The environment described in this architecture is one main datacenter containing 10,000 VMs and 100 physical servers. Each VM and physical server has an average of 200 GB of used storage space. All backups will be targeted to a local primary backup repository and copied to a secondary offsite location. Proxies are installed on VMs and use the virtual appliance (hotadd) backup method. The primary Veeam Hardened repository will be on Dell PowerEdge R760xd2 server and the secondary repository will be on Data Domain 9800.

+8+8I prefer RAID 6 for larger drives as it will survive two drive failures. Consequently, though, RAID 6 is slower, so RAID 5 is an option as well.
If you are using larger disks, RAID 6 is a good option as rebuilding a new disk (after replacing a damaged one) can take a long time, and RAID 6 will protect you from another disk failing during rebuild.
I recommend that you talk to your Dell or Partner SE for information regarding Dell hardware.
