Using the μPCIe connector (J10108)

(1/1)

pocock:
The manual:
https://wiki.raptorcs.com/w/images/e/e3/T2P9D01_users_guide_version_1_0.pdf

mentions a μPCIe connector (J10108)

How many lanes does it support?

Can anybody give any example of products that can be connected with this?  For example, can it be used with an M.2 or U.2 adapter for SSDs?

pocock:
The manual suggests it is 4 lanes (PCIe 4.0 x4)

The errata states it is an Oculink SFF-8621 physical connector but it is not completely wired for Oculink

Nonetheless, do the PCIe lanes work sufficiently for an SFF-8621 to U.2 NVMe cable?

Here is an example of the cable CBL-SAST-0956 from Supermicro

The cable is not very expensive, I might simply buy one to try it.

pocock:
I notice the micro PCIe socket is right under one of the PCIe cards.  This means it may be better to use a cable with right angle (RA) connector like this:

Supermicro CBL-SAST-0955

I've seen Raptor offer the cable when you buy a Blackbird combo, so it's presumably a supported use case. I'm thinking about doing that after I've tested my incoming Blackbird for stability and gotten a feel for its performance with SATA.

Has anyone tried this yet?
