Virtual Machines What is a virtual machine? A computer with the operating system and added software that does not on dedicated hardware Multiple VMs can run on the same physical hardware server and share its resources To the network each PC seems just like a stand-alone one

Virtual Machines Where does this meet our business? IT users purchase very powerful hardware server and attempt to run as many virtual PCs on those The requirement to run NVRs on such machines is growing This is less relevant for display stations (workstations and VMDC) as these are considered users PC and not servers

Virtual Machines Advantages: Hardware cost is shared by multiple servers Redundancy solutions can be offered Saves space, power and HVAC resources

Virtual Machines Disadvantages Physical server prices are very high VMs tend to be under powered if too many share the physical server Setup and resource allocation need to be done with attention to system needs

Virtual Machines Where do we stand? Vicon does not test nor approve specific VMs (there is an unlimited number of combinations) Our recommendation is as follows: Ensure the VM meets the minimum requirements for NVR Verify you have a network card dedicated to the NVR and not shared by others Verify the hard drives for recording are dedicated and not shared Verify that the overall load on the physical server is balanced as NVRs take much more resources to run than typical IT servers Currently VM redundancy has not been tested but should be supported
