Canon Vb-C60 Network Video Recorder VK-64/VK-16 Administrator's Manual - Page 34

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. Note z 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. z Data volume per drive should be less than 2TB. Approximate Video Data Volume per Second The recording performance of VK-64/VK-16 v2.2 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) JPEG MPEG-4 VGA QVGA 110 fps 360 fps Total 44Mbit/sec. • For Storage and Playback Server: Maximum amount of recorded data per server = 3 MB/sec or less JPEG MPEG-4 VGA QVGA 60 fps 200 fps Total 24Mbit/sec. Note Data-writing performance may be reduced than the approximate values given above depending on the hard disk or the RAID card in the PC. 1-20
