The Datacenter license offers several unique features such as server data telemetry streaming and advanced thermal controls to help IT admins better understand and manage the datacenter.
Previously, we have done an in-depth review of the iDRAC9, based on the firmware version 3.34.34.34; if you are unfamiliar with this out-of-band management solution, that review makes an excellent starting point before taking a look at this new version. There have been three more firmware versions released after that one, a but the version 4.00.00.00 is the one including new significant innovations and enhancements.
Recapping our previous article, the iDRAC controller is a piece of hardware integrated on the motherboard of the server, which as its own processor, memory, network connection, and access to the system bus. It provides remote access to the system console (keyboard and screen), allowing the system BIOS to be accessed over the Internet when the server is rebooted. Critical features of iDRAC include power management, virtual media access, and remote console capabilities. These features give administrators the ability to remotely configure a machine as if they were sitting in front of the local console.

New advanced features and enhancements of the iDRAC Datacenter license are targeting the datacenter management needs of IT and server admins. Starting with the key features, the new version of iDRAC introduces telemetry data for analytics to optimize and automate IT operations. Also, this version offers thermal and power customization for optimizing facilities operations, scalable and automated infrastructure security, and better remote management experience for easiest problem diagnosis and remediation.
Telemetry Streaming
Analytics is a feature that has been spiking-up in recent years. Its need, in modern data centers, is no longer an option for admins and companies looking to simplify daily management tasks, monitor and predict system performance, and boost productivity. With telemetry, data centers can collect measures and data from remote systems for analysis and monitoring. Depending on how large a company is, the amount of data spread in its datacenter could be massive; it is here where telemetry and analytics make even more sense, as it helps to optimize IT operations rapidly, with actionable insight.
iDRAC telemetry streaming collects hardware metrics and status for analytics from servers, storage, networking, OS, and workloads. There are over 20 new metric reports for streaming data via Rsyslog or Redfish SSE. These new telemetry data available include serial data log, GPU inventory and monitoring, advanced CPU metrics, optical network interfaces, and more. Telemetry also decreases downtime with predictable analytics and enhances security and compliance.
Ultimately, the new iDRAC Telemetry streaming feature provides high-performance streaming of server data. It is achieved by extracting high-value data that can be leveraged by existing customers and popular analytic tools as well as enhancing Dell EMC customer support. Over 190 different server and peripheral metrics can be streamed or pulled from iDRAC, achievable due to the iDRAC agent-free architecture.
Other Key Features and Enhancements
Enhanced Security
Critical areas regarding security have been enhanced as well. Staring with an easy Multi-Factor Authentication (MFA) that uses one-time email passcodes when a new access method is detected (source IP, for example). This enhancement is targeted at SMB customers not wanting complex MFA solutions around LDAP/AD or Radius. Password security has been improved as well. Now, longer iDRAC credentials (up to 40 characters) are needed by new automated password generators. Also, in the domains of security, it has been improved the Automatic Certificate Enrollment (ACE) for auto-renewal and deployment of iDRAC9 SSL certificates, taking advantage of the Simple Certificate Enrollment Protocol (SCEP) supported in many server OS solutions. In this way, servers can automatically keep iDRAC SSL certificates renewed with zero manual scriptings or monitoring.
Thermal Manage
Another significant feature in this version of iDRAC is the customizable thermal and airflow management in PowerEdge servers; for optimizing datacenter power policies. Thermal Manage allows customers to customize the thermal operation of their PowerEdge servers. Now, it is possible to optimize server related power and cooling efficiencies across customer datacenters. This feature is integrated with OpenManage Enterprise Power Manager for optimized management experience. An advanced PCIe thermal management dashboard is also provided.
Thermal Manage key-related power features include PCIe airflow customization (LFM), Custom Exhaust Control, Custom Delta T control, System Airflow Consumption, and Custom PCIe inlet temperature.
Other Critical Enhancements
Some other crucial improvements in the iDRAC9 Version 4.00.00.00 are the new Zero Touch Provisioning via Enhanced Server Configuration Profiles (SCPs), which is useful to automatically provision customers’ bare metal servers, including OS, Configuration, and Firmware over a secure, out of band network. Another enhancement is regarding the iDRAC email alerting; now, alerts are more compatible with Cloud-based messaging and more flexible for private email domains. Also, when using remote console operations, a virtual clipboard is now available to efficiently copy text/passwords to the local clipboard and paste into HTLM5 remote console view.
Some other advanced server monitoring enhancements, available only with the iDRAC Datacenter license, are Idle server detection, which automatically detects and alerts admins to unused servers in their infrastructure. And, Agente-free OS crash and screen capture, that detects Windows OS crash events and automatically captures the desktop screenshot without installing iSM or OMSA.
Upgrading the Firmware
A walkthrough video about how to upgrade Dell EMC PowerEdge servers to version 4.00.00.00, is available from the StorageReview YouTube channel. In addition to the video, the step-by-step guide can be found in our previous iDRAC review (mentioned in the introduction), in the overview of the LifeCycle Controller section.
Conclusion
Dell EMC has released the new version of its iDRAC9 controller, version 4.00.00.00. iDRAC simplifies hardware management through the ease of use and automation. And with this new version, Dell EMC is targeting evolving trends and features of modern data centers.
