@gkasprow @marmeladapk Do you agree?

CPCIS is not compatible with DIOT in any way because CPCIS is 160mm while DIOT is 220mm length. One can order chassis from Schroff with a CPCIS backplane and 160 or 220 lengths. we should not call it CPCIS any longer to not cause confusion. We are using the CPCIS backplane only. CPCIS is using PCI/USB/ETH interfaces, both from the controller and peripheral side. We can only consider the compatibility between DIOT (6HP panels) and Sinara (4/8HP panels) Schroff CPCIS-220mm has 4HP spacing, but we will use a much cheaper open-source CERN chassis and backplane. 6HP has an advantage that all existing boards can fit including Kasli, Stabilizer with mezzanine, Mirny with mezzanines.

I've updated top comment to contain clear information on compatibility and removed redundant information from the table.

LGTM DIOT backplane is electrically 100% CPCIS backplane, The only difference is slot spacing. The open-source DIOT backplane was demonstrated to work at 12Gbit/s. I think we should event not consider 220mm Schroff enclosures. They are expensive and proprietary which contradicts with Sinara ecosystem philosophy :) We can still use existing 4HP modules with adapters in DIOT. We simply use 2HP blind panels to separate the panels.

Ok, so as you suggested:

we should not call it CPCIS any longer to not cause confusion.

kaolpr commented 2 years ago

However, I'd keep the CPCIs incompatibility warning due to visual resemblance (module length can be overlooked).

gkasprow commented 2 years ago

Let's rename the repository as well.

Added table from top post to wiki.
