You have been tasked with installing a 1 TB Avamar AVE server in an ESX environment for a new customer. The customer has thick provisioned the correct amount of LUNs with the correct sizing. The Performance Assurance Tool (PAT) has been loaded on the ESX environment and ran for 24 hours. The results come back and the test did not pass the requirements for an AVE installation.
