We discussed this topic recently on one of the Russian-language threads.
As it stands now, the only supported mixed config is preconfigured external DS4246 with 6x SSD + 18x SATA.

We need some google translate integrated in Communities J In the storage best practice preso for FlashPool… it give per stack, but not per shelf… so looks like to get 12 SSDs it is 6 per shelf across 2 shelves.
¡ In mixed SSD and HDD stacks
– FAS2240 : 3 external(+1 internal) shelves (6-12 SSDs) per stack
– FAS2220 : 2 external(+1 internal) shelves (6-12 SSDs) per stack
– FAS3xxx: 2-4 shelves (12-24 SSDs) per stack
– FAS6xxx : 2 shelves (12 SSDs) per stack

Yeah, I felt into the same trap and argued in the other thread that Flash Pools bring mixed SSD+SAS *shelves* to the table.
But Russian guys quickly proved me wrong with a pile of supporting docs! ;-)

From the Flash Pool Technical FAQ:
Can SSD and HDD be mixed in the same physical disk shelf for Flash Pool?
Answer: The DS4246 disk shelf supports mixing SSD and HDD (specifically, SATA) drives in the same disk shelf (SSD + SAS are not supported in the same shelf). The DS4243 does not support mixing SSD and HDD in the same shelf. Support for mixing in the DS4243 can be requested by PVR.
