I mean, the OCC and some of the other on-chip cores are based on the 400 series cores, but what I mean is there were/are tons of SoCs from NXP almost purpose built to serve as BMC-style control chips, with reasonably powerful cores and all the peripheral I/O it'd need. These were used (AFAIK) in Sun servers, so I wonder why not in OpenPOWER.
I'm guessing cost/availability is really what it boils down to, since the ASRock chips are probably just that much cheaper and better understood.
- wmf 5y agoI imagine Google was already using ASPEED BMCs in their x86 servers so they kept using it in OpenPOWER. There are some really specific things like PECI and VGA redirection that x86 BMCs need and AFAIK nothing besides ASPEED has those features.
- sennight 5y agoI doubt IBM gave Google any thought in this matter. I'm pretty confident that it has a lot more to do with the way IBM does their market segmentation, and how that is related to hardware + software bundling and firmware. The ARM BMC fits in a HMC shaped hole. https://en.wikipedia.org/wiki/IBM_Hardware_Management_Console https://en.wikipedia.org/wiki/IBM_Hardware_Management_Consol...
