1. Management
Dell officially provides four solutions for remote management of server hardware:
This article describes the different options for managing Dell PowerEdge servers. Installation instructions and advanced configuration information are provided in the interactive user guide. iDRAC is a controller card embedded on the motherboard that provides a basic level of management. Advanced management options are provided at the operating system level through the OpenManage suite and SupportAssist.
First, all management tools rely on the integrated Dell Remote Access Control Card (iDRAC). This is a management card that simplifies server management tasks such as configuration, deployment, servicing, user customization, and updates. iDRAC provides a web interface to manage the server remotely. The management tools use SNMP protocol to communicate with iDRAC and get hardware status. There are currently different versions of iDRAC, iDRAC 7 runs on 12G servers, iDRAC 8 runs on 13G servers, and iDRAC 9 runs on 14G servers.
| Name | type | interface | Supported OS | Remark |
|---|---|---|---|---|
| iDRAC | A physically installed management local device. Can be accessed remotely. | HTTP | operating system independent | Charges/Required/Hardware |
| OpenManage Server Administrator（OMSA） | Software installation to manage a server. Can be accessed remotely. | HTTP | Windows。 Linux。 VMware (VIB) | Software / Advice / Free |
| OpenManage Enterprise (OME) | Software installation console for managing infrastructure. Can be accessed remotely. | HTTP | （Windows、Linux） | Unified management of charges |
| SupportAssist Enterprise | Software installation console for managing devices. | HTTP | （Windows、Linux） | Unified management of charges |
二. Dell Remote Access Controller (iDRAC)
iDRAC is hardware installed on the server board. It enables system administrators to update and manage Dell systems even when the server is turned off. iDRAC also provides a web interface and a command line interface that allow administrators to perform remote management tasks. Almost all current Dell servers have an iDRAC option.
**NOTE:**NOTE: IDRAC functionality depends on license level. This article provides more information on licensing.
Note: iDRAC benefits include the ability to launch a remote console session (similar to Remote Desktop, but works even if the OS is not booted), remotely reboot or power on/off your system, and map virtual disk drives to remote files Shared or OS deployment.
The virtual console is powerful enough to support all maintenance operations. This article Dell Lifecycle Controller as iDRAC component is another useful tool. This provides advanced functionality for updating, backing up and restoring firmware updates on Dell servers through a GUI or command line interface.
Lifecycle Controller is a tool for deploying operating system, details about operating system deployment .
This article provides how to setup and configure iDRAC .
The iDRAC manual is available on the eSupport site .
Note: For iDRAC 8 and previous versions, the default login user: root password: calvin. For newer iDRAC versions, please read this
三 OpenManage Server Administrator（OMSA）
OpenManage Server Administrator (OMSA) provides a comprehensive one-to-one systems management solution in two ways:
- Via an integrated, web browser-based graphical user interface (GUI)
- Via the operating system's command line interface (CLI).
How to install OpenManage Server Administrator (OMSA) on Windows- 132087 How to install OpenManage Server Administrator (VMware) on
OMSA- 179481
How to install OpenManage Server Administrator (OMSA) on Red hat- 132087 Server Administrator,
To enable system administrators to manage systems locally and remotely on the network.
- **Managed nodes:** Install the agent and web components. (Windows, Linux)
- VIB VIB: Agent for OMSA, without web components (VMware).
You can use a web browser to access the Dell OpenManage web interface from any computer on the same network as the host computer.
Enter the IP of the host OS IP followed by the OMSA post number 1311.
Launch the OpenManage web interface (sample-https: //192.168.1.100 :1311/) (replace 192.168.1.100 with your host server's IP address).
Log in with the host's root/administrator username and password.
If you install OMSA without the web component, you must access this OMSA from another device where the web component is installed .
OpenManage Server Administrator is now installed and ready to use. User Guide ** Available Online **.
四. OpenManage Enterprise
Dell EMC OpenManage Enterprise is a hardware management and monitoring console. This provides a comprehensive view of Dell EMC servers, chassis, network switches and other third-party devices on the corporate network. It is designed for the next generation of IT professionals with a focus on simplification, automation and unified data center management.
- Discover and inventory systems.
- Monitor the health of the system.
- View and manage system alerts.
- Perform system updates and remote tasks.
- View hardware inventory and compliance reports
V. Support proactive activities through SupportAssist Enterprise
SupportAssist Enterprise is an application that provides complete visibility into your Dell server infrastructure. It proactively identifies faults in your IT environment and immediately alerts you and Dell to initiate a solution.

1. IPMI
IPMI is the abbreviation of Intelligent Platform Management Interface (Intelligent Platform Management Interface), which is an industrial standard for managing peripheral devices used in enterprise systems based on Intel structure. Developed by companies such as SuperMicro. Users can use IPMI to monitor the physical health characteristics of the server, such as temperature, voltage, fan working status, power supply status, etc. It can be understood as a standard hardware interface specification, similar to the OSI network model, which can obtain hardware information.
2. BMC
The full name of BMC is Baseboard management controller, which is an embedded management microcontroller.
The full name of BMC is Baseboard Manager Controller ( BMC for short ). It monitors the power supply and temperature of the system to ensure that the system is in normal operation. In fact, BMC is the role of a housekeeper. It can manage the power supply, temperature and other performance of the whole system, and can also act as a watchdog to restart the CPU when the system crashes.
It can be understood as a general out-of-band management system, which provides hardware operation and management functions by calling the ipmi interface and the manufacturer's private interface. BMC is the collective name for server out-of-band management
3. iDRAC(Dell Remote Access Controller)
The controller has independent processors, memory, network connections, and the ability to access the system bus. The more critical functions include: power management (power management), virtual media access (virtual media access) and remote console (remote console) capabilities, which can support web browser (web browser) or command line Interface (command-line interface) way to interact. This gives the system administrator (system administrator) the ability to set and configure the server from the remote end in this way
