Server Sizing Concept
Determine your server configuration (components and the number of units) depending on
1) required hard disk capacity and 2) video data quantity per second.
1) Required hard disk capacity: Consider the required hard disk capacity depending
with regard to continuous recording with fixed frame
rate, resolution, and quantity. For reference, you should
use multiple servers if the required hard disk capacity is
1.5 TB to 2 TB per server.
2) Video data quantity per second: If the video data quantity per second per server
exceeds values shown below, you should use multiple
servers or review the recording conditions.
Approximate Video Data Quantity for 1 Second
The recording performance of the VK-64/VK-16 v1.3 is as follows.
For dedicated Storage Server: Maximum amount of recorded data per server = 5.5
MB/sec or less
(VGA: 110 fps, QVGA: 360 fps)
For Storage and Playback Server: Maximum amount of recorded data per server = 3
MB/sec or less
(VGA: 60 fps, QVGA: 200 fps)
Required Hard Disk Capacity
The VK-64/VK-16 receives each image from a Camera Server as a JPEG image. The size
of the images varies depending on the configuration of the Camera Server (the settings for
Quality and Resolution) and the complexity of the actual image.
Every installation of VK-64/VK-16 is different (due to different
usage requirements and different hardware specifications) and
the figures provided in this section are an indication only.
Note
The write performance may be lower than mentioned above
depending on the RAID card used.
