Re: Timeline for EOS HMC x86

Rob, I have actually quoted a solution for a client in which the primary
HMC is a 7063 and the secondary is a vHMC running on the p9 machine. It
assumes that only one site will go fully down, and even then the vHMC LPAR
will be configured to autostart so...

For Power based HMC's I believe most people will purchase a standalone
power server about the same size and horsepower as the x86 model. Sure, if
you have multiple Power systems you could configure each to be a HMC
console for the other but this seems to scare the bejeezes out of many.

I'm still wrapping my head around this. The vHMC was a blessing for mid to
big customers that already had a vm server farm. But now we are back to
"buy my hardware or else". It's not exactly easy to have a secondary Power
server available to run the vHMC for POWER and even then, I'm betting it
only runs on p8+ machines (due to endian-ness) so no chance of giving a p7
machine another life. And the final point. Unless using the physicial POWER
HMC, you get into the chicken and egg situation where you have to very
carefully configure the LPARs to autostart and not be dependant on
anything, otherwise a full blackout will mean you lose your vHMC...
IF the ASMI/FSP had a barebones LPAR management interface, like ESXi's
interface (You might be using vCenter to manage your server farm, but you
can still connect to each host and start a VM), I would go with vHMC for
POWER. As it is, I don't see the point.

Rob, this article outlines a version that will not run on x86.

What's the timeline for the End of Support for the x86 based HMC's?
One of my first concerns is when will there be the first firmware
release for Power 8, 9 (or above) which requires a level of HMC code
higher than that which will run on x86 based HMC's?
