Re: HMC x86 support

TOTALLY disagree. VHMCs are awesome!!!!

Why do you not like vHMCs?

VHMC does:

-Boot up in 10% of the time of a physical HMC.
-Takes *ZERO footprint in the data center.
-Costs 1/3 of the physical HMC
-Updates put on vHMC are incredibly faster than Physical HMC as they don't spend 10 minutes during EVERY update waiting for the physical server to boot up.
-With VMWare you have automatic remote console to the thing rock solid.
-You can trivially and quickly clone it to another X86 stack for redundancy as well.

POWER Based HMC:

-is twice the size of an X86 HMC (2U) and infinitely bigger than vHMC
-four times more noise
-double the power requirement (and thus cooling)
-triple the cost of vHMC

Sure it has IPMI remote port on there, but is it supported? IBM told us NEVER to use the remote console on X86 HMCs as it was not supported so I'm guessing this will be the same.

POWER Based vHMC is a non-starter in virtually all shops. They don't have enough quantity of Power Systems.

And don't get me started on VPM!

Larry,

The 7063-CR1 HMC (POWER based) will still be available and is similar cost to the 7042 x86 HMCs. After some trials of the virtual HMCs I’m recommending physical HMCs to customers. The virtuals do make a good backup/redundant HMC for those who want it.

From what I have seen in other places, yes. This is going to be a big

problem I think for smaller shops. The POWER based HMC is a great idea
and I like it, HOWEVER you cannot use it to manage the server it runs
on. As a consequence you need a minimum of TWO Power Systems. And should
they both be down at once you are officially out of business at that
point. As a consequence you pretty much must abandon virtual HMC and go
to a POWER Based 7063 HMC. In the small shops that is A LOT of cost to
add to support virtualization.

I am working on getting better clarification on this because I do not
like it.

IBM has announced the end of software upgrades for x86 based HMC’s (see below). Does anyone know if this includes the virtual HMC running on VMware? I suspect that they are included since they run the same code base as the hardware appliances but a case could be made since they call out the 7042 hardware models.



Major update support for x86-based (7042) HMC hardware appliances will end in 2018. From 2019, HMC updates will only support Power®-based (7063) HMC appliances. However, software fix support for existing in-support releases for the x86-based HMC appliance will remain unchanged. See the IBM POWER® code matrix website for the lifecycle of releases for the hardware appliance.
