External eSata Port Multiplier

I have a Studio XPS-9100 with an i7 960.  I am trying to determine if the eSata on the board supports port multiplier.  For example if I attach an external multiple HDD box via eSata will more than 1 drive be recognized?  I already know it is enabled and I have used it with an enclosure that has 1 HDD.

I would appreciate any feedback that can be provided.

Thanks
