Hi all,

We have a system here with 240million files which are in total 40TB, the average filesize is around 174kb.

Now this eats 90TB from the customers 3-node cluster. So instead of 33% overhead we have around 127% overhead...

From all what I can find can we expect some addtional overhead with this relatively small blocksize, but 50TB is a bit huge...

Can anybody shine a light on this? (In the past we had this fantastic Isilon capacity calculator, but the URL doesn't work anymore...)

By the way: the cluster is running OneFS 7.1 code.

Thanks!

Jan-Pieter
