This disclosure relates generally to information handling systems and more particularly to remote access controllers (RACs) in servers in data centers, and more particularly to systems and methods for monitoring and managing RACs.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems 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 information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems 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.

Firmware in RAC 14 may include a set of built in features 30 executable by a processor in RAC 14. For example, each server 12 has a power supply unit (PSU) for receiving power from a power source and transforming the power into usable power by the server 12. Firmware in RAC 14 includes power control 30-1 as a feature 30 for monitoring of power received by the PSU to determine when server 12 has switched power modes and allow for remote switching of server 12 between power modes. Similarly, server 12 has a fan for cooling server 12 and firmware in RAC 14 includes thermal control 30-2 as a feature 30 for monitoring of temperatures in server 12 to determine if the fan is operating, determining when to operate the fan and enabling remote operation of the fan.
Firmware in RAC 14 may also store hardware abstraction layer (HAL) 22 for communication with and monitoring of peripheral devices. Within HAL 22, features such as Inter-Integrated Circuit (I2C) protocol 22-1, Improved Inter-Integrated Circuit (I3C) protocol 22-2. Serial Peripheral Interface (SPI) 22-3, Reduced Media-Independent Interface (RMII) 22-4, Peripheral Connect Interface Express Vendor Defined Message (PCIe VDM) 22-5 and management component transport protocol (MCTP) 22-6 allow communications with chips, processors and microcontrollers in server 12.
Server 12 includes hardware 24 such as processors for processing information, memory for storing information, a fan for cooling server 12 including devices and components in server 12, a network integrated circuit (NIC) for communications, other controllers such as RAID controllers, and Complex Logic Programmable Devices (CPLDs). Accordingly, Firmware in RAC 14 may include other features such as Basic Input Output Service (BIOS) 26-1, NIC 26-2, fan control 26-3, PSU control 26-4 for operating a PSU, RAID feature 26-5 for managing a RAID and CPLD feature 26-6 for monitoring and managing a CPLD.
Firmware in RAC 14 may typically include other features 30 for monitoring and managing servers 12 in data centers 10. The examples depicted in
Web Graphical User Interface (GUI) 30-1 is a web-based application that processes network events for displaying the data in a graphical format for users to view on an attached display. Redfish® 30-2 is an application programming interface (API) that uses RESTful semantics to access data defined in model format for systems management. Remote Access Controller admin (RACADM) feature 30-3 is a scriptable interface to allow remote configuration of RAC 14. Simple Network Management Protocol (SNMP) feature 30-4 may be used to collect data related to network changes and determine the status of network-connected devices. Hardware inventory feature 30-5 may maintain an inventory and properties of all hardware installed on server 12. Software inventory feature 30-6 may maintain an inventory and versions of all software running on server 12. Firmware update feature 30-7 may maintain a list of firmware including versions and facilitate updates of any firmware on server 12. Monitoring feature 30-8 may monitor operation of components or devices in server 12 and record values or may define what operations are to be monitored and how the monitoring should occur. RAC 14 may include database 32 for storing information about components or devices in server 12. Network Controller-Sideband Interface (e.g., NC-SI 1.2) feature 30-10 defines a control communication protocol between a baseboard management controller (BMC) and one or more Network Interface Controllers (NICs). Platform Level Data Model (PLDM) feature 30-11 defines the contents of a firmware update package. Security Protocol and Data Models (SPDM) feature 30-12 enables authentication, attestation and key exchange for enabling security of server 12. Management Control Transport Protocol (MCTP) feature 30-13 stores message formats, transport descriptions, message exchange patterns and endpoint characteristics related to communications between components.
Servers 12 described above have several shortcomings. All features 30 are stored in memory in each RAC 14 of each server 12, regardless of whether a feature 30 will be used for a particular server 12. Furthermore, features 30 are getting more robust and require more memory to manage devices in servers 12. For example, RAC 14 in some generations of servers 12 may have 512 Megabytes (MB) of memory to store all features 30, RAC 14 in later generations of servers 12 may have 1 Gigabyte (GB) of memory to store all features 30, and RAC 14 in later generations of servers 12 may have 2 GB of memory to store all features 30. Although each server 12 is provided with the full suite of features 30, many customers or servers 12 require a limited set of features 30. For security reasons, some users prefer to have only firmware code which they know they will use. Subscription-based licensing, in which a user pays for only the features needed, may be preferred. However, only about 35% of datacenter servers 12 contain the latest firmware for RAC 14, and features 30 are often unnecessarily tied to specific hardware capabilities. Customization of features 30 via Software Developer Kits (SDK) may be limited or unavailable due to hardware capabilities or software requirements. Some devices (e.g., Baseboard Management Controllers (BMCs)) are expected to be commoditized, resulting in greater complexity and/or more features 30 that would need to be installed on each RAC 14.

Turning to one or more of
Firmware within RAC 314 on servers 312 may include a REpresentational State Transfer Application Programming Interface (REST API) 16 that allows servers 312 to communicate with each other. Remote monitoring may require communications with processes running in RAC 314. A D-Bus 18 or other inter-process communications mechanism enables local communication between processes on RAC 314. RAC 314 may further comprise Remote Procedure Call (RPC) queue 302, D-Bus to RPC mapper 304 and D-Bus to REST mapper 306 for available services 350 on private cloud server 360 to communicate with HAL 22. In some embodiments, RPC mapper 304 may be a Google RPC (gRPC) mapper 304.
RAC 314 may also store hardware abstraction layer (HAL) 22 for communication and monitoring of peripheral devices. Within HAL 22, I2C 22-1, I3C 22-2, SPI 22-3, RMII 22-4, PCIe VDM 22-5 and MCTP 22-6 allow communications with chips, processors and microcontrollers in server 312.
Embodiments of private cloud server 360 may store a set of available services 350 retrieved from MSC server 210-3. In some embodiments, private cloud server 360 may determine, based on one or more of an application to be executed on a server 312 or a data set to be processed by a server 312, that a particular available service is needed and communicate with MSC server 210-3 to retrieve the available service 350. In some embodiments, private cloud server 360 may communicate with MSC server 210-3 to retrieve an available service 350 based on a subscription. Available services 350 may be executed by private cloud server 360 unless there is a need to have RAC 314 execute the available service 350.
Embodiments may install available services 350 in RAC 314 from private cloud server 360, wherein the set of available services 350 stored in RAC 314 may be less than the total number of available services 350 stored in private cloud server 360 and less than the plurality of available services 350 stored in MSC server 210-3. Available services 350 may be installed in RAC 314 based on one or more of performance or capability. Once the process is complete or the available service 350 is no longer time-sensitive, embodiments may uninstall the available service 350 from RAC 314.
As a device-based example, referring to available service 350-13 (i.e., MCTP 350-13) and available service 350-10 (i.e., NC-SI 1.2 protocols 350-10), if a process sends a request to CPLD 26-6, a response may be expected in a minimum response time of about 50 milliseconds (ms) and a maximum response time of about 4 seconds. If the MCTP 350-13 and NC-SI 1.2 protocols 350-10 are stored in private cloud server 360, a response may take 5 seconds. Embodiments may install NC-SI 1.2 protocols 350-10 as a time sensitive plug-in 340 to ensure a response is received in less than 4 seconds. Once NC-SI 1.2 protocols 350-10 is not needed, NC-SI 1.2 protocols 350-10 may be uninstalled from RAC 314.
As another example, referring to available service 350-11 (i.e., PLDM 350-11) and available service 350-7 (i.e., Firmware update service 350-7), if there is a firmware update and PLDM 350-11 executing on private cloud server 360 cannot deliver the update payload within a maximum time (e.g., 4 seconds), the firmware update may time out. In this case, PLDM 350-11 and Firmware update service 350-7 may be installed as time sensitive plug-ins 340 to ensure the firmware update payload can be delivered in time. Once the firmware update payload is delivered, PLDM 350-11 and Firmware update service 350-7 may be uninstalled from RAC 314.
Box 352 contains a non-limiting list of available services 350 that may be installed on private cloud server 360 to communicate with RACs 314 on any servers 312 in data centers 310, wherein available services 350 in box 352 may function similar to features 30 described above with respect to
New Services and Services with Increased Scope
Embodiments may allow private cloud server 360 to provide additional available services 350 and available services 350 with increased scope that increase the capabilities of RAC 314. Box 354 contains a non-limiting list of available services 350 that may be retrieved from MSC server 210-3 and installed on private cloud server 360. Some available services 350 in box 354 may be executed by private cloud server 360. Some available services 350 in box 354 may be installed on RAC 314 on any server 312 in data center 310.
A user must have administrative credentials to run RACADM commands remotely. When a user wants to run RACADM commands, the user must first be validated by RAC 314. Traditionally, RAC 14 corresponding to server 12 in
Some Baseboard Management Controllers (BMCs) have no intelligence to adjust telemetry collection based on server events/errors or have different streaming rate for each metric. Traditionally, RAC 14 in server 12 may send the same information multiple times or at different rates, tying up networking resources and memory. Telemetry service 350-16 may be retrieved from MSC server 210-3 and installed on private cloud server 360. In some embodiments, an Open Telemetry (OTEL) service 350-16 may be stored in private cloud server 360 as an available service 350. When servers 312 communicate data for telemetry purposes, telemetry service 350-16 executing on private cloud server 360 may aggregate data, remove redundant data, or otherwise coordinate the communication of data, resulting in reduced network congestion. In some embodiments, telemetry service 350-16 may be installed in RAC 314 to meet telemetry requirements and then uninstalled after server 312 does not need to meet any telemetry requirements. In some embodiments, telemetry service 350-16 may be installed in RAC 314 as a time-sensitive plug-in 340 to provide quicker responses to telemetry requirements and then uninstalled after server 312 does not need quick responses to meet telemetry requirements.
Artificial Intelligence (AI)/Machine learning (ML) service 350-17 may include services necessary for AI/ML. If a server 312 (or a set of servers 312) is needed for AI/ML, AI/ML service 350-17 may be downloaded to private cloud server 360 for coordinating processing by servers 312 for AI/ML processing.
Third party services 350-18 may include services needed for particular third-party applications. Advantageously, instead of all available services 350 being tied to particular hardware, embodiments may enable third-party services 350-18 to execute on private cloud server 360, wherein other available services 350, RPC queue 302, D-Bus to RPC mapper 304 and D-Bus to REST mapper 306 enable third-party services 350-18 on private cloud server 360 to communicate with HAL 22 in one or more RACs 314.
Advanced power/thermal service 350-19 may be stored on private cloud server 360 and may refer to an available service 350 that can be executed on private cloud server 360 to communicate with RACs 314 on multiple servers 312 to monitor or control power or thermal operations of one or more servers 312. For example, data center 310 may have multiple floors with hundreds of racks of servers 312. Each RAC 314 may communicate with sensors inside a server 312 for remotely and individually monitoring temperature of that server 312. Advanced power/thermal service 350-19 may allow a user to remotely and collectively monitor and manage temperatures for multiple servers 312, such as all servers 312 processing a set of information, all servers 312 in a rack or all servers 312 on a floor. In some embodiments, advanced power/thermal service 350-19 may be installed in RAC 314 (e.g., as a time-sensitive plug-in 340) for quicker response to power/thermal requirements and then uninstalled after server 312 does not need to operate under advanced power/thermal requirements.
Secure Zero-Touch Provisioning (sZTP) service 350-20 enables a server 312 to securely provision a network device when booting in a default state. If server 312 is expected to require communication over a network, sZTP service 350-20 executing on private cloud server 360 may ensure the network device is securely provisioned. In some embodiments, sZTP service 350-20 may be installed in RAC 314 for booting and uninstalled once server 312 has successfully booted. In some embodiments, sZTP service 350-20 may be installed on private cloud server 360 and installed on servers 312 (e.g., as a time-sensitive plug-in 340) as needed to ensure network devices are securely provisioned.
Integrated Dell Remote Access Controller (iDRAC) Service Manager service 350-21 may refer to available services 350-21 that may be executed to monitor and manage operation of RAC 314.
Fast IDentity Online (FIDO) Device Onboard (FDO) service 350-22 allows onboarding and trusting of new devices (e.g., RAC 314) within an environment. For example, RAC 314 may be Linux-based and one or more available services 350 may be Windows-based. FDO service 350-22 may enable servers 312 to execute Linux-based services 350 and Windows-based services 350. Data centers 310 may have hundreds or thousands of servers 312. Devices in servers 312 may be removed and exchanged for newer devices. Instead of a remote user configuring each device and deploying required applications, FDO service 350-22 allows multiple devices in various servers 312 to be configured correctly. In some embodiments, FDO service 350-22 may be installed in RAC 314 for quicker configuring and deployment and uninstalled once server 312 has successfully configured and deployed new devices. In some embodiments, FDO service 350-22 may be installed on private cloud server 360 and installed on servers 312 (e.g., as a time-sensitive plug-in 340) as needed to ensure new devices are quickly configured and deployed.
IoT Integration service 350-23 may be installed on private cloud server 360 to facilitate integration between devices on servers 312. Advantageously, instead of each server 312 in multiple data centers 310 communicating with IoT integration server 210-4, private cloud server 360 may perform some of the integration, wherein other available services 350, RPC queue 302, D-Bus to RPC mapper 304 and D-Bus to REST mapper 306 enable private cloud server 360 to communicate with HAL 22 in one or more RACs 314 in servers 312 that may have different devices.
Feature Tour service 350-24 may be installed to guide users through features 30 available to server 312. Advantageously, instead of each RAC 314 in each server 312 in multiple data centers 310 storing all the information necessary to guide users through only features 30 installed on that server, private cloud server 360 may store all the information and provide information including features 30 and available services 350 available to a particular server 312. An end user may not know whether a feature is installed on server 312 or is instead an available service 350 accessible by server 312. In some embodiments, private cloud server 360 may install feature tour service 350-24 with information relevant to a particular server 312 on RAC 314 associated with the particular server 312.
IPDK service 350-25 is an open-source, vendor-agnostic framework of drivers and APIs. IPDK service 350-25 may be too large to install on each RAC 314 in each server 312. IPDK service 350-25 may be installed on private cloud server 360 for infrastructure offload and management.
For each available service 350, if the available service 350 is needed for a particular server 312, a version of the available service 350 may be retrieved from external cloud server 210 and executed on private cloud server 360, wherein RAC 314 contains a minimum number of built-in controls 20 and features 30 to communicate with private cloud server 360, wherein private cloud server 360 comprises memory and processors for executing the available service 350. If, at some later time, the available service 350 is not needed on a particular server 312, the available service 350 may be uninstalled from RAC 314 but a version may still be stored in private cloud server 360 or the available service 350 may be uninstalled from private cloud server 360.
MSO 356 may coordinate between features and ensure any service 350 is compatible with other available services 350 and hardware in server 312 and that no conflicts exist. For example, regarding telemetry, a manufacturer may have a default telemetry service 20 installed in firmware, but a customer may want to use Open Telemetry (OTel) service 350-16 or a third-party telemetry service 350-18. If the customer requests another telemetry service, MSO 356 may determine whether the requested telemetry application will work, if an existing telemetry feature needs to be disabled or an existing telemetry service 350-16 or 350-18 needs to be uninstalled.
Large Send Offload (LSO) service 358 may increase the egress throughput of high-bandwidth network connections. LSO service 358 may be installed on PCS 312, reducing workload performed by RAC 314. In some embodiments, LSO 358 enables communication with RAC Proxy on DPU service 220 to offload large workloads.
Provisioning Available Services with Redundancy
Referring to
Redundant proxy node 610 may make sure connectivity is maintained with server 312. For example, proxy node 604 may be on a first server 312 and redundant proxy node 610 may be on a second server 312. Thus, if firmware 602 needs to be updated or a server 312 needs to be powered on and proxy node 604 is down, firmware 602 may be updated using redundant proxy node 610.
Proxy node 604 and redundant proxy node 610 may form part of proxy cluster 612. Proxy clusters 612 may be configured to manage servers 312 hosting proxy nodes 604 and redundant proxy nodes 610. For example, a proxy cluster 612 may be configured such that a server 312 hosting proxy node 604 and a server 312 hosting redundant proxy node 610 are always powered on, a server 312 hosting proxy node 604 is powered on when a server 312 hosting redundant proxy node 610 is powered down, idle or not responding, or a server 312 hosting redundant proxy node 610 is powered on when a server 312 hosting proxy node 604 is powered down, idle or not responding.
Embodiments may also provide redundancy in available services 350. Cloud services server 216 may contain service cluster 622 with service pods 616-1 to 616-S in service node 614 and service pods 618-1 to 618-S in redundant service node 620. Presently, there are approximately 200 available services 350 that may be provisioned using embodiments disclosed herein. Thus, if an available service 350 cannot be provisioned using a service pod 616 (e.g., a server 312 hosting service node 614 is powered down or idle), the available service 350 may still be provisioned using redundant service pod 618. For example, service pod 616-1 may correspond with credentials service 350-15 (depicted in
