Nutanix NCSE-Core - Nutanix Certified Systems Engineer-Core (NCSE-Core 6.8)

Problem Analysis:

The prospect experiences unplanned downtime due to hardware failures.

Notifications from their SNMP-based monitoring solution have been ignored due to communication issues.

Nutanix Pulse:

Pulse provides proactive support and monitoring for Nutanix clusters.

It automatically sends cluster health and performance data to Nutanix support, enabling quick issue resolution.

This feature can ensure critical alerts and notifications are not missed, improving overall system reliability.

Conclusion:

Highlighting Pulse helps address the key pain points of unplanned downtime and missed notifications, ensuring better system management and support.

Customer Requirement:

Failover capability to a secondary datacenter with an RPO and RTO of no more than 15 minutes.

Round trip latency between sites can reach up to 6ms.

Nutanix Feature:

NearSync: This feature provides a low RPO/RTO disaster recovery solution with support for low-latency inter-site communication.

Explanation:

NearSyncallows for frequent asynchronous replication with very low RPOs (as low as 1 minute) and ensures rapid recovery times.

It is designed to handle round trip latencies up to 6ms, making it suitable for the customer’s inter-site latency requirements.

Outcome:

NearSync will enable the customer to meet their stringent RPO and RTO requirements, ensuring that VMs can be powered on in the secondary datacenter quickly in the event of a primary datacenter failure.

References: For further details on NearSync capabilities and configuration, refer to Nutanix documentation on disaster recovery and NearSync features.

Understanding Prism Central Requirements:

Prism Central is used to manage multiple Nutanix clusters, providing a centralized management interface for large-scale environments such as a financial institution planning to manage 8000 VMs.

Sizing Guidelines for Prism Central:

To help decrease storage costs for a workload primarily involving an imaging application storing scanned JPEG images, the following Nutanix capabilities should be leveraged:

Erasure Coding: This technology reduces the storage overhead by distributing data and parity across multiple nodes, thus requiring less physical storage while maintaining data resiliency.

Compression: This reduces the storage footprint by compressing the data, which is particularly effective for data like JPEG images that can benefit significantly from compression​​​​.

When using RVTools output for sizing a solution, it is crucial to understand that it represents a point in time snapshot of the environment. This snapshot captures the state of the VMs and hosts at a specific moment, which is important for making accurate assessments and planning based on the current environment's status​​​​.

C. "Shadow IT" that increases the risk of security breaches and brand damage:

The engineering department building their own infrastructure using available hardware, SaaS offerings, and public cloud can lead to "Shadow IT." This increases the risk of security breaches as these systems may not adhere to the company’s security policies and could expose sensitive data.

D. Slow response time from the infrastructure group (SLAs) that could result in product release delays:

The new CIO is trying to gain control of the existing and incoming information systems while supporting an agile environment. Slow response times from the infrastructure group can delay product releases, affecting the company's competitive edge and innovation pace.

Nutanix's unified platform and comprehensive management tools can address these pain points by providing centralized control, enhancing security, and improving agility and response times.

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​​.

D. Automatic Workload Repository Report:

The Automatic Workload Repository (AWR) report provides comprehensive details about Oracle database performance, workload characteristics, and resource utilization. This report is crucial for accurately sizing an environment that includes production Oracle databases.

AWR reports contain historical data on system performance and are used to identify trends, workload patterns, and potential bottlenecks. This information is essential for determining the appropriate resources needed to support the Oracle databases in the Nutanix environment.

References:

Nutanix documentation and Oracle best practices for database sizing recommend using AWR reports for accurate performance and capacity planning.

Zookeeper in Nutanix is responsible for distributing metadata to ensure availability in case of node or block failure. Metadata includes important information about the state and configuration of the cluster, which is crucial for maintaining cluster operations and consistency.

To migrate a VM configured for UEFI-boot from a Nutanix Hyper-V cluster to AHV, the recommended method is to use Nutanix Move. Nutanix Move is a migration tool designed to streamline the process of moving VMs between different hypervisors, including from Hyper-V to AHV. It supports UEFI-boot VMs and ensures that the VM's configuration and data are migrated efficiently and with minimal downtime.
