Configuration settings within vCenter that define performance, replication, and redundancy for virtual machines.

The chosen vSAN storage policy directly impacts the virtual machine's performance and cost due to its defined settings.

Creating secondary copies of vSAN data to ensure disaster recovery by enabling restoration in case of failure.

vSAN offers different replication methods - full, incremental, and differential - each impacting performance.

Regular backups of vSAN data are critical for disaster recovery, with options such as full, incremental, or differential backup methods.

Tracking I/O performance metrics in virtual machines identifies potential issues, bottlenecks, and areas for improvement.

Optimizing virtual machine placement within vSAN-aware clusters with proper storage configuration enhances efficiency.

Securing vSAN data at rest using encryption is crucial for protecting sensitive information in production environments.

A software-defined storage solution built into VMware vSphere, providing high-performance and highly available storage for virtual machines using the compute nodes' local disks instead of dedicated storage arrays.

A group of one or more ESXi hosts that work together to provide vSAN storage.

The interface through which virtual machines access vSAN storage.

Refers to the speed and efficiency of vSAN storage, measured by factors like IOPS and latency.

Regularly checking the health of your vSAN cluster using vCenter tools to identify and address potential issues like capacity, performance, or availability problems.

Proactively monitoring the utilization of vSAN storage, ensuring efficient resource allocation and preventing future issues related to space.

Adding or removing ESXi hosts from a vSAN cluster, carefully planning to maintain performance and availability.

Connecting different storage types (like arrays from various vendors) to vCloud Director for managing VMs and storage.

Techniques to store data across multiple locations, ensuring data availability even if one site fails.

Reducing storage space by eliminating duplicate data and compressing data to store it efficiently.

Protecting sensitive virtual machine data by encrypting it, making it unreadable without the key.

Moving data between different storage tiers (fast SSDs or slower network storage) based on access frequency.

Rules that define storage parameters for VMs and vApps, controlling performance, limits, and availability.

VMs and vApps can inherit storage policies from parent objects or have specific policies applied.

Features within policies that optimize storage utilization, like thin provisioning, compression, and deduplication.

Tracking metrics like I/O latency, throughput, and capacity to identify and resolve performance issues.

Predicting future storage needs and ensuring sufficient capacity to avoid running out of space.

Techniques like optimizing I/O patterns and using hardware acceleration to improve storage performance.

vCloud Foundation 5.2 can be integrated with other storage technologies beyond vSAN, providing flexibility in storage choices.

After performing vSAN maintenance, it's crucial to thoroughly check the health and functionality of the cluster to ensure everything is back to normal.

Always refer to the official vSAN documentation for specific instructions and procedures related to your cluster’s version and configuration.

Going back to normal operations after maintenance requires a specific process, often involving confirmation or execution steps. Refer to the documentation for details.

After maintenance, comprehensive testing is vital. Ensure the cluster and all its components are fully functional and meet expected performance levels.

Rigorous testing after maintenance is key for maintaining operational stability and preventing performance issues in the vSAN cluster.

A state where a vSAN cluster is temporarily taken offline for maintenance tasks, requiring careful preparation and execution to minimize disruption.

Regular assessments of the vSAN cluster's stability and performance, ensuring all components are functioning correctly before maintenance.

Consider the effect of taking a vSAN cluster offline on virtual machines that rely on that storage, potentially causing downtime or performance issues.

Specific steps for transitioning a vSAN cluster into maintenance mode, depending on the cluster configuration, desired isolation level, and administrative tools.

The official guide for vSAN products, providing detailed information on various aspects of vSAN, including maintenance procedures and steps.

The complexity of the vSAN maintenance process is influenced by the vSAN cluster's size, configuration, and any associated settings.

A check to identify potential failures or errors that might hinder successful maintenance, ensuring the cluster is ready for the process.

Recording all maintenance actions and outcomes, including commands used and any issues encountered, for future troubleshooting purposes.

Ensuring new storage devices are compatible with the existing vSAN deployment and ESXi hosts. This might involve matching array family types if applicable.

Carefully considering the capacity needed for the vSAN datastore and planning how much storage to add at a time.

Understanding the expected I/O performance of the new and existing storage and ensuring adequate I/O bandwidth is available for applications.

Planning for redundancy of new storage to ensure high availability and fault tolerance for the datastore.

Making sure the new storage is compatible with the rest of the vSphere environment. This includes checking storage protocols for conflicts.

Expanding the storage capacity of a vSAN datastore by adding new physical disks to the participating ESXi hosts.

Ensuring the added disks are compatible with the vSAN cluster and ESXi hosts before incorporating them.

Planning how the new storage capacity will be used, considering factors like performance and data types.

After adding storage, confirming the new capacity is available and recognized by the vSAN cluster.

Notifications that alert administrators to potential issues within the vSAN cluster, such as disk failures, performance degradation, or connectivity problems.

Enabling vSAN health alerts provides valuable insight into the health and performance of the vSAN datastore, allowing proactive responses to potential issues.

Disabling vSAN health alerts might be considered during planned maintenance or non-critical testing scenarios where the potential disruptive impact of alerts outweighs the benefit of proactive failure monitoring.

Administrators can select specific types of alerts to receive, while suppressing others, creating a manageable alert stream.

vSAN health alerts are categorized by severity, with levels like critical, high, medium, and low, helping administrators to prioritize the issues needing attention.

Well-defined alert thresholds determine when an alert is triggered, ensuring accurate and relevant notifications.

vRealize Operations, integrated into vCloud Foundation, can consolidate alert information and provide advanced diagnostics, enhancing alert management.

The vCloud Foundation platform provides tools for suppressing, filtering, or handling alerts to accommodate specific scenarios.
