Study Notes
Firmware and Software Subsystems
- Some subsystems, like RAID controllers and Fibre Channel HBAs, have their own firmware that controls components at a lower layer than the OS kernel.
- These firmware-driven subsystems are accessed by the OS via its kernel drivers.
- Administrative users interact with these subsystems through additional software tools.
Software Installation Mechanisms
- All software installations share common mechanisms, including installation, update, maintenance, and removal.
- There are different types of software, including OS components and add-on or third-party software.
- Server software installations use specific mechanisms, which will be explored.
File System Layout
- The file system layout is organized into different locations for different components.
- The common hierarchy found on most Unix systems is explained by the reasons behind the layout.
