Look on your existing drives in your cluster and see how much space the "account" and "container" directories are using (eg `du -sh /srv/node/*/{accounts,containers}`). Sum that across all the servers in your cluster, and you've got it. As a general rule of thumb (ie HUGE ASSUMPTIONS MADE HERE), account and container data is generally below 1% of the space used for objects. At least that's a starting point you can use before you have real data. As always, base decisions on data over recommendations. --John On Feb 17, 2014, at 7:41 PM, Stephen Wood <smwood4 at gmail.com> wrote: > I'm preparing to migrate our container servers to SSD hosts for better performance, but I'm unsure on how to calculate the space required on these new hosts.
