The below diagram shows logical architecture diagram of Elastic Stack on Dell EMC VxFlex integrated rack two-layer setup that had four SDS and three SDC. The setup of VxFlex two-layer was configured using VxFlex Manager which automates the entire deployment process.
Figure 7. Solution architecture
From VxFlex OS standpoint, there was a single VxFlex OS cluster with a protection domain, consisting of four RHEL storage only nodes that played the role of SDS. Each host is populated with ten 1.92 TB Toshiba SSD drives. These 40 disks are used to create a storage pool from which the usable storage volumes are created.
The VxFlex OS client software (SDC) is installed on each ESXi host in order to access the volumes created in the storage pool, a VMware Datastore was created on each of these volumes. The Elastic Cluster VMs were deployed onto these datastores. The Elastic cluster that is included one Master VM and two Data VMs.
On each of the three SDCs, a single CentOS VM was created. The first to host Logstash, the second Elasticsearch and the third Kibana. All these three VMs could communicate with each other.
