Do you plan to add support for Datastore Clusters to Veeam reporting? I'd like the "Datastore Capacity" and "Datastore Space Usage History" reports to show Datastore Clusters rather than individual datastores. We have nearly 200 datastores, so looking at individual datastores is not much use. In vCenter we group them into datastore clusters by ESX cluster and storage tiering: eg Prod 1 Tier 1 and Prod 2 Tier 3 etc.
As we're starting to use Storage DRS to manage the placement of VMs, we're not so concerned about the disk usage of individual datastores but look at the higher datastore cluster level. If a datastore cluster is getting close to 80% we usually add another 2TB LUN.
So far I've been using vCenter graphs, by clicking on the datastore cluster, clicking Performance, View: Space and Time Range: 1 Year. The 1 Year Summary shows the usage over time. Not ideal, but I can try to guess the overall trend in usage. It would be great if Veeam could help us with this capacity planning.
