How do you name your servers?

I have heard that while silly,.. people using Disney Characters for names..
I have also heard that for security reasons, you should not name them AD1 or ExchangeTwo... But that was 'heard' and not verified.
That's commonly said. But it is, wait for it, security through obscurity. It's true that writing "super critical data that we just protect at all costs" on a server name is probably dumb, announcing that something is a web server on Linux or AD on Windows probably does nothing. Anyone on the network already knows what services those things are offering. Trying to obfuscate that makes it harder for the people on the network but an attacker likely would not notice.

Naming trends like that only work well if you have very few servers with low turnover. Otherwise you are getting into really obscure names that defeat the purpose.

That's great if you can remember that there are more ships than NCC-1701A -E.. I'd need the History of StarFleet to keep up with them.

Very true - this wasn't in use after they had around 15-20 servers. then they moved to something like Scott's or my naming convention.

Of course you could have the "Mark 1" and then the "Mark 2". LOL

Don't even get me started on that crap!

Here is an issue that we ran into with the "Star Trek" style names (ours were cities.)
When we repurposes a server, say from being an IIS App server to being an Email server we would not rename it from Salzburg to Innsbruck as that would be weird, right? And you would run out of names quickly. The physical hardware was known as Salzburg and Salzburg it would stay throughout its life. Sensible. Sort of.
But now if to-lnx-db1, a database server, gets repurposed into an email server, it gets renamed to to-lnx-ex1 or whatever. Way more useful for people who need to access it based on what it "does" rather than based on "which physical hardware it is on."
As we move to virtual and way moreso to cloud, conventions like Austrian cities can't work. You make and destroy so much more quickly and names don't hang around. With cloud, how do you autoprovision city names or Star Trek ships? Do you run a naming server that stores thousands of city or ship names and keeps track of when they have been handed out and removes them from circulation once they have been handed out? You could eat through hundreds of names per day if you are on cloud.

LOL - I didn't say it was a good long term plan - he simply asked what people were doing

I have about 25 and go with a basic two letter followed by a two digit number. So for domain controllers, it is DC01, DC02, etc. For File/Print, it is FP01, FP02. I also have boxes that are "IT only"; things like spiceworks, prtg, WDS/MDT, Veeam, etc and each of those servers gets IT01, IT02, IT03, etc.
-
We name ours based on Business unit, geographic location, then function and then staring with 01 and going up for each of the same function at the same location.
so a SQL server in LA, for the fake business united called Sam's Mart (okay just copying Sam's club/walmart for this example) might be
SMLA-SQL01

All of my desktops/laptops are transformer names. My desktop is Megatron, my laptop is Ironhide, and my other laptop is Bonecrusher.
Servers are just what their purpose is and if there is more than one, I just add a number after. So ZeroTier, Drupal, FreePBX, etc.

At home my computers use Star Wars planets as names.
At work... spoilers

I used to give them girl's names but now I just name them after their role, plus a number.
So
SQL01, SQL02, EXCH01, ESXCH02, DC01, DC02, FILESERV01, SHAREPT01 etc etcIn the age of virualisation and rapid deployment of new servers, this seems to be only practical approach in my opinion.

Cute names become counter productive with more than a handful.
I once named everything on a network after characters from The 5th Element.
Everything is named based on client - purpose - sequence
Example: ntgdc01

Yeah, I agree. When you had physical servers that lasted a decade and only a few of them saying "Betty is down", or "The Enterprise has been infected with malware" or "Vienna is running slow today" was effective because we treated each one like a person and everyone dealt with just a few of them. It made sense in smaller environments. I still remember the roles of our two biggest Windows NT 4 boxes from the 1990s. They each made it ten years and were named Vienna and Salzburg. I can still tell you the memory configs on them, what apps they ran, their RAID configs, their processors, and their full histories. There were our babies, so naming them as such made sense.
But now that we create and destroy VMs every day and have tons and tons more of them that would just not work like it used to. It used to take months or years to decommission a physical box. Now we turn off a VM in seconds.
