Validation-first: a multi-site Hyper-V & SCVMM residency
For a global IT services firm's state-government end client · delivered under a Dell residency contract
The client's engineers had already done the heavy lifting: hosts deployed, failover clusters formed, the network fabric built across two sites. What they asked for was not a rebuild — it was certainty. Had it been built right? Would it hold in operation? And what should the management layer look like?
We structured the residency around that question. The first three weeks were pure validation: host configuration, cluster behavior, storage and network paths — tested methodically, with findings documented as we went. No inherited assumptions, no credit given for "should be fine."
On that validated foundation, we designed the SCVMM target state and built it out across both sites, followed by enablement sessions so the client's team could run what they now owned.
The moment we tell this story for came midway through: the customer's engineering team reviewed our target-state design and challenged one of its core decisions — where the ownership boundary between Network ATC and SCVMM should sit for network configuration. They were right to push. We revised the design, and version 1.1 carries their review: a cleaner split of who manages what, agreed line by line with the people who operate the platform.
Some consultancies would call that scope friction. We call it the engagement working as designed — we engineer with the customer, not at them. A design that survives the customer's own engineers is worth more than one that was never challenged.
What remained when we left: validation reports, the revised target-state design, build documentation, and a team enabled to operate the platform. Every hour of the residency left an artifact behind.
