Power 740 and HMC

Power 740 and HMC


Recently I got a Power 740 from company. Actually three 740. :)
I am not a AIX or Power guy. My world are mainframes. But I like to learn more about other platforms. That's my case.
My hardware is running Linux and AIX 7.1 (the last one, limited, since I have no drivers to my ethernet adapter). I am only able to boot one operating system. I have followed some forums and I know about HMC and LPARs, I have a version HMC running in KVM, but seems this version is not enough to 740 hardware.
Could anyone share a compatible version of HMC to 740 series?

Thank you
