Correct Answer
It is only supported on Premium SSD managed disks attached to M-series VMs, and the disk cannot use ReadWrite host caching
Why This Answer Is Correct
Azure Write Accelerator is exclusively available for M-series VMs and only works with Premium SSD Managed Disks (not Ultra Disks or Standard SSDs). When Write Accelerator is enabled on a disk, host caching for that disk must be set to None (not ReadWrite or ReadOnly). It significantly reduces write latency for HANA log volumes by buffering writes in a dedicated write-back cache. It is critical for SAP HANA certification compliance on Azure M-series VMs.
