VMS Server Sizing

By: Sean Patton, Published on May 25, 2018

Specifying the right sized PC/server for VMS software is one of the most important yet difficult decisions in IP video surveillance. In the past manufacturers designed and certified that a specific appliance 'box' would support a specific number of cameras (e.g., 4, 8, 16, etc.). Of course, the simplicity came with limited flexibility for expansion.

With VMS software being widely deployed on 'regular' PCs/servers, integrators need to properly specify the right ones. If your machine is not powerful enough for your cameras, you can face all sorts of painful issues and difficult to troubleshoot problems.

The good news is, fundamental guidelines exist to help select the right hardware.

Inside, we explain many of the factors to consider, including:

  • New Technology Impact
  • Key hardware drivers (CPU, RAM)
  • Server Cost Differentials
  • Maximum Throughput
  • Throughput Calculations
  • Bits versus Bytes
  • Smart Codec Impact
  • H.265 Impact
  • GPU Processing
  • Multicast Support
  • Multiple NIC Support
  • Manufacturer Specifications
