Q: We are upgrading from ESX4.x to ESX5.1 or later, would that require a HW version upgrade of the OVA?
No. There is no need to switch unless you need a specific HWv8 feature.
Q: What is the difference between HWv7 and HWv8?
HWv7 runs on ESX4.x and ESX5.1 or later. HWv8 runs on ESX 5.1 or later only. HWv7 may be preferable if the customer is running Delphix in a mixed cluster of vSphere 4.x and later versions.
Q: What are the best settings for ESX and Delphix?
