Looks like we need another Microserver category.
Back to Intel CPU, four 1GbE ports, iLO5 (optional?)
Very compact design:
remote iLo needs a kit:
On System Management Chipset
HPE iLO 5 ASIC
MicroServer Gen10 Plus does not support remote management/ out-of-band management by default. The MicroServer Gen10 Plus iLO Enablem
Firmware version is 3.460.115-6465.
Yes, megaraids should support uefi since SAS-1 series from 2011:
But I ran into another problem: overheat. Microserver has very tight layout, so without additional fan for 9271-4i temperatures going over 110 °C (images attached with external fan and without).
Still thinking what to do next.
