I never use less than 3 chars and I try to never use more than ~8 chars. - currently for the dedicated servers that I rent at "Hetzner.de" I use just "he1", "he2", "he3", etc... . I don't have a high turnaround (e.g. I don't have he1 anymore but he2 runs since many years) and they're all located in Germany (I had one hosted in Helsinki until a few days ago but the connectivity was often really bad whenever Hetzner was doing changes to their network), so after a few hours/days I start remembering instinctively what runs on the latest server that I have set up. - for the notebooks/servers I have at home I use from time to time a nickname. E.g. my old "Lenovo Carbon" laptop is just "carbon", but a NAS is called "story" (storage server which has only 4 disks -> fantasy-diminutive of "storage" was for me "story"), a server which has a Ryzen 5950x CPU with 3 big fans which used to make a "woooossshh"-sound whenever it spun them up is called "windy" (I then disabled the "boost" feature of the CPU because the noise of the air was annoying and it was anyway getting too warm in the flat, but the name stuck), a big tower-PC is "biggo", etc... . - for VMs I always use the prefix "vm" followed by some chars which describe what the VM is supposed to host, followed by a number. E.g. I have currently "vmdbcommon6" (to host a general-purpose database, 6th reinstallation), "vmbot4" to run my web-crawler, "vmweb1" to host the website, etc.... I NEVER refer to Linux distributions names nor software names as it happened many times in the past that I wanted/had to switch. So, nothing too clever in my case... .
