Subject: [Openhpi-devel] Some doubts

Hi all,
I've got some doubts,
1. this one is regarding the terminology - Is the BMC (Base board =
Management Controller) and Shelf Manager one and the same. As of my =
understanding BMC is an IPMI term and Shelf manager corresponds to ATCA.
>>I'm not sure what you mean, but I will explain the role of both =
devices:
>>BMC is typically found in non-bladed systems and is the dedicated =
management processor which holds (and is required by the IPMI spec to be =
at address 20h)the IPMI data and is responsible for IPMI functionality.
>>IPMC: IPM Controller: could be a BMC or could be a satellite =
controller as well.  It's simply a device that implements the required =
interfaces and functionality according to the spec.
>>ShelfManager: ATCA term for the entity in the chassis responsible for =
all management aspects.  It's an IPMI compliant entity/device and in =
this context similar to a BMC (in fact it's required to respond to the =
same 20h address) but in a bladed environment.

2. Regarding the output of the rpt command on hpi_shell
OpenHPI> rpt
(001):IPM Sentry BMC:{S|RDR|ELOG|INV|FRU|HS|RES}
(002):Shelf EEPROM 1:{S|RDR|INV|FRU|HS|RES}
(003):Shelf EEPROM 2:{S|RDR|INV|FRU|HS|RES}
(004):ShMM-300:{S|RDR|INV|RST|FRU|HS|RES}
(006):IPM Controller:{S|RDR|INV|RST|FRU|HS|RES}
(007):IPM Controller:{S|RDR|INV|RST|FRU|HS|RES}

what are the entries 2 and 3 correspond to (EEPROM 1 & 2)??

How are the entries 1 and 4 different?? According to my understanding =
both should correspond to the Shelfmanager/BMC of the system. I get the =
text string "=A0 Content: TEXT: ENGLISH: IPM Sentry Shelf Manager =
(len=3D24)"=A0 in the "PRODUCT_NAME" field of the=A0 showinv command for =
resources 1 and 4.

>>In any IPMI system, but especially in ATCA, you will have multiple IPM =
Controllers.  The BMC term references the mandatory controller at =
address 20h. The rest are satellite controllers (think of them as child =
controllers off of the central BMC).

So in an ATCA system, the Shelf Manager(s) will have a physical address =
of maybe 10h but will also need to respond to virtual address 20h.
The blades in the chassis must have IPM Controllers on board to handle =
local IPMI functions, forward events to the "BMC/ShelfManager" and =
perform other functions per the spec.  That's what you see there.

I hope I explained it well.  Let me know if you have any other =
questions.
