Data Center Architecture Review
A review engagement covering rack arrangements, power planning, and environmental observations at your Japanese co-location facility. Delivered as a written report with annotated diagrams.
A documentation engagement for teams whose institutional knowledge has accumulated in scattered notes, old tickets, and the heads of the two people who were there when everything was set up.
After three weeks, you'll have a living document covering your server estate: every host, its role, what it depends on, what depends on it, and the operational notes that make it possible to work on without guessing. Written to be read by engineers joining the team, not just the ones who built it.
The document includes maintenance practices — how to keep it current as the estate changes — so that it doesn't drift back into irrelevance the moment the engagement ends.
Every server in scope, its purpose, its configuration context, and where it sits in the broader estate — written down in one place.
What each host depends on and what depends on it — the kind of information that prevents minor changes from creating unexpected failures.
Guidance on how to keep the document current so it remains useful as the estate evolves, rather than becoming another outdated artifact.
Most server estates that have been running for more than two or three years carry the same quiet problem. The people who built it know how it works. But that knowledge lives in their memory, in old chat threads, in a wiki that hasn't been edited since the migration that happened eighteen months ago, and in a folder of runbooks that covers maybe sixty percent of what's actually deployed.
When someone new joins the team, there's a months-long ramp-up period that never quite ends. When something breaks in an unfamiliar part of the stack, people spend time reconstructing context that should already be written down. This is a documentation problem, and it has a documentation solution.
Onboarding that takes months because there's no authoritative reference for how things are configured.
Changes that produce unexpected downstream effects because no one had a clear picture of the dependencies.
Institutional knowledge concentrated in one or two people who can't always be reached during an incident.
Planning conversations that start from scratch every time because there's no shared reference for the current state.
The Server Infrastructure Documentation engagement is structured around extraction — drawing out the knowledge your team already has and putting it into a format that doesn't require them to be present for someone else to use it. We interview the engineers who know the system, review configuration sources, and assemble what we learn into a structured reference document.
The document is written to be readable: clear enough for a new team member, detailed enough for the engineers who maintain it. We cover the full scope of hosts agreed at the start of the engagement — not just the interesting parts.
We work through structured conversations with the engineers who know the system — drawing out the context that doesn't appear in configuration files.
We review existing configuration sources — whatever you have, in whatever state it's in. We don't require a clean starting point.
We trace the relationships between hosts — services that depend on each other, shared infrastructure, and the less-obvious connections that tend to cause problems during changes.
The things that aren't in any config file — known quirks, maintenance considerations, contextual history that makes the difference between a smooth change and an unpleasant one.
We agree the scope of hosts to be documented, conduct the first round of team interviews, and review whatever configuration sources your team can share. We establish the document structure that will carry the rest of the work.
We assemble the core document — host entries, dependency maps, operational notes — working through follow-up questions with your team as gaps appear. The document takes shape progressively rather than all at once.
Your team reviews the draft for factual accuracy. We incorporate corrections, add the maintenance practices section, and deliver the final document. A brief walkthrough session covers how to use and maintain it going forward.
The Server Infrastructure Documentation engagement is priced at ¥42,000 — a flat fee that covers three weeks of work, all interview sessions, configuration review, document assembly, and the final delivery walkthrough.
The maintenance practices section is included in the deliverable — not an add-on. We want the document to stay useful after we leave, which means giving your team what they need to keep it current.
The time your team spends reconstructing context — for new engineers, during incidents, before planning conversations — adds up. A structured reference doesn't eliminate that overhead entirely, but it reduces it substantially and concentrates it at the beginning of the document rather than distributing it unpredictably across the working week.
A bounded timeline from scoping to final delivery. Long enough to do the work properly, short enough to plan around without disrupting your team's operations.
The deliverable includes practices for keeping the document current. Not just a snapshot — a reference that can stay accurate as your estate evolves.
We don't require clean, complete, or well-organised existing documentation. We work from whatever you have — which is usually a mix of partial sources and team knowledge.
Before the engagement starts, we agree in writing on exactly which hosts will be documented and what the final deliverable will contain. If your estate is larger than the engagement can reasonably cover in three weeks, we'll say so at the scoping stage — not halfway through week two. The scope is fixed before we start, and the price doesn't change.
Reaching out to discuss the engagement carries no obligation. If the timing isn't right, or if a different engagement fits better, that's a fine outcome from the first conversation.
Scope agreed in writing before the engagement starts — no ambiguity on what's included.
Fixed price — no hourly overruns, no scope creep that arrives as a surprise on the invoice.
Draft review included — your team corrects factual errors before the document is finalised.
Complete document ownership — everything delivered belongs to your team, with no ongoing access dependency.
You don't need to prepare anything before reaching out. A short description of how many servers are in scope, what state your existing documentation is in, and what you'd find most useful in a reference document is enough for a productive first conversation. We'll respond within a couple of working days.

A short call to agree what's in scope, what the document will contain, and when the three weeks will run.
Three weeks later, a complete, reviewed documentation set that your whole team can use and maintain.
