I'd like 16GB ram, 16 cores if we have a spare laying around that meets those specs. This is lower powered than neodymium; my gut feel is that this will be enough as long as we're not running other things over there e.g. puppetmaster.

So we don't have any systems that are spare and have that core count without also having an insane amount of storage. We have the spares listed on the tab 'CODFW Spare Servers' on this google sheet.
@ArielGlenn: 16 cores is a LOT of cores, does that take into account hyperthreading counting as cores? neodymium has dual intel xeon E5-2440. Link to Intel Site Info 2.4GHz and 6 cores per cpu.
So we've moved to less cores and higher clock speeds on the misc. specifications. So the spare systems I have available in codfw (that have dual cpu):
| Asset Tag | Hostname | Warranty Expiry | Rack | Model | CPU | CPU GHz | CPU Core Count | Memory | Disks |
| WMF5851 | 2016-01-13 | A5 | Dell PowerEdge R420 | Intel® Xeon® Processor E5-2440 | 3.00 | 6 | 32GB | Dual 500GB | |
| WMF5849 | rbf2001 | 2016-01-13 | A5 | Dell PowerEdge R420 | Intel® Xeon® Processor E5-2440 | 3.00 | 6 | 32GB | Dual 500GB |
| WMF6378 | 2018-12-07 | A5 | Dell PowerEdge R430 | Intel® Xeon® Processor E5-2623 v3 | 3.00 | 4 | 32GB | Quad 4TB | |
| WMF6380 | 2018-12-07 | B5 | Dell PowerEdge R430 | Intel® Xeon® Processor E5-2623 v3 | 3.00 | 4 | 32GB | Quad 4TB | |
| WMF6381 | 2018-12-07 | C5 | Dell PowerEdge R430 | Intel® Xeon® Processor E5-2623 v3 | 3.00 | 4 | 32GB | Quad 4TB | |
| WMF6382 | 2018-12-07 | C5 | Dell PowerEdge R430 | Intel® Xeon® Processor E5-2623 v3 | 3.00 | 4 | 32GB | Quad 4TB | |
| WMF6384 | 2018-12-07 | D5 | Dell PowerEdge R430 | Intel® Xeon® Processor E5-2623 v3 | 3.00 | 4 | 32GB | Quad 4TB | |
So I'd like to use either WMF5851 or WMF5849, since they have a total presenting cores (including hyperthreading similar to neodymium) of 12 actual and 24 ht-total cores. The use of the 4 * 4TB seems overkill for salt (but they are overkill no matter what, sata disks are cheap.) If we need this salt-master to eventually/poentially do other things in codfw, then one of the newer misc systems may be best.
@ArielGlenn: Please provide feedback? I'm assigning back to you for input. Once you have done so, this can likely get escalated to @mark for his approval and then back to me (@RobH) for implementation.
Thanks!

You're right, I checked facter and forgot about hyperthreading which is enabled over there on neodymium. So we could go 2 6-cores and be fine. WMF5851 seems good to me, let's do it!

I'm assigning this to you for your approval of spare system allocation to a salt-master in codfw.
The system allocated is one of our older spares in codfw (chosen due to the low storage requirements of the salt-master) WMF5851.
The details of this system and the alternatives are listed in this tasks history.
Please review and approve/deny/question/clarify the allocation of WMF5851 and assign back to me.
Thanks!

@RobH the HW warranty expiration date on this system is 2016-01-13. Is it okay to allocate this system for that purpose?

@Papaul: Not yet. I have this assigned to @mark for his review. We shouldn't assign spares (in non emergency situations) without clearing it with him.
In regards to it being out of warranty, that isn't enough reason to cease using it. In the instance of a salt-master, out of warranty is likely a non-issue. (We can spin up multiple masters and replace them when needed.) I don't make the final call on that though, Mark does.

This has been approved, resolving the request task. Task T125752 has been created for the setup and deployment of the server and assorted services.
