I am a novice with K8S but experiences with Elasticsearch.

I want to run about 8 Elasticsearch pods per server and have each pod claim a NMVe volume.

There will be about 6 servers.

What is the best way to do this?

Do I specifically need to set up zoning to ensure replicas are distributed across servers?

ECK sets up a default affinity rule so the Kubernetes scheduler avoids scheduling 2 Pods of the same Elasticsearch cluster: [Advanced Elasticsearch node scheduling | Elastic Cloud on Kubernetes [1.4] | Elastic](https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-advanced-node-scheduling.html#k8s_a_single_elasticsearch_node_per_kubernetes_host_default).

You can tweak these rules yourself, and I also suggest setting up availability zone awareness: [Advanced Elasticsearch node scheduling | Elastic Cloud on Kubernetes [1.4] | Elastic](https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-advanced-node-scheduling.html#k8s-availability-zone-awareness).
