You'll likely be wasting you money.
As mentioned above If you use 4TB drives with Raid 5, regardless of the vendor or storage array in use, you can pretty much guarantee you will have data loss and if you're tiering, that data loss will be catastrophic. This isn't something 3PAR specific it's just a fact of life, Raid 5 can't adequately protect drives of this type. Firstly there's the much higher platter bit error rate on NL and then the potential rebuild times involved for drives of this size increases the likelihood of a second (overlap) failure.
You need to engage with someone who understands how this really works. Adaptive Optimization (SUb LUN Tiering) is not an archive solution, nor will it allow you to pin or place data based on your own criteria, such as age, last access time etc. It's designed to squeeze the best possible performance out of a minimal amount of SSD. So unless your 100TB of data is all very very hot (highly unlikely) the majority will end up on NL almost immediately and not SSD.
You can hit the same capacity point on NL with 6 more drives using Raid 6 14+2, but I'd urge you to contact a local reseller / HP resource to get this validated, otherwise it could end up being a rather expensive mistake for all involved.
