Getting ON BOARD
POWER9 brings changes to the Hardware Management Console
he Hardware Management Console (HMC) is evolving, and you'll need to
adapt. IBM is moving away from the traditional x86-based hardware appliances
and will only be selling POWER* processor-based 7063-CR1 HMC appliances
going forward. One reason for the change is that some clients have concerns about
running Lenovo hardware in their data centers, and as the supply of these appliances
dwindles, we'll no longer be able to order them. Others have always questioned why
we were managing IBM Power Systems* hardware with x86 servers in the first place.

According to roadmaps I've seen,
the 9.1.910 and 9.1.920 releases
will be available sometime this year
for both platforms. However, with
the 9.2.930 release (expected in
2019), the code will be compiled
for POWER only-not x86. As end
of marketing and hardware support
takes place, it will be time to
migrate your data center away from
x86 HMCs entirely.
Currently, you can choose from
four different options to run your
HMC. Of course, there's the traditional x86-based HMC appliance
that you've been using since
the IBM POWER4 days. Alternatively, you can run a virtualized
HMC (vHMC) image in either the
VMware, KVM or Xen hypervisors
on your own x86 hardware. Or you
can run an HMC appliance that's
based on the POWER processor.
Finally, you can run a vHMC image
in an LPAR on POWER hardware.
As with any other workload, the
HMC code will be capable of utilizing the strengths of the POWER
threads, greater memory bandwidth and superior performance.
