Dell EMC Integrated System for Microsoft Azure Stack Hub has been at the forefront in bringing Azure to customer datacenters, enabling customers to operate their own region of Azure in a secure environment that addresses their data sovereignty and performance needs.
As data growth explodes at the edge, many of our customers are looking to process PB scale data in the context of file, image/video processing, analytics, simulation, and learning. With Azure Stack Hub, built on hyperconverged infrastructure (HCI), the need for external storage to handle this growth in data was critical. Additionally, for applications that use file storage with CIFS/NFS today, Azure files storage service is currently not supported.
As we set out to identify the right storage subsystem that met our customers’ needs (with performance, multi-tenancy, multi-petabyte scale-out storage, and advanced data management features), we did not have to look far. Dell Technologies has a large product portfolio that enables us not only to integrate with other infrastructures but to innovate in other areas to deliver the Azure consistent experience our customers expect.
With newly announced Azure Stack Hub integration with Dell EMC PowerScale, customers can run their Azure IaaS and PaaS on-premises while connecting to data that is generated and stored locally. In the context of Azure consistency, depending on your application needs, there are two ways to consume this storage.
- Azure Consistent Storage (ACS): Applications that are using Azure Block Blob storage
- Integrated NAS (File Storage): NFS and CIFS
Here are some highlights about the choices and differences:
Regardless of your protocol of choice, you have two personas engaged:
- The Azure Stack Hub Cloud administrator (screen below) is responsible for creating offers, quotas, and plans to offer the underlying storage, via subscriptions, to Azure tenants.
- The Azure Stack tenant can consume storage and be metered and billed consistent with other Azure Services. All of this, without having to manage anything in PowerScale.
With this strategy, our customers can tap into external PB storage to consume Azure Block Blob or Files via CIFS/NFS while maintaining the Azure consistent experience. Additionally, for customers looking to keep their applications in the public cloud while maintaining their data on-premises, Dell Technologies Cloud PowerScale extends OneFS running on-prem to Azure.
To read more about it, see this solution brief:
With the work Dell Technologies has been doing with Azure and Azure Stack Hub, your data is secure and compliant. You also have the choice to run your application in Azure or Azure Stack Hub and connect to your on-prem data without sacrificing bandwidth or latency.

Dell EMC Integrated System for Microsoft Azure Stack Hub has been extending Microsoft Azure services to customer-owned data centers for over three years. Our platform has enabled organizations to create a hybrid cloud ecosystem that drives application modernization and to address business concerns around data sovereignty and regulatory compliance.
Dell Technologies, in collaboration with Microsoft, is excited to announce upcoming enhancements that will unlock valuable, real-time insights from local data using GPU-accelerated AI and ML capabilities. Actionable information can be derived from large on-premises data sets at the intelligent edge without sacrificing security.
Partnership with NVIDIA
Today, customers can order our Azure Stack Hub dense scale unit configuration with NVIDIA Tesla V100S GPUs for running compute-intensive AI processes like inferencing, training, and visualization from virtual machine or container-based applications. Some customers choose to run Kubernetes clusters on their hardware-accelerated Azure Stack Hub scale units to process and analyze data sent from IoT devices or Azure Stack Edge appliances. Powered by the Dell EMC PowerEdge R840 rack server, these NVIDIA Tesla V100S GPUs use Discrete Device Assignment (DDA), also known as GPU pass-through, to dedicate one or more GPUs to an Azure Stack Hub NCv3 VM.
The following figure illustrates the resources installed in each GPU-equipped Azure Stack Hub dense configuration scale unit node.
This month, our Dell EMC Azure Stack Hub release 2011 will also support the NVIDIA T4 GPU – a single-slot, low-profile adapter powered by NVIDIA Turing Tensor Cores. These GPUs are perfect for accelerating diverse cloud-based workloads, including light machine learning, inference, and visualization. These adapters can be ordered with Dell EMC Azure Stack Hub all-flash scale units powered by Dell EMC PowerEdge R640 rack servers. Like the NVIDIA Tesla V100S, these GPUs use DDA to dedicate one adapter’s powerful capabilities to a single Azure Stack Hub NCas_v4 VM. A future Azure Stack Hub release will also enable GPU partitioning on the NVIDIA T4.
The following figure illustrates the resources installed in each GPU-equipped Azure Stack Hub all-flash configuration scale unit node.
Partnership with AMD
We are also pleased to announce a partnership with AMD to deliver GPU capabilities in our Dell EMC Integrated System for Microsoft Azure Stack Hub. Available today, customers can order our dense scale unit configuration with AMD Radeon Instinct MI25 GPUs aimed at graphics intensive visualization workloads like simulation, CAD applications, and gaming. The MI25 uses GPU partitioning (GPU-P) technology to allow users of an Azure Stack Hub NVv4 VM to consume only a portion of the GPU’s resources based on their workload requirements.
The following table is a summary of our hardware acceleration capabilities.
An engineered approach
Following our stringent engineered approach, Dell Technologies goes far beyond considering GPUs as just additional hardware components in the Dell EMC Integrated System for Microsoft Azure Stack Hub portfolio. We apply our pedigree as leaders in appliance-based solutions to the entire lifecycle of all our scale unit configurations. The dense and all-flash scale unit configurations with integrated GPUs are designed to follow best practices and use cases specifically with Azure-based workloads, rather than workloads running on traditional virtualization platforms. Dell Technologies is also committed to ensuring a simplified experience for initial deployment, patch and update, support, and streamlined operations and monitoring for these new configurations.
There are a couple of additional details worth mentioning about our new Azure Stack Hub dense and all-flash scale unit configurations with hardware acceleration:
- The use of the GPU-backed N-Series VMs in Azure Stack Hub for compute-intensive AI and ML workloads is still in preview. Dell Technologies is very interested in speaking with customers about their use cases and workloads supported by this configuration. Please contact us at firstname.lastname@example.org to speak with one of our engineering technologists.
- The Dell EMC Integrated System for Microsoft Azure Stack Hub configurations with GPUs can be delivered fully racked and cabled in our Dell EMC rack. Customers can also elect to have the scale unit components re-racked and cabled in their own existing cabinets with the assistance of Dell Technologies Services.
Resources for further study
- At the time of publishing this blog post, only the NCv3 and NVv4 VMs are available in the Azure Stack Hub marketplace. The NCas_v4 currently is not visible in the portal. Please proceed to the Azure Stack Hub User Documentation for more information on these VM sizes.

Automated Detection of Server Configuration Drift
Security and compliance are key design principles of Microsoft Azure Stack Hub. The Dell EMC Integrated System for Microsoft Azure Stack Hub is engineered to meet Compliance, Regulatory, and Policy requirements of our customers.
Security posture on Dell EMC Integrated system for Microsoft Azure Stack Hub is implicit to our automated lifecycle management. Our goal is to extend and complement Microsoft’s strategy of baselining and remediating their security posture with a comprehensive drift and remediation strategy for all of our Azure Stack Hub elements.
The Automated Server Config Drift Detection feature, enabled on Dell EMC OpenManage Enterprise as part of the Dell EMC Patch and Update Automation - 2004 Release, ensures Configuration Compliance as instituted by Microsoft and Dell EMC.
Monitor & Detect, Notify, and Remediate Server configuration Drift on Azure Stack Hub are the three key outcomes of the Automated Server config drift detection feature.
- Compliance Monitoring is kicked off by automated discovery of HLH and Scale Unit nodes on Dell EMC OpenManage Enterprise (Figure 1, below).
- Configuration integrity is maintained by enabling compliance baseline templates for the HLH and Scale Unit Nodes on OpenManage Enterprise in order to track drift (Figure 2).
- Customers can view Compliance reports which display whether Server settings conform to the configuration baseline or not (Figure 3).
- Drift from any of the Server settings applied at initial deployment on the HLH or Scale Unit nodes will be automatically detected, resulting in the node being tagged as Non-Compliant (Figure 4).
- Server-drift Notification Alerts generated on OpenManage Enterprise are sent proactively via Dell Support Assist Enterprise (SAE) to Dell Technologies support.
- Customers can call Dell EMC Support to remediate non-compliance to ensure that the health and compliance status of their Azure Stack Hub continues to stay green.
