So assuming i understand most of the stuff correct.
If i buy a supermicro BE16 i have 1 SFF8087 connector. So i need a SFF8087 -> SFF8087 cable to drive all 24 drives.
I quote jgreco
I am not sure what for SAS card to use, and if it matters: SAS2008, SAS2308 or SAS3008.
Found some interesting stuff on the forum
But also
Expected motherboard: X11SCL-F, case: 846BE16-R920B (sas2 ?)
Does it still up?
Do they all support staggered spinup?

The BE16 (or 12Gbps BE1C) option brings out the attached bays as a single SFF8087. For a 12-drive SATA array, this is an ideal choice because there is no contention on the 24Gbps link and the cabling is stupid-simple. Very attractive option. For a 24-drive SATA array, I still think this is probably just fine because you're not likely to actually hit contention issues

Less power is better, certainly if no impact on the performance. But also read that SAS 2008 seems a bit "broken"The LSI SAS 2308 chipset has better performance than the LSI SAS 2008 though both are well-supported and well-recommended.
Main difference between SAS2008 and SAS2308 is PCIe 2.0 vs PCIe 3.0, unless you're using SSDs there won't be any difference in performance, SAS2308 also uses a higher voltage, hence a little more power (~6w vs ~9w) and produces more heat.
On the subject of SSDs, I believe the TRIM implementation in the newer more expensive SAS3008 is also considered “less broken” than in the SAS2308, but both are considerably better than the old SAS2008.

which seems a SAS3008.The best SAS HBA is LSI 9300. Actually iXsystems uses them in their FreeNAS certified servers.
