There are slight differences in the DRAC's web interface across models. This denotes fourth and fifth generation of the DRAC. Functionally, the versions are equivalent but the web interface varies in appearance between generations.
Probably the strongest feature of the DRAC is the media redirection capability. From the web interface, you can redirect the server's CD-ROM and floppy media to that of your web client or an image file. The best application for this is for a brand new server and no operating system is installed. The one caveat to watch for is the boot order in the BIOS. The DRAC provides the ability to remotely power off, power on, reset, and power cycle the system, regardless of the state of the operating system.
This is especially handy in situations such as the blue screen of death or otherwise failed system that no native interaction can resolve. Be especially careful with the use of the remote power controls since this is one feature that always does as it is told.
The security models in place can allow you to prohibit the power controls, called "server control commands. The DRAC console also provides a redirection of the video display, also regardless of the operating system state. So, you could connect and see the blue screen of death, jump into the server's BIOS to configure the boot order, install an operating system, or view the console of the operating system as it's running. There are two sessions to the console permitted in most configurations.
Note that these two sessions may be in addition to an operating system method, a physical console session, and any additional hardware - such as a keyboard, video, mouse controller or software such as PC Anywhere. Dell usually has markers indicating that these interfaces are not available. Power management User can reboot power cycle , turn off and turn on the server even when the core operating system has crashed or shutdown.
Virtual media DRAC allows a user to mount remotely-shared disk images as if they were connected to the server on site. Hardware monitoring Hardware monitoring is another important feature of Dell Remote Access Controller.
How to access DRAC? You should see following screen: Enjoy your server! Was this answer helpful? Yes No. High Priority Hardware failure. Loss of IP How does your monitoring work? At QuickPacket, reliability of our hardware for guaranteed uptime is paramount. Regardless of Tag Cloud. DRAC can send notices, even if the server is down, to most of the industry's leading consoles. Ability to monitor server health. DRAC monitors the health of the hardware to identify any failures and provide the administrator with information to isolate components with problems.
This capability enables faster troubleshooting of operational and non-operational servers and potentially yields higher availability. Alphanumeric and numeric paging. Wireless devices immediately notify administrators of server problems or failure. E-mail support. Mail systems provide immediate notification of server problems or failure.
Review of hardware logs. DRAC provides access to data showing the state of the hardware and any errors that may have been logged. These logs are the best source of hardware data and help to troubleshoot problems, potentially yielding higher availability. Access to hardware sensors. DRAC provides readouts on all sensors including power, fans, disks, temperature, and voltage.
Administrators can ascertain the server's condition regardless of the state of the operating system. Boot path analysis. DRAC III lets administrators determine whether any failures occurred during the boot sequence using boot path analysis, which displays the success or failure of POSTs as the server comes up see Figure 4. This capability helps administrators to identify the status of the components before the operating system is operational.
Any errors in the boot path may be the source of why a server might not boot. By identifying the component early and isolating problems quickly, administrators may be able to reduce downtime. Figure 4. Ability to start the server, even from powered-down state. DRAC allows remote startup of the server so administrators can power up systems that are powered off at night or over a weekend. This capability reduces expenses and potentially makes administrators more productive.
Shutdown and graceful shutdown procedures. Administrators can increase their productivity by powering down the server quickly or in a controlled fashion without visiting the system. Automatic server recovery.
This feature watches the system to identify periods of inactivity that may indicate a hung condition.
The server recovery, or watchdog, is a timer set by the user that counts down from X to 0, if enabled.
