@fgiunchedi yes in codfw we do have physical space and ports available also on the 10 GB switches

thanks @Papaul !

@Cmjohnson would there be enough space in eqiad to do the above? (i.e. 12x new swift backends installed in parallel with old hardware or we'll need to do it piecemeal?)

@fgiunchedi In eqiad it will be a little tight in rows A and C. I should
be able to accommodate 4 in each rack but will have to move a few
decom'd/spare cp servers out of each rack. Row D should not be a problem.
In fact with the expansion I can add 2 to row D2 and 2 row D7.

Ok thanks! If we can get say 50% of the new hw already in place with existing old hw that should be enough to get things started, we'll figure out the racking details.

@fgiunchedi

We have limited space in row A but could accommodate 3 10G servers,
row C8 could also add 3
Row D we will have 2 10G racks and could split them 3 and 3 (once the new switch stack is ready)

Also there is plenty of room for 1G servers in all 4 rows.

per irc

godog cmjohnson1: ok, I'd say then 3x per row 10G where possible and 1G otherwise
