<div>Hi</div>

<div>Just want to validate my estimation for a C* cluster which should have around 3
TB of usable storage.</div>

<div>Assuming a RF of 3 and SizeTiered&nbsp;Compaction Strategy.</div>

<div>Is it correct, that SizeTiered&nbsp;Compaction Strategy needs (in the worst
case) 50% free disc space during compaction?</div>

<div>&nbsp;</div>

<div>So this would then result in a cluster of 3TB x 3 x 2 == 18 TB of raw storage?</div>

<div>&nbsp;</div>

<div>Thanks and Regards</div>
