Re: No thanks
If you only know Storage Spaces...there are big spaces in your storage knowledge.
Ever try to do SMB from a Linux server? Did you notice that SAMBA still sucks? File protocols are complicated beasts and Open Sores software is always going to be behind whatever the creators are trying to emulate from the private software world.
Using Nutanix for storage, however, is sort of like using your snowmobile to pull your boat. In a corner case it might actually make sense but is not really a best of breed solution. Scaling into large capacity solutions gets weird fast.
