Re: Consistency is king
Maybe I'm wrong but I recall VCE as a Convergence platform not a Hyper convergence platform. Not that I've had any interest in CI or HCI, just regular servers+SAN storage is good enough for me. Haven't even touched a blade server since 2011(yes I know blades are out of style now), nothing but DL38x (with 3PAR SAN) in the years since for my critical stuff. HCI sounds neat on paper, and can make some things simpler I'm sure.
My oldest active 3PAR is a 4-controller 7450(all flash), will enter it's 10th year of service in about 45 days, 0 software failures, and just 1 hardware failure(single SSD failed early this year, still had ~88% wear left on it). Still works fine, so no reason to retire it. Have 4 hour onsite hardware support from 3rd party.
Company I work at now has a vSAN(technically VxRail) for development stuff and am not impressed(perhaps not vSAN technology's fault, but the performance is terrible despite being all flash). I get tons of metrics out of it but no smoking gun. Fortunately(perhaps) it's been running bad for years and people are used to it. It will be retired soon.
