Overview

This topic describes the limitations and restrictions that apply when implementing high availability (HA) and disaster recovery (DR) for Cisco IoT Field Network Director (FND) with a Postgres database.

Here are the restrictions to use HA and DR on Cisco IoT FND with Postgres:

  • HA is supported for both Oracle and PostgreSQL deployments; Oracle deployments utilize Real Application Clusters (RAC), while PostgreSQL deployments utilize the EnterpriseDB PGD solution.

  • In Cisco IoT FND Release 5.1.1, the HA solution supports a maximum of 10,000 devices. Additionally, you must configure firmware operations to use a maximum of 5 threads and restrict PnP image upgrades to a maximum of 5 devices concurrently.

  • Fog Director HA and disaster recovery are not supported as part of this solution.

  • InfluxDB is not part of this solution; all time-series data is stored in the EnterpriseDB PostgreSQL database.

  • TPS Proxy HA is not supported; if the TPS node becomes unavailable, it must be manually brought up at another site.

  • Database HA requires the EnterpriseDB Standard Postgres with Postgres Distributed (PGD) solution; the community version of PostgreSQL does not support this architecture.

  • Cisco IoT FND application servers run in a multi‑active, standalone mode; JBoss clustering across multiple subnets or data centers is not supported.
