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.

- IoT Applications: Device provisioning, tracking and management applications
- Efficient field operations: Disaster Relief, humanitarian efforts, embassies
- Smarter management of mobile fleet assets: Utility and maintenance vehicles
- Tactical scenarios: strategic sites stood up for a specific task, temporary or permanent, that can experience:
- Limited/restricted connectivity: submarines, aircraft, and planes
- Harsh Conditions: combat zones, oil rigs, mine shafts
The final outcome in these environments remains the same: provide always-on cloud services everywhere from a minimal set of local resources.
The question is… how do we make this possible?

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.
