Talos II / Resetting Talos II to "Factory Settings"
« on: April 05, 2020, 02:20:08 pm »
Is there an easy way to reset an Talos II back to factory settings so I can go through the setup process again?

I changed the passwords per documentation but can't SSH to OpenBMC, nor use the website to login.

Talos II / Building a Talos II computer
« on: March 24, 2020, 02:12:31 pm »

I have the following equipment

I'm trying to connect the various components, get Debian installed so I can start virtualize some workloads (mostly for development and testing). There seems to be a disconnect between the Supermicro chassis documentation and that of the motherboard, especially how cables are connected from chassis.

A couple of questions:
  • The backplane SAS-836EL1 comes with an 16 port extender. If I connect it to the HBA, would it be sufficient for the 16 drives?
  • Which cable is used to connect the HBA to the backplane? From the backplane documentation, I'm gathering a SFF-8484 is required but the HBA specification states it has 2 Mini-SAS HD SFF8643 internal connectors. I'm a bit lost.
  • I'm trying to figure out which backplane cables need to go where. See attached picture. I'm not seeing any codes on them and thus can't figure out which cable they are. I have not removed the backplane from the chassis.
  • I'm trying to figure out which power supply cable should be connected where on the motherboard (to be done last).
Are there any videos of folks doing a build or going through the process step by step? I really which Raptor Computing Systems can be a bit more proactive, like doing videos similar to the Dell videos, in particular with Supermicro chassis since they claim some compatibility.


Talos II / Rackmount Server Chassis for Talos II
« on: February 12, 2020, 09:53:48 am »

I just purchased the Talos II board with 2xIBM POWER9 v2 CPU (8-Core) and 2U Heatsink Assemblies.  Looking for a rack mountable chassis. I had a look at, are there any other Rackmount Server Chassis folks used for Talos II?

I have been looking at variants of the Superchassis CSE-825TQ, such as:

  • SuperChassis 825TQ-R740LPB
  • SuperChassis 825TQ-600LPB

Has anyone tried these before? What are the power supply would you recommend for 2xIBM POWER9 v2 CPU (8-Core), with 8 SAS drives and 256GB memory? I only have an 15A/120V power outlet available.
