Description
SolarWinds High Availability (HA) provides 24/7 uptime for your critical monitoring infrastructure. It protects your SolarWinds platform (Orion/Observability) against OS crashes, application failures, and network connectivity issues.
With HA, you deploy a secondary "Standby" server. If your primary server fails, the High Availability module instantaneously fails over to the secondary server, ensuring you never lose visibility into your network health. It works across subnets and is essential for enterprise-grade deployments.
Key Features
- Instant Failover: Automatically switches to the standby server within minutes of detecting a failure.
- Multi-Subnet Support: Supports failover across different subnets (WAN/LAN) for disaster recovery scenarios.
- Seamless VIP: Uses a Virtual IP (VIP) address so users don't need to update their bookmarks during a failover.
- Database Independent: Does not require SQL Clustering or AlwaysOn (though it supports them); protects the application layer.
- Simplified Upgrades: Use HA to minimize downtime during SolarWinds software upgrades by updating the standby first.

SolarWinds HA vs. OS Clustering

| Subnets | Usually Single Subnet | Multi-Subnet (WAN) |
| Purpose | General OS | Optimized for Orion |
Trending FAQs: High Availability
Q: Do I need a separate license for the secondary server?
A: You do not need to buy a duplicate product license (e.g., NPM SL500) for the secondary server. You only need to buy the High Availability (HA) license for the pool. The secondary server runs in "Standby" mode until needed.
Q: Does this protect the SQL Database?
A: No. SolarWinds HA protects the application servers (Main Poller and Additional Polling Engines). To protect your database, you should use Microsoft SQL AlwaysOn Availability Groups or SQL Clustering.
Q: Can I use this for Disaster Recovery (DR)?
A: Yes. Because SolarWinds HA supports multi-subnet deployments, you can place your primary server in Data Center A and your standby server in Data Center B, providing true DR capability.
Q: Is HA included in the new Observability licenses?
A: HA is included in the Enterprise tier of SolarWinds Observability Self-Hosted. For Essentials and Advanced tiers, it is an optional add-on purchase.
