There is an IBM ServeRAID-8i controller, also known as Adaptec ASR-4005SAS/256 Zero Channel RAID controller (256MB RAM, BBU 13N2256, PCI-X), p/n: 25R8115, FRU: 39R8731.
It is clear that this is a Zero Channel, however, two facts are confusing - the presence of some kind of 20-pin IDC-type connector, and the presence of space for some kind of unsoldered 40-pin connector on the reverse side.
Maybe it's not that Zero after all.
I couldn’t find any information (or even mention of such a model) on this controller on a bunch of Adaptec and post-Adaptec sites. It's similar to the 4000, but it doesn't have any connectors at all, and it's older.
Drivers for all OS, incl. Windows x64, and IBM CDs with documentation and software/firmware are already found. Unfortunately, there is not a word about these connectors in the descriptions from IBM.
I'm looking for any information about what kind of connectors these might be and their pinout.

The IBM ServeRAID-5i and 6i (IBM 71P8627 ServeRaid 6i) appear to have that same 20pin but nothing found in their docs.

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

No, they are not the same. ServeRAID-5i has a 16-pin connector, and it is a Ultra320 SCSI controller, not SAS.
Although, ServeRAID-6i has a similar 20-pin, it is also a Ultra320 SCSI controller (but 6i and 8i both use the same processor - Intel IOP321, could this have any relation to it?).
Maybe Adaptec made these controllers as OEM for other brands, not only IBM?

Yes I knew there were differences between 5i, 6i and 8i but just looking for any info on their IDC connectors turned up absolutely nothing (which seems very odd)...
Maybe there are other OEM that are the same. Judging from what little info out there, adaptec first released the 5i about 2002 and then the 6i, then 8i in 2005.
The x366 server had the 8i as an option "Integrated Adaptec AIC-9410 serial-attached SCSI (SAS) controller. Support for internal RAID arrays using an optional ServeRAID-8i adapter." <redp4006.pdf>
Wonder if Dell used them too, with a different name ?

the footprint connector on the back look similar to an JTAG port which is used during development and unpopulated when in production.
the IDC connector is unknown, but if they are not mentioned in the document then it also being used as some sort of debug port. Or it can be used for some future feature but it got dropped hence no mention in the document.
