It depends on how active the DBs are. If you're talking about an SQL instance supporting a financial institution or a large retail chain, there's lots of work to be done. But if you're talking about a medium-sized consulting company, you can go a long time without touching it. But in a previous life I was at a large FI and they tend to be risk adverse so patching and active maintenance is important.

Citrix XenSever (and XCP-NG) are found in production environments. They're meant for clustering and all sorts of other goodness. DO compile a XenOrchestra instance from source. The features are amazing. Live Migration's fantastic, as it being able to dump the whole VM as a single file. XCP-NG + TrueNAS is a beautiful combo if you've got the resources to put it together.
I was thinking XCP-ng, but a lot of people say go proxmox...Coming from a vmware world, a lot of the features in XCP-ng would be nice, Eventually I'll have the hardware to have both in my homelab, but until then, will have to figure this out. Thanks!

I put this together in 2016, and spent about a little over $1000 total for two managed 20-port switches (D-link DGS-1510-20, not still available new except as remaining stock as best I can tell), each with 18 gigabit ports (16 copper, 2 fiber SFP) and 2 SFP+ 10 GBE (about $750 for both back then), plus a NIC for my server (2-port SFP+ Intel) and about $100 for SFP modules (cheaper now.) 100' fibers were cheaper then, but I bought them locally so I don't remember how much - probably about $50 for both of them

To do it the standard "everything goes back to 1 closet, and a single big managed switch" would have been probably $150+ and maybe another $60+ for a smaller 2nd spool just for the extra copper to do 10-12 runs under the house, plus a patch panel, plus a lot more wear and tear on me. A good 24+ port managed switch wouldn't have been much cheaper than one of the 16+uplinks, so I'm already at half the cost even before figuring out how to uplink the server properly (port bonding on 1GbE doesn't work all that well.)

It would have been quite a bit cheaper in late 2019, before supply chain shocks.

There are still cheaper options today, although not as many readily available: Microtik is really cheap for 10GbE: a 2-uplink model https://amzn.to/3oXnJ74 or https://amzn.to/3avkyeA for a 4-port 10GbE model (you can use the gigabit port as either a dedicated management port or a downlink on the same bridge) or https://amzn.to/2YDcwxX for an 8-port which would be a good backbone switch. These look interesting as well - https://amzn.to/3iT51tx for a cheaper uplink model

For fiber connections, you'll need something like this https://amzn.to/2YKGVKG for either end, or something like https://amzn.to/3iST8E5 but they only are good for lab. I thought they went to 10M but the longest I can find right now is 7.

10GbE copper switches are much more expensive, last I looked and on a cursory look on Amazon, but I may be missing something.

I use the 2-port version of this NIC: https://amzn.to/3awgf2q - there are cheaper ones, but the Intel X520 drivers are really stable. Unlike the switches, copper 10GbE NICs are often a little cheaper.
That's definitely going to cost a bit more here. I'm sure if I search hard, I could find great deals up here, but I find for a lot of hardware, Canadian prices are not on par with places in the US. But at least with what you've laid out, I have an idea of what to use. Microtik has come up several times as affordable (not here). For the most part, I can deal with 1GbE stuff, but once in a while, I could use faster when doing buildouts for clients... Also dealing with a dearth of wifi signals in the neighbourhood... so what I can take down I'd prefer to just to speed things up. Thanks! Now at least I know what to expect.
