VMware VADP
The VADP (vStorage APIs for Data Protection) interface allows for direct connection to the storage array where virtual machines are stored. VADP enables backup products, like NetBackup, to perform a centralized, efficient, off-host LAN free backup of virtual machines. There are a number of variables in the VMware and NetBackup setup that can influence performance in this scenario. Some of these variables or considerations have been listed below
VMware environment depends heavily on the storage performance and this is visible during backup operations.
From the appliance side we should not oversee AdvancedDisk or deduplication capabilities of the appliance and enough leeway should be left for other workload resource utilization. For example HBA's and NIC's are using CPU resources as well and their usage has to be calculated into the overall workload.
In case when MSDP storage on appliance is used to store backed up VMware data, the appliance performance will be limited by target deduplication processing capabilities of the appliance model and appropriate sizing should take this into consideration. All recommendations applicable to target deduplication apply to the VMware VADP backup to the MSDP pool on the appliance.
