Agreed. Though I'd also like to ask about node and OSD counts
(aggregate/largest).
We could simplify this by collapsing total/largest if they only have one
cluster - perhaps we can only show the "largest" column if >=2?
The capacity/node/disk count figures always look great in the survey
results, and will also allow us to have some comparison relative to the
last year's.

I'd still like to ask about the data protection schemes, perhaps for the
one with the most data?
Alternatively, we could ask them for net vs gross vs used capacity and
try to compute that from that, but I'm guessing it's easier to ask them
for the top 3 schemes they use.
The OSD FileStore/BlueStore trends would also be quite useful at this
stage, again mainly for comparison purposes. I realize we'll eventually
get that from telemetry, but we're not quite there yet.

Yes.

Do we still have a chance to run this survey in 2019? End-of-year
survey?

Lars
