The time you describe for the boot up process is within the average for this board. Keep in mind that the booting up time is determined by several factors like the embedded devices contained in the board (Baseboard Management Controller, Management Engine), total amount of RAM, PCI devices attached. RAID cards are particularly slow to load due to their integrated processor, cache memory and HDD recognition process.
Something else to consider is that server machines are made for different applications and it is not expected to reboot the server as often as we could do it with a desktop or laptop computer.
If by the other hand you see any POST error messages please let us know.
Hope this helps.
