Checking requirements

You must be familiar with VMware, Xenserver, Microsoft Hyper-V or Linux KVM virtual environments in order to deploy virtual Stormshield firewalls. The tables below set out all the technical requirements.

Requirements by virtual firewall model

Model	Module	Value
EVA1	RAM HDD vCPU	max = 2 GB 10 GB (2 GB swap) max = 1
EVA2	RAM HDD vCPU	max = 3 GB 10 GB (2 GB swap) max = 2
EVA3	RAM HDD vCPU	max = 6 GB 10 GB (2 GB swap) max = 4
EVA4	RAM HDD vCPU	max = 8 GB 10 GB (2 GB swap) max = 4
EVAU	RAM HDD vCPU	max = 64 GB 10 GB (4 GB swap) max = 16

An EVA must have at least 1 GB of memory. You are advised to set the memory to at least 2 GB if you use the antivirus and sandboxing analysis features frequently.

IMPORTANT
Before reducing the amount of memory of an EVA in production, ensure that the new limits that will be applied to it are compatible with the existing configuration.

Requirements relating to the hypervisor

Number of interfaces represents the number of interfaces connected to the virtual machine.

	Version of the hypervisor	Number of interfaces
VMware ESX/ESXi	Version 6.5 and 6.7	Min. 1 interface Max. 10 interfaces
Citrix Xen Server	Version 7.6	Min. 1 interface Max. 7 interfaces
Microsoft Hyper-V	Windows Server 2012 R2 and 2019	Min. 1 interface Max. 8 interfaces
Linux KVM	Red Hat Enterprise Linux 7.4	Min. 1 interface Max: depends on the Linux vendor chosen
