I currently have a Dell T110 II with 4 GB of Ram, (2) 2 TB WD Red Hdds (no raid), and an Intel Xeon 1230 V2 (Ivy Bridge Xeon 4 core w/HT).
I am running 13 ACTi cameras on the NVR 3 software. Most are 3-5 MP. 80% record constantly during the day at a lower FPS (10 or lower) and higher FPS (15 FPS) when a motion event is triggered (which might happen on 6 cameras at once). At night they are all motion with few events triggered.
My questions are in regards to RAM and Hard drives since going from 8 to 13 cameras we have had a slow down in viewing past recordings (on clients or the server itself).
Is there a practical limit to the amount of ram for a NVR? I see that 4 GB is the general recommendation from many people, including ACTi, and it works great for recording but I am wondering about when we are viewing recordings. Will I see a boost in viewing ability by increasing my ram on the server to 16+ GB or even 40+ GB? I cannot install more ram on the current system, unfortunately, since the computer has Win 7 32 bit (thanks to some other software running that has to have it...) and we are in the market for a new CCTV server so we are looking at ram configurations.
Additionally, the harddrives. Does anyone have a problem viewing multiple cameras at once in a 13-24 camera environment with 7200 RPM Sata drives? Do any of you all use raid or SAS drives?
We are looking at a new CCTV server and have access to some last gen Dells for pretty cheap. Most are 2 x 2.67-3 ghz ghz older corei quad xeons with 24-48 GB of ddr3 ram and 2.5" SAS hdds. But we weren't sure if this we should focus on RAM or hard drives.
