Exemplo de discos proxy do Avamar localizados em diferentes datastores

Attached Disk  : [VMFS-Production-Tier2-12] proxydisk.vmdk
Attached Disk  : [VMFS-Production-Tier2-70] proxydisk_3.vmdk

Sugira envolver o administrador do vCenter para fazer um Storage vMotion em um datastore completamente diferente para essa VM proxy.
