An EMC customer is looking for options to back up their smaller remote sites with easy remote management, so they want to use Avamar Virtual Edition (AVE). Before installing ESX hardware at the remote sites they want to do a proof of concept using the existing ESX 4.1 server that they have at the data center.
They provisioned 2 TB of virtual disks using VMAX thick provisioning with RAID 5 protection and zeroed out all blocks using eager zeroing. They tested the backup of three servers and do not see an improvement.
According to best practices, what should the customer have done to avoid performance issues?
