On the racking proposal, I'd say that this could potentially be revised to incorporate row E (and possibly F) into our planning & thinking. Not sure if that makes sense here, but I figured it's something that @Gehel and team may not be aware of yet :)

Your racking info is very detailed, but Faidon wanted to ensure you were aware of this (as you filled out the racking info on this request). Can you review and revise the racking details section of this as needed knowing about rows E/F, or if no changes needed just reassign to @Jclark-ctr, thanks!

Hi @RKemper - just following up on this. With rows E and F coming online in a couple weeks (and rows A thru D being very tight on space), would it be possible if we balanced some of these servers across rows E and F as well? Thanks, Willy

@RobH @wiki_willy Yes, rebalancing across E and F is fine by us. Would you like us to recompute the racking details or is it easier if we let you guys figure it out?

Thanks @RKemper. If theres's a general criteria of no more than X number of servers spread across X number of rows, just let us know and we'll try to make it work with some of the space constraints that we have in the old cage. Thanks!

@wiki_willy @Jclark-ctr

Since we're adding E and F to our list of allowable rows, we'll want to fill those new rows in as much as possible to minimize the size discrepancy between A-D vs E-F. And similarly, we don't want to shuffle any of the old hosts around, so it makes sense for all of the 14 new hosts to be split between E and F. That will optimally minimize the variance between rows. Ideally there's 7 slots each in E and 7 in F, but if it's 6 in one of E/F and 8 in the other that's fine. So this would be great if possible:

Row A (9 servers): elastic10(53|54|68|69|70|71|72|73|84)
Row B (10 servers): elastic10(55|56|74|75|76|77|78|79|85|86)
Row C (9 servers): elastic10(57|58|59|80|81|82|83|87|88)
Row D (8 servers): elastic10(60|61|62|63|64|65|66|67)
Row E (7 servers): [too lazy to enumerate]
Row F (7 servers): [too lazy to enumerate]

TLDR: Hopefully it's easiest for you guys to just shove 7 in row E and 7 in row F, because that's easiest for us if we're adding these new rows anyway. There's no reason to stick any new hosts in rows A-D if we're going to have some/any hosts in rows E-F, because that would lead to a big discrepancy between row sizes.

Thanks @RKemper, I appreciate it. I've gone ahead and updated the racking details in the task description to reflect that. Thanks, Willy
