These are ESD drives, a faster version of the popular SMD interface.  
It looks like your drives have the dual-ported option. 

It's not the disk
that has to be supported by OS; it's the controller.  Is your Emulex
controller a QD32, QD33, QD35, or something similar?  These are common
SMD to MSCP adapters and ought to work just fine.
