Flexible Deployment

Azure Stack HCI works on over 150 hardware configurations.

Azure Stack HCI has a diversity of deployment options. If you’re looking for minimum cost, you can likely use existing hardware depending on it’s generation. If you’re looking to buy new equipment, you’ll have over 150 validated solutions to choose from. You can also customize nearly all the solutions by varying the processor, memory, storage, and network speed.

Accommodate the needs of your business, whatever the size, with validated node solutions.	Maximize outcomes when you run Azure Stack HCI on new hardware.
Get the best performance with integrated system solutions that are pre-wired, pre-racked and pre-configured.	Support Azure Stack HCI with existing or repurposed hardware that meets Azure Stack HCI-validated node requirements.

A variety of solutions

Nodes are available with Intel NVME flash storage and Intel Optane persistent memory for extremely high performance.

With the variety of validated node solutions comes a wide range of cores, from 4 cores for ROBO to 28 cores per socket for large datacenters.

The newest QLC flash NVMe storage offerings provide high-performance large storage when paired with Intel Optane caching tier.

Functional Advantage of Azure HCI Stack over Azure:

Network

Internet connection speed limitation.

QOS on connection speed within and
outside of Azure.

Internet uptime, which is normally good,
still being a limitation.

I/O

The data transfer speeds would be only limited by IOPS capability of the hardware, which is not the case with native Azure.

More Enterprise ready.

Local, core infra is a must for any IT to function independently, which demands AD in Azure HCI Stack/Private Cloud/Stand Alone Server Vs Azure AD where the working is not seamless.
Imagine a firewall sitting locally doing an AAA on an Azure AD.
On the same lines the following benefit greatly from local AD.

DNS/DHCP

Desktops

Laptops

Print Server

The below IT assets usually have a lesser update frequency and a larger attack area/probability when exposed, adding one more reason to have AD in the local.

Printer

IP Phone

NVR

Door Access

Mobile Devices

POS Machines.
