Nutanix Customer Success Stories on Transforming IT.

Current Environment Analysis:

The existing AHV cluster has 7 NX-3060-G6 nodes with Intel Skylake processors.

These nodes are distributed across two blocks.

The customer needs to add three more NX-3060-G7 nodes with Intel Cascade Lake processors.

Objective:

Efficiently utilize additional resources by integrating new nodes into the existing infrastructure.

Recommendations:

Expand the existing cluster: The goal is to enhance resource utilization and maintain cluster simplicity by adding the new nodes to the current cluster.

Add a new block populated with the three additional nodes: This approach provides several benefits:

It ensures the new nodes are integrated into the existing management and operational framework.

It leverages the existing network and storage configurations, minimizing setup complexities.

By adding a new block, the existing two blocks remain unchanged, maintaining their current configuration and workloads.

Implementation:

Order and prepare the new nodes: Ensure that the three additional NX-3060-G7 nodes are ready for deployment.

Add the new block to the existing cluster:

Physically rack and connect the new block with the three NX-3060-G7 nodes.

In the Nutanix Prism interface, initiate the process to add the new block to the existing cluster.

The cluster expansion process will automatically incorporate the new nodes into the existing cluster, ensuring seamless integration.

Outcome:

The customer will achieve an efficient expansion of their AHV cluster, utilizing the new resources effectively.

This method ensures minimal disruption and maintains operational consistency across the cluster.

References: For further details on cluster expansion and node addition processes, refer to the Nutanix documentation on cluster management and node integration.

To address the performance concerns of a prospective customer evaluating a hybrid configuration versus an all-flash array, the following Nutanix features should be discussed:

Data Locality:

Nutanix ensures that data is kept local to the node where the VM is running. This reduces latency and increases performance by minimizing the distance data must travel over the network.

Automatic Data Tiering:

Nutanix can automatically move frequently accessed data to faster storage tiers (e.g., SSDs) and less frequently accessed data to slower storage tiers (e.g., HDDs). This ensures that critical data gets the performance benefits of faster storage without the need for an entirely all-flash array.

According to the Nutanix Bible, three File Server VMs (FSVMs) are deployed by default in a Nutanix Files deployment to ensure high availability and load balancing​​.

To logically separate management and data traffic on a Nutanix cluster, the administrator should use Network Segmentation. This feature allows for the isolation of different types of traffic, ensuring that management and data operations do not interfere with each other and enhancing security and performance​​.

Understanding POC Success Criteria:

A Proof of Concept (POC) must have clear, measurable success criteria to demonstrate the value and effectiveness of the proposed solution.

Measurable Criteria for POC:

Deployed 100 desktops on AHV using Citrix MCS plugin:

Explanation: Successfully deploying a significant number of desktops (100) using Citrix MCS on Nutanix AHV showcases the capability and scalability of the solution.

Scenario Understanding:

The administrator needs to verify if all network cards associated with Bridge0 are being utilized in a Nutanix AHV Cluster VDI environment.

Menus to Check Network Configuration:

Option A: Host NICs tab in Hardware menu:

This tab provides detailed information about the physical NICs on each host, including their status, speed, and which bridge they are associated with.

Option B: Host view in Network menu:

This view offers a summary of the network configuration for each host, including the active bridges and the associated NICs. It allows administrators to see if all NICs are being used correctly and if Bridge0 is correctly configured across the hosts.

Evaluation of Other Options:

Option C: 1.0 Metrics tab VM menu:

This option is related to VM metrics and does not provide detailed information on the physical NICs or their utilization.

Option D: Network Configuration item in Setting menu:

This option is used for configuring network settings but does not provide detailed utilization information of the NICs associated with a specific bridge like Bridge0.

Conclusion:

The correct menus to check the current network configuration and utilization of NICs are the Host NICs tab in the Hardware menu and the Host view in the Network menu.

Concerns Addressed:

Product Supportability: Addressing the prospect's concerns about support and partnership is critical.

TSAnet:

TSAnet(Technical Support Alliance Network) is an industry cooperative that provides multi-vendor support. Nutanix's participation in TSAnet ensures coordinated support efforts across vendors, including HPE (Nutanix Support Resources)​​.

Nutanix Software Only HCL:

TheNutanix Software Only Hardware Compatibility List (HCL)provides a comprehensive list of supported hardware, ensuring that Nutanix software can be reliably deployed on HPE servers. This official documentation helps counter FUD (Fear, Uncertainty, and Doubt) by verifying compatibility (Nutanix HCL)​​.

Conclusion:

Leveraging TSAnet and the Nutanix Software Only HCL provides credible and verifiable evidence to overcome concerns about product supportability and partnership with HPE.

Relocating an AHV cluster to a new datacenter while maintaining the same IPs requires careful preparation to ensure minimal disruption and data integrity. The following steps are essential:

Stop all Nutanix Files clusters:

Nutanix Files clusters must be stopped to ensure that there are no ongoing file operations that could be disrupted during the relocation. This prevents data corruption and ensures a clean shutdown of file services.

Shut down all user VMs in the cluster:

Shutting down all user VMs ensures that there are no active workloads that could be interrupted. This step is crucial to prevent data loss and ensure a smooth transition when the cluster is powered up in the new datacenter.

Reconfigure IPMI and Relocate LDAP (Not Required):

Reconfiguring IPMI is not necessary if the IPMI interfaces are not affected by the physical relocation.

Relocating the linked LDAP server is also unnecessary unless the LDAP server itself is moving or changing its network configuration.

By following these steps, the administrator ensures that the cluster can be relocated safely with minimal risk of data loss or service interruption.

For highly active SQL workloads that write I/Os in 2 MB chunks to a vDisk, compression is the most suitable storage optimization technology. Compression works well with larger I/O sizes and can significantly reduce the storage footprint, providing better capacity optimization. This approach ensures that the large chunks of data are compressed efficiently, maximizing storage utilization and performance​​.
