      Honestly, I'm still trying to debate if RAID 5 is worth it vs RAID 1 with SSD's in mind.

      If you don't need the capacity, then no, stick with RAID 1.

        I've only had to deal with RAID 5 on my old server, and I nuked it and never looked back, went with RAID 10 on spinning rust.

        Yes, but since none of the RAID 5 issues from that era exist with SSDs, that doesn't apply here.

          You can also install the GUI on the server and have local management tools. Obviously managing purely remotely is better. But as this is a desktop anyway, local management tools are not out of the question and you can switch later once you are comfortable with it. There is no lock in to your GUI or tools choices like with Hyper-V.

          "Obviously"

          Hey do you consider cockpit a GUI?

          Yes, do you consider it local?

          I don't consider it a GUI like the traditional GUI that sits on the physical box, aka CInnamon or Windows.

            Scott how will the migration from XenServer to KVM go?

                I've not done it. We rarely migrate, we build new. We are a DevOps shop, there is no reason to ever migrate in the modern DevOps world.

                  No I am just wondering if someone said "I installed the GUI for FEdora server" if you would think they were talking about cockpit.

                    Most people mean the desktop GUI, so that you can hook up a monitor. Cockpit cant be used on a local monitor without another GUI existing that is local. But that's not what you asked me.

                      I'm doing my research to get on KVM. I might go with Ubuntu for my home use. I'm still semi-noob.

                        Avoid using Ubuntu. It's unnecessarily complex. Stick with Fedora, keep things simple.

                          You start playing with Ubuntu, and the next thing you know you get sucked into thinking two year old LTS releases are acceptable to deploy in production.

                            The one place that Ubuntu really rocks is if you are builing an LXC/LXD host.

                              Would you say same thing if some uses CentOS since it’s pretty much a LTS compared to using Fedora?

                                Yes, but there is less confusion around it due to the greater education and professional nature of the community. But it is exactly the same and why I've been talking so heavily about why it is time to abandon both.

                                  Scott I think many of us have it implanted in our head with spinning rust to continue to use RAID 10 as it felt the most safe and easy to scale 🙂

                                  Honestly, I'm still trying to debate if RAID 5 is worth it vs RAID 1 with SSD's in mind. It's an extra cost, what benefit does it bring? I've only had to deal with RAID 5 on my old server, and I nuked it and never looked back, went with RAID 10 on spinning rust.

                                  The question is - why did you nuke the RAID 5? Why did you move to RAID 10 instead of RAID 6? These questions are what can easily lead you to using RAID 5 on SSD instead of RAID 10.

                                          For the 100th time, yes. I feel like I answer this almost every day.
