What this course covers
The cloud is just someone else’s computer. Eventually, every system administrator and network engineer must deal with the physical layer. This course bridges the gap between software configuration and raw metal.
You will learn:
- Server Architecture: CPUs, ECC RAM, PCIe lanes, and out-of-band management (iLO/iDRAC).
- Storage Engineering: RAID levels (0, 1, 5, 10), SAN vs NAS, NVMe vs SAS.
- Physical Racking & Power: Rack units (U), PDUs, UPS calculations, and HVAC cooling principles.
- Fiber Optics & Cabling: Single-mode vs Multi-mode fiber, LC/SC connectors, and SFP/QSFP transceivers.
Who this is for
Anyone working in enterprise IT. If you don’t know the difference between a DAC cable and Active Optical Cable, or how to properly replace a failed drive in a RAID 10 array without losing data, this course is mandatory.
