Balances VMs throughout the cluster when the VM is first powered on: ADS ensures that VMs are optimally placed based on available resources and load distribution when they are started​​.

A. Data Locality:

The concept of data locality in Nutanix ensures that data is always kept close to the VM that uses it, typically on the same node. This reduces latency and provides high performance comparable to, or exceeding, traditional 16Gb Fibre Channel SAN solutions.

Data locality minimizes the need for data to travel over the network, effectively leveraging 10Gb Ethernet for low-latency and high-throughput operations, addressing the storage administrator’s concerns.

To determine the best configuration, we need to calculate the required storage, including the additional 20% growth and the capacity to re-protect in the event of a node failure:

Initial Storage Requirement:

Usable storage required: 15 TiB

Additional storage for 20% growth: 15×0.2=3 TiB15 \times 0.2 = 3 \text{ TiB}15×0.2=3 TiB

Total storage required: 15+3=18 TiB15 + 3 = 18 \text{ TiB}15+3=18 TiB

Storage with Re-protection:

To ensure data protection and availability, Nutanix typically uses a replication factor (RF) of 2, meaning each piece of data is stored twice.

Therefore, the total raw storage needed: 18 TiB×2=36 TiB18 \text{ TiB} \times 2 = 36 \text{ TiB}18 TiB×2=36 TiB

Given these calculations, we should look for a configuration that provides at least 36 TiB of raw storage. Based on typical Nutanix node configurations, Option D provides the best balance of cost and capacity, ensuring that the requirement for 36 TiB of raw storage is met.

B. B (Manual Mode Selection):

In the exhibit, selecting "Manual" mode allows the SE to manually adjust the configuration to fit specific requirements, such as accommodating a specific number of physical host-based software licenses.

To enhance the resiliency of the Nutanix environment against power outages to individual racks, it's essential to implement a strategy that ensures data availability even if an entire rack loses power. Here’s a step-by-step breakdown of the solution:

Current Environment Analysis:

The customer has two NX-3460-G7 blocks and one NX-3160-G7 block in a single rack.

Each block consists of multiple nodes, with a total of nine nodes across these blocks.

Objective:

Increase resiliency to power outages affecting individual racks.

Recommendations:

Move one node from each NX-3460-G7 block to the NX-3160-G7 block: This step is crucial to distribute the nodes across different physical blocks. By doing this, each block will have nodes that can ensure data availability even if a block is compromised.

Distribute the blocks across three separate racks: This ensures that even if one rack loses power, the nodes in the other racks can still maintain data availability and cluster operations.

Enable Rack Awareness: Rack Awareness is a feature in Nutanix that ensures data is distributed in such a way that a rack failure does not lead to data unavailability. When enabled, the system understands the physical location of each node and ensures data replication across different racks.

Implementation:

Physically relocate one node from each NX-3460-G7 block to the NX-3160-G7 block.

Physically distribute the three blocks (NX-3460-G7, NX-3460-G7, NX-3160-G7) across three different racks in the data center.

In the Nutanix Prism interface, enable Rack Awareness to logically inform the cluster of the new rack distribution.

Outcome:

By spreading nodes and blocks across three racks and enabling Rack Awareness, the customer will have increased resiliency. In case one rack loses power, the nodes in the other racks will ensure continuous data availability and cluster operations.

This approach leverages the best practices for ensuring high availability and fault tolerance in a Nutanix environment. It minimizes the risk of data loss or downtime due to power failures in a single rack.

References: For further information and detailed steps on enabling and configuring Rack Awareness, please refer to the Nutanix documentation related to high availability and data protection in multi-rack deployments.

Reclaiming Licenses (Including License Renewal)

You can reclaim and optionally re-apply licenses for nodes in your clusters:

You must reclaim licenses when you plan to destroy a cluster. First reclaim the licenses, then destroy the cluster. You do not need to reclaim Starter licenses. These licenses are automatically applied whenever you create a cluster, including after you have destroyed a cluster.

Return licenses to your inventory when you remove one or more nodes from a cluster. Also, if you move nodes from one cluster to another, first reclaim the licenses, move the nodes, then re-apply the licenses.

You can reclaim licenses for nodes in your clusters in cases where you want to make modifications or downgrade licenses. For example, applying an Ultimate license to all nodes in a cluster where some nodes are currently licensed as Pro and some nodes are licensed as Ultimate. You might also want to transition nodes from Ultimate to Pro licensing.

You must reclaim licenses when you renew licenses. First reclaim the expired licenses, then apply new licenses.

Reseat Disks/Nodes: While reseating might help with connectivity issues, it should be performed with caution and typically after consulting support to avoid data loss or further complications.

Resolve Alerts and Re-import Disks: This step is useful but secondary to ensuring that applications are not negatively impacted. Immediate action should focus on stability and minimizing downtime.

Restart CVMs: Restarting CVMs might help but could also disrupt services and should be a last resort after consulting with support.

Application Status and Support: Checking the status of applications ensures that any critical services are not interrupted, and calling support provides access to Nutanix's expertise to address the hardware issue effectively.

Given the critical nature of hardware issues and the potential impact on the cluster, contacting support while checking the application status is the best course of action to ensure a safe and effective resolution.

1 x 480GB SSD:

For a hybrid cluster running both general-purpose VMs and an ERP application with a 500GB database, having a single 480GB SSD may lead to performance bottlenecks.

Nutanix best practices recommend using multiple SSDs for better I/O performance and redundancy​​​​.

2 x 1GB NIC:

The network interface cards (NICs) with only 1GB capacity each are insufficient for a production environment expected to handle significant data and application traffic.

Nutanix typically recommends 10GB NICs for adequate bandwidth and performance in such scenarios​​.

For network switch discovery in Prism, the following settings are required:

Switch Management IP Address: This is necessary to access and manage the network switch.

AHV Host IP address: This helps in identifying the hosts connected to the network.

SNMP Community Name: This is used for SNMP protocol to monitor and manage the network devices​​​​.

A. Option A:

To configure Sizer for a scenario that requires offsite backup but not remote disaster recovery, with an RTO of 48 hours, RPO of 4 hours, and the ability to restore from the past 5 days of backups, the SE needs to ensure that the Sizer settings reflect these requirements.

Given the prospect's data change rate of 1%, the SE should configure Sizer to handle the daily backup data and the total data retention period. Option A likely represents the configuration that meets these parameters.

References:

Scenario Analysis:

The VM is protected with NearSync Replication, scheduled every 15 minutes, but misses the replication window during nightly backups due to high write volumes.

Expected Behavior:

Option B: Protection Domain transitions back to hourly schedule:

NearSync automatically falls back to a less frequent replication schedule, such as hourly, when it cannot keep up with the 15-minute schedule due to write volume or other issues.

Option D: The system continuously tries to get to the NearSync schedule:

The system does not give up on the NearSync schedule. Instead, it keeps attempting to return to the 15-minute interval as soon as conditions allow (e.g., write volume decreases)​​.

Behavior Explanation:

Hourly Schedule Transition:

When the high write volume prevents the 15-minute replication, NearSync transitions to an hourly schedule to ensure that replication continues, albeit at a reduced frequency.

Continuous Attempt to Return to NearSync:

The system monitors conditions and makes continuous efforts to revert to the NearSync schedule as soon as it becomes feasible.

Conclusion:

The correct options that describe the expected behavior are B and D.
