Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention generally relates to computer processing centers; and more specifically, the invention relates to methods and apparatus for physically locating individual computer systems in a processing center.

[0003] 2. Background Art

[0004] Many data processing centers or computer networks have a large number of individual computer or computer systems dispersed over a large area. For example, even a small center may have as many as forty or fifty computers spread out over a large office or office building. At times, it may be necessary to locate physically particular computers in such a center or network, for example, to add, test or replace equipment. Physically locating a particular system in a large data processing center can become both time consuming and expensive due to the large number of systems present and the large area over which the computers are located.

SUMMARY OF THE INVENTION

[0005] An object of this invention is to provide a method and system to locate physically individual computers in a data processing center.

[0006] Another object of the present invention is to enable a person to sit at a computer terminal, in a data processing center, and to issue a command to locate any other computer in the center.

[0007] A further object of the invention is to provide procedures for computers in a data processing center that enable the computers to issue, and to monitor for, commands to locate the computers.

[0008] These and other objectives are attained with a method and apparatus for locating an un-located asset in a computer center including a plurality of assets connected together by a network. The method comprises the steps of a host asset of the computer center, obtaining an address for the un-located asset; and sending a command from the host asset to the un-located asset, through the computer center network, for the un-located asset to produce a signal for physically locating the un-located asset. Preferably, the method further comprises the steps of sending a request from the host asset to the un-located asset, through the computer center network, for the un-located asset to confirm that the un-located asset is in the computer center; and in response to receipt of said request, the un-located asset sending a signal to the host asset to confirm that the un-located asset is in the computer center.

[0009] More specifically, in the preferred implementation of the invention, an IP “SQUAWK” command is issued from any computer asset or system in the computer center or network to the IP address of the un-located computer asset system. Preferably, the code needed to implement the SQUAWK command is contained in a patch that is loaded on the computer systems during initial system code load. This patch runs as a daemon in the background of all the systems in the data processing center. Also, preferably, the code for this command is written in a high level, language, such as JAVA, to eliminate the need for porting the code to different host manufacture types.

[0010] Further benefits and advantages of the invention will become apparent from a consideration of the following detailed description, given with reference to the accompanying drawings, which specify and show preferred embodiments of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] FIG. 1 shows a data processing center 10 comprising a multitude of computer systems 12 connected together to form a local area network (LAN) 14. Any suitable computer systems may be used in center 10; and for example, as represented in FIG. 1, each system may include a central processing unit, a monitor, and input means such as a keyboard and a mouse. Other specific types of computers or computer systems may be used, however, and, for example, conventional personal computers, laptop computers, and work stations may be used. Also, the computer systems 12 may be connected together in any appropriate way to form LAN. Many suitable techniques for doing this are well known in the art.

[0015] It is not uncommon, in today's world, for the individual computer systems of a data processing center to be dispersed over a significant area, such a large office or an office building. Moreover, because of the mobile nature of many state of the art computers, the actual physical locations of specific computers of center may change from time to time. Because of these factors and others, a network administrator, or other individuals, may not know the exact location of particular computers in center. Such a computer is referred to as an un-located asset or un-located computer. For example, computer system referenced at 16 in FIG. 1 is considered to be un-located. In accordance with the present invention, at least one, and preferably all, of the computer systems of center 10 are provided with a procedure to locate an un-located asset in the center. Generally, this is done by an IP “SQUAWK” command issued from any computer system in the network to the IP address of the un-located computer system. Preferably, the code needed to implement the SQUAWK command is contained in a patch that is loaded on the computer systems during initial system code load. This patch runs as a daemon in the background of all the systems in the data processing center 10. Also, preferably, the code for this command is written in a high level, language, such as JAVA, to eliminate the need for porting the code to different host manufacture types.

[0016] For example, if one wanted to locate the host at IP address 9.115.63.69, an operator would issue a SQUAWK 9.115.63.69 command from any other computer in the network. The command is translated into an IP packet containing the command code and the address of the system to be located. This packet is then broadcast to all hosts and the IP address compared at each host; and when a match is found at the un-located host, that un-located host will, for example, begin beeping its speaker, thus allowing the un-located system to be easily found. Alternately, as another example, a blinking light could be used to identify the location of the un-located host.

[0017] FIG. 2 is flowchart of a preferred procedure that may be used by any computer of center 10 to locate another computer of the center. At step 100 the procedure is started; and at step 102 the searching computer issues a prompt asking for the address of the un-located computer. For example, this prompt may be in the form of a message or dialog box shown on the computer monitor; and, in response, the user supplies the address of the un-located computer. After the searching computer is given this address, the searching computer, at step 104, sends a message to the un-located system asking that system to confirm that it is in the data processing center 10. This may be done, for instance, by a well known procedure referred to as a ping command.

[0018] At step 106, the searching computer determines, on the basis of the response to the message sent at step 104, whether the un-located system is on the data processing center 10. If the searching computer determines that the un-located computer is not in the center, the procedure of FIG. 2 goes to step 108, discussed below. If, however, the searching computer determines that the un-located computer is in the data processing center 10, then the procedure moves on to step 110, where a message is sent to the un-located computer to generate some signal or response that may be used to identify its physical location. For example, as mentioned above, the un-located computer may be asked to produce an audible signal by beeping a speaker that is part of the computer system. Other types of signals may also be used, however, such as a blinking light.

[0019] After step 110, the searching system waits for a period of time, referred to as timeout, for a response, as represented by steps 112 and 114. Preferably, the length of this time-out is determined before the procedure begins a particular cycle. Also, preferably the length of the time-out is adjustable, and for example, may be adjusted by the system user. If a response is received within the time-out period, then preferably the actual physical location of that computer is identified and entered in a database, as represented by step 116. After this is done, the procedure goes to step 118, and the searching system determines, in any suitable manner, whether any more computer systems are to be located. If more systems are to be located, the procedure returns to step 102; however, if no more systems are to be located, the procedure is exited at step 120.

[0020] If at step 106, the searching computer determines that the un-located system is not in the center, or if at step 114, a response is not received within the time-out, then the procedure goes to step 108. At this step, the user is notified that the un-located system is not active. After step 108, the procedure moves on to step 118 and proceeds from there as discussed above.

[0021] FIG. 3 is a flow chart of a preferred procedure that may be used by each of the computers 12 of center 10 to monitor for and to respond to the searching procedure of FIG. 2. At step 200, the computer is started, and step 202 represents the start of an application to listen for the alert/locate message sent at step 110 of FIG. 2. Any suitable routine may be used to listen for this message. The computer continuously listens for this message, as represented by step 204, and when a message is received, the procedure goes to steps 206 and 210.

[0022] At step 206, the computer displays a dialog box prompting the user of that computer to input information. This information, for example, may identify the specific location of the computer, such as the building and room in which the computer is located. Other information may also be prompted such as the computer's owner and serial no. At step 210, the procedure causes the computer to generate a signal or response that may be used to locate physically the computer. For example, a speaker may start beeping, although other signals can also be used.

[0023] At step 212 of the procedure, the user provides the information requested in the dialog box, and closes that box; and at step 214, the provided information is sent to the searching computer. After a given period of time, as represented by step 216, the computer stops producing the signal or message started at step 210; and from step 216, the computer returns to step 204, and the procedure again monitors for an alert/locate message.

[0024] While it is apparent that the invention herein disclosed is well calculated to fulfill the objects stated above, it will be appreciated that numerous modifications and embodiments may be devised by those skilled in the art, and it is intended that the appended claims cover all such modifications and embodiments as fall within the true spirit and scope of the present invention.
