@nprofile1q... @nprofile1q... JFC that makes my setup look tiny... And I couldn't even fill my single 42U without a good amount of padding even if I consolidated all my kit, unless I somehow racked all my not-rackmount retro stuff too.
Here I have ~14U of various machines (if it was U-shaped to rack it, about 6 of those are "hypothetical" as the equipment is currently the wrong form factor for rack-mount) and even my "big rack" elsewhere with the big server, DAS, and tape array is still only 12U, patch panel and UPS included...
Though going bigger probably isn't the smartest idea unless I contract with the IX downtown for colo space, because I'm not sure my AC could keep up with the power draw of truly big iron... (The rack where all the horsepower lives is in a basement elsewhere, so doesn't really need AC even at the height of summer. Here in [redacted] I occasionally have to open the window in the middle of winter, and haven't had to turn the heat on in years, with a much smaller quantity of compute...)
