Supermicro H12SSL-i / H12SSL-NT SlimSAS x8 ports & U.2 SSDs

[lunadesign]

Has anyone connected one of these ports to a U.2 SSD directly (no backplane)?

If so, which cable did you use?

Thanks!

Not on the SuperMicro but Tyan has the same port and a SlimSAS to 2 x U.2 cable - https://forums.servethehome.com/index.php?threads/tyan-s8030gm2ne.28914/post-275698

Acme Micro sells these in US. The other option is to use TaoBao and get yourself a SlimSAS cable with SATA power connectors instead of Molex: SFF8654(SLIMSAS)转SFF8639NVMe（U.2）线缆SAS连接线-淘宝网

Good to know!

The challenge is that I'm hearing (still need to confirm) that there's some leeway in the SlimSAS SFF-8654 spec and that vendors sometimes wire them up differently. So, the Tyan cable *might* not work on a Supermicro SFF-8654 port.

Further complicating things is that I've seen 2 cases (one Supermicro, one Broadcom) where their SFF-8654 cables state they are unable to be connected directly to drives -- they have to be connected to backplanes. I haven't quite figured that one out yet.
