Understanding CCU Diskless: Centralized Computing Without Local Storage

In the world of enterprise IT and industrial computing, reliability, security, and ease of management are paramount. One architecture that addresses all three is CCU Diskless—a configuration where a Central Computing Unit (CCU) operates without a local hard drive or SSD.

The Result: Better BusinessOne morning, a client’s PC blue-screened after a accidental malware download. In the old days, Leo would have spent hours re-imaging the drive. With CCU, he simply restarted the PC. Because the system was diskless, the client PC pulled a "fresh" copy of the OS from the server on boot, wiping the malware instantly. ccu diskless

Improved Uptime and Reliability: With less reliance on local hardware, there's a reduced risk of hardware failure impacting productivity. If a device fails, users can simply move to another workstation and continue working without interruption. Power On: The client PC’s BIOS/UEFI is configured

  1. Power On: The client PC’s BIOS/UEFI is configured for "Network Boot" (PXE) as the primary boot option.
  2. DHCP Request: The client broadcasts a request. The DHCP Server (often the same as the diskless server) provides an IP address and points to the Boot Server (Next-server/TFTP).
  3. Image Download: The client downloads a small boot loader (e.g., ipxe.pxe) via TFTP.
  4. OS Streaming: The boot loader connects to the Diskless Server (via TCP or UDP) and streams the OS image (Windows 10/11 or Linux) directly to the client’s RAM.
  5. RAM Execution: The OS runs entirely in volatile memory. Reads are from the server; writes (temp files) are directed to a small RAM disk or a server-side "write cache" file.
  6. Restore on Reboot: When the student logs off and the PC restarts, the RAM is cleared. The machine reverts to a pristine, "golden image" state—no viruses, no junk files, no configuration changes persist.
  • Server: FOG Project or Serva (Free PXE server).
  • Client: Raspberry Pi 4 or old laptop with HDD removed.
  • OS: Debian Live or Windows PE loaded to RAM.

  1. Boot your diskless client.
  2. Simulate an attack (download a script, connect to C2).
  3. Pull the power plug (simulating a suspect shutting down).
  4. Try to perform forensics.
  5. Result: You will fail. This failure is the most valuable training your CCU can have.
