Welcome to Random Short Take #34. Some really good players have worn 34 in the NBA, including Ray Allen and Sir Charles. This one, though, goes out to my favourite enforcer, Charles Oakley. If it feels like it’s only been a week since the last post, that’s because it has.
April Fool’s is always a bit of a trying time, what with a lot of the world being a few timezones removed from where I live. Invariably I stop checking news sites for a few days to be sure. Backblaze recognised that these are strange times, and decided to have some fun with their releases, rather than trying to fool people outright. I found the post on Catblaze Cloud Backup inspiring.
VMware vSphere 7 recently went GA. Here’s a handy article covering what it means for VMware cloud providers.
Speaking of VMware things, John Nicholson wrote a great article on SMB and vSAN (I can’t bring myself to write CIFS, even when I know why it’s being referred to that way).
Scale is infinite, until it isn’t. Azure had some minor issues recently, and Keith Townsend shared some thoughts on the situation.
StorMagic recently announced that it has acquired KeyNexus. It also announced the availability of SvKMS, a key management system for edge, DC, and cloud solutions.
Joey D’Antoni, in collaboration with DH2i, is delivering a webinar titled “Overcoming the HA/DR and Networking Challenges of SQL Server on Linux”. It’s being held on Wednesday 15th April at 11am Pacific Time. If that timezone works for you, you can find out more and register here.
So what’s the difference between Azure Stack and Azure Stack HCI? You can think of Azure Stack as an extension of Azure – designed for cloud-native applications. The Azure Stack HCI is more for your traditional VM-based applications – the kind of ones that haven’t been refactored (or can’t be) for public cloud.

The Azure Stack HCI program has fifteen vendor partners on launch day, of which Axellio is one.
Miller describes the Axellio solution as “[n]ot your father’s HCI infrastructure”, and Axellio tell me it “has developed the new FabricXpress All-NVMe HCI edge-computing platform built from the ground up for high-performance computing and fast storage for intense workload environments. It delivers 72 NVMe SSDS per server, and packs 2 servers into one 2U chassis”. Cluster sizes start at 4 nodes and run up to 16. Note that the form factor measurement in the table below includes any required switching for the solution. You can grab the data sheet from here.

It uses the same Hyper-V based software-defined compute, storage and networking as Azure Stack and integrates on-premises workloads with Microsoft hybrid data services including Azure Site Recovery and Azure Backup, Cloud Witness and Azure Monitor.
Thoughts and Further Reading
When Microsoft first announced plans for a public cloud presence, some pundits suggested they didn’t have the chops to really make it. It seems that Microsoft has managed to perform well in that space despite what some of the analysts were saying. What Microsoft has had working in its favour is that it understands the enterprise pretty well, and has made a good push to tap that market and help get the traditionally slower moving organisations to look seriously at public cloud.
Azure Stack HCI fits nicely in between Azure and Azure Stack, giving enterprises the opportunity to host workloads that they want to keep in VMs hosted on a platform that integrates well with public cloud services that they may also wish to leverage. Despite what we want to think, not every enterprise application can be easily refactored to work in a cloud-native fashion. Nor is every enterprise ready to commit that level of investment into doing that with those applications, preferring instead to host the applications for a few more years before introducing replacement application architectures.
It’s no secret that I’m a fan of Axellio’s capabilities when it comes to edge compute and storage solutions. In speaking to the Axellio team, what stands out to me is that they really seem to understand how to put forward a performance-oriented solution that can leverage the best pieces of the Microsoft stack to deliver an on-premises hosting capability that ticks a lot of boxes. The ability to move workloads (in a staged fashion) so easily between public and private infrastructure should also have a great deal of appeal for enterprises that have traditionally struggled with workload mobility.
Enterprise operations can be a pain in the backside at the best of times. Throw in the requirement to host some workloads in public cloud environments like Azure, and your operations staff might be a little grumpy. Fans of HCI have long stated that the management of the platform, and the convergence of compute and storage, helps significantly in easing the pain of infrastructure operations. If you then take that management platform and integrate it successfully with you public cloud platform, you’re going to have a lot of fans. This isn’t Axellio’s only solution, but I think it does fit in well with their ability to deliver performance solutions in both the core and edge.
