Abstract
Description
- This disclosure relates generally to Information Handling Systems (IHSs), and more specifically, to replaceable hardware components utilized by IHSs.
- As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an Information Handling System (IHS). An IHS generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements may vary between different applications, IHSs may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in IHSs allow for IHSs to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, global communications, etc. In addition, IHSs may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
- Groups of IHSs may be housed within data center environments. A data center may include a large number of IHSs, such as servers, that are installed within chassis and stacked within slots provided by racks. A data center may include large numbers of such racks that may be organized into rows in a manner that allows administrators to access components of the IHSs via the front and back of a rack. In some instances, administrators may be able to service and replace components of a rack-mounted IHS while the IHS remains operational and installed within the rack. Such replaceable components may be referred to as being hot-pluggable. An administrator may also be able to re-configure aspects of the operation of a rack-mounted IHS through the coupling and de-coupling of cables to the various connectors that may be provided on the back of a chassis or by a rear-facing chassis component. In some instances, administrators may remove an IHS from operation in order to service or replace some of its internal components. In all such cases, it is preferable that administrators be able to access and service an IHS as easily and safely as possible within the constraints of a server IHS being installed within a rack of a densely packed data center.

For example, an IHS may be a personal computer (e.g., desktop or laptop), tablet computer, mobile device (e.g., Personal Digital Assistant (PDA) or smart phone), server (e.g., blade server or rack server), a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. An IHS may include Random Access Memory (RAM), one or more processing resources, such as a Central Processing Unit (CPU) or hardware or software control logic, Read-Only Memory (ROM), and/or other types of nonvolatile memory.
- Additional components of an IHS may include one or more disk drives, one or more network ports for communicating with external devices as well as various I/O devices, such as a keyboard, a mouse, touchscreen, and/or a video display. An IHS may also include one or more buses operable to transmit communications between the various hardware components. An example of an IHS is described in more detail below. It should be appreciated that although certain IHSs described herein may be discussed in the context of enterprise computing servers, other embodiments may be utilized.
- As described, in a data center environment, a server IHS may be installed within a chassis, in some cases along with other similar server IHSs. A rack may house multiple such chassis and a data center may house numerous racks. Each rack may host a large number of IHSs that are installed as components of a chassis with multiple chassis stacked and installed within a rack. In certain instances, the front-side of such rack-mounted chassis may include one or more bays that each receive an individual replaceable component, such as a storage drive or a computing node. Some rack-mounted chassis may be multiple rack units in height and may house multiple IHSs. For example, an IHS may be housed within a 2 RU (2 Rack Units) chassis that houses two levels of 1 RU components. In some cases, these components may be removeable components that may be inserted and extracted from rear-facing bays of the chassis. In some cases, these components may be hot-swappable components that may be removed and replaced by administrators while at least a portion of the IHS remains operational. In a data center environment, such hot-swappable components must support safe and efficient replacement of the components by administrators. Embodiments support safe and efficient replacement of nested components of an IHS that are both inserted in a single bay of a chassis, where the components may be replaced without using tools and with minimal opportunity for errors in removing the components from the bay in the wrong order.

Although the embodiments provided herein describe an IHS that is a rack-mounted server, other embodiments may be implemented using other types of IHSs. In the illustrative embodiment ofFIG. 1 ,IHS 100 may be a server that would typically be installed within a chassis, that in turn would be typically installed within slots of a rack. Installed in this manner,IHS 100 may utilize certain shared resources provided by the chassis and/or rack, such as power and networking. In some embodiments, multiple servers such asIHS 100 may be installed within a single chassis. -
IHS 100 may include one ormore processors 105. In some embodiments,processors 205 may include a main processor and a co-processor, each of which may include a plurality of processing cores. As illustrated, processor(s) 105 may include anintegrated memory controller 105 a that may be implemented directly within the circuitry of theprocessor 105, or thememory controller 105 a may be a separate integrated circuit that is located on the same die as theprocessor 105. Thememory controller 105 a may be configured to manage the transfer of data to and from thesystem memory 110 of theIHS 105 via a high-speed memory interface 105 b. -
System memory 110 may include memory components, such as such as static RAM (SRAM), dynamic RAM (DRAM), NAND Flash memory, suitable for supporting high-speed memory operations by the processor(s) 105.System memory 110 may combine both persistent, non-volatile memory and volatile memory. In certain embodiments, thesystem memory 110 may be comprised of multiple removable memory modules. Thesystem memory 110 of the illustrated embodiment includesremovable memory modules 110 a-n. Each of theremovable memory modules 110 a-n may utilize a form factor corresponding to a motherboard expansion card socket that receives a type ofremovable memory module 110 a-n, such as a DIMM (Dual In-line Memory Module).

IHS 100 may operate using a chipset that may be implemented by integrated circuits thatcouple processor 105 to various other components of the motherboard ofIHS 100. In some embodiments, all or portions of the chipset may be implemented directly within the integrated circuitry of anindividual processor 105. The chipset may provide the processor(s) 105 with access to a variety of resources accessible via one ormore buses 115. Various embodiments may utilize any number of buses to provide the illustrated pathways provided by the single illustratedbus 115. In certain embodiments,bus 115 may include a PCIe (PCI Express) switch fabric that is accessed via a root complex and coupledprocessor 105 to a variety of internal and external PCIe devices. - In various embodiments, a variety of resources may be coupled to the processor(s) 105 of the
IHS 100 viabuses 115 managed by the processor chipset. In some cases, these resources may be components of the motherboard ofIHS 100 or these resources may be resources coupled toIHS 100, such as via I/O ports 150. In some embodiments,IHS 100 may include one or more I/O ports 150, such as PCIe ports, that may be used to couple theIHS 100 directly to other IHSs, storage resources or other peripheral components. In certain embodiments, the I/O ports 150 may provide couplings to a backplane or midplane of the chassis in which theIHS 100 is installed. In some instances, I/O ports 150 may include rear-facing externally accessible connectors by which external systems and networks may be coupled toIHS 100. - As illustrated,
IHS 100 may also include apower supply unit 160 that provides the components of the chassis with appropriate levels of DC power. Thepower supply unit 160 may receive power inputs from an AC power source or from a shared power system that is provided by a rack within whichIHS 100 may be installed. In certain embodiments,power supply unit 160 may be implemented as a swappable component that may be used to provideIHS 100 with redundant, hot-swappable power supply capabilities. - As illustrated, processor(s) 105 may also be coupled to a
network controller 125, such as provided by a Network Interface Controller (NIC) that is coupled to theIHS 100 and allows theIHS 100 to communicate via an external network, such as the Internet or a LAN.Network controller 125 may include various microcontrollers, switches, adapters, and couplings used to connectIHS 100 to a network, where such connections may be established byIHS 100 directly or via shared networking components and connections provided by a rack in whichchassis 100 is installed. In some embodiments,network controller 125 may allowIHS 100 to interface directly with network controllers from other nearby IHSs in support of clustered processing capabilities that utilize resources from multiple IHSs. In some embodiments,network controller 125 may be a swappable component that may be externally accessed and replaced whileIHS 100 remains operational, for instance via a rear-facing bay of the IHS. In some embodiments, anetwork controller 125 may be coupled toIHS 100 by nesting thenetwork controller 125 within a carrier by which another component has been coupled toIHS 100, in the samemanner storage controller 130 may be nested within a carrier by which alink controller card 145 is coupled toIHS 100. -
IHS 100 may include one ormore storage controllers 130 that may be utilized to access storage drives 140 a-n that are accessible via the chassis in whichIHS 100 is installed, in some embodiments via alink controller 145.Storage controllers 130 may provide support for RAID (Redundant Array of Independent Disks) configurations of logical and physical storage drives 140 a-n. In some embodiments, storage drives 140 a-n may be replaceable, hot-swappable storage devices that are installed within bays provided by the chassis in whichIHS 100 is installed. In some embodiments, storage drives 140 a-n may also be accessed by other IHSs that are also installed within the same chassis asIHS 100. Although asingle storage controller 130 is illustrated inFIG. 1 ,IHS 100 may include multiple storage controllers that may operate similarly tostorage controller 130. In embodiments where storage drives 140 a-n are hot-swappable devices that are received by front-facing bays of chassis, the storage drives 140 a-n may be coupled toIHS 100 by couplings to amidplane 145 ofIHS 100, where the couplings are supported via connectors of the front-facing bays of the chassis. In various embodiments, storage drives 140 a-n may include SAS (Serial Attached SCSI) magnetic disk drives, SATA (Serial Advanced Technology Attachment) magnetic disk drives, solid-state drives (SSDs) and other types of storage drives in various combinations. - As with processor(s) 105,
storage controller 130 may also include anintegrated memory controller 130 b that may be used to manage the transfer of data to and from one or more memory modules 135 a-n via a high-speed memory interface. Through use of memory operations implemented bymemory controller 130 b and memory modules 135 a-n,storage controller 130 may operate using cache memories in support of storage operations. Memory modules 135 a-n may include memory components, such as such as static RAM (SRAM), dynamic RAM (DRAM), NAND Flash memory, suitable for supporting high-speed memory operations and may combine both persistent, non-volatile memory and volatile memory. As with thesystem memory 110, the memory modules 135 a-n may utilize a form factor corresponding to a memory card socket, such as a DIMM (Dual In-line Memory Module). - In some embodiments,
link controller 145 may operate as SAS (Serial Attached SCSI) expander that provides capabilities for accessing a large number of physical storage drives 140 a-n. For instance, alink controller card 145 may be coupled to a midplane ofIHS 100 and may provide access for up to 128 storage drives 140 a-n that may be inserted within bays of the chassis in whichIHS 100 is housed and thus coupled to the midplane. Since many storage controllers support connectors for a more limited number of storage drives, by coupling astorage controller 130 to alink controller card 145, thestorage controller 130 may be provided access to all of the storage drives 140 a-n that may be accessed bylink controller 145. - In some embodiments,
link controller 145 may be a card that is attached to a carrier, where the carrier is then inserted into a rear-facing bay ofIHS 100. The carrier may be pushed forward into the bay until thelink controller 145 that is fastened to the carrier is coupled to connectors of the midplane ofIHS 100. As described in additional detail below, the carrier includes one or more arms that extend to the open end of the rear-facing bay, where each arm includes a retractable handle that may be used by an administrator to extract the carrier from the rear-facing bay. In some embodiments, once a carrier and the link controller that has been fastened to the carrier have been inserted into a bay of a chassis, astorage controller 130 may then be inserted within that same rear-facing bay ofIHS 100, where thestorage controller 130 is inserted between the two arms of the previously inserted carrier. In such embodiments,storage controller 130 may be pushed forward until it has been coupled to connectors of thelink controller 145 and thestorage controller 130 is nested within the space between the arms of the carrier, such that this space serves as an inner bay within the bay in which the carrier has been previously inserted. - As illustrated,
IHS 100 includes a remote access controller (RAC) 155 that provides capabilities for remote monitoring and management of various aspects of the operation ofIHS 100. In support of these monitoring and management functions,remote access controller 155 may utilize both in-band and sideband (i.e., out-of-band) communications with various internal components ofIHS 100.Remote access controller 155 may additionally implement a variety of management capabilities. In some instances,remote access controller 155 operate from a different power plane from theprocessors 105, storage drives 140 a-n and other components ofIHS 100, thus allowing theremote access controller 155 to operate, and management tasks to proceed, while the processing cores ofIHS 100 are powered off. Various BIOS functions, including launching the operating system of theIHS 100, may be implemented by theremote access controller 155. In some embodiments, theremote access controller 155 may perform various functions to verify the integrity of theIHS 100 and its hardware components prior to initialization of the IHS 100 (i.e., in a bare-metal state). - In various embodiments, an
IHS 100 does not include each of the components shown inFIG. 1 . In various embodiments, anIHS 100 may include various additional components in addition to those that are shown inFIG. 1 . Furthermore, some components that are represented as separate components inFIG. 1 may in certain embodiments instead be integrated with other components. For example, in certain embodiments, all or a portion of the functionality provided by the illustrated components may instead be provided by components integrated into the one or more processor(s) 105 as a systems-on-a-chip. -

FIG. 4A is an illustration of a nestedhardware component 420 inserted within a carrier, according to embodiments, that supports nested, replaceable hardware components. As inFIG. 3D , the nestedcomponent 420 is inserted in the inner bay between thearms 410 a-b of the carrier that has been previously inserted in the upper rear-facing bay ofchassis 405. In this configuration, an administrator may pressbuttons 415 on the rear face ofcomponent 420 in order to release handles for extracting the nestedcomponent 420 from the inner bay of the carrier. Importantly, the retractable handles used for extracting the carrier are not accessible and are concealed within cavities of thearms 410 a-b. With the retractable handles of the carrier concealed in this manner, an administrator is prevented from accidentally releasing the carrier from its installed position prior to releasing and extracting nestedcomponent 420. Utilizing the described embodiments, an administrator is required to release and extract nestedcomponent 420 before even attempting to extract the carrier from the bay ofchassis 405. This prevents damage that might result to the couplings between the nestedcomponent 420 in the component fastened to the carrier if the carrier and the nestedcomponent 420 were both pulled out of the bay while still connected. Additionally, inadvertent decoupling of the carrier when an administrator intends to decouple the nestedcomponent 420 may result in various unintended consequences, including unintended downtime. -

InFIG. 4B , and administrator has pressedbuttons 415 of the nestedcomponent 420 such that handles 425 have been released and used to pull the nestedcomponent 420 in the indicated direction. The administrator may pull the nestedcomponent 420 to decouple it from the carrier, and the component fastened to the carrier, such that the carrier remains in place within the upper bay of thechassis 405. In some instances, the nestedcomponent 420 will be serviced or replaced and re-inserted into the inner bay of the carrier without removal of the carrier. In such instances, the component fastened to the carrier may remain operational while the nestedcomponent 420 is replaced. -
FIG. 4C is an illustration of carrier ready for extraction from a rear-facing bay of achassis 405, according to embodiments, that supports nested, replaceable hardware components, where the retractable handles of the carrier are in an extended position. With the nested component removed from theinner bay 425 between thearms 410 a-b of the carrier, theretractable handles 430 are free to rotate to their extended position illustrated inFIG. 4C . As described, theretractable handles 430 may be recessed within cavities ofarms 410 a-b and may be spring-loaded when concealed in this manner. With the nested component removed, the springs of theretractable handles 430 are free to unload and the handles are rotated outward from the arm cavities in the indicated direction until the arms reach their extended position illustrated inFIG. 4C . -
FIG. 4D is an illustration of the extraction of acarrier 410, according to embodiments, that supports nested, replaceable hardware components, where the carrier is being extracted from a rear-facing bay of achassis 405. InFIG. 4D , and administrator pulls thecarrier 410 from the upper bay ofchassis 405 by pulling on thehandles 430 in the indicated direction. The force applied by the administrator serves to decouple the component fastened to the bracket portion ofcarrier 410 from its connections to the midplane ofchassis 405. As described below, in their extended position illustrated inFIG. 4D , thehandles 430 may be configured to reach a locking point that prevents rotation past a certain point when an administrator applies force on thehandles 430 in order to pull thecarrier 410 in the indicated direction. The administrator may safely hold thecarrier 410 by itsarms 410 a-b in order to fully extract it from the upper bay ofchassis 405. Upon removal, the administrator may service or replace the component that is fastened to the bracket portion of thecarrier 410.

FIG. 5 is an illustration of the components of a retractable handle of a carrier, according to embodiments, that supports nested, replaceable hardware components.FIG. 5 illustrates components used to implement aretractable handle 505 of theright arm 535 of a carrier, such as described above. As described, thearm 535 may include rails, such astop rail 540, that extend along the length of thearm 535 and serve to guide the nested component as it is inserted between the arms of carrier. When a component is nested between the arms of the carrier, theretractable handle 505 is rotated to a concealed position within a cavity of thearm 535. In the embodiment illustrated inFIG. 5 , theretractable handle 505 rotates by pivoting about apin 510 that couples the handle to anassembly 530 that is fastened within the cavity of thearm 535. - In the illustrated embodiment,
retractable handle 505 is coupled toassembly 530 by aligning ahole 545 on a base portion of thehandle 505 and ahole 525 of theassembly 530.Pin 510 may be inserted in these alignedholes pin 510 may include aprotrusion 520 on one end that limits the travel of thepin 510 within the aligned holes. With thehandle 505 coupled to theassembly 530 usingpin 510, theassembly 530 may be fastened within the cavity ofarm 535. As illustrated, atorsion spring 515 may be wound around a portion ofpin 510 such that hooks on each end ofspring 515 may be fixed to thehandle 505 and to theassembly 530. In other embodiments, rather than utilizing hooks, each end ofspring 515 may include rigid legs that correspond to structures in the base portion ofhandle 505 and of theassembly 530, where these structures hold the rigid legs of the spring firmly in place as it is loaded and unloaded. When a nested component is pushed into the inner bay between the arms of a carrier, the force applied by the component pushes thehandle 505 such that it pivots aboutpin 510 until it reaches the concealed position ofFIG. 2B . This pivoting ofhandle 505 aboutpin 510 serves to loadspring 515. - When the administrator removes the nested component from between the arms of the carrier, the energy stored in the windings of
spring 515 is released such that the spring unloads and thehandle 505 rotates to its extended position, where it can be used to pull the carrier from inside the bay of a chassis. In some embodiments, the base portion ofhandle 505 may include a structure that meets a corresponding structure ofassembly 530 when the handle has been rotated to its extended position, where these corresponding structures prevent outward rotation of thehandle 505 past a certain angle. These structures thus serve as stops that allow an administrator to firmly pull onhandle 505 such that the applied force is transferred from thehandle 505 to theassembly 530, and thus to thearm 535 of the carrier. Embodiments thus support safe and efficient removal of the carrier from within a bay of the chassis. - In some embodiments, the rear-face of arm 435 may include a
light pipe 550 that may extend along the length of the arm 435 and interface with a light source of the component that is fastened to the bracket portion of the carrier. This light pipe may be used to relay optical signals from the component fastened to the bracket portion of the carrier. For instance, a link controller card fastened to the bracket portion of the carrier may issued an optical signal vialight guide 550 when a storage controller that has been nested within the arms of carrier has been successfully coupled to the link controller card. The link controller card may issue additional optical signals when the storage controller has been recognized and is operational. The link controller card may issue additional optical signals to notify an administrator of various error conditions. Thelight pipe 550 remains visible when the nested component has been installed such that the administrator may be provided with diagnostic information regarding both the nested component and the component fastened to the carrier, thus further easing the burden of administering these nested components. - It should be understood that various operations described herein may be implemented in software executed by processing circuitry, hardware, or a combination thereof.
