In early 2016 Microsoft announced their Microsoft Azure Stack Hub, along with their new Windows Server 2016, as an extension of the Microsoft Azure Public Cloud. From the beginning, customers sought the benefits of Azure cloud, but deployed within their own datacenter. This new hybrid cloud solution brought them the hyperscale experience of consumption-based computing, along with the ability to run the very same applications you could run on Azure.
This on-premises version of the cloud came with constraints, however. Not all of the same services in Azure are available in Azure Stack. It’s not ‘limitless’ as it is bounded by the capacity and compute contained within a particular customers’ Azure Stack deployment. And that configuration itself is rigidly defined by Microsoft, and available only through a few certified partners, selling predefined bundles of servers, storage and networking.
Up until now, even if they didn’t need more compute or bandwidth, if a customer’s storage needs exceeded that of the configuration that they purchased, they would have to purchase another node (predefined set of compute/storage/networking) or an entire new Azure Stack offering. With Azure Stack, the promise of cloud agility came with strict boundaries.
But that has all changed.
Expand Hybrid cloud capacity with the HPE Storage Extender
The new HPE Storage Extender for Azure Stack Hub solution leverages and delivers scripts and technical guidance on how to expand just the data storage capacity of your Azure Stack Hub environment. This optimized implementation is initially available on HPE Nimble Storage, and works in parallel with Microsoft’s published approach for expanding capacity for Azure Stack Hub by using any iSCSI storage resource.
HPE Nimble Storage brings intelligent, self-managing flash storage to your data center and hybrid cloud environments. It is an ideal platform for your expanded Azure Stack Hub, with high availability and Data Efficiency features, and guarantees both data availability of 99.9999%1 as well as the ability to store more data per terabyte of flash storage than other all-flash arrays. Designed for advanced storage technologies such as NVMe, HPE Nimble Storage delivers industry-leading capacity efficiency as well as a future-proof architecture. You can find guaranteed data-reduction program details in the Store More Guarantee documentation2.
Azure Stack Hub and Data storage
Azure Stack Hub scales between 4 and 16 hybrid nodes and 4 and 8 all-flash nodes. Although the Azure Stack Hub does not contain all of the features of Azure public cloud, it mimics the most common features, and provides an easy transition point for data and applications moving between the cloud and on-premises. The primary method of managing an Azure Stack Hub instance is through an almost identical management portal of the Azure public cloud.
Microsoft Azure Stack Hub currently provisions storage utilizing internal disk from hyperconverged nodes managed by Storage Spaces Direct (S2D). Up to this point, external storage has not been supported under the Microsoft Azure Stack Hub design options; the total capacity and performance available was capped by the maximum number of nodes in the scale unit, the disk drive configurations available from each OEM vendor, and the specific characteristics of the virtual machine type deployed.
The tightly enforced configurations have been at odds with customers and partners requests for flexibility, and specifically for the ability to leverage external storage arrays to support key workloads. Along with additional data capacity, external storage arrays bring with them the ability to migrate and replicate data, along with higher data availability. This is why HPE developed a means to connect HPE Nimble Storage arrays as an external iSCSI storage option, in parallel with Microsoft’s technical template for how to connect to iSCSI storage with Azure Stack Hub3.
HPE brings innovation to Windows with the world’s most intelligent storage
The HPE Storage Extender for Azure Stack Hub solution provides the key elements to enable access to external data capacity, while maintaining a customer’s supported Azure Stack Hub configuration. The solution includes:
- HPE Nimble Storage, officially Windows Server 2019 and 2016 certified
- Windows Server 2016 Datacenter or Windows Server 2019 Datacenter (latest build recommended)
- PowerShell DSC extension
- Custom Script Extension
- Solution Deployment Guide
- HPE InfoSight
HPE InfoSight — the IT industry’s most established AI platform — is the key feature in enabling autonomous, self-managing data storage, and is an embedded part of HPE Nimble Storage, as well as other HPE Storage and Server products. HPE InfoSight has analyzed application patterns in 1,250 trillion data points over the last decade to predict and prevent disruptions across storage, servers, and virtual machines. This has resulted in savings of more than 1.5 million hours of lost productivity due to downtime. HPE InfoSight provides the intelligent foundation for all HPE storage products, creating the industry’s only end-to-end AI capability for self-managing storage.
The HPE Storage Extender for Azure Stack Hub solution is available today. It brings additional data capacity to Azure Stack Hub — without the cost of adding additional compute.
Thanks to HPE Nimble Storage, the HPE Storage Extender for Azure Stack Hub solution is an economical way to access and use more data within your Microsoft Hybrid cloud, while benefitting from improved data management, protection and availability. The solution includes technical guidance and scripts, and is supported by Microsoft as an approach aligned with Microsoft published technical templates.
