系統上升級bios,環境:dell 服務器
DSU升級,又稱DELL EMC System Update,支持Linux和windows操作系統,主要可用於一下方面:
1.BIOS和fireware升級
2.OpenManager 軟件
This release of DELL EMC System Update (DSU) supports the following new features and operating systems:
- Creating a Bootable ISO using script
- Option to display Criticality of the Updates
- Network capability for DSU on RedHat and SUSE based Operating Systems
- New BIOS and Firmware updates
- In Platforms with OS Collector (version OSC_1.1) installed, DSU Comparison report will show as Downgrade to OS Collector 2.0
Advice: Apply the OS Collector 2.0 update through DSU, though DSU shows it as Downgrade.
這是dell官網的原話,支持系統級別的BIOS升級,優勢是系統級別升級,不用現場在服務器前倒騰,但劣勢是升級後如果有問題那必須去現場。下面貼一段dell官網的話。
