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:
|Scenario||Minimum Recommended Hardware|
|PVS managing up to 50,000 hosts * (**)||
CPU: 1 dual-core 2GHz CPU
Memory: 2 GB RAM (4 GB RAM recommended)
|PVS managing more than 50,000 hosts **||
CPU: 1 dual-core 3 GHz CPU (2 dual-core recommended)
Memory: 4 GB RAM (8 GB RAM recommended)
|PVS running in High Performance mode||
CPU: 10 CPUs, with hyper-threading enabled
Memory: 16 GB RAM
HugePages memory: 2 GB
*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.
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.
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)
