Since none of my equipment has warranty, I can't speak about the support.
I only own one working board, a epc612d8a, a very nice board.
But the ipmi and bios do lack a bit.
Even though it features the ast2400bmc that Supermicro decided to role out its Redfish to, does not get any updates from Asrack and does not have the html5ikv and I doubt they will ever update it with it.
No oob bios updates from the ipmi.
The ipmi update functionality is broken on the latest version, so even if they would update it, it would be a hassle to actually get it updated.
From time to time, the Java kvm crashes to a blackscreen and won't recover. Only a powercycle or reboot of the BMC recovers that.
Sadly, there is no BMC reboot button in the ui and i haven't tried that with the ipmi-tool jet. So a complete power cycle of the machine it is.
And no postcode snooping in the ipmi.
Which means, the only way to know where it is stuck in POST is to actually look at the Postcode display on the board.
But at least the board has one. Supermicro please?
Had the chance to play around with a EPC612 WS from a friend and the ipmi is the same, the bios at least has bifurcation settings that I haven't found in my d8a jet.
On the SM side of my equipment,
it begins with a few x9drif which don't get the redfish update and frankly suck, so I sold them.
To x10SR.. and DR... Which are on redfish. The bios has everything I need, but sometimes a bit hidden and named unintuitively.
And finally a friends H11dsi of which the ipmi is very nice, maybe I skipped a few updates on my x10 s.
Have another Asus z10pa d8 and the java KVM is the same to the asrock.
Ipmi feels similar. But at least Asus has oob bios updates.
Still don't like it vs the supermicro redfish.
