From VxFlex OS standpoint, there was a single VxFlex OS cluster with a protection domain, consisting of four RHEL storage only nodes that play the role of SDS. Each host had ten disks and was fully populated with 1.92 TB SSD Toshiba disks. From the available 40 disks within the storage pool, different volumes were carved out.
The VxFlex compute nodes had SDCs installed on ESXi hosts. From the volumes in VxFlex OS, datastores were assigned to ESXi 6.7. One SQL VM was deployed on each of the datastore, thus there were three SQL VMs deployed on to the VxFlex cluster. All these three VMs could communicate with each other.
For detailed configuration of VxFlex integrated nodes, see Appendix.
