The current production phabricator machine is "iridium" on trusty.
Then we have "phab2001" in codfw on jessie, using the same role but obviously not in prod.
What we want is "phab1001" in eqiad, on jessie, to go along with phab2001.
There was an original plan to make phab2001 the prod machine and then reinstall iridium and rename it to phab1001 while prod traffic is not on it.
But since we can't just switch a single service over to codfw while others stay in eqiad yet (due to lack of per-service routing in VCL), the prod system has to stay in eqiad for the time being.
Checking the warranty expiration of iridium i see it is soon on 2017-03-23.
Given these things i suggest we get new hardware for eqiad, install it as "phab1001" with jessie, confirm the phabricator role works fine on jessie (T158434), then switch prod from iridium to phab1001, both being in eqiad, and finally decom/reclaim iridium as a spare and call the "rename" ticket T152129 resolved.
So this is for a physical machine that is similar to iridium., HW type: Dell PowerEdge R420, wmf4547
