Maestro and LOM

Question: What is the added value of LOM cards in Quantum appliances when used with Orchestrator ?

It's purpose remains as for normal appliances but doesn't directly benefit the Orchestrator itself.

For this and other reasons having out-of-band console server connectivity is recommended for Maestro deployments.

So in which situations would Maestro deployments benefit from LOM on the used appliances ?

Perhaps some emergency situations where remote console access is unavailable (i.e. no console server) 

So hypothetically this might be things like:

* SGM boot issues 
* SGM rebuild scenarios
* SGM monitoring

Again, console access is usually recommended for Maestro/Scalable Platform.

Last month one of our  customer had a problem with freezing appliances in a Maestro setup.

A reboot was only possible with power off via LOM Port and the only access to the appliance was too the LOM port.

This is a very useful thing for a LOM Port on the appliance.

This makes it perfectly clear why a LOM Port on the appliance makes sense - thank you !

Additionally to  things  that were already said:

I am a fan of installing major versions not via CPUSE. I prefer making a fresh install via LOM ISO mount.
Reason: When upgrading  via  CPUSE the  revert image which is  used when fcd an appliance will not be upgraded.
So in case of you need to  fcd and you did the latest major upgrade via CPUSE  you always have to upgrade the major version  and  installing  the  latest JHF.
This takes  time  and time can  be a problem in specific scenarios.

So  for imaging an appliance there are two options: USB  or LOM.
If  the appliances are in  a  remote  datacenter USB can be a challenge.
