Hardware Requirements

Enterprise networks can vary in performance, capacity, protocols, and overall activity. Resource requirements to consider for PVS deployments include raw network speed, the size of the network being monitored, and the configuration of PVS.

The following chart outlines some basic hardware requirements for operating PVS:

Version Installation scenario RAM Processor Hard Disk
All Versions PVS managing up to 50,000 hosts * (**) 2 GB RAM (4 GB RAM recommended) 1 dual-core 2GHz CPU 20 GB HDD minimum.
PVS managing more than 50,000 hosts ** Memory: 4 GB RAM (8 GB RAM recommended) 1 dual-core 2 GHz CPU (2 dual-core recommended) 20 GB HDD minimum.
PVS running in High Performance mode 16 GB RAM (HugePages memory: 2 GB) 10 CPUs with hyper-threading enabled 20 GB HDD minimum.

*The ability to monitor a given number of hosts depends on the bandwidth, memory, and processing power available to the system running PVS.

**For optimal data collection, PVS must be connected to the network segment via a hub, spanned port, or network tap to have a full, continuous view of the network traffic.

Note: Please research your VM software vendor for comparative recommendations, as VMs typically see up to a 30% loss in efficiency compared to dedicated servers.

High Performance Mode

To run PVS in High Performance mode, a minimum of two of the following types of Intel NICs are required; one as a management interface and at least one as a monitoring interface:

  • e1000 (82540, 82545, 82546)
  • e1000e (82571, 82574, 82583, ICH8.ICH10, PCH.PCH2)
  • igb (82575, 82576, 82580, I210, I211, I350, I354, DH89xx)
  • ixgbe (82598, 82599, X540, X550)
  • i40e (X710, XL710)
