Description:
TECHNICAL HELD 
       [0001]    The present invention relates generally to techniques for providing processing services within a computing system, and more particularly, to techniques for providing a virtual, unique system identity. 
       BACKGROUND 
       [0002]    Computer systems, such as servers, may have a number of different specifications, configurations, pricing methods, and licensing techniques, which may depend on business methods implemented by a vendor or an information technology company. Customers of information technology companies and vendors have a wide variety of needs, and providing options and customizable configurations allows a customer to tailor a computer system, billing method, and licensing technique to his individual needs. 
         [0003]    Computer systems sold or licensed by vendors or information technology companies are intended to perform only the tasks that have been negotiated, and certain licenses and systems management routines confirm that only licensed hardware is being implemented and only authorized tasks are being performed by the computer system. As a specific example, a piece of hardware may have a unique serial number, and the computer system confirms that the piece of hardware has the expected, licensed serial number before performing computing tasks. If an unlicensed piece of hardware is detected, the computer system will not perform any computing tasks. If a licensed piece of hardware fails, it must be replaced with a new piece of hardware that also has a unique serial number. So, not only does the hardware have to be replaced, but the system will not compute until a new license is received for the replacement piece of hardware. Also, companies billing the customer for the computer system must update their records to reflect the change in licensing and serial numbers. Such a replacement method is a tedious process for the customer and the information systems company. A system of this nature is described in U.S. patent application Ser. No. 11/647,683, entitled “System and Method for Providing a Mechanism to Virtualize a Perpetual, Unique System Identity on a Partitioned Computer System,” and filed Dec. 29, 2006. 
         [0004]    Beyond system maintenance, the needs of a customer may change over time, and a computer system that met or exceeded customer needs initially may become insufficient or cease to be economical. As an example, a customer may initially find that a metering method of billing provides cost savings over a capacity on demand system of billing. As the customer grows, expands, or changes business models, the customer may find that the capacity on demand method of billing is more economical than the metering method. Given the nature of the licensing, the computer system may be licensed for capacity on demand or programmed to perform only metering. Changing a system&#39;s billing method may be accompanied with a change the name of the system, which may require a lengthy update. Currently the name of the system and the system product line is part of the firmware build. Thus, if the system name is to be changed, the firmware must be updated, and updating the firmware may require a system reboot, which may interrupt critical computer system tasks, delete important data, and require a significant period of time. 
         [0005]    A computer system licensed by a customer may require a name change and a corresponding product line change for a variety of reasons. In one example, a marketing department of the information systems company may change the system names or the product line of a system. Also, responding to customer needs may require the changing of a name of a system. In either situation, a firmware update would be required to the disappointment of the customer. 
         [0006]    Thus, a method of providing a new system name and product line to a computer system without requiring a firmware update or even a reboot of the computer system is desired. 
       SUMMARY 
       [0007]    The systems and methods described herein attempt to overcome the drawbacks discussed above by providing a method for changing a system name of a computer system, a product line of the computer system, a business model of the computer system, and number of visible processors of the computer system without requiring a firmware update. The system name may be changed by providing a virtual system name, which is provided by an external key generator unit controlled by an information system&#39;s company. 
         [0008]    In one embodiment, a method for providing a system name of a computer system, comprises generating a system ID key based on a system type of the computer system using an external key generator module; installing the system ID key on the computer system in an active operating state by extracting the system name from the system ID key; updating operating system structures for immediate use of the system name; writing a machine name index into halt/load parameters that are implemented by the computer system for subsequent restarts of the computer system after suspending the computer system, wherein the machine name index identifies a location of the system name in a system registry; and writing the system name into the system registry from the system ID key. 
         [0009]    In another embodiment, a method for providing an immediate uninterrupted installation of a unique system identity, a system name, a product line, and a number of visible processors of a computer system, comprises generating a system ID key based on a system type of the computer system, a number of processors enabled in the computer system, and a product line of the computer system; installing the system ID key to the computer system in an active operating state by extracting the unique system identity, the system name, the product line, and the number of visible processors from the system ID key; updating operating system structures for immediate use of the unique system identity, system name, product tine, and pool of visible processors; writing a machine name index into halt/load parameters that are implemented by the computer system for subsequent restarts of the computer system after suspending the computer system, wherein the machine name index identifies a location of the system name, product tine, and number of visible processors in a system registry; and writing the system name, product line, and number of visible processors into the system registry from the system ID key. 
         [0010]    In another embodiment, a computer program product for generating an external key comprising a non-transient computer readable medium having a computer readable program, wherein the computer readable program including a key generator module that when executed on a processor causes a computer to: generate a system ID key to be installed on the computer based on a system type of the computer, a number of processors enabled in the computer, and a product line of the computer, wherein the system ID key provides the computer a system name, a product line, and a number of visible processors.

     DETAILED DESCRIPTION 
       [0017]    Reference will now be made in detail to the preferred embodiments, examples of which are illustrated in the accompanying drawings. Turning now to the drawings, in which like numerals represent like (but not necessarily identical) elements throughout the figures, exemplary embodiments of the present invention are described in detail.  FIG. 1  illustrates a computer system implementing a system ID key according to an exemplary embodiment. 
         [0018]    Referring to  FIG. 1 , a computer system  100  includes a plurality of processors  101 ,  102 ,  103 ,  104 , a block of memory  110 , an input/output (I/O) interface  120 , a network interface  130 , and a data bus  140 . The plurality of processors  101 ,  102 ,  103 ,  104 , the memory block  110 , the I/O interface  120 , the network interface  130  may all communicate with one another through the data bus  140 . While the elements listed above are illustrated in  FIG. 1 , it is to be understood that the computer system  100  may include many more computing components, such as a graphics module, a hard drive, a CD-ROM drive, DVD-ROM drive, tape drive, audio modules, universal serial bus (USB) ports, power supplies, cooling devices, heat sinks, or any other components that may be included in a computing device. Also, while the computing device  100  illustrates one partition and one cell, the computing device may include more than one partition or more than one cell, which may be running various operating systems. If additional cells and/or partitions are included, a server control unit may further be included to provide supervisory control over the entire computing system  100 . The size and configuration of the computing system  100  may increase or decrease depending on computing model, billing method, or customer need. 
         [0019]    The plurality of processors  101 ,  102 ,  103 ,  104  included in the computer system  100  illustrate an example of a multi-processor system. Each processor may perform a different task, and each processor may be differently configured to accommodate specific tasks. Alternatively, all of the processors  101 ,  102 ,  103 ,  104  may be constructed in the same manner, and one or more of the processors  101 ,  102 ,  103 ,  104  may be a spare processor included for redundancy. Additionally, one or more of the processors  101 ,  102 ,  103 ,  104  may be included to provide supervisory control over the other processors  101 ,  102 ,  103 ,  104 . While four processors  101 ,  102 ,  103 ,  104  are illustrated in  FIG. 1 , the exemplary embodiments may be applied to any multi-processor system and as well as to a single processor system 
         [0020]    The memory block  110  may include any computer storage medium, either volatile or non-volatile, removable or non-removable, such as FLASH, RAM, ROM, EEPROM, or any other storage medium that is configured to store information in any method or technology for information storage. The memory block  110  is configured to store computer readable information, such as computer readable instructions and data. The memory block  110  may be implemented to store program code to direct the processors  101 ,  102 ,  103 ,  104  to process information and requests to or from other computing systems connected to the computer system  100  in any manner, such as through the network interface  131 ). 
         [0021]    The network interface  130  provides a network connection means and network protocols useful for sending and receiving information from and to other computer systems connected to the computer system  100 . The network interface  130  may be connected to a network of any type, such as a local area network (LAN), a wide area network (WAN), or a wireless local area network (WLAN). The network interface  130  may communicate with other computer systems on the network through network protocols, such as TCP/IP, FTP, SSH, or any other network protocol. In addition, the network interface  130  may be connected to a network through any means including wireless means, such as Bluetooth, IEEE 802.11, and infrared, or wired means, such as Ethernet, firewire, and coaxial. 
         [0022]    Peripheral devices  122  and  124  are connected to the I/O interface  120 , and the peripheral devices  122  and  124  allow the computer system to receive inputs from a user and output data and information to the user. The peripheral devices may include a mouse, a keyboard, a monitor, a printer, a scanner, a touch screen, buttons, or any other peripheral device useful for receiving data from a user and outputting data to a user. 
         [0023]    The computer system  100  further includes a system key  150  that is provided by the external key generator module  160 . The external key generator  160  may be operated by an information systems company or vendor that provided the computer system  100 . The external key generator  160  may remain in the possession of the information systems company and may be used for system changes, upgrades, and downgrades. The external key generator module  160  installs the system key  150  on the computer system  100  for a plurality of reasons including, providing the system with an identity, setting a system capacity, turning on and off system components, and providing unique serial numbers for licensing. Each of these specific reasons will be discussed in detail below, but the system key  150  may perform additional tasks when installed on the system  100 . 
         [0024]    As one example of the features of the system key  150 , when the system  100  is manufactured, the hardware components, such as the processors  101 ,  102 ,  103 ,  104  or the memory  110 , are not branded with a serial number. Instead, the system key  150  is installed on a basic computer system with a running operating system to provide a virtual serial number for the hardware components. Thus, if a component needs to be replaced, the new component may be installed and given the same virtual serial number as the part that the new component replaced. Rather than changing the entire licensing paradigm, a new system ID key can be installed to account for the new piece of equipment. By providing the original manufacturing (virtual) serial number to the hardware, the computer system  100  retains all of its installed licenses, even though new hardware has been included. 
         [0025]    As another example, when a new system  100  is manufactured, it may have certain characteristics such as four processors  101 ,  102 ,  103 ,  104 , a certain amount of memory, etc. A customer may not have need for all of the computing power included in the system  100 , and thus, the information system company may provide a customer with a base system  100  and disable some hardware and computing resources to meet the customer&#39;s needs rather than manufacture a unique system with the customer&#39;s desired hardware. The system key  150  is the means by which hardware components are enabled or disabled. A first system key may turn on 50% of the processors ( 101  and  102 ) included in the system  100 . Meanwhile, a second key may enable all of the processors ( 101 ,  102 ,  103 ,  104 ) included in the system  100 . Furthermore, the first system key may be associated with a first computer model, and the second system key may be associated with a second computer model. Thus, by simply installing a new system key  150  into the operating system of the computer system  100 , the configuration of the computer system changes, the model of the computer system  100  may change, and the name of the machine may change as well. By disabling or enabling components of a base system  100 , the information system company may provide financial savings to the customer while saving money itself because all machines, regardless of customer selected configuration, may be manufactured with the same components and by the same process. Further, as the needs of a customer change, the information systems company may simply enable disabled hardware components using a new system key  150  for an instant upgrade that does not require the customer to buy additional hardware or configure and deploy a new system. 
         [0026]    When a system key  150  is installed, the system does not have to be paused or rebooted. Instead, the machine type and name information is immediately applied using the system ID key and updating operating system tables and notifying the systems management  170  of system identity, name information, product line, and visible processor count changes. System management  170  updates the system registry  180  with name information from the system ID key  150  so that outboard support processes are also immediately updated with the change, and other licensing data is saved in persistent storage. Thus the update is successfully installed on system  100  with no loss or data and no service interruption. 
         [0027]    The information system company may provide the system key  150  in a number of different ways, such as by plugging into a local port or providing the key over a network such as the Internet. In the Internet example, a customer is given the option to simply call a customer service representative of the information system company, agree to a new contract for the new system, and receive a different system while still on the call. This nearly instantaneous upgrade ability makes the system  100  very easy to scale for customer needs, and attractive to customers who&#39;s computing needs may change over time. 
         [0028]    According to the exemplary embodiments, a system name, a product line, and other system characteristics, may be branded to the computer system  100  using a system ID key generated by the external key generator module  160  without updating system management firmware. In the preferred embodiment, the branding method is performed on a running system. However, the branding method may be performed when the computer system  100  is halted by installation of the system ID key  150  directly into the systems management  170 , which updates the system registry  180  and systems management local persistent storage with licensing information from system key  150 . 
         [0029]    A system ID key  150  is only installed one time in the life of a system, unless significant component replacement requires synchronization of the virtual system serial number with the underlying hardware. When the computer system  100  is halted and subsequently restarted from a suspended state, systems management  170  reads name information from the system registry  180  and places it in the halt/load parameters. Systems management  170  also initializes operating system high memory structures with licensing data read from local persistent storage. During initialization of the computer system  100 , the operating system determines the system name and product line information using information in the halt/load parameters. The operating system also determines the identity of the system and the prior licensing state using the licensing data initialized in the high memory structures, During normal operation, the licensing state of the computer system  100  is redundantly captured on a halt/load disk to restore system identity and name information in the case that the system registry  180  data is lost or corrupt. 
         [0030]    The method of installing the system ID key is illustrated with reference to  FIG. 2 . The branding method begins at step  201  when the external key generator module  160  generates a system ID key  150  for the computer system  100 . The system ID key  150  may be generated based on the type of system, the number of processors to include, the amount of other hardware purchased by the customer, and any other identity specific configurations of the computer system  100 . Subsequently, in step  202 , the system ID key  150  is installed into a system. A machine ID is embedded into the system ID key  150 . When the key  150  is installed, the system  100  extracts the system name from the machine ID in step  204 . The computer system  100  is also able to extract product line information from the machine ID. Further, if the system ID key  150  is used to enable or disable processors of the computer system  100 , the number of processors that are to be displayed to a console within the operating system of the computer system  100  may also be extracted by the computer system  100  using the machine ID. As discussed above, the system ID key  150  may also update serial numbers, set licensing information, enable or disable hardware, or set other parameters, but these features will not be discussed in further detail below. 
         [0031]    Subsequently, the computer system  100  conveys the system name, product tine, and number of displayed processors to a data structure maintained by systems management firmware  170  to store system identity information in step  206 . This data structure may be maintained in an area of high memory and may persist beyond a suspension, stop, or start of the computer system  100 . The data structure may store additional information, such as licensing values, metered utilization data, and other system keys. 
         [0032]    In step  208 , the system  100  overwrites the current halt/load parameter name data with the key machine name index, system name, and product line. This machine name index points the halt/load parameters to took in the correct location for the system name, product line, and number of processors to display in the console. It is used in exported system interfaces to return machine name and product tine information to user applications. The system name information previously stored in the halt/load parameters was initialized during system boot by system management firmware using system name information located in the system registry. Exemplary halt/load parameter machine name link words are illustrated in  FIG. 3 . As show in  FIG. 3 , the machine name includes a six character machine name  302 , a tong machine name  304 , which may be up to 59 characters long, and a product line  306 , which also may be up to 59 characters in length. Although not shown in  FIG. 3 , the machine name link words may further include the number of processors to display in the console of the operating system and other information. 
         [0033]    Referring again to  FIG. 2 , in step  210 , the values stored in the data structure are subsequently written into systems management, and in step  212 , systems management saves the system name to the system registry. The product line and the number of processors to be displayed are also saved in the system registry in the same manner as the system name. As a result, when the computer system  100  is restarted, systems management initializes the halt/load parameters with the machine name index, system name, and product line values obtained from the system registry. Once the correct name is found by the halt/load parameters, and once the machine is restarted, user applications will display the correct system name, product line, and number of processors running. Similarly, support processes that have direct access to the system registry will also display the correct system name, product line, and number of processors running. 
         [0034]    As described above, the system name may be updated for the computer system  100  without updating the firmware of the computer system  100 . Because the firmware may remain unaffected by the system key update, the system does not need to be shut down during installation of the system ID key. Since an update may be applied without the worry of losing data or waiting through a lengthy reboot, system names may be updated quickly and easily. Thus, for example, a capacity on demand system, with a first system name, may be updated to a metering system, with a second name quickly and simply. Or in another example, a mid-range system with a first system name and a first product line may be upgraded to a high-end system with a second name and a second product line without affecting the firmware.
