NSX can use a dedicated or shared fabric for networking virtualization. Dedicated fabrics are for unique environments, while shared fabrics work for similar workload domains.

vSAN is a software-defined storage solution built into ESXi, offering a unified platform for storage and VM management. It simplifies storage administration by using storage policy-based management (SPBM) to apply consistent rules to VMs and disks.

vSAN integrates storage and VM administration by unifying storage and VM management. It enables VM admins to manage storage policies for their individual VMs, eliminating the need for separate storage specialists.

A vSAN storage policy defines a set of rules enforced on a VM or virtual disk. These rules specify performance, capacity, and redundancy requirements for the VM's storage.

vSAN significantly improves monitoring and visibility by providing native insights into storage health and performance, making it easier to diagnose and resolve issues.

A workload domain is a logical grouping of VMs within a vSphere environment. It helps organize and manage workloads in a more efficient and scalable manner.

To create a vSAN cluster, you need at least 3 ESXi hosts with local storage. You can then use the vSphere Client to configure the cluster and define storage policies.

The SDDC Manager is a critical tool for managing vSAN clusters in VCF. It enables you to add hosts, commission them, and manage other aspects of the vSAN environment.

Always use the SDDC Manager to add hosts to a vSAN cluster. Ensure that the newly added hosts are using the same network pool as the existing hosts in the cluster.

ESA (Express Storage Architecture) is the recommended vSAN configuration. It simplifies the storage layout, eliminating the need for a separate cache tier when using all SSDs. OSA (Original Storage Architecture) is an older configuration with separate disk groups for cache and capacity tiers.

vSAN in VCF offers advantages such as extending virtualization to the storage layer, automating vSAN lifecycle management, and providing high availability and scalability for virtual machines through its distributed storage architecture.

Key components of vSAN include local disks on each host, a dedicated network for vSAN traffic, and a VMkernel interface on each host that's enabled for vSAN. These components work together to create the pooled datastore.

The VMkernel interface is a dedicated network interface on each host that allows vSAN to communicate with other hosts and manage storage operations. It's crucial for maintaining the integrity and performance of the distributed storage.

A dedicated network ensures that vSAN traffic is prioritized and isolated from other network traffic, improving storage performance and minimizing the impact of other network activities.

For single-copy redundancy in vSAN, you need at least 3 hosts. For double-copy redundancy, you need at least 5 hosts. These minimum counts ensure data protection and high availability.

ESA (Express Storage Architecture) is the recommended vSAN configuration, especially when using all SSDs. It simplifies the storage layout and eliminates the need for a separate cache tier, resulting in improved performance and reduced management complexity.

Modify a Network Pool by changing its name, adding IP address ranges, but you cannot delete it if any addresses are in use.

A Network Pool can only be deleted after ensuring all IP addresses within it are unused. The network pool created during initial configuration cannot be deleted.

A Network Pool is created using a wizard, specifying name, network types, VLAN ID, MTU, subnet information, and a valid IP address range from the subnet.

Preparing a workload domain involves creating or adding to an existing one, pre-imaging with the right ESXi version, resolving DNS, and enabling NTP/Syslog.

Designing workload domains based on factors like hardware compatibility, storage configuration, and out-of-band management.

A storage method where data is distributed and spread across multiple hosts, offering high availability and scalability.

A group of hosts that share storage resources using vSAN, providing a high-availability and fault-tolerant storage solution.

Specifies the type of storage used for a workload domain, including VSAN, NFS, VMFS on FC, or VVOL.

vSAN stands for Virtual SAN, which is a software-defined storage solution built into ESXi. It simplifies storage administration by providing a unified platform for managing storage and virtual machines.

The main benefit of vSAN is that it integrates storage and VM administration. This eliminates the need for separate storage specialists and empowers VM administrators to manage storage policies directly for their VMs.

SPBM in vSAN allows you to define a set of rules that apply to a VM or virtual disk. These rules specify performance, capacity, and redundancy requirements for the VM's storage.

A vSAN cluster requires at least 3 ESXi hosts with local storage. This allows data replication and redundancy to ensure high availability.

The SDDC Manager is essential for managing vSAN clusters within a VCF environment. It helps add hosts, commission them, and oversee various aspects of the vSAN infrastructure.

Always use the SDDC Manager to add hosts to a vSAN cluster. Ensure that the new hosts utilize the same network pool as existing hosts to maintain a consistent network environment.

ESA (Express Storage Architecture) is the recommended vSAN configuration. It simplifies storage layout, eliminating the need for separate cache tiers, especially when using all SSDs. OSA (Original Storage Architecture) is an older configuration with distinct disk groups for cache and capacity tiers.

Integrating vSAN with VCF offers advantages such as extending virtualization to the storage layer, automating vSAN lifecycle management, and enabling high availability and scalability for virtual machines through its distributed storage architecture.

vSAN is a software-defined storage solution used in VCF (Virtual Cloud Foundation) for managing storage in a virtualized environment. It replaces physical storage with virtual storage, enabling centralized management and high availability.

Express Storage Architecture (ESA) is the recommended configuration for vSAN in VCF. It simplifies storage management by using all SSDs, eliminating the need for a separate cache tier, and improving storage performance.

Original Storage Architecture (OSA) is an older vSAN configuration that uses separate disk groups for cache and capacity tiers. It's less efficient and more complex than ESA, and not recommended for new deployments.

The VMkernel interface is a dedicated network interface on each vSAN host that manages vSAN communication and storage traffic. It ensures efficient and isolated vSAN network operation.

A dedicated network is required for vSAN traffic to guarantee optimal performance and prevent interference with regular network traffic. It ensures fast communication between vSAN hosts for storage management tasks.

vSAN offers data redundancy to protect against host failures. It uses a minimum of 3 hosts for single-copy redundancy and 5 hosts for double-copy redundancy, ensuring data availability even if a host fails.

The process of adding a host to an existing workload domain or creating a new workload domain. It involves prepping the host with the correct ESXi version, DNS resolution, and configuring network pools.
