Solaris on SPARC had the ability to dynamically add or remove RAM as I understand it. I believe IBM AIX (+ POWER maybe?) can do this too. Modern Linux kernels

Modern Linux kernels will let you hot-add memory but won't let you hot remove it.
- scurvy 10y agoYep, CPU's too. On the E4500's the CPU's and memory were on the same boards. You could remove the board after sending the right ASR commands. Then again, you were constantly swapping boards to find the ones not affected by EDP (ecache data parity) errors.
