Rack layouts, connections, IP addresses, DNS and certificates are connected parts of the same system. I value records that support operations without leaving installation and maintenance knowledge in one person’s memory. Power, cooling and physical-security requirements belong in coordination with the responsible specialists.
Scope
- Rack, device-placement and connection diagrams
- Topology, VLAN, IP-address and port plans
- WAN, fibre, patch-panel and Wi-Fi coverage records
- Firewall-rule and service-dependency documentation
- Domains, public / internal DNS and record management
- A / CNAME / MX and SPF, DKIM, DMARC coordination
- TLS, device certificate, PKI and renewal-schedule topics
- UPS, PDU, temperature and humidity monitoring requirements
- Maintenance, physical access and emergency checklists
Intended outcome
Infrastructure documentation that makes installations, connections, access and renewals understandable and stays current as things change.
