## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to inventory management in a data center and more particularly to locating physical resources in a data center.
2. Description of the Related Art
A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems. The typical data center generally includes not only a multiplicity of servers, both stand alone and rackmount, but also communication switching devices, redundant or backup power supplies, environmental controls including air conditioning and fire suppression and security devices. Oftentimes, different sets of servers and associated switches are stored in cabinets within the data center or on racks in the data center, with those cabinets or racks organized in rows just as may be the case with bookshelves in a library.
In any datacenter environment, it is necessary to locate a particular physical hardware device for several reasons—for example, to address a fault or other condition accessible only through direct physical access to the hardware device. However, the location of a hardware device in a datacenter can differ from a specific rack or cabinet number in a particular location, to a slot within a chassis located in a specific rack or cabinet in a particular location. Current solutions address the complexity of locating individual hardware components in the data center through the utilization of several technologies such as universal product codes (UPC) and radiofrequency identification (RFID) tags. These methods require the personnel to carry a device to read the UPC or RFID values, as they are not generally human-readable. Methods such as RFID also suffer from the problem of having multiple responses to a local read, since many tags will respond to a read action from the user. UPC suffers from the requirement of having to scan each code individually, which requires the personnel to scan multiple systems to find the specific one being sought.
As a more general method of locating elements in the data center without a specific identification tag, visual indicators, such as LEDs may be illuminated to draw attention to components in need of service. Even still, these lights may be lost in the sea of other status and activity LEDs that are commonly present on the front and back panels of a data center device.
BRIEF SUMMARY OF THE INVENTION
Embodiments of the present invention address deficiencies of the art in respect to device location in a data center and provide a novel and non-obvious method, system and computer program product for dynamic activation of service indicators based upon service personnel proximity. In an embodiment of the invention, a method for dynamic activation of service indicators based upon service personnel proximity is provided. The method includes receiving at an enclosure of different hardware devices in a data center, a message for personnel proximity based activation of a service indicator lamp and activating a presence sensor in response to receiving the message. The method also includes responding to presence sensing an individual by the presence sensor by activating the service indicator lamp of the enclosure.
In one aspect of the embodiment, the individual is authenticated responsive to presence sensing the individual and the message text of the message is displayed in a management console of the enclosure only if the individual authenticates. In another aspect of the embodiment, the message text of the message is displayed in a management console of the enclosure responsive to presence sensing the individual by the presence sensor.
In another embodiment of the invention, a data processing system is configured for dynamic activation of service indicators based upon service personnel proximity. The system includes an enclosure enclosing different hardware devices in a data center and a management console managing the enclosure. The system also includes a service indicator lamp coupled to the enclosure and a presence sensor disposed in the enclosure.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein:
FIG. 1 is a pictorial illustration of a process for dynamic activation of service indicators based upon service personnel proximity;
FIG. 2 is a schematic illustration of a data processing system configured for dynamic activation of service indicators based upon service personnel proximity; and,
FIG. 3 is a flow chart illustrating a process for dynamic activation of service indicators based upon service personnel proximity.



DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the invention provide for dynamic activation of service indicators based upon service personnel proximity. In accordance with an embodiment of the invention, a hardware device in a data center can be co-located in a same enclosure as a wireless proximity detection device including that of a Wi-Fi access point, or an infrared sensor. Responsive to the wireless proximity detection device detecting a presence of a person, a visual indicator such as a service LED can be activated at the enclosure. Further, a console display can provide information pertaining to a condition of the hardware device. Optionally, the person can be authenticated by the enclosure and only an authorized person can be granted access to the console display. Alternatively, only an authorized person can be provided additional detail pertaining to the condition.
In further illustration, FIG. 1 pictorially shows a process for dynamic activation of service indicators based upon service personnel proximity. As shown in FIG. 1, an enclosure 100 such as a rack or cabinet in a data center can enclose different servers 110. The enclosure 100 further can include a console display 130 configured to manage the operation of the servers 110 in the enclosure including power and data communications. Of note, a presence sensor 120 also can be included. The presence sensor 120 can include an infrared sensor enabled to detect movement proximate to the presence sensor 120, or a Wi-Fi access point with which the proximity of a wireless device of an end user can be determined by way of the device associating with the Wi-Fi access points.
Dynamic activation logic 150 can be coupled both to the presence sensor 120 and also the console display 130. The dynamic activation logic 150 can respond to a request to enable the presence sensor 120 by enabling the presence sensor 120 and, in response to the presence sensor 120 detecting the presence of an individual 160, the dynamic activation logic 150 can illuminate a service lamp 140A present in the enclosure 100 so as to alert the individual as to the physical location of the enclosure 100. Additionally, the dynamic activation logic 150 can deactivate other lamps 140B present in the enclosure 100 so as to avoid cluttering a display of lights in the enclosure 100 and to allow the service lamp 140A to be clearly visible to the individual 160. Yet further, the dynamic activation logic 150 can deactivate other lamps 140B present not only in the enclosure 100 but also lamps present in adjacent enclosures.
Optionally, to the extent that the dynamic activation logic 150 can authenticate the individual 160, the dynamic activation logic 150 can provide a message to the console display 130 so as to provide the individual 160 with information regarding the enclosure 100 or one or more of the servers 110 in the enclosure 100. For example, the dynamic activation logic 150 may perform an additional authentication step of providing the individual 160 through the console display 130 with a challenge-response, such as a password prompt to grant full access to the console display 130.
The process described in connection with FIG. 1 can be implemented in a data processing system. In more particular illustration, FIG. 2 schematically shows a data processing system configured for dynamic activation of service indicators based upon service personnel proximity. The system can include a host computer 210 with memory and at least one processor, the host computer 210 being communicatively coupled to different hardware devices 230 in common enclosure (not shown) over a computer communications network 220. The host computer 210 also can include a set of lamps 260 including a service indicator configured upon activation to illuminate to the exclusion of others of the lamps 260.
A management console 240 can execute in the memory of the host computer 210. The management console 240 can be configured to direct management operations of the different hardware devices 230 and the enclosure (not shown). The management console 240 can be coupled to a presence sensor 250 configured to sense the presence of an individual. Examples include an infrared sensor, or even a Wi-Fi access point to become associated with a Wi-Fi enabled device so as to infer the proximity of an individual associated with the Wi-Fi enabled device. Finally, a service indicator activation module 300 can be coupled to the management console and the presence sensor 250 and can execute in the memory of the host computer 210.
The service indicator activation module 300 can include program code that when executed in the memory of the host computer 210 is enabled to respond to a request to enable the presence sensor 250 by enabling the presence sensor 250 and, in response to the presence sensor 250 detecting the presence of an individual, to direct the illumination of the service indicator amongst the lamps 260 and the deactivation of others of the lamps 260 so as to alert the individual as to the physical location of the enclosure and the particular one of the devices 230 in the enclosure in need of servicing. Optionally, the program code of the service indictor activation module 300 can be enabled to authenticate the individual and provide a message to the management console 240 so as to provide the individual with information regarding the enclosure or one or more of the hardware devices 230 in the enclosure.
In even yet further illustration of the operation of the service indicator activation module 300, FIG. 3 is a flow chart illustrating a process for dynamic activation of service indicators based upon service personnel proximity. Beginning in block 310, a device or an enclosure containing the device can be selected and in block 320, a message can be sent to the device (or enclosure) requesting activation of the service indicator lamp along with pertinent message text to be displayed in a management console of the enclosure. Also, as part of the directive can be sent to the device to activate the service indicator lamp, in block 320 a directive can be sent to the device to de-activate all other lamps of the device. In block 330, in response to the message, a presence sensor can begin sensing for the presence of an individual, either through infrared detection of proximate objects in motion, or by Wi-Fi association of a Wi-Fi enabled device with a wireless access point of the enclosure.
In decision block 340, if the individual is detected proximate to the enclosure, in block 350 the individual can be authenticated. In decision block 360, if authenticated, in block 370 the service indicator of the enclosure can be illuminated and the message text displayed in the management console while other lamps of the enclosure can be darkened or completely deactivated. Optionally, the individual also can be automatically granted access to the management console once authenticated. As a further option, access to the management console can be limited to specific service activities based upon the identity of the individual and the proximity of the individual to the management console. For example, the management console may permit the individual to access one set of operations, however in a specific service case, the set of operations may be reduced to only a subset of critical operations depending upon the state of the device leading to the event requiring servicing of the device. Thereafter, the process can end in block 380.
