Refer to the installaiton guide, the eDiscovery platform must require 8100 or 8200 appliance. can I install in whitebox? what need to pay attention during the setup?
If the appliance meets the pre-reqs it should be OK.
The only thing I can think of that could cause an issue is an issue when trying to grab the service tag and manufacturer for licensing purposes, sometimes the WMI calls do not capture the information - if this happens you may struggle to apply a license, in this situation you'd need to contact support who have instructions to follow.
you can build your own clearwell server (VM or physical) but in order to do so, you need to purchase a specific license from veritas. Trace3 can help you with that if you're in the USA. just let me know.
