The Storage Overview dashboard provides visibility into capacity, performance, and health across vSAN and non-vSAN datastores. Administrators can track datastore utilization, latency, throughput, and availability from a single pane of glass.

Comprehensive and Detailed Explanation From Exact Extract:
When scaling an NSX Edge cluster in VMware Cloud Foundation using SDDC Manager, the following preparatory steps are explicitly required as per the official documentation:
Assign a unique management IP for each Edge node (A): Each new Edge node must have its own unique management IP address for proper identification and network communication.
Assign two Tunnel Endpoint (TEP) addresses for each Edge node (B): Two TEP addresses are needed for overlay network connectivity to ensure redundancy and optimal traffic flow.
Verify DNS records have been added for each new Edge node (D): Proper DNS records must exist for management and operational connectivity, as DNS resolution is critical for Edge node communication and cluster integration.
Adding uplinks or placing the Edge cluster in maintenance mode are not prerequisites for adding new Edge nodes, according to the preparation requirements detailed in VMware documentation.

Role-Based Access Control (RBAC) in vCenter is used to define and manage user roles and permissions. It allows administrators to control who can access specific resources and perform actions within the vCenter environment. RBAC ensures that users only have access to the areas and tasks they are authorized to interact with, enhancing security and management.

Running a compatibility pre-check validates that vCenter, ESXi, NSX, and other components meet the requirements for the target VCF version.
Backing up SDDC Manager, vCenter, NSX, and other critical components ensures you can roll back if the upgrade encounters issues.
The SDDC Manager UI provides an orchestrated upgrade workflow, downloading and applying the required bundles in the correct order.

The VCF 9.0 Upgrade Guide specifies required components when converting from a vSphere- only deployment to full VCF. The must-deploy services include:
VCF Operations fleet management - central monitoring of multiple instances.
VCF Operations - core operational monitoring platform.
VCF Operations Collector - required for data ingestion from vSphere, NSX, and vSAN.
The Identity Broker is already embedded with VCF 9.0 SSO, while VCF Operations for Logs and Networks are optional add-ons for extended visibility.
