282 VideoEdge NVR 4.4 Installation and User Manual

• Storage Set 1 = 16 CAMs record to first set of drive(s)

• Storage Set 2 = 7 CAMs record to

second set of drive(s)

• Storage Set 3 = 7 CAMs record to third set of drive(s)

Note

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.

Caution

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.

Calculating Storage Requirements

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.
