vCenter Server is a core component of VMware vSphere that centralizes host administration, offering some powerful features that simplify the management process. vCenter Server provides a single pane of glass for your environment and allows access to the installed hosts and their configurations.

To access the ESXi management area, select a host from the vSphere Client. If you navigate from the available tabs, you can access the different configuration areas to set up the host matching the business requirements.

Let's have a look at the main areas:

• Summary: This displays information related to the ESXi, such as the resources in use, the tags, the global configuration, and more.
• Monitor: From this tab, you can track issues and alarms related to configuration problems and check the host's performance information, tasks, and events related to the selected host and the hardware health, to keep the status of the hardware components under control.
• Configure: From this tab, you can modify the host configuration. Storage configuration (such as storage adapters, and storage devices), network settings (such as vSwitches, VMkernel adapters, and TCP/IP), system components (such as host profile, firewall, security profile, and more), and hardware changes can be done in this section.
• Permissions: This tab is used to add permissions that specify users and roles.
• VMs: This shows the list of VMs and VM templates registered in the selected host. Double-click on an object to access its configuration area.
• Datastores: This displays the list of attached storage, showing details such as status, type, storage capacity, and free space.

• Networks: This displays a list of virtual switches and distributed virtual switches configured in the selected host.
• Updates: This displays a list of attached baselines from the Update Manager and the object compliance with the baselines.
