Abstract

Establishing connectivity of nodes. A first data is received at a resource manager from a first base management controller (BMC) associated with a first node, wherein the resource manager is associated with a server computer system. A second data is received at the resource manager from a second BMC associated with a second node. A classification of the first node and the second node are determined and a compatibility of the first node with the second node based on the first data and the second. A topology is generated, at the resource manager, of the first node and the second node.

Claims

1. A method for establishing connectivity of nodes, said method comprising:

receiving a first data at a resource manager from a first base management controller (BMC) associated with a first node, wherein said resource manager is associated with a server computer system;

receiving a second data at said resource manager from a second BMC associated with a second node;

determining a classification of said first node and said second node and a compatibility of said first node with said second node based on said first data and said second; and

generating a topology, at said resource manager, of said first node and said second node.

2. The method of claim 1 wherein said first node and said second node each comprise an optical transceiver and are connected via an optical connection.

3. The method of claim 1 wherein said first node and said second node each comprise a main component and said receiving said first data and said receiving said second data occur before said main component of said first node and said second node boot up.

4. The method of claim 1, further comprising:

sending said first node and said second node authorization to boot up a main component, wherein said authorization is based on said compatibility.

5. The method of claim 1, further comprising:

providing said classification of said first node and said second node, said compatibility, and said topology to another entity.

6. The method of claim 1, further comprising:

determining a compatibility of a main component of said first node with a power source.

13. The system of claim 1 wherein said first main component and said second main component are selected from the group of components consisting of:

a processor, a network interface card, a switch, and a blade server.

14. The system of claim 1 wherein said first node and said second node each comprise an optical transceiver and are connected via an optical connection.

15. The system of claim 1 wherein said resource manager is further configured to receive said first data and said second data before said first main component and said second main component are booted up.

7. A computer-usable storage medium having instructions embodied therein that when executed cause a computer system to perform a method for establishing connectivity of nodes, said method comprising:

receiving a first data at a resource manager from a first base management controller (BMC) associated with a first node, wherein said resource manager is associated with a server computer system;

receiving a second data at said resource manager from a second BMC associated with a second node;

determining a classification of said first node and said second node and a compatibility of said first node with said second node based on said first data and said second; and

generating a topology, at said resource manager, of said first node and said second node.

8. The computer-usable storage medium of claim 7 wherein said first node and said second node each comprise an optical transceiver and are connected via an optical connection.

9. The computer-usable storage medium of claim 7 wherein said first node and said second node each comprise a main component and said receiving said first data and said receiving said second data occur before said main component of said first node and said second node boot up.

10. The computer-usable storage medium of claim 7, further comprising:

sending said first node and said second node authorization to boot up a main component, wherein said authorization is based on said compatibility.

11. The computer-usable storage medium of claim 7, further comprising:

providing said classification of said first node and said second node, said compatibility, and said topology to another entity.

12. A system for establishing connectivity of nodes, said system comprising:

a first node comprising a first base management controller (BMC), a first memory with a first data, and a first main component;

a second node comprising a second BMC, with a second memory with a second data and a second main component; and

a resource manager for receiving said first data and said second data from said first BMC and said second BMC for determining a classification of said first node and said second node and a compatibility of said first node with said second node based on said first data and said second and for generating a topology of said first node and said second node.
