Policies are configured based on application requirements and are applied based on the objects that are available. The following table lists the FTT policy options that are applied in different scenarios:

RAID-1 will be used for the Fault Tolerance Method on the host servers. If we are not using the HBA mode for the hosts, then we will have to RAID the individual disks as RAID 0. Sometimes, RAID 5 and RAID 6 over the network are also referred to as erasure coding. This is done inline so that no post-processing is needed. Erasure coding distributes the RAID5/6 stripe across multiple hosts without any overhead or need of data locality. RAID-5 needs a minimum of 4 host clusters, with 3+1 logic, and has to sustain one node failure without data loss. This reduces disk capacity consumption. Erasure coding can guarantee capacity reduction. This policy can be executed on a per virtual machine disk (VMDK) file/disk using the SPDM system.
