Adding RAM

[marius1]

I plan to install VMware ESXi on an HP server and to start using it to host VMs.

If I have the option to add RAM later, can I add RAM (after powering down host and guests) without re-installing VMware ESXi?

Can I presume that VMware ESXi is smart enough to detect the increase of the RAM and use it?

Is there any action I must plan to make ESXi detect and use the additional RAM?

Season's greetings and regards

No problems with adding RAM later. Just shutdown the host, add the RAM and power it on again. That's it.

I just had an issue once with a DL380 G5 where the host did not recognize the newly added memory. However this was related with an old firmware version and I had to update the firmware on the host.

With G6 and up make sure you have the same amount of RAM for each CPU!

just like any modern operating system, the newly hardware changes can be detected without fresh installation of the OS.
