What is SonicWall NSv Series?
NSv Series is SonicWall’s virtualized version of next-generation firewall appliance to provide DPI security and segmentation in virtual environments. SonicOSv running on NSv series offers the same feature functionality and security features of a physical appliance. NSv is based on SonicOS Virtual which is a fully featured 64-bit SonicOS powered by SonicCore. NSv Series has the same security as physical appliance and comparable physical appliance performance.

Microsoft Azure
Amazon Web Services
What is the EVC and CPU Compatibility?
SonicWall NSv supports ESXI running on relatively modern chipset Intel Penryn and above (2008). If chipset is, too old the install will halt with following message “This system does not support SSE4_1”.

Limited Nodes: NSv10, NSv25, NSv50 and NSv100

NOTE: Limited Node Models - NSv300 is not offered in Public Cloud (Azure and AWS) .
How does SonicOS calculate nodes?
The supported node count varies by NSv platform. This is the maximum number of nodes/users that can connect to the NSv at any one time, and is displayed on the System Status page in the MONITOR view.

SonicOS calculates node counts as follows:
- Each unique IP address is counted.
- Only flow to the WAN side is counted. WAN includes IPSec VPN
- GVC and SSL VPN connections terminated to the WAN side are counted.
- Internal zone to zone is not counted.
- Guest users are not counted.
  A log event is generated when the node count exceeds the limit.
  
  NOTE: The node counts per each different IP and not the number of VPN tunnel and/or VPN networks, etc. SonicOS counts the node when the traffic is from/to WAN zone. When the traffic is flowing between VPN zone and LAN zone, there is no node count limitations.
What are the supported SonicOSv features?
The SonicWall NSv Series for VMware ESXI has nearly all the features and functionality of a SonicWall NSA hardware appliance running SonicOS 6.5.0.2 firmware. At this time, the following features are not currently enabled in the NSv Series:

Deployment Modes: Tap Mode and Layer2Bridge Mode
Dynamic IP assignment Protocols: PPPoE, PPTP, L2TP
Link Connectivity: Link Aggregation, Port Redundancy

Contact SonicWall distributor to purchase SonicWall NSv. You will receive a fulfillment email with Serial Number and authentication code. Register on MySonicWall with Serial Number to download the OVA and deploy it on your ESXI.
Is there a trail license available?
Yes, You can sign up for NSv 200 1 month trial.
How to deploy/Install NSv?
Please refer to Getting Started Guide for step by step instructions.
Can we add/delete interfaces from NSv?
SonicWall does not recommend adding or deleting interfaces in NSv.
Management Interface is not reachable after changing port to 8443
8443 is NSv reserved port for Safemode interface.
Why is the core file drop down list empty?
If an when core file is created, it will appear in drop down list until it is sent to SonicWall Support Services and when files have been uploaded successfully, they are deleted and drop down list will be empty.
How to configure Virtual Interfaces in NSv for ESXI?
Map the NSv Parent Interface for Virtual Interface to port group with VLAN ID 4095 (Trunk Port). ESXI treats port group with VLAN 4095 as Trunk Port. KB Article: https://www.sonicwall.com/en-us/support/knowledge-base/180406130130215.
What is Safemode in NSv?
Safemode is SonicOSv Management Console. When the NSv appliance is in Safemode, the appliance starts with a very limited set of services and features enabled. This is useful when trying to troubleshoot issues. The NSv appliance can also be configured to boot into Safemode by using the Reboot | Shutdown screen.
NOTE: Safemode UI is accessible only on HTTP.
Why does SonicWall NSv boot into safemode?
The NSv appliance will enter Safemode if SonicOS restarts three times unexpectedly within 200 seconds. Please verify if minimum memory is available and allocated based on NSv model.
What should be the next steps if NSv fails during boot up and instead boots into safemode?
Access the URL mentioned for safemode GUI in management console and download the logs. SonicWall Technical Support will use this to investigate the problem.
What are the GMS Version Supported with NSv Series?
GMS 8.4 and above and Capture Cloud 2.0 will be supported with SonicWall NSv Series.
How do I move my NSv instance from one physical ESXI server to another server?
Here is the steps to move NSv instance from one physical ESXI to another.

Download latest configuration file backup from existing NSv instance/MySonicWall Cloud Backup if enabled.
Deploy OVA file on new server.
De-register the NSv instance from System|License on existing server or MySonicWall.
Register NSv instance on new server.Import configuration File Backup.
What is the purpose of de-registration option in SonicOSv?
De‐registration puts the virtual appliance into the unregistered state and deletes the binding between it and its serial number in MySonicWall. Then you can use the serial number to register the same or another NSv instance. You can de‐register your NSv directly from the SonicOS management interface under Manage->Licenses. Note: Only an NSv registered online can be de-registered using SonicOS Management GUI.
Can we register NSv in closed environment?

Steps to convert your free trial to a production version:
- Purchase a SonicWall NSv license from a distributor. You will receive a fulfillment email with the new serial number and authentication code.
- Log into SonicOS on your free trial instance.
- Navigate to the Updates | Licenses page in the MANAGE view.
