Notes

1. QSAN RAID Calculator can estimate the space utilization of various disk configurations and RAID levels on QSAN NAS, SAN and FAS series. The results from QSAN RAID Calculator should be used as a reference only. QSAN makes no guarantees for results generated with this tool. The actual capacity used is subject to the storage control panel interface.

2. If you are planning "spare" for different models that will limit the capacity of a single storage space, you still need to go through qualified QSAN Sales or technical support confirmation, or contact QSAN customer service for more assistance.
