Meanwhile, Windows requires you to buy a new license if you change your mouse.
Did anyone else notice that in their stock photo they’re trying to put the DIMM into the socket backwards?
I don’t understand how this is an advantage. Yes, you can swap RAM with the system powered up, but what happens to the information in the module that was removed? Is the OS doing some kind of RAID-like memory allocation? The article wasn’t clear on how this would actually work.
Apparently, there’s some coordination mechanism, where you tell the OS that you want to remove a certain memory stick, so it moves all the memory onto other RAM sticks (or uses paging to move it to your hard drive). Only then would you actually physically unplug the memory stick.
See, for example: https://docs.kernel.org/admin-guide/mm/memory-hotplug.html
(Mind that this is kernel documentation. If you actually want to do this, there’s probably some CLI program to make it easier.)
USB devices are also hotpluggable, but that doesn’t mean that the data stays in the system if you just pull out the HDD.
I remember the ‘good old days’ of Sun Fire 10k and similar servers. You could replace entire boards of CPU and RAM and the server would keep on trucking.
Excellent! Hot swap all the things!!!
