Dual Port Mini SAS Adapter SFF-8643 to SFF-8644 PCIe 3.0 Host Bus Adapter, 12Gbps SAS/SATA HBA Card for Server Storage RAID Controller

Product works well. However despite the description it does not come with the full sized PCIE bracket which means I am having to jerry rig them for now. **ETA**. Seller reached out and offered a partial refund even though the listing says it only comes with a low profile bracket. Something that I completely missed. So I am changing this to a 5 star review. the product works great. I screwed up in not reading. And despite that they offered to give me a partial refund which I have refused because it isn't their fault.

Good working adapter for SFF-8087 (internal SAS2) and SFF-8088 (external SAS2) on empty PCIe slot. It could be installed properly in the PCIe slot with a full-height bracket. However, It cannot be inserted into the PCIe slot with a low-profile bracket (due to a wrong direction and length of the low-profile bracket included.) According to other reviews, it should be working fine with a low-profile bracket from LSI external SAS2 RAID controller, such as LSI 9286CV-8e. Because I had a bunch of LSI 9286CV-8e controllers from Lenovo SA120 units, I could use a low-profile bracket from it. With a LSI low-profile bracket it can be mounted in the low-profile PCIe slot as expected. Other cheaper adapters (with a small gap between two SFF-8088 ports) will not work with a low-profile bracket, even though we can use an LSI one. I highly recommended this adapter for someone who wants to connect internal-external SAS2 devices with a low-profile chassis, such as 2U servers.

It's a little more expensive than I'd like for what it is, however this adapter worked quite well for converting an existing SAS backplane chassis into a JBOD enclosure. My RAID controller had no problems detecting the backplane/drives through this adapter, and all features such as disk hot swap and drive locate worked fine. Unlike some competing products, there was no mounting issues or bracket spacing problems -- it fit into the case just like any normal expansion card might.

Very good functionality to bad the full size bracket is missing

Unlike another common 8087 to 8088 adapter which had the two ports slightly spaced apart, this one fits into the low profile pic slot (the pcb of the other is too tall, even though it includes a half height bracket). There isn’t much to the product other than that. It’s a simple pcb, so not much to go wrong or anything else. It does use the same bracket as the lsi 9207-8e cards I have. It’s not really a huge deal, but because I have spare half height and full higher brackets, it’s nice to know they are interchangeable if I ever need to switch out the brackets later on. Great product for what it does. I recommend it.

10Gtek Dual SAS SFF-8088 to SFF-8087 Adapter, with Low Profile and Full-Height Bracket Positive: The adapter itself works just fine Neutral: Oversized PCB prevents use of some right angle SFF-8087 connectors Negative: The low profile bracket is not as pictured in the listing, it's simply a shorter version of a standard bracket, and not mirrored like it needs to be. This was ultimately the adapter I needed, and really the only one I could find in 2025. So while it does work, I had to cut down the needlessly long PCB to fit the right angle SFF-8087 cables I had, and I had to mangle the half-height adapter in a vice so I could actually use it in my R720

I am using a Adaptec 8885 along with a Sans Digital MS8X12G SAS3 enclosure. It fails to negotiate all drives at 12G/s when using this adapter. When testing with external ports it works fine, so there is no doubt it is this adapter interfering.

Does what it says on the tin.
