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.
