dolson11 0 Posted March 6, 2012 I was just curious if anyone knows were it the bottle neck in an NVR. By looking are performance monitor it doesn't seem to be the CPU, Network or Hard drives. It is it the bus? I have a Xeon 2.4 quad core with about 80 megapixels of data with a SAS storage of about 20tb, with 2 Gig ports one in and one out Thanks for you input Share this post Link to post Share on other sites
Soundy 1 Posted March 6, 2012 What NVR? What cameras? What codec? Are you running the VMS on the system as well, or strictly NVR functions? What are the actual symptoms that make you think there's a "bottleneck"? Share this post Link to post Share on other sites
thewireguys 3 Posted March 6, 2012 What is your incoming and out going bandwidth? Why SAS drives? Total over kill for a NVR. Share this post Link to post Share on other sites
Soundy 1 Posted March 6, 2012 What's wrong with overkill? Overkill is fun! Especially if you're spending someone else's money Share this post Link to post Share on other sites
akelley 0 Posted March 7, 2012 What is your incoming and out going bandwidth? Why SAS drives? Total over kill for a NVR. If he's running it on an "off the shelf" server (Dell, etc.) it's possible it came with SAS drives already installed. Look at it this way, it's definitely scaleable. Well, he states 80 megapixels... depending on frame rate that can range from 67Mbps - 402Mbps (@ 5-30fps) using H.264. If using MJPEG, that will saturate a 1Gig network even at 5 fps. These are just rough estimates as I have no idea the actual frame rates of the individual cameras (are these 8 10MP cameras? 40 2MP cameras, etc?) Share this post Link to post Share on other sites
thewireguys 3 Posted March 7, 2012 Without knowing the VMS and the total in/out bandwidth we are just guessing. Share this post Link to post Share on other sites
dolson11 0 Posted March 7, 2012 Thanks for all the replies Dell t310 Server 2.4 ghz xeon with 4gig Ram It is running exacq H.264 Average FPS of 7 ...... maybe its just the way an NVR works. I do realize that it is trying to record and then spit it back out off the same hard drive When I try to view a full screen of live video like 4x4 so 16 5mp camera it just seems so jerky. Yes I know SAS is an overkill but I pulled it off their old pelco system and just replaced all the old 300gb drives Share this post Link to post Share on other sites

I will not be surprised if your video card is weak` need good card to decode H.264 properly Share this post Link to post Share on other sites
thewireguys 3 Posted March 7, 2012 What cameras are you using? How many of them? What is your total in/out bandwidth. Share this post Link to post Share on other sites
