Two NIOS-X Servers can be added to an HA (High Availability) group. In case one NIOS-X Server is down, the second NIOS-X Server can take over DHCP lease management without causing downtime. High Availability can be configured as Split Ranges, Active/Active, Active/Passive, Hub & Spoke, Advanced Active/Passive or Anycast (Deprecated). For conceptual information, see *[High Availability for DHCP](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneDDI/pages/186843608)**.*

- <span style="color: #000000">**NAME**</span><span style="color: #000000">: Displays the name of the HA group.</span>
- <span style="color: #000000">**DESCRIPTION**</span><span style="color: #000000">: Displays additional information about the HA group.</span>
- <span style="color: #000000">**HA CONFIGURATION**</span><span style="color: #000000">: Displays whether the configuration is </span>Split Ranges, Active/Active, Active/Passive, Hub & Spoke, Adva<span style="color: #000000">nced Active/Passive, or Anycast.</span>
- <span style="color: #003300">**SERVICE INSTANCE 1**</span><span style="color: #003300">: Displays the service instance associated with the HA group.</span>
- <span style="color: #003300">**SERVICE INSTANCE 2**</span><span style="color: #003300">: Displays the service instance associated with the HA group.</span>
- <span style="color: #003300">**HA Status**</span><span style="color: #003300">: Displays the following status:</span>
  - <span style="color: #003300">Ok</span>

  - <span style="color: #003300">unreachable</span>
  - <span style="color: #003300">unknown</span>

> ⚠️ If a NIOS-X server is disconnected from the Infoblox Portal, the status is shown as degraded. This may occur if the local network is disconnected from the cloud or during updates to the service infrastructure. In the case of updates to the infrastructure, the degraded status should be transitory.
