I didn't see much info on this card in the interwebz and asked in the RAID/HBA forum. Thanks @Sleyk for sharing his knowledge.
Dell PN: TFJRW are listed for $64.95 + FS.
Note these have newer SFF-8644 connectors though the card is 6gbps. And with dual SAS2308, the idle power draw of 14w is some thing to keep in mind.

Also I saw listings for different Dell PN: 1V1W2 which actually say 9206-16E but lowest was about 119 OBO, for a NIB card.

Here is the link to discussion in the RAID controllers on this site.

I had planned on using these in a Dell C6100 and trying to route 2 sets of cables back into each node so that I could use the front bays as well as external enclosures later if I wanted to. But coming up with an area to route the cables back into proved pretty much impossible.

What is the real purpose of a 16e card ?

I'm studying which are the best HBA topology for a high throughput and this card even if it's work on a PCIe 3.0 8x, you will have at best an average of 3.94 Gb/s per port.

Maybe i'm wrong but:
- 16 ports SAS-2 that requires 96 Gb/s bandwith
- 8x PCIe-3.0 provide 62.96 Gb/s bandwidth

So your hba will be limited to 62.96 Gb/s at the best (at full load).

Maybe i'm missing something, because even with the sexy 9300-8e card (that i'm looking for) you will require exactly the same bandwidth (but less ports to fullfill) and you will have at the end an average of 7.87 Gb/s per ports (at full load)

My computations let me thinking that we have reals differences of controller requirements in term of bandwidth and what they can have from their PCIe connection.

In this regard, the 9208-8i is a good option since at full load you can saturate each ports at 6Gb/s

A storage array like a SC8000 is built for iops over throughput. And in the case of the SC8000 specifically, the expansion limits of the array are mostly constrained by the number of PCIe devices you can add to each controller node - the SC8000 controllers are really just dell R720 servers with SCOS instead of linux or windows or whatever. So when growing an SC8000 you only have so many slots to add HBAs (for more and more disk shelves, depending how many shelves you want to daisy-chain on one SAS bus), FC-HBAs (target mode, for clients to access the array), 10G-NICs (iSCSI targets), etc. And a lot of the slots in those servers are only 1/2 height slots - so Dell convinced them to build a quad-port low-profile HBA as linked in the OP so that us SC8000 owners can use those 1/2-height slots for connecting more back-end disk shelves.

As @TuxDude mentioned, it's not always about more performance. Sometimes it's just about being able to access more drives.
When you only have spinning disks in an array, more drives is more performance. Doing 30000+ IOPS against an array of spinning rust with no SSDs means a LOT of spinning rust, with no need for the full 96 gbit of bandwidth that the SAS lanes could theoretically supply.

Can i use this card in a non dell server? Does it need firmware update?

When i installed perc6i which i pulled off from a dell t5500 and tried to boot centos 6.7, it hanged forever because of megaraid sas driver problem. Do you have any idea?

I'm in for 2 as I could really use 4 ports in a low profile card.

Most likely you can use it in a non-Dell as I am planning to. Even if it does work without a firmware update I would still do one. Chances are good that it is old enough that the LSI driver will complain about versioning.

Got the card. It is NIB with both Dell & LSI stickers outside of the box. Flashing to the latest LSI 9206-16E was a breeze compared to the Dell H310. I have a love hate relationship with them :). Sas2Flash reported two 2308_2(D1) controllers with different SAS addresses. I just had to flash them each.

Now, I need to start looking for the 8644 cables at a good price..

Yeah, this card is awesome to connect 16 drives with pcie 3.0 bandwidth. Can I make another hot milf/sexy baby reference to this card? Heheh...

I have been searching around for cheap cables for these cards too. If I find any more, I will post here.

Ok, cheapest I've found currently is from China at $8.50/cable. Not too bad if your gonna grab 4. ($8.50 x 4 = $34.00)

Genuine Molex sff-8644 TO sff-8088 External Mini Sas Adapter Cable 6ft 2m

If you wanna buy from the States, its a bit more per cable. Seller wants $20 bucks, but you can best offer for a little lower.

Dell YJXMR Mini SAS SFF-8644 to SFF-8088 6.5 foot SAS Hard Drive Cable New

I would just buy from China and wait a bit for it to arrive.

I will also do a search later on the web to see if maybe a server outlet or so has them any cheaper.

I actually haven't setup this type of cable in a 9206 16e with drives yet, but I used these exact types in a 9202 16e card. At the time, that particular card was very rare and hard to find. It was going for like $200 bucks or so on eBay, but I wanted one so bad! I think same interface should work? The 9202 is pcie 2.0 though, while the 9206 is pcie 3.0. I don't see why it shouldn't show the drives as it connects on the same new sff 8644 interface though.

Thanks for the thread. This external sas card was exactly what i was looking for - ordered one and four 8644 cables.

I think the 8644 to 8088 cables should work as it is sas to sas. Not sure on the 8644 to sata though. Might work too, albeit it might be out of specs.
