Why running multiple servers?

Hey just noticed your reply to another user and I saw something you said that many others here have also do and I wanted some insight. You mentioned that you run 2 separate servers in you home at the same time. What advantage or reason is that? Thanks

Mod-Edit: I moved this in a separate conversation. Please try to avoid going completely off topic in ongoing discussions (even if there wasn’t much meat to the bone in that other thread).
This post was in response to a post from @CWallace

some run separate servers for testing, or to separate content to different physical hardware.

like perhaps a dedicated live tv server with a tuner card, or a music only server to help keep separate long library rescans.

with the UNO interface, its easy to ‘pin’ libraries you want and it doesn’t matter which server they are on.

Well, I am guilty here, too.
One of my servers is completely for DVR business.
Output on this should not mix with edited material which goes into a number of libaries on the “family entertainment” server.
plus backup processes

The All-in-one idea (just use libraries for everything) does not fit well my needs.
The day I decide to turn my back to Plex DVR service is the day that I switch off the second server.

I run 4 active servers, one DVR server, have a conversion server and a test server


The active servers spreading the transcoding load
 (wish it was more like a cluster)

Early, early on in the Plex DVR run I had the DVR delete some of my Blu-Ray/DVD content in another library. Didn’t like that happening so I moved the DVR to a separate machine. That server now holds Plex to serve content and Channels DVR to record it. Works great.

Full disclosure, I have a THIRD Plex server that I use for testing. It’s REALLY handy if I’m testing stuff like how the Scanning Agents work without messing up the other two machines. It’s a totally disposable install in that if something goes radically wrong I can erase everything and start over. It’s not even turned on most of the time.

They are all old Macs with the newest one being a MacMini 2014.

Sorry about that. Was trying to let the OP vent and then try to detour it into something constructive. I’m not a big fan of internet hate in any forum but understand that people are frustrated and need to vent.

But it is so much fun to watch people have melt downs on the internet. I sometimes wish the mods would just let things go for longer than they do. But, in some cases, at my age having so much fun could endanger my health.

But back on the topic in general:
I used to run two Plex servers that I kept in sync to assure that should something go wrong I would have a fallback server. But, since I switched to Emby for most of my use, I now only run one Plex server but I do have two Emby servers for the same reason I had two Plex servers.

And of course the other reason I ran two servers was because I could. That also applies to Emby.
