-I have 3 computers from Supermicro with BMC and IPMI. The Supermicro provided utility program IPMIView is good, but the iKVM console redirection facility is woefully unreliable and also seems to be poorly documented! For more details on this refer to [[home_server:home_server_setup:other_services:ipmi_console]].  The 3 computers I have are:+I have 2 computers from Supermicro with BMC and IPMI.

   * Supermicro A1SAi-2750F that is based upon the Intel C2750 SoC Atom server processor (8 core), which has 32GB RAM and I now use as my back-up server   * Supermicro A1SAi-2750F that is based upon the Intel C2750 SoC Atom server processor (8 core), which has 32GB RAM and I now use as my back-up server

-On occasion I have had problems with the operations of these machines.  The computer would just halt, however the BMC / IPMI still seemed to operate.  This has happened now 2 times that I can remember in the past 7 years with 3 such computer setups, so it is very infrequent.  I hope the frequency does not increase!.  The solution to fix was very simple.  A cold reset of the BMC!  This is most effectively achieved by turning off the computer power supply!  I had a similar problem with my first 5 port unmanaged 2.5GB/s switch, again I simply need to cold reset about once every 6 months or so.  My new current 8 port unmanaged 2.5GB/s switch seems more reliable. +On occasion I have had problems with the operations of these machines.  The computer would just halt, however the BMC / IPMI still seemed to operate.  This has happened now 2 times that I can remember in the past 7 years with 3 such computer setups, so it is very infrequent.  I hope the frequency does not increase!.  The solution to fix was very simple.  A cold reset of the BMC!  This is most effectively achieved by turning off the computer power supply! My newest 4x 10Gbe/s + 12x 2.5Gbe/s switch from Xikestor seems to be quite reliable, I do no seem to have needed to reset to date after 12 months from operation/purchase (2026 Jan).
