It sounds like we have an enhancement/feature request here: to be able to specify primary storage device where the new image to be created on when calling deployVirtualMachine API.
Where should I file this request, in Github or the original Apache's CloudStack Jira?

In this sense, you can not really balance load across multiple Primary Storages... (I have actually just tested this, having 2 pools with same storage tag, and deploying a few volumes - all of them were created on first storage available...) You could configure them with different storage tags, but not sure that solves your problem - i.e. some Compute/Disk offerings will be targeting NetApp Cluster1, some NetApp 2, some NetApp3 - but this is impractical. Not sure if someone else can shred some light on this scenario ? (I could atm imagine a very specific game with editing storage tags on storage_pool via SQL (scheduled job), in order to "rotate" list of available storage pools...)
