These nodes have half the RAM of the proposed AMS nodes, and (I just learned), have H310 raid controllers, which are apparently notorious for "extremely poor performance".

So, to follow up here:

• Pros: alleviates an additional burden on @mark while improving turn-around time in the event of hardware issues, and avoids potential PII issues with test data
• Cons: Has half the memory of the proposed AMS nodes, and very poor disk performance

As much as I'd like to avoid the pitfalls (for everyone) of the ams-based machines, aqs100[1-3] seem sufficiently problematic that we run the risk of failing at our primary objective (to create a test environment with similar performance characteristics to production). I think my preference would be to stick to plan A.

Indeed, @Eevans . Getting the nodes just for the sake of it doesn't seem prudent, especially since it would not allow us to synthesise production load no more than we are capable of doing so now.

reading "have role spare" and then "return to spare pool", doesn't that mean it's already in the spare pool?

Hey Daniel, I didn't know if there was paperwork between the "role spare" and the "spare pool" assignment :)

No, it doesn't. "role spare" is used for the time until they're returned to spares/shutdown (since that can take quite some time, especially in esams).

gotcha, thanks both

Adding ops-eqiad tag since now its pending onsite actions.

@Cmjohnson: Are these R720xd's able to be retrofitted with SFF SSDs without issue? Please advise.

If so, we'll need to order some Intel S3610 SSDs to place into these for their work with services (linked task T136340)

Sure, they can be retrofitted I have plenty of LFF/SFF adapters .....but are you sure we want to do that?....they're out of warranty and aqs1003.

Oh, these are LFF bay systems? (I didn't think the R720xd could retrofit SFF into LFF bays on the hot swap chassis.) At LFF, its only 12 bays correct?

My understanding is services wants these since they are powerful enough for their testing systems. Since it won't be live traffic, but a test bed, the lack of warranty is less of an issue.

If we can swap in SFF disks into these without an issue, I'll price out the options for SSDs on a procurement task.

Updated to my comment about the ssd's fitting for the aqs systems. I attached the ssd with the SFF adapter to the disk caddy for the R720XD and the ssds with that SFF will not work.
