Microsoft Azure Stack HCI operating system is factory installed on all the AX nodes and does not include upfront license cost. The factory install also enables the following Windows features:
- Failover Clustering
- FS Data Deduplication
Note: Deduplication is supported but based on your requirement check whether it is necessary or not.
- Datacenter Bridging
- Bit locker
Windows Server 2019 and Windows Server 2022 data centers continue to be available on systems (VMs) with Azure Stack HCI experience as a Secondary operating system. Enough licenses should be included to cover all cores configured in the node.
Azure Stack HCI licensing is billed monthly like other Azure services and only enabled cores are billed, allowing customers to disable cores in the BIOS to reduce costs. This is a great technique for early cost savings with the ability to enable more compute capability as the node utilization grows.
