The solution leveraged VMware vSAN storage for all the VMs that ran the SENSR processing services. VMware vSAN storage was provisioned with a RAID 1 storage policy to provide the best fault tolerance with the least write latency penalty. RAID 1 protection consumes more disk space than other available RAID options but provides better file access performance. The vSAN datastores configured on the VxRail cluster provided local disk mapping for all the storage needs of cluster-hosted VMs, including the operating system and all other local files.
