Pull request overview
This PR updates the NVMe overview documentation by adding an FAQ section to help readers understand NVMe-enabled managed disks, enablement options, prerequisites, and related resources.
Changes:
- Added a new FAQs section covering NVMe disk controller concepts, enablement, prerequisites, and operational considerations.
- Added a “Related resources” reference list to supporting Learn and Azure Updates pages.

| • Higher IOPS and throughput (multi-GBps, hundreds of thousands of IOPS depending on VM size). | ||
| • Lower latency compared to SCSI. | ||
| • Better performance/price efficiency for disk-heavy workloads. |

| #### What is the NVMe-enabled DiskControllerType in Azure? | ||
|
|
||
| NVMe-enabled DiskControllerType is a disk interface option that allows Azure Managed Disks (OS and Data disks) to be attached using an NVMe controller instead of the traditional SCSI controller, providing significantly higher IOPS and throughput. |

| #### How do I enable NVMe DiskControllerType when creating a VM? | ||
| Specify DiskControllerTypes = ["NVMe"] during VM creation using Azure Portal, CLI, PowerShell, Bicep, or ARM template. |

| #### Can we enable NVMe for VM Scale Sets (VMSS)? | ||
|
|
||
| Yes, VMSS supports the same diskControllerTypes property for VM profiles, provided the chosen SKU is Ebsv5/Ebdsv5. |

| 1. Stop and deallocate the VM. | ||
| 2. Update diskControllerTypes to "NVMe". | ||
| 3. Ensure the OS image supports NVMe drivers. |

| • VM must be Ebsv5 or Ebdsv5. | ||
| • OS image must support NVMe. | ||
| • VM must be deallocated before modification. | ||
| • Disks and OS must have NVMe drivers. |
