Clearly VMware isn't really looking at this thread, but I thought I would revive it.. STILL with vcsa 6.7... using LSI Logic Parallel, 13 disks on 1 controller. (Oddly, the appliance OVA is configured with 2 LSI Logic Parallel Controllers, but nothing is attached to the 2nd one...)
OS is PhotonOS so they should have full control of this relative to driver support etc..
