System Design Concept
Server Sizing Concept
Determine your server configuration (components and the number of units) depending on
1) required hard disk capacity and 2) video data volume per second.
1) Required hard disk capacity: Consider the required hard disk capacity based on
continuous recording with fixed frame rate, resolution,
and quantity.
2) Video data volume per second: If the video data volume per second by server exceeds
values shown below, you should consider multiple
servers or review the recording conditions.
Approximate Video Data Volume per Second
The recording performance of VK-64/VK-16 v2.0 is as follows.
For dedicated Storage Server: Maximum amount of recorded data per server = 5.5
MB/sec or less (when using SCSI, SAS disk)
For Storage and Playback Server: Maximum amount of recorded data per server = 3
MB/sec or less
VGA QVGA
JPEG 60 fps 200 fps
MPEG-4 Total 24Mbit/sec.
VGA QVGA
JPEG 110 fps 360 fps
MPEG-4 Total 44Mbit/sec.
Required Hard Disk Capacity
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 operation environment of VK-64/VK-16 is different (due
to different requirements and different hardware
specifications) and the figures provided below are just for the
reference.
Data volume per drive should be less than 2TB.

Data-writing performance may be reduced than the approximate
values given above depending on the hard disk or the RAID card
in the PC.
