Re: Roll your own
The cost of these HCI "appliances" from Dell, HPE, Cisco and Nutanix are eye watering.
Plus complexities of a new interface and managment stack coupled with vendor lock in make it seem to me like a terrible idea.
X86 tin with a common as muck OS that has virtual SAN, SDN and VMs sounds like a much cheaper proposition to me. Not sure why ElReg keep banging on about HCI being appliance based. VMWare, Microsoft and the OSS community all have their own HCI take built into the tools we all know. Coupled with cheap and entirely compatible X86 tin and it's a no brainer to me.
