Hello everyone,
Besides supplying the SAS backplane with firmware updates, which I'll assume is through the motherboard firmware updates, is there any other reason to have the backplane connected to the motherboard through the I²C/HSBP connector?
Thanks
Ray

Hello RSump1,
Thank you for joining the community
The purpose of the I2C HSBP cable is for management mainly. If you keep it disconnected you will be missing the its signal and won't be able to see it in the BMC management console not receive the IPMI traps. Yo can look for more details in this document: https://www.intel.com/content/dam/support/us/en/documents/server-products/server-boards/S2600WF_TPS.pdf#page=96
Hope it helps

Hello Jose,
Thank you for the reference to the document, though I'm sure I am missing something. With the cable not connected, I know I will not get any firmware updates to the backplane, but other than that, will I miss out on any functionality? Will the backplane still function correctly? Will I still be able to hotswap a drive if necessary?
Thanks
Ray

Hello RSump1
The overall functionality of the hot swapable backplane will be the same with the I2C cable disconnected, it is just that you will loose management capabilities. It will allow you to hot swap any HDD if needed of course.

Thank you for your reply Jose, last question concerning the cable, besides "transmitting" firmware updates to the backplane when a motherboard firmware update is done, what other management functions will I miss out on?
Thanks!

Hello RSump1
By leaving the I2C cable disconnected you will loose the capability to see the backplane health status on the BMC management console. Besides that I have to confirm if the back plane status will be missing in the RAID management software like the Intel Raid Web Console 3.

Hello RSump1,
Let me add this info to our previous conversation. The BMC generates SEL events by monitoring registers on the HSBP microcontroller for a drive presence, fault, and RAID rebuild progress. It's recommended to have the I2C, so the you can verify any events in the BMC/RWC3.
For further details, it would be important to know if you have a hardware RAID controller, ESRT2, model of the chassis, or server system, and type of RAID and disks.
