The Dell EMC Cloud for Microsoft Azure Stack Hub solution is a fully engineered hybrid-cloud platform that is built on a Microsoft hybrid-cloud-integrated architecture. This architecture consists of common modular building blocks that scale linearly 4 to 16 nodes in a scale unit (SU). Cloud for Microsoft Azure Stack Hub provides a simple, cost-effective solution that delivers multiple performance and capacity options to match any use case. The solution supports a wide variety of cloud-native applications and workloads.
The integrated system is based on Microsoft Azure Stack Hub software and built with Intel Xeon Gold and Platinum processors. The solution enables customers to start small and grow, scaling capacity and performance with minimal disruption. Scaling in predictable units ensures a “pay-as-you-grow” approach for future growth.
The following figure shows the solution architecture.

The solution is built around an SU. At the SU, the solution is an Azure Stack Hub integrated system with the option to start with 4, 8, 12, or 16 nodes. Within the SU, the solution provides flexibility at a component level to optimize processor, memory, storage capacity, and caching ratios.
Azure Stack Hub is an extension of Azure, bringing cloud computing to on-premises environments. You can build applications across hybrid-cloud environments, balancing flexibility and control. You can build applications using a consistent set of Azure services. You can speed up cloud-application development by building on application components from the Azure Marketplace, including open-source tools and technologies.
The Dell Technologies hardware life-cycle host (HLH) is designed to enable monitoring and updates for Azure Stack Hub. The HLH is a Dell EMC PowerEdge R640 management server. The HLH contains Dell Technologies management software and tools to enable server and network monitoring, and “call-home” capability. HLH also provides patch and update capability for the components that Dell Technologies provides.

The Dell EMC PowerEdge R840 is a four-socket, 2U rack server that is designed to run complex workloads using highly scalable memory, I/O capacity, and network options. The PowerEdge R840 provides configurability to create an optimal configuration that balances solid-state drive (SSD) and hard-disk capacity.
The PowerEdge R840 configurations are not expandable beyond the purchased configuration.
The Dell EMC PowerEdge R740xd is a high-performance software-defined storage server. It is a two-socket, 2U rack server that is designed to run complex workloads by using highly scalable memory, I/O capacity, and network options. The PowerEdge R740xd provides configurability to create an optimal configuration that balances SSD and hard-disk capacity.
The Dell EMC PowerEdge R640 is a high-performance software-defined storage server. It is a two-socket, 1U rack server that is designed to run complex workloads by using highly scalable memory, I/O capacity, and network options. The PowerEdge R640 provides an optimal server for use as an all-flash SU.
Dell EMC Tactical Microsoft Azure Stack Hub is a ruggedized and field-deployable product for Microsoft Azure Stack Hub. The product core components (servers, switches, and so on) are contained in transit cases called “pods.” The product core components are identical to our currently shipping all-flash data center Azure Stack Hub offering.
A pod is a 4U rack container that has smaller dimensions than a regular 4U rack. There is one management pod and two scale-unit (SU) pods. The management pod includes the hardware life-cycle host (HLH), 25 GbE Top-of-Rack (ToR) switches, and a baseboard management switch.
Each SU pod holds two PowerEdge R640 SU servers. One PowerEdge R640 server occupies a 2U rack space in the pod. Each PowerEdge R640 server can be added up to the full node limits of a Microsoft Azure Stack Hub all-flash SU node.
