I would not buy synology at an enterprise level. I would use a NetApp.
Also we use non-Cisco optics all the time, but keep just a few (genuine Cisco) around. So we’ll buy a pile of fluxlight optics and one Cisco for a set of switches. Load it with the cheap ones, but you can troubleshoot with the overly expensive Cisco sfp if needed.
I found Mint rather simple to install. That said, I am a techie. I am using several different distros in my house, but I wanted to live in Mint for a while to see how well a non-techie might fare. My reasoning was that since Ubuntu (Mint’s parent) is rather ubiquitous, there is more development and more attention paid to support and troubleshoot issues. So far, so good. Yes, being tech literate does help, but I think a non-techie could live with Linux. And over time, the environment will become more known like Windows is now.
