Optimal configuration for 2 high powered nodes

Elastic Stack Elasticsearch
1

Hi,

I am using 2 fairly high powered physical machines as ES nodes, each has
96GB of memory and 1TB of RAID10 SSD.

The Elasticsearch database is currently around 300GB with 450,000,000
documents.

I am trying to understand which of these configurations would be optimal?

  1. 1 x ES instance on each machine with 30GB Heap (for pointer
    compression reasons)
  2. 1 x ES instance on each machine with 57.6GB (60% of total memory)
    Heap
  3. 2 x ES instances on each machine, 30GB Heap for each

Hi,

I think the 2nd proposition could be the worst. With more than 32GB the JVM will use uncompressed pointer.
Take a look at this : http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/_limiting_memory_usage.html

Hope this help

I'd go with option 3 and use puppet to manage it.
