Bias-Free Language

For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Feature Description

The VPN Manager Recovery Support feature enables the recovery of chunks after a VPN Manager (vpnmgr) crash. To recover chunks after the crash, the chunks are stored and allocated to a particular VPN Manager in the local VPN Manager.

When a pool VPN Manager crashes, it recovers the chunk from the local VPN Manager and all the used IPs from all the Session Managers.
