Over the last few months I have migrated servers twice. I went from my aging x346 to a HP DL-585g1 and then I have moved to a HP Microserver (HP Micro G7 N36L).
It was strange moving from a 2RU, then to a 4RU and then to a small form factor server. I went from dual 3.0ghz Xeons (4GB of RAM), to quad dual core 2.6 opterons (32GB of RAM) to a dual core 1.2ghz amd cpu (4GB of RAM).
Moving all my data across has become quite painful (downgrading from 7.2TB to 5.4TB is never an easy process). The other services were relatively straight forward.
However, I’m sure the environment is thanking me in its own special way.
