Information Handling System Employing Unified Management Bus

Abstract

An information handling system includes a host including a central processing unit, a first management controller (MC) enabled to communicate with the host, and a network interface resource (NIR) in communication with the host and operable to enable the information handling system to communicate via an external network. The NIR includes a unified management module (UMM) operable to receive and route a local management packet, sent from the host, to the first management controller via a first unified management bus (UMB) and further operable to receive and route a remote management packet, sent from a remote resource via the external network, to the first management controller via the first UMB.

         21 . An information handling system comprising:
 a host including a central processing unit (CPU);   a first management controller (MC) configured to communicate with the host;   a second MC enabled to communicate with the host; and   a network interface resource (NIR) communicatively coupled to the host, the first MC and the second MC, the NIR configured to receive an Ethernet compliant management packet that includes destination information and determine from a management controller table whether the destination information corresponds to the first MC or the second MC.   
     
     
         22 . The information handling system of  claim 21 , wherein the NIR is further configured to route the management packet to the first MC via a first unified management bus (UMB) based on a determination that the destination information corresponds to the first MC. 
     
     
         23 . The information handling system of  claim 22 , wherein the NIR is further configured to format the management packet to comply with a transmission protocol suitable for transmission on the first UMB. 
     
     
         24 . The information handling system of  claim 21 , wherein the NIR is further configured to route the management packet to the second MC via a second unified management bus (UMB) based on a determination that the destination information corresponds to the second MC. 
     
     
         25 . The information handling system of  claim 24 , wherein the NIR is further configured to format the management packet to comply with a transmission protocol suitable for transmission on the second UMB. 
     
     
         26 . The information handling system of  claim 21 , wherein the management packet is a local management packet received from the host. 
     
     
         27 . The information handling system of  claim 21 , wherein the management packet is a remote management packet received from a remote resource via the external network. 
     
     
         28 . A non-transitory computer readable medium storing instructions for handling management traffic in an information handling system, the instructions, when executed by a processor configured to:
 receive an Ethernet compliant management packet at a network interface resource (NIR) communicatively coupled to a first management controller (MC) and a second MC;   detect destination information included in the management packet; and   determine from a management controller table whether the destination information corresponds to the first MC or the second MC.   
     
     
         29 . The non-transitory computer readable medium of  claim 28 , wherein the instructions are further configured to route the management packet to the first MC via a first unified management bus (UMB) based on a determination that the destination information corresponds to the first MC. 
     
     
         30 . The non-transitory computer readable medium of  claim 29 , wherein the instructions are further configured to format the management packet to comply with a transmission protocol suitable for transmission on the first UMB. 
     
     
         31 . The non-transitory computer readable medium of  claim 28 , wherein the instructions are further configured to route the management packet to the second MC via a second unified management bus (UMB) based on a determination that the destination information corresponds to the second MC. 
     
     
         32 . The non-transitory computer readable medium of  claim 31 , wherein the instructions are further configured to format the management packet to comply with a transmission protocol suitable for transmission on the second UMB. 
     
     
         33 . The non-transitory computer readable medium of  claim 28 , wherein the management packet is a local management packet received from the host. 
     
     
         34 . The non-transitory computer readable medium of  claim 28 , wherein the management packet is a remote management packet received from a remote resource via the external network. 
     
     
         35 . A method for handling management traffic in an information handling system comprising:
 receiving an Ethernet compliant management packet by a network interface resource (NIR) communicatively coupled to a first management controller (MC) and a second MC;   detecting destination information included in the management packet; and   determining from a management controller table whether the destination information corresponds to the first MC or the second MC.   
     
     
         36 . The method of  claim 35 , further comprising routing the management packet to the first MC via a first unified management bus (UMB) based on a determination that the destination information corresponds to the first MC. 
     
     
         37 . The method of  claim 36 , further comprising formatting the management packet to comply with a transmission protocol suitable for transmission on the first UMB. 
     
     
         38 . The method of  claim 35 , further comprising routing the management packet to the second MC via a second unified management bus (UMB) based on a determination that the destination information corresponds to the second MC. 
     
     
         39 . The method of  claim 38 , further comprising formatting the management packet to comply with a transmission protocol suitable for transmission on the second UMB. 
     
     
         40 . The method of  claim 35 , wherein the management packet is a local management packet received from the host. 
     
     
         41 . The method of  claim 35 , wherein the management packet is a remote management packet received from a remote resource via the external network.
