 To get started with NC A100 v4 VMs, refer to [HPC Workload Configuration and Optimization](configure.md) for steps including driver and network configuration.
 
-Due to increased GPU memory I/O footprint, the NC A100 v4 requires the use of [Generation 2 VMs](generation-2.md) and marketplace images. While the [Azure HPC images](configure.md) are strongly recommended, Azure HPC Ubuntu 20.04 and Azure HPC CentOS 7.9, RHEL 8.8, RHEL 9.2, Windows Server 2019, and Windows Server 2022 images are supported.
