1 The lower number of cameras per storage set, the higher achievable throughput. This is due to
a lower total data rate required to record to each storage device.
2 High bit rate cameras (e.g. megapixel) should be spread across storage sets for load
balancing.

Avoid assigning Virtual Disks from the same Disk Group to different storage sets. If this is done, there is a
high probability that continuous disk thrashing will cause the storage device to lock up and cause
undesirable results to the NVR.

You need to have enough storage space to fulfil your video recording requirements without data
being culled unnecessarily. To ensure you do have enough storage it is important to carefully
calculate your storage requirements.
