## Background
PRIORITY APPLICATION
This application claims priority to co-owned U.S. Provisional Patent Application Ser. No. 60/943,423 filed Jun. 12, 2007 and hereby incorporated by reference as though fully set forth herein.


BACKGROUND
Blade enclosures are usually found installed in data centers. Data centers are usually remote installations where a few technicians handle the day-to-day operations of installing, removing, and monitoring the operations of systems. However, substantive monitoring is usually handled in an external manner. That is, the technicians have little knowledge of what programs are executing on the systems or how the systems are being used. Control over this information is the domain of system administrators who are usually located at a separate business site where the system administrators can easily interact with the end-users of these systems.
For security reasons, many data centers do not allow actual keyboard and monitors to be locally connected to the systems at the data centers, because these could provide an opening into the systems physical operations and allow unauthorized personnel to view data on the machines. Instead, full size computer monitors and keyboards at the business site are connected to the system through a remote network connection. Thus, the system administrator at the business site can stay abreast of what is happening on the system at the remote data center.
A variety of software tools are available to present information for the system administrator in various text and graphic displays. These tools allow the system administrator to readily determine which programs are running, who is using the system, how the system is operating, speed, temperature, usage capacity, etc. Unfortunately, some of this information may need to be made available to the technicians on site at the data center because the technicians have access to the physical equipment and are in a better position to fix some types of errors in the hardware operations of the system.
This information may be conveyed by colored lights and speaker tones which identify a failed component for the technician at the remote data center. For purposes of illustration, a flashing LED may identify a failed cooling fan for the technician. Since the entire machine runs together as a single unit, the technician may turn it off, make the repairs and bring the system back up. If the module failed, the system was already down, so having the technician turn off the system was of little consequence to the users. However, a flashing LED cannot differentiate between a failed component and a component that perhaps simply needs to be checked or quickly restarted. If the module did not fail and the technician shut down the entire system, such an interruption would be unacceptable to the end-users.

DETAILED DESCRIPTION
Exemplary embodiments of an on-board input and management device (also referred to as an “integrated management controller”) are disclosed. The on-board input and management device enables technicians to manage and trouble shoot components of a system when a standard user interface device is not readily available, e.g., at a remote data center.
FIG. 1 is a high-level illustration of an exemplary networked computer system 100 which may be implemented between a host site 120 (e.g., a remote data center) and one or more client sites 150-153 (e.g., a local business site). The networked computer system 100 may include one or more communication networks 110, such as a local area network (LAN) and/or wide area network (WAN).
Host site 120 may include one or more computing systems, such as a blade computing system or “rack” system 122 with a plurality of chassis or blade enclosures. Host 120 may execute any of a wide variety of applications implemented in software. Host site 120 may also provide services to other computing or data processing systems or devices. For example, host site 120 may also provide transaction processing services, email services, etc.
Host site 120 may be provided on the network 110 via a communication connection, such as a dial-up, cable, or DSL connection via an Internet service provider (ISP). Host site 120 may be accessed directly via the network 110, or via a network site 140. In an exemplary embodiment, a web portal on a third-party venue (e.g., a commercial Internet site) may facilitate a connection for one or more clients with host 120 (e.g., via back-end link 145).
The term “client” as used herein refers to one or more computing device at the client site through which one or more users (e.g., via client computing devices 155a-c) may access the host site 120. Client computing devices 155a-c may include any of a wide variety of computing systems, such as a stand-alone personal desktop or laptop computer (PC), workstation, personal digital assistant (PDA), or appliance, to name only a few examples. Each of the client computing devices may include memory, storage, and a degree of data processing capability at least sufficient to manage a connection to the host site either directly via network 110, or indirectly (e.g., via network site 140). Client computing devices may connect to network 110 via a communication connection, such as a dial-up, cable, or DSL connection via an Internet service provider (ISP).
The term “host” as used herein refers to one or more computing device which provides services to one or more client site 150-153. The host may be implemented as a rack system 122 at the host site, as explained in more detail below with reference to FIG. 2. An on-board input and management device 130 may be installed at the host site enables technicians to manage and trouble shoot components of a computing system (e.g., rack system 122) when a standard user interface device is not readily available (e.g., at a remote data center) without compromising the security of applications and data at the host site 120.
FIG. 2 is a front plan view of an exemplary rack system 122 such as may be installed at a host site (e.g., host site 120 in FIG. 1), showing an exemplary on-board input and management device 200. Exemplary rack system 122 may include a plurality of chassis or blade enclosures 124a-g, which are typically mounted within a housing. The blade enclosures 124a-g may be any suitable size and shape and may be manufactured of any suitable material, such as, e.g., a plastic or metal enclosure suitable for mounting in the housing of the rack system 122.
Each blade enclosure 124a-g may house electronic and other electronic devices. For example, the blade enclosures 124a-g may house a PC board including one or more processing units or processors and other devices and components mounted to, connected to, or positioned near the PC board. For example, rack mount servers may include data storage devices (e.g., hard disk drives, compact disc (CD) or digital versatile disc (DVD) drives, etc.) and operate in a communications network, and therefore include suitable network connection interface(s). Still other devices and components may also be mounted on or otherwise connected to the PC board, as is readily apparent to one having ordinary skill in the computer and electronic arts.
Before continuing, it is noted that the on-board input and management device 130 is not limited to use with any particular type, number, or configuration of rack system 122, blade enclosure, computer, or other electronic device. Nor is the on-board input and management device 130 limited to use in any particular type of networked computer system. The networked computer system 100 shown in FIG. 1, and the rack system 122 shown in more detail in FIG. 2 are provided as illustrations of exemplary operational environments, but are not intended to be limiting in any manner.
The on-board input and management device 130 may be installed at the host site to enable technicians to manage and trouble shoot a plurality or all components 124a-g of the rack system 122.
FIG. 2a is a more detailed front plan view of the exemplary on-board input and management device 130 shown in FIG. 2. In an exemplary embodiment, the on-board input and management device includes at least one input device 210 (e.g., up/down arrow buttons 211, 212; left/right buttons 213, 214; and accept button 215), and at least one output device (e.g., liquid crystal display (LCD) 220), in a housing 230 (e.g., injection molded plastic or other suitable material of manufacture).
Although not required, the output device 220 may be relatively small (e.g., approximately 2 to 5 inch) and a limited number of buttons may be provided in keeping with the desire for minimal footprint in rack systems (an Onboard display). Of course other embodiments are also contemplated. For example, the on-board input and management device 130 may include a touch-screen display, so that separate input devices are not needed. Also for example, the output device may also include audible output.
It is noted that modifications may be made to size, contour, and/or configuration of the input device 210 and output device 220 so that the on-board input and management device 130 can be used with any of a wide variety of systems now known or later developed. Such modifications may depend at least to some extent on design considerations, as will be readily apparent to those having ordinary skill in the art after becoming familiar with the teachings herein.
In an exemplary embodiment, the input device 210 and output device 220 are coupled to an integrated management processor so that the on-board input and management device 130 provides a simple input device to manage blade servers. The integrated management processor may be provided on a printed circuit board PCB and housed in the on-board input and management device 130, or otherwise operatively associated with the on-board input and management device 130.
Some or all components 124a-g within the rack system 122 may be controlled and managed. Installation of the components 124a-g can also be accomplished using pictorial diagram displayed of components and processes; text alerts for failures, warnings, and health status issues; and power and performance can be managed.
Accordingly, an onsite technician can be given access to the physical operation of the machines, without having access to the operating system and the data in the machine (for security purposes). The management processor and the display together allow the technician to access all physical information regarding the entire enclosure. The technician can view the enclosure as a whole seeing things like ambient temperature, power consumption, etc., or select a single blade server to examine, allowing him to view memory, processors, internal temperature, NIC address, MAC address, etc.
In addition, the on-board input and management device 130 may be powered up to assist with installation of various components of the rack system 122. For example, the on-board input and management device 130 may be used to walk a new customer through a number of steps to bring the enclosure online/ready. Warnings and failures may be displayed by a flashing screen and additional data. After installation, pictorial diagrams may assist customers when locating servers, switches, fans, power supplies, management modules, servers, etc. The customer may make selections using a page up, page down, enter, ok, update, etc. buttons from the input device 210.
In addition, the device enables allow input and output to multiple blade servers. The new unit connected to an onboard administrator allows control over all blades, i/o switches, power modules, air movers, etc. located within the enclosure. These and other features will be explained in more detail with reference to the illustrations shown in FIGS. 3a-k. 
FIGS. 3a-k are graphics illustrations showing exemplary information displayed on an exemplary on-board input and management device 130. In exemplary embodiments, software and/or firmware executes on or in conjunction with the on-board input and management device 130 (e.g., by the integrated management processor) to implement the methods and generate the output described herein (generally referred to herein as “program code”).
The program code may be implemented as one or more modules (also referred to as code subroutines, or “objects” in object-oriented programming). The location of the software may differ for various alternative embodiments. The software programming code, for example, is accessed via a bus by a processor or processors from long-term storage media of some type, such as on-board memory. Alternatively, the program code may be embodied or stored on any of a variety of known media for use with a data processing system or in any memory device such as semiconductor, magnetic and optical devices, including a disk, hard drive, CD-ROM, ROM, etc. The code may also be distributed on such media, or is distributed to users over a network of some type. The techniques and methods for embodying program code in memory, on physical media, and/or distributing software code via networks are well known and will not be further discussed herein.
In an exemplary embodiment, the program code enables control over multiple blades (or all of the blades) in the rack system 122, and enables user interaction by displaying information for each blade enclosure 124a-g. Exemplary display 300 is shown in FIG. 3a displaying, e.g., product name, number of CPUs, memory size, number of embedded NICs, including iSCSI, iLO IP address, and a description of each installed Mezzanine option card (Mezz), etc. Additional information may be accessed by the user by selecting the back button 302 (e.g., using input device 210 in FIG. 2a).
It is noted that user an input device such as the input device 210 shown in FIG. 2a to make selections displayed on an output device (e.g., an LCD display) is well understood in the arts, and therefore further description is not included herein for sake of clarity. In addition, other user selections may also be provided (e.g., as shown in subsequent figures). User selections such as these are also well understood in the arts and not described further herein.
Exemplary display 310, 312 (FIGS. 3b and 3c, respectively) may also include port mapping for embedded network interface card (NIC) ports and mezzanine ports to each specific interconnect module in the rear on the Port Information screen. In this illustration, the difference between an internal port to a switch (Int), versus actual physical external port from a pass-through (Ext) is shown, and disabled or no connections, as shown by the context sensitive Help screen available on each Insight Display screen (display 314 in FIG. 3d).
Note that the port information (FIG. 3b) allows more than one port per bay, and includes the same icon as used on the physical enclosure bays and the server hood labels to help the customer understand the connectivity. For example, the color gray may indicate that there is nothing in a particular bay, although the server could have a mezz card connection to the bay. Also for example, Int3-Mezz2:1 indicates Blade 3, Mezz 2, Port 1 is connected to Interconnect 5 internal port 3, and that mezz 2 port 2 is connected to Interconnect 6 internal port 3.
FIG. 3e illustrates viewing information of a specific blade. In this example, the user may choose which blade to communicate with by using the display buttons 316 to highlight and then press OK when pointed to the item on a Main selection menu. See FIG. 4. Then the user operates the display arrow buttons to highlight and press OK after dialing in the blade bay number. The arrow buttons may be used to highlight and press OK on Blade Info, Port Info, or Back. The enclosure health icon 318 on the left of the bottom navigation bar is also available and when selected navigates immediately to the enclosure Health Summary screen.
An exemplary Health Summary 320 is shown in FIG. 6. In an exemplary embodiment, color may be used to display the Health Summary, wherein color may indicate the following:
