I am not sure to understand one of your points (“it’s a storage thing”) and the implication in your post (“you can run workload on it but you really should not”).
In the “continuum” picture it is clear to me that customers can choose anything from DiY to fully engineered systems (vpex blue/vxRack) and in the spectrum of functionalities scaleio nodes are more on the DiY side. But then, if the customer is more on the DiY side of things, there is really no difference in running workloads using ScaleIO SW on customer-provided HW vs using a ScaleIO Node to do it. No difference, of course, a part from support: the fear of buying the wrong servers with the “sw only” version is common to everybody who has ever built its own PC in the past (forget whole server racks): a single component/driver/expansion can cause your preferred sw not to run, and you will go back and forth between the sw and the hw vendors forever.
So you have a DiY environment that you can use (as any ScaleIO SW install) for both converged and hyper-converged configurations. Is this a hyper-converged appliance? Definitely not. Can you run your applications on it? Just choose the right ScaleIO nodes for your application workload and the answer is Yes. You can and should run your workloads on it. Like on any server with ScaleIO SW on.

To respond to your question b: yes it is illogical. ScaleIO Node is the answer :-)

@Antonio, thanks for the comment, and I love your passion :-)

I hope my comments up front (decided to update based on your and other questions) about why I continue to be emphatic on the simplified answer: ScaleIO SW = SDS. ScaleIO Node = Storage Appliance. VSPEX Blue = HCIA. VxRack = Hyper-Converged Rack Scale System.

The dangerous line that I hope our field follows is not to delude that ScaleIO Nodes are "almost a hyper converged system" (in the hopes of rapidly pushing a sale). It is not. It is very, very close to DIY - but one where we provide the hardware/OS. No more (and there's a lot more in real hyper-converged appliances and rack scale systems), but also no less.

... and I'm sure you would say that the ScaleIO node is the answer based on your role :-)

ScaleIO is great, and customers should really try it. Then decide the best way to use it.

I'm a partner. I have deployed ScaleIO software on commodity servers with PCIe flash... What a fantastic product! One of the few things I am really proud to represent from the EMC portfolio.

I get it... "Free and friction-less, Free and friction-less, Free and friction-less" I hear the marketing terms. The reality is that enterprise customers aren't going to run this thing unsupported. It's free like a puppy is free. :)

So why is the software only more expensive than XtremIO? I can't imagine with the cost of the physical nodes is on top of that.


Could the VxRack Nutrino become an HPC monster.
