The Intelligent Baseboard Management Controller (iBMC) is a proprietary intelligent management system and out-of-band management software designed for remote server administration. It acts as an autonomous computing subsystem, providing management and monitoring capabilities independently of the host server’s CPU, firmware (BIOS or UEFI), and operating system. This means that, unlike in-band management, iBMC functions can operate even when the operating system is inoperable, the server is powered off, or before the operating system has booted.

The primary purpose of iBMC is to simplify the management of remote systems and edge devices. It enables administrators to perform power management tasks, monitor hardware health, configure settings, and diagnose issues without requiring physical presence in the data center.

Origins and Industry Standards

iBMC adheres to industry standards such as the Intelligent Platform Management Interface (IPMI). IPMI is a set of computer interface specifications led by Intel, first published on September 16, 1998, and supported by over 200 computer system vendors. For example, Huawei utilizes its own Intelligent Baseboard Management Controller (iBMC) for remote server management, which complies with IPMI 2.0 and Redfish specifications. Similarly, Advantech developed its iBMC to simplify the management of remote systems and edge devices.

Key Implementations and Their Roles

Several major server manufacturers have developed their own implementations of remote management controllers. While Huawei and xFusion use the “iBMC” designation, Advantech also has its version. Other manufacturers use similar names for their technologies:

• Dell EMC: Uses iDRAC (Dell Remote Access Controller)
• HPE: Uses iLO (Integrated Lights-Out)
• Huawei and xFusion: Use iBMC

Let’s look at some specific implementations:

• Huawei: Huawei’s iBMC is used in servers like the Huawei FusionServer G2500, a 4U edge rack server designed for heterogeneous computing. It integrates the iBMC management module to monitor real-time system status and separate the in-band service system from the out-of-band management system. The HUAWEI X6800 server also leverages iBMC and a Hyper Management Module (HMM) for unified management.
• xFusion: xFusion’s iBMC is an out-of-band management system compliant with IPMI, SNMP, and Redfish standards. It provides a variety of functions, including Keyboard, Video, and Mouse (KVM) redirection, text console redirection, remote virtual media, and reliable hardware monitoring and management. FusionDirector, xFusion’s infrastructure management software, connects to iBMC via the REST interface (compliant with the Redfish standard) for unified server management. xFusion V5 and later servers, along with KunLun servers, support iBMC’s disk and DIMM fault prediction features.
• Advantech: Advantech introduced its iBMC as an out-of-band management solution to simplify the management of remote systems and edge devices. This hardware-integrated technology allows administrators to perform power management tasks remotely, even during software failures or OS crashes. Advantech integrates its iBMC technology with its WISE-DeviceOn software platform for comprehensive management of industrial IoT (Internet of Things) devices.

The Essential Role of iBMC in Remote Server Administration

iBMC plays a fundamental role in remote server administration by providing a secondary, autonomous communication channel to access and control equipment, even under abnormal conditions. This is crucial for business continuity and operational efficiency. Its capabilities include:

• Comprehensive Monitoring: Monitors alarms, temperature, fans, power supplies, operating system status, chassis intrusion, and power consumption. It can send alerts to a system administrator if parameters fall outside preset limits.
• Virtual Console Access (KVM): Allows remote access to the operating system (Keyboard, Video, Mouse), with support for KVM over IP.
• Remote Power Management: Enables powering on, off, forced restarts, and power cycling of the server, even if the system is powered down or the OS has failed. This is possible because the iBMC’s network interface has integrated drivers that function as long as the server is connected to power.
• Virtual Media: Allows virtualizing DVD-ROM drives, floppy drives, ISO files, IMG images, folders, and even local USB drives on the remote server, simplifying operating system installation or file transfers.
• Firmware Updates and Configuration: Enables remote updating of firmware (iBMC, BIOS, CPLD, PSU, NIC, RAID) and configuration of disk arrays (RAID).
• Diagnosis and Fault Prediction: Provides breakdown screenshots and video playback in case of system or OS failures to help identify the root cause of issues. It also offers advanced features like disk and memory module (DIMM) fault prediction.
• Network Management: Allows configuring IP addresses, subnet masks, gateways, and DNS for the iBMC. It supports IPv4 and IPv6. It also supports NC-SI (Network Controller Sideband Interface), which enables sharing a physical network port with the host, simplifying cabling and reducing the number of ports on switches.
• Security Management: Offers diversified user security control interfaces, certificate import and replacement to ensure data transmission security, and dual image backup to enhance system security. It also implements security policies such as password complexity checks, account lockout, and two-factor authentication.
• Logging and Auditing: Records system event logs (SEL), user operation logs, system execution logs, and security logs, which can be viewed and audited through the iBMC interface.

Benefits of Using iBMC in Enterprise, Edge Computing, and Data Center Environments

The use of iBMC and similar remote administration technologies offers significant advantages across various environments:

Reduced Downtime and Operational Costs (OPEX):

• Enables corrective actions through out-of-band power management, eliminating the need for on-site maintenance and drastically reducing downtime and operational costs.
• The ability to proactively diagnose and predict hardware failures (such as disks and DIMMs) helps prevent major interruptions and allows for data and service migration before a catastrophic failure occurs.
• Intelligent power management, through technologies like DEMT (Dynamic Energy Management Technology) and Power Capping, dynamically adjusts the power consumption of each component, which can reduce energy consumption by an average of 15% to 30%, significantly lowering operational expenses.

Increased Operational and Maintenance (O&M) Efficiency:

• Remote administration allows O&M teams to be faster, eliminating the need for physical travel to the server room.
• Functions like automatic OS deployment and server profile management enable batch configuration, deployment, and updates, accelerating service rollout and improving O&M efficiency.
• Intelligent asset management with iBMC and iRM allows for automatic device location identification, part-level inventory, and real-time synchronization of asset changes, improving inventory efficiency and reducing asset management security risks.

Enhanced Hardware Control and Visibility:

• Provides greater control over the hardware aspects and configuration of servers.
• Comprehensive monitoring of all hardware components and the ability to obtain detailed system and component information allow for complete visibility into server health.

Improved Security:

• Cabling for remote management cards is often assigned to a different VLAN to elevate the security level and prevent unauthorized network access.
• iBMC offers multiple security mechanisms, such as two-factor authentication, SSL certificate management, and encryption of sensitive data, protecting against unauthorized access and attacks.
• The separation of the out-of-band management system from the in-band service system ensures that remote management is unaffected even if the in-band system fails.

Enterprise and Data Center Environments:

• Centralized management of multiple servers from a single interface or platform (like FusionDirector) simplifies large-scale operations. Hierarchical management with FusionDirector Global allows for managing up to 256 lower-level FusionDirector systems and millions of devices, ideal for geographically distributed large-scale NMS requirements.
