Abstract

Methods, systems, and apparatus, including computer program products, for discovering entities in a first portion of a data center network, examining information associated with the discovered entities to determine relationships that exist between pairs of entities in the first portion of the data center network, and generating a specification of the relationships that exist between pairs of entities in the first portion of the data center network based on results of the examining.

Claims

1. A computer-implemented method comprising:

discovering entities in a first portion of a data center network, the discovered entities including at least one storage end point, at least one server end point, and at least one server application instance, wherein discovering the entities comprises;

determining a presence of a plurality of end points in the first portion of the data center network, and

identifying at least one of said at least one storage end point and said at least one server end point based on communication with at least one of the plurality of end points; and

examining information associated with the discovered entities to determine relationships that exist between pairs of entities in the first portion of the data center network, wherein examining the information comprises;

examining meta information of a storage end point to identify a plurality of logical disks located in storage associated with the storage end point, and

examining data within each logical disk of the plurality to identify one or more server end points having access to that logical disk and one or more server application instances as storing data within that logical disk; and

generating a specification of the relationships that exist between pairs of entities in the first portion of the data center network based on results of the examining.

2. The computer-implemented method of claim 1, wherein discovering the entities comprises:

determining a presence of a server application instance on a first end point in the first portion of the data center network through an examination of one or more sub-entities of the first end point.

3. The computer-implemented method of claim 2, wherein discovering the entities comprises:

confirming the presence of the server application instance on the first end point through one or more server application handshakes.

4. The computer-implemented method of claim 1, wherein the discovered entities further include one or more of the following:

an authentication end point and a hypervisor platform.

5. The computer-implemented method of claim 1, further comprising:

storing the specification in a persistent storage portion of the data center network.

6. A machine-readable storage device that stores executable instructions to cause a machine to:

discover entities in a first portion of a data center network, the discovered entities including at least one storage end point, at least one server end point, and at least one server application instance, wherein discovering the entities comprises;

determining a presence of a plurality of end points in the first portion of the data center network, and

identifying at least one of said at least one storage end point and said at least one server end point based on communication with at least one of the plurality of end points; and

examine information associated with the discovered entities to determine relationships that exist between pairs of entities in the first portion of the data center network, wherein examining the information comprises;

examine meta information of a storage end point to identify a plurality of logical disks located in storage associated with the storage end point, and

examine data within each logical disk of the plurality to identify one or more server end points having access to that logical disk and one or more server application instances as storing data within that logical disk; and

generate a specification of the relationships that exist between pairs of entities in the first portion of the data center network based on results of the examining.

7. The machine-readable storage device of claim 6, wherein the instructions to cause the machine to discover the entities comprises instructions to:

determine a presence of a server application instance on a first end point in the first portion of the data center network through an examination of one or more sub-entities of the first end point.

8. The machine-readable storage device of claim 7, wherein the instructions to cause the machine to discover the entities comprises instructions to:

confirm the presence of the server application instance on the first end point through one or more server application handshakes.

9. The machine-readable storage device of claim 6, wherein the discovered entities further include one or more of the following:

an authentication end point and a hypervisor platform.

10. The machine-readable storage device of claim 6, wherein the stored executable instructions further comprise executable instructions to cause a machine to:

store the specification in a persistent storage portion of the data center network.
