Lab

 

I'm just gonna leave this here :-)

 

Silent Lab system with IPMI

 

Started from a horribly loud 1U server.

Very quick 1270v3 Xeon but the thermal management was problematic.

Meaning, the fans would hurt your ears even with anti-noise earplugs inserted.

I added a normal fan and removed the 10ge NIC and the SAS Controller.

Next, I used a different PSU and gave up on the case.

Intel's IPMI is also not totally reliable *on this board* and the single PCIe port was another little issue.

But the real problem, can you imagine adding 5-6 disks/ssds to this setup for testing?

Oh yes, and that *is* the Eiffel tower underneath.

 

 

There had to be something better. I ordered a custom built "PC" with a Supermicro Avoton board.

The specs were: Silent. Silent. SAS Backplane. Multiple Intel LAN interfaces. Multiple slots.

Can you see how tiny that CPU heatsink is?

I got a desktop case with (oups) 3.5" SAS backplane, everything else was perfect.

Replaced the 3.5" backplane with 2x 2.5" 4x-slot ones. They have enough space for 10k disks, or SAS SSD (which are often full-height).

One backplane is ending in a SAS plug for a HBA / Raid controller, and the other one is plain SATA onboard.

That way I can switch between Raid and JBOD setups without any effort.

The other SATA ports on the board are kinda for disks, but using disks in the system does not make you happy, since disks can in fact make sounds.

Nothing else in that system makes noise.

The i354 NICs are rightfully great for a standard server, and due to the PCIe slots I can also have either another x4 NIC in there. Already used that with XenServer 6.2 which didn't have drivers for the i354. And next week, who knows it'll be a 10ge NIC instead.

Alltoghether, a Wonderful testing platform.
