Study Notes
High Availability (HA) Requirements
- A two-node cluster requires shared storage to maintain HA in case of a node failure.
- Implementing quorum-based clustering can help ensure continued operations despite failures.
Effect of Enabling Flash Mode
- Enabling Flash mode improves performance by leveraging SSDs for faster data access.
- This setting can decrease latency and increase the speed of read/write operations.
Application of Policies in Prism Element
- Policies such as replication factor and storage efficiency settings are applied to the storage container object.
- These policies help manage data protection and resource usage effectively.
Nutanix Storage Service for Unstructured Data
- Nutanix Objects is a storage service capable of storing Petabytes of unstructured data.
- It supports S3 APIs, allowing seamless integration with various applications.
Creating a Single Chart for Storage Usage
- An administrator should utilize the "Container Usage" report feature to consolidate logical usage across multiple storage containers into a single chart.
- This report provides a comprehensive overview of storage allocation and consumption.
Automatic Cluster Response to Node Failure
- Upon detecting a node failure in a Nutanix AHV-based cluster, the system will automatically redistribute workloads across the remaining nodes.
- This action helps maintain performance and availability while minimizing downtime.
Data Efficiency Mechanism
- Nutanix uses Erasure Coding as a modern data efficiency mechanism, replacing the traditional Replication Factor for suitable data sets.
- This method optimizes storage use while maintaining data redundancy.
Scale-Out Storage Technology
- Nutanix’s scale-out storage technology is based on distributed file systems, allowing capacity and performance to increase linearly as new nodes are added.
- This technology underpins the hyper-converged infrastructure, enhancing scalability.
Technology for Application and Data Mobility
- Nutanix’s Calm enables applications and data to move freely between different runtime environments.
- This facilitates multi-cloud deployments and hybrid cloud scenarios.
Role-Based Access Control (RBAC) Configuration
- Role-based access control (RBAC) can be configured in the Nutanix Prism interface.
- Administrators can define user roles and permissions to enhance security and data management.
