Generally I don't use IPMI on these systems. I have had trouble with the PCIe slots. Specifically, on the dual core boards some slots are serviced by one set of hardware and other slots by other sets of hardware. Consequently, if you don't have all cores populated then corresponding PCIe slots will not work. Can't say about the four core system, though. > I would consider looking at SGI UV, ultraviolet system for a fat node type > system but they are not cheap.

Support from SM sucks too. :) > On Sep 17, 2013 12:17 PM, "Michael Chen" wrote: > >> I'm considering bidding on this 48-core box: >> >> http://www.ebay.com/itm/**Supermicro-A-Server-1042G-TF-** >> 1U-H8QG6-4-CPUS-48-cores-2-**2Ghz-128GB-RAM-/151119828428?** >> pt=COMP_EN_Servers&hash=**item232f7195cc >> >> Does anyone have experience with it and can I use all the cores? >> >> Thanks! >> ______________________________**_________________ >> freebsd-questions@freebsd.org mailing list >> http://lists.freebsd.org/**mailman/listinfo/freebsd-**questions >> To unsubscribe, send any mail to "freebsd-questions-** >> unsubscribe@freebsd.org " >> > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" >
