Prerequisites

Before you install and configure Elasticsearch, you must consider the following:

Elasticsearch:

• For details about the supported Elasticsearch version, refer to the Prerequisites section in the SpeechMiner page in the Genesys Supported Operating Environment Reference Guide.
• All Elasticsearch nodes should be located on the same local network.

Operating Systems:

• For details refer to the SpeechMiner page in the Genesys Supported Operating Environment Reference Guide .

Indexer:

• Indexer cannot be run on either Linux or Docker.
• IIS Web Service must run on the Indexer machine.
• Multiple indexers can be run with a Load Balancer.

Architecture:

• SpeechMiner does not support active-active site deployment. To create a backup of a cluster using Elasticsearch API refer to Elasticsearch - Shared File System Repository and Elasticsearch - Monitoring Snapshot Progress.

Shards and Nodes:

• 1 shard is required for every 2 million interactions in a Genesys Interaction Analytics (GIA) solution and 20 million in a Genesys Interaction Recording (GIR) solution. For example, for a GIA solution if you have 32 million interactions you must have 16 shards.
• The number of shards cannot be changed after SpeechMiner indices are created. SpeechMiner indices are created when the Elasticsearch Migration Tool is run or when you first run Uplatform (when migration is not required).
• You must have one Data node for every 8 shards (16 million interactions in a Genesys Interaction Analytics (GIA) solution and 160 million in a Genesys Interaction Recording (GIR) solution).
• A minimum of 2 Shards and 2 Data nodes are required for redundancy.
• It is recommended that you use 3 Master nodes. Note: if you only use 1 Master node, the entire system is down when your 1 Master node is down.
• You can use the same Elasticsearch node for both the Master and Data node when working with 5 or less Data nodes.
• If you have more than 5 Data nodes, we recommend that you have 3 separate Master nodes.
