IMPORTANT:
Combined backend transfers:
In Thin Provisioned environments, the overall backend transfers at the RAID group level are reported
using combined backend transfer metric. For a Thin Provisioned V-Vol where the ThP pool is associated
with multiple RAID groups, the backend transfers are not tracked to the corresponding RAID group
level. The backend transfers contributed by all V-Vols in a ThP pool are combined and reported as
combined backend transfers for each participating RAID group. It implies that the combined backend
transfer is shared among each of the participating RAID groups.
The following table lists the details displayed in the Statistics section.
