Hello! I am CK notes, an IT systems engineer documenting real-world datacenter experience, infrastructure engineering, and everyday life.

This first post introduces why I started this blog, the meaning behind ‘CK notes’, and the topics I plan to cover.

💡 Why the name ‘CK notes’?

When looking at the blog address or title, you might have initially thought of the fashion brand (Calvin Klein). 😄

However, CK notes carries a sincere engineering purpose:

  • CK: The initials of my name.
  • notes : Derived fromEngineering Field Notes —the verified technical practices and troubleshooting solutions documented while working directly on enterprise systems. Since starting my IT journey on September 6, 2010, I have spent over16 years building servers, enterprise storage, and virtualization clusters across numerous datacenters. This blog is an accessible, reliable technical notebook preserving that hard-earned knowledge.

🚀 Why I Started This Blog

I was never someone who wrote frequently for leisure. However, as an infrastructure engineer, I encounter complex issues and troubleshooting scenarios almost daily. Relying solely on memory felt wasteful, and having a personal reference when similar challenges arise is essential.

Previously, I documented these insights in slide decks and internal company wikis. By publishing them online, I hope they become a lifelong engineering archive for myself anda practical guide for fellow engineers working late to solve similar production incidents.

📂 Topics I Cover

  1. Practical IT & Infrastructure Engineering (Tech)

    • Enterprise servers (HPE ProLiant, etc.), SAN switches (Cisco MDS, Brocade), and enterprise storage architectures.
    • HCI and virtualization platforms (HPE SimpliVity, HPE VME, VMware vSphere, KVM) deployment and deep dives.
    • Air-gapped engineering workflows and local LLM (Ollama) operations.
    • Hands-on incident investigations and real-world troubleshooting logs.

  2. Life & Everyday Experiences (Life)

    • DIY automotive maintenance (engine oil, filter changes, and vehicle upkeep).
    • Travel logs and casual thoughts outside the datacenter.

🎯 Looking Forward

Rather than a dry, rigid technical manual, I aim to create an approachable space that blends 16 years of practical field engineering with personal experiences.

I hope CK notes grows step by step into a dependable technical library you can trust whenever challenges arise.

Thank you for visiting, and I look forward to connecting with you!
