Re: Core I/O card and GSP functions

The GSP (guardian service processor) is taking care of your system, provides logs, remote console connections etc.

The core I/O provides a console device and most of times the core LAN and SCSI connections for the server.

Hope this helps!

Re: Core I/O card and GSP functions

Not sure what exactly you want to know.

What server model do you have?

Hope this helps!

Re: Core I/O card and GSP functions

Hi,

There is no rigorous definition as it means somewhat different things on different models. On some models there is literally a separate board labeled "Core I/O" so whatever is on that card is, by definition, Core I/O. In other cases, the core i/o functions are integrated with the systemboard. In general, it means those I/O capabilities/ports that are included with the base system as opposed to optional i/o boards.

Mosts systems have this separate and include GSP/MP with it, and a LAN / SCSI. Hence Core Input / Output.

Re: Core I/O card and GSP functions


On most servers the core I/O card is a special card containing a LAN device and a console device. But it depends on the specific model - they are all different ...

Core I/O is basically that : Core

the minimum needs to systems to come up.

What is the minimum. 1 x Serial for standard output, input and error.

The service processor in HP servers is sometimes called the Management Processor (MP) and sometimes the Guardian Service Processor (GSP).

Regardless of the name, the service processor in these servers provides approximately the same features and performs essentially the same role.

Throughout this document the term "service processor" refers to both the MP and GSP service processors.

Check belwo link for GSP/MP ,
