Pulse Appliances can be deployed in several ways as described in Determine Topology and Connect the PCS device(s) to the network
If PSA-7000 appliance in any flavour is deployed in One arm mode (Only Internal Port is Enabled, Configured & used), then only 4 CPU Cores gets utilized for the processing of the Network Traffic (Inbound/Outbound). However, all the 8 CPU Cores get used for other internal functionalities.
This will leave 4 CPU cores unutilized for handling I/O Network traffic. And, may not give you an optimal performance compared to a 2-arm Mode.This issue applies to :
• Both PCS/PPS devices.
• All flavours of PSA-7000 deployments (such as HW, Virtual or Cloud) and on all supported software versions.This issue doesn’t apply to :
• Any flavour of PSA-300, PSA-3000 & PSA-5000.
• Any flavour of PSA-7000 when 2-arm Mode is deployed (Both Internal & External ports are Enabled, configured and used). Note :
This can be checked under System -> Network -> External Port.
