Abstract

In a data center or server room, it’s quite difficult to find the location of a physical server. The conventional solution combines hardware and software to visualize the physical location in a blade chassis like AMM. This disclosure describes a pure SW solution to define a relation of its neighbors and/or in a rack. We use a simple setup procedure and network UDP protocol to build a logical system location relationship. In this disclosure, no hardware expense is needed.

Server locating mechanism in a rack


1) Background

- In a data center or server room, it's quite difficult to find the location of a physical server.

- Current solutions combines HW and SW to visualize the physical location in a Rack.


2) Summary of invention

- We use a network UDP protocol to build a logical server location relationship.

- This relationship can be visualized in a utility.

- Using our technology, one can easily define a relation of its neighbors and/or in a rack.

- We propose a pure SW solution that can apply on rack server as well.

- Our idea costs no hardware expense.


3) Description

3.1)Our disclosure to achieve locating servers in rack

- Simple setup procedure.

- Network negotiation.

3.2) Simple Setup Procedure

- One time effort when a new server is going to be setup in the rack.

Example : 5 servers in a rack

3.3) Network negotiation

- UPD protocol:

Define Packet.

Define Finite State Machine.


- Each server will install the same utility to indentify their physical location.


- Three examples for different cases.

3.4) Packet formation

3.5) OpCodes

3.6) Finite State Machine

3.7) Flow - move in

Example : 5 servers in a rack and second server boot

3.8) Flow polling

Example : 5 servers in a rack and first server acting as a host to do the polling

3.9) Flow - polling with ownership transition

Example : 5 servers in a rack and first server power down / moved out
