Re: still seems flakey
So I don't know the context here fully but let me attempt to explain what might be going on here. So as you know VMware is a fiercely independent company within the DT umbrella, VMware technologies work great across many different X86 Vendors including Dell Server platform.
We do have solutions/products where we do leverage the power of both companies to offer a truly integrated offering however that's a different set of outcomes. i.e. buying a VSAN ReadyNode and VSAN is a reference architecture/build type outcome where you as a customer are responsible for integration and lifecycling of the system (yeah you may pay someone to do the initial stand-up but after that your on your own). Products on the other side of the spectrum such as VxRail /+ VCF are of the 'Buy' outcome and have been Engineered to a different set of standards, this is where we can leverage the power of both orgs to for example have an iPhoneEsq upgrade experience for the entire stack.
Some people still enjoy tinkering and having complete control of the stack and the reality is that you own the complexity and issue associated with that, regardless of the vendor.
