Well FedEx strikes again.

Does anyone know if you can swap in the Supermicro SuperQuiet PSUs in these??

the p/s on these units are super quiet. Source: I got one

Sweet! I’m going to order one. Are they adjustable on fan speed too? Or just defaults to quiet?

1. There appears to be two UART cables (and includes a headphone jack to DB9 (I assume RS-232 but haven't checked) mounted to the bottom most PCIE expansion. Anyone know if there's a standard way to use this? Unclear if there's a MCU on these backplanes or if it's for firmware update?

Did you ever figure out what these were for?! Just got my system and am extremely happy with it. Very well constructed and SUPER quiet compared to my old ISILON NL400 that I was using.

Highly recommend this for anyone in the market for it.

Went ahead and pulled the trigger on one of these, seller accepted offer of $415 shipped. Will report back when it arrives, seems like a good addition/upgrade from my CSE847 (6Gbs).

These are for connecting to the SAS back planes. They run at 38400 8N1. You can also use the SAS SES commands to do most things.

I have a X10DRH-CT in my system but when connecting to the AVAGO 3108 onboard a ton of the drives list as "blocked" within the MegaRAID BIOS screen. Going into the config tool I'm not able to see a way to unblock these drives (I have the controller configured as JBOD to pass through the drives for ZFS). Has anyone run into this before? Do you know how to resolve this?

Seems a bit slow, even for hard drives. Wouldn't a native SAS connection be better?

It's fantastically slow compared to SAS. SAS is 12Gb/s, the UART is 38.4kb/s. This interface is used for advanced controls and firmware updates only. There's no way to access the hard drives over the UART interface.

Are you sure? K comes after G in the alphabet, so I always assumed kb was better than gb.

 

[bwahaha]

they're basically serial connection to manage the backplanes themselves, nothing to do with the disks that get attached.
