In this ongoing series of articles about the great new features in SFOS v19.5, we’ve covered new search capabilities, SD-WAN load balancing, Xstream TLS FastPath, Azure AD integration, and now this week, high availability enhancements.
Sophos Firewall high availability
Sophos Firewall supports high availability (HA) clustering of two appliances in active-active or active-passive operation for higher performance and redundancy.
SFOS v18 introduced a major new enhancement to high availability with QuickHA setup that makes configuration almost a plug-and-play exercise.
If you’re not familiar with the various HA modes or how to use QuickHA, check out the great two-part video series on these topics.
What’s new with high availability in v19.5
Making management easier
Several user interface enhancements improve the status and visibility of your high-availability cluster with a new control center widget, enhanced status panel, and new node names for easy device identification.
Node Names help identify the particular device in the cluster and are shown on the browser tab, HA status page, HA logs, command line interface, and Control Center to make it very easy to know which device you are currently interacting with.
Redundant HA links
High availability pairs can now be synchronized with redundant HA links to add resiliency and prevent split-brain conditioning.
Up to four links can be provisioned for HA pairs using physical, LAG, VLAN or unbound interfaces. Conveniently, LAG configuration happens automatically behind the scenes in QuickHA mode.
