Server computer and a method for accessing resources from virtual machines of a server computer via a fibre channel

A computer system having an operating system and a resource comprising:

• a server computer including an adapter component for receiving of a request from the operating system and having an access rights administration module for assigning of access rights to the operating system and for granting of the request in case of compliance with the corresponding access rights, and a fibre channel module for sending the request to the resource via a fibre;
• a fibre channel switchcoupled to the server computer;
• a Storage Area Network coupled to the fibre channel switch;
• and
• a fibre channel resource controller coupled to the resource and to the Storage Area Network.

A method for accessing a resource from a virtual machine of a plurality of virtual machines being provided by a server computer, the method comprising the steps of:

• sending a request from the virtual machine together with a request identifier to an adapter component of the server computer;
• transforming the identifier into an unequivocal identifier of the request;
• transmitting the request with the unequivocal identifier over a fibre channel to the resource;
• receiving a response from the resource with an unequivocal identifier of the response;
• and
• forwarding the response to the corresponding virtual machine.

A computer program product for accessing a resource from a virtual machine of a plurality of virtual machines being provided by a server computer, said program product comprising:

• A computer readable medium having recorded thereon computer readable program code for performing the method comprising:
• sending a request from the virtual machine together with a request identifier to an adapter component of the server computer;
• transforming the identifier into an unequivocal identifier of the request;
• transmitting the request with the unequivocal identifier over a fibre channel to the resource;
• receiving a response from the resource with an unequivocal identifier of the response;
• and
• forwarding the response to the corresponding virtual machine.
