Question
An implementation engineer is expanding an existing VxRail S Series cluster with an additional node. The version of the node is not at the current cluster level but is compatible. What procedure would result in the quickest node addition?
A. RASR Factory Image Upgrade
B. Factory Reset
C. VxRail Node Imaging Management
D. Compute node expansion
Answer
D. Compute node expansion
Explanation
The correct answer is D. Compute node expansion.
A compute node expansion is the process of adding a new node to an existing VxRail cluster. This can be done by adding a new physical node or by converting an existing virtual machine to a physical node.
To add a new physical node, you will need to connect the node to the network and then power it on. Once the node is powered on, you will need to log in to the VxRail Manager and add the node to the cluster.
To convert an existing virtual machine to a physical node, you will need to export the virtual machine from the VxRail Manager and then import it into the VxRail cluster.
Once the node has been added to the cluster, you will need to configure it for your environment. This includes setting up the node’s IP address, hostname, and DNS settings.
After the node has been configured, you can start using it to run your applications.
The following are the steps involved in a compute node expansion:
- Connect the new node to the network and power it on.
- Log in to the VxRail Manager and add the node to the cluster.
- Configure the node for your environment.
- Start using the node to run your applications.
The benefits of a compute node expansion include:
- Increased capacity: Adding a new node to the cluster increases the amount of compute and storage resources available to your applications.
- Improved performance: Adding a new node can improve the performance of your applications by distributing the workload across multiple nodes.
- Increased availability: Adding a new node can increase the availability of your applications by providing redundancy.
The risks of a compute node expansion include:
- Increased complexity: Adding a new node to the cluster increases the complexity of the environment. This can make it more difficult to manage and troubleshoot.
- Increased cost: Adding a new node to the cluster increases the cost of the environment. This includes the cost of the node itself, as well as the cost of the additional infrastructure required to support it.
- Increased security risk: Adding a new node to the cluster increases the security risk of the environment. This is because the new node may be vulnerable to attacks that the existing nodes are not.
Overall, a compute node expansion is a good option for increasing the capacity, performance, and availability of your VxRail cluster. However, it is important to be aware of the risks involved before making a decision.
