So 1GB RAM per OSD of Size 2TB(just re-iterating) is good enough?
Because I read somewhere 1GB RAM/OSD of Size 1TB is whats recommended

I usually like to go a little higher than 1GB per OSD personally. Given
what a box with 24 spinning disks costs, I'd be tempted to throw in 64G
of ram, but 32GB should do ok..

Hello,
We have boxes with 24 Drives, 2TB each and want to run one OSD

keeping in mind that OSD Rebalancing and failure/replication of
say 10-15TB data
