
PCIe Slot 1, 2, and 3:
Typically used for data network interfaces or additional hardware components.
Not designated for primary management interfaces.
Management Interface Specificity:
Management ports are specifically assigned to the rNDC slot to standardize configurations across nodes.
Benefits of Using the rNDC Slot for Management:
Simplified Network Design:
Clear separation of management and data networks.
Enhanced Security:
Management interfaces can be placed on a secure network segment.
Consistency Across Clusters:
Facilitates easier administration and support.
Physical Identification:
Location on the Node:
The rNDC slot is located on the back of the F600 node and is typically labeled for easy identification.
Port Types:
May include Ethernet ports designated for management tasks.

What Is the correct order of steps to Install a PowerScale Gen6 in a rack?

See Explanation section for answer.

Answer(s): A

Explanation:

The correct order of steps to install a PowerScale Gen6 in a rack is as follows:
Align the chassis with the rails that are attached to the rack. Slide the first few inches of the back of the chassis onto the supporting ledge of the rails. Release the lift casters and carefully slide the chassis into the cabinet as far as the lift allows. Carefully push the chassis off the lift arms and into the rack. Install two mounting screws at the top and bottom of each rail to secure the chassis to the rack. Comprehensive Detailed Step by Step Explanation with Reference To install a PowerScale Gen6 in a rack, you need to follow a systematic process that ensures both safety and correct placement:
Align the chassis with the rails that are attached to the rack. The chassis must be properly aligned with the rails in the rack, which will support the chassis during the installation process.
Slide the first few inches of the back of the chassis onto the supporting ledge of the rails. Once aligned, slide the back of the chassis onto the supporting ledge of the rails, ensuring the chassis is seated securely.
Release the lift casters and carefully slide the chassis into the cabinet as far as the lift allows. After the chassis is aligned and placed onto the rails, release the lift casters and push the chassis into the rack with controlled force, using the lift mechanism. Carefully push the chassis off the lift arms and into the rack. Once the chassis is positioned on the rails, remove the support from the lift arms, and push the chassis fully into the rack.
Install two mounting screws at the top and bottom of each rail to secure the chassis to the rack. Finally, use screws to secure the chassis at the top and bottom points on both sides, ensuring it is tightly fastened to the rack.
This order ensures a smooth, safe installation and proper alignment in the rack. Following these steps is crucial for the stability of the PowerScale Gen6 system during operation.

QUESTION: 28

Exhibit.

A platform engineer has connected power cables to a Dell PowerScale Gen6 node.
What does the status indicator indicate?

Not functioning
Cold and redundant
Mismatch of voltage or component firmware
On and healthy

Answer(s): D

Explanation:

The status indicator shown in the image contains three status lights: AC, DC, and the general status indicator.
AC (Alternating Current): This green light indicates that the node is receiving proper AC power input. DC (Direct Current): This green light shows that the system is properly converting AC power to DC and that the internal components are receiving the correct power. Status Light (the third light, which is also green): This typically indicates the overall health of the node's power system.
Since all the indicators are green, this confirms that the PowerScale node is receiving power properly, the power conversion is functioning as expected, and the node is in a healthy operational state. Thus, the node is powered on and healthy, making D. On and healthy the correct answer.
