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||Hard disk space|
|All Versions||PVS managing up to 50,000 hosts * (**)||2 GB RAM (4 GB RAM recommended)||1 dual-core 2GHz CPU||Processor requirements increase with greater throughput and higher number of network interfaces. Memory requirements increase for networks with more hosts. The requirements for both of these components are affected by configurable options, such as setting a long report lifetime.||
Disk space requirements for PVS vary depending on the amount of data and length of time the data is stored on the system.
|PVS managing more than 50,000 hosts **||Memory: 4 GB RAM (8 GB RAM recommended)||1 dual-core 3 GHz CPU (2 dual-core recommended)|
|PVS running in High Performance mode||16 GB RAM (HugePages memory: 2 GB)||10 CPUs with hyper-threading enabled|
*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)
