Hot, Warm Setup Storage Based

Hey,

we are planning to setup a new cluster with 5 hardware servers. Each server will use a 2TB PCIe SSD and ~10TB of SAS Storage. We are collecting logs and timeseries. After a few days data should be moved to the SAS storage... I wonder if this is possible without having to setup an explicit Elasticsearch instance / node (as VM or via Docker). So my idea is not to have hot and warm nodes but having hot and warm storage managed by a single Elasticsearch node.

You cannot really control the allocation of shards within a single node. It's best to set up distinct nodes for each storage class and then use allocation filtering (or ILM) to move shards from one class to another. Note that you can run multiple nodes on the same VM.
