title: How to calculate the maximum total data size for a Minio cluster?
body: <p>For a Minio cluster of 4 nodes with erasure code enabled and each node having 4 x 1TB drives (total of 16 TB disk size):</p>
  <ul>
  <li>what is the maximum size of data I can upload assuming that I have 8 data and 8 parity disks?</li>
  </ul>
  <p>When I read the documentation of Minio, I understand that every object is replicated across all nodes and disks. We can upload 2 TB data for each node (other 2 TB being parity). And if all of the objects are replicated on all disks then other nodes will also store the same objects. Then I can only store 2 TB of data with 16 TB of available disk size. Is that correct?</p>
  <p>Note: I know that I can increase the data size by decreasing the number of parity disks. I ask for the specific case of half data half parity disks.</p>
