Description

mw2061 to mw2074 are API app servers which are out of warranty since 2014-06-14.

Instead of reimaging to jessie we should rather remove them, codfw currently has a higher number of API servers compared to eqiad anyway (68 in codfw, 50 in eqiad)

We can remove these, but we'd probably need some more servers to compensate the loss of computing power (eqiad servers are now newer and more powerful).

Yes, the batch we bought in May was supposed to replace these. However, we have budget in this new FY to expand capacity.

@Joe can we proceed with the decom or would it be better to wait for the replacements?

MoritzMuehlenhoff added a comment.Sep 9 2016, 12:37 PM

We discussed that on IRC, I'll decom these.

mw2061-mw2074 have been removed from puppet, Icinga, conftool and Salt and were powered down.

Yes, these should be decommissioned as they're very old.
