@jaredbusch said in Food for thought: Fixing an over-engineered environment:
I never use IPMI.
I've been underwhelmed with it. If you're curious, this is the motherboard that's on all of these servers:
What doesn't it give you that you want?
I might have to re-evaluate it. I've only used the IPMI View java app to use the virtual KVM console. I'm looking its web portal now, and looks pretty good. I would like a way to see RAID health status and configuration, but perhaps that's not a reasonable want.
Aww - yeah I have no idea if that's a reasonable want or not. I've always just used a vendor supplied app inside Windows to see the status of the RAID controller. Of course with virtualization, I haven't dug into how that works, connecting directly to the hardware, I assume via some something in the hypervisor, etc.
Yes, it's the driver on the hardware that needs to handle that.

Break this out so we can talk about it please.

There you go.

Can you break it down more for me? Specifically in a hypervisor setup.

Hypervisor doesn't really change anything. It's all the same.
You have a driver taht talks to your storage, this is always the case regardless of the kind of storage, hardware RAID is just one type. That driver is what gets storage healthy information from the hardware. From the RAID card in this example. That drive can then be queried by end user tools that can report to humans the status of the hardware.
hpacucli in the HPE world is this tool. It talks to the driver and allows you to get status, make changes and so forth.

So what, you'd get a CLI output from that command (obviously - cli is in the name) when SSH'ed/Powershell'ed into Hyper-V? OK that works.

If using a CLI tool, yes.

In the case of Dell or HP the new DRAC and iLO can do the RAID monitoring as well.

Only if using their hardware RAID, which is part of they key. In something like SuperMicro with IPMI, SM doesn't have RAID cards themselves.

Correct

Has nothing to do with new iDRAC or iLO. This has been a native function of those for years.

You cannot monitor Hardware RAID prior to DRAC 7 with DRAC... so that's not new to you?

iLO at least has done it since.... I can't remember when. A very long time. DRAC I have no idea.

@scottalanmiller said in How Does Hardware RAID Monitoring Work:
emember when. A very long time. DRAC I have no
Yes iLO I can understand but Dell was way behind...

That use to be true a lot. They seem to be catching up a lot more the last several years.

You made me go look at an old system i have out there with iDrac 6. You are correct.
That is what I get for not checking first. I did say I use OMSA for my daily driver, and that does.

But you are also correct on the fact that OMSA does that anyway so I reviewed the other post for context .

Pretty limited options for hardware monitoring of hardware RAID. Almost always done via software, somewhere.
