GREYVIC, LLC Computer Integrated Systems Design

Facility Services

GREYVIC, LLC delivers computer integrated systems design and facility engineering as six connected disciplines. Each service is documented so that the client team can build, operate and expand the hall without re-deriving the original decisions.

Integrated Facility Layout

Integrated facility layout is the discipline of arranging an entire technology hall as one object. We start by measuring the shell, the service entrance, the delivery route and the maintenance clearances the site will actually use. From those constraints we set aisle pitch, row geometry and zoning. Compute, power, cooling and storage areas are placed relative to one another so that heat, noise and cable distance all stay within the design envelope.

The layout is issued as an aisle-by-aisle drawing set with rack elevations, marked clearances and phased construction zones. Because the layout is drawn against real dimensions, the build team can install row by row without discovering that a later row has no path to the room. Layout work also fixes the future expansion boundary, so a hall built today knows where tomorrow row will land.

Cooling and Airflow Planning

Cooling and airflow planning begins with an honest heat balance for the full load range the hall is expected to carry. We define the cold aisle as the organizing line of the room and design supply and return paths that follow it. Containment strategy, set points and redundancy are selected together, because a containment decision changes the airflow a set point must achieve.

Deliverables include airflow schematics, supply and return path drawings, target temperatures at the intake face, and a containment plan that stays continuous as cabinets are added. We also document the failure case: what happens to temperatures when one cooling unit is out, and which loads are protected first. The result is a thermal design that holds under real operating conditions rather than only on paper.

Power Pathway Design

Power pathway design traces electrical service from the entrance to the exact rack position that consumes it. We map distribution, branch circuits and receptacle locations, then document breaker coordination so that maintenance on one path never interrupts an unrelated load. Redundancy topology is chosen deliberately, with the path of each feed drawn and labeled.

The pathway set includes single-line diagrams, circuit schedules, receptacle maps and load allocations by row. We verify that the planned load stays inside the capacity of each upstream device and that the chosen topology matches the availability the client actually needs. Power and layout are checked against each other so that a receptacle never lands behind a cabinet that cannot be moved.

Rack and Containment Systems

Rack and containment systems translate the layout into physical hardware. We specify cabinet dimensions, baying hardware, vertical clearances, doors, blanking panels, brush strips and roof panels as a single coordinated set. Containment is chosen so that the line remains sealed as new cabinets are added, and cable management is planned inside the same drawing rather than left to the installer.

Deliverables include rack schedules, containment elevations, grounding references and cable pathway drawings for both power and data. We also plan the service approach so that a technician can open a door, remove a panel and reach a component without disturbing adjacent rows. Every hardware decision is traceable back to the layout and the load it serves.

Monitoring and Sensor Networks

Monitoring and sensor networks make the physical hall visible to its operators. We place temperature, humidity, power and door sensors where decisions actually happen: at the intake face, in the return plenum, at the branch circuit and at the containment boundary. Each sensor receives a naming convention, a location drawing and an escalation threshold.

The sensor network is designed alongside the power and cooling systems so that a reading can always be traced to the equipment that produced it. We document the alarm tree, the escalation path and the reporting cadence. Operators receive a clear view of conditions and a defined response for each threshold, so a small deviation is noticed long before it becomes a capacity problem.

Expansion and Migration Planning

Expansion and migration planning keeps a hall able to grow without a rebuild. We stage the next row, the next power path and the next containment run so that growth is a scheduled activity. The expansion boundary established during layout is carried forward, and each phase is checked against the capacity that remains.

Migration plans sequence the movement of live equipment with defined checkpoints and rollback positions. Each step lists the equipment affected, the tempower and thermal margin required, and the verification that must pass before the move proceeds. Because the plan is drawn against the same model as the original hall, the receiving row is known good before the first cabinet is moved into it.

Our Process

Every engagement follows the same five-stage sequence. This is what makes the drawings buildable and the hall predictable from the first survey to the final verification.

Survey

We measure the room, the shell and the service entrance, and record every fixed constraint before a single design decision is made.

Model

Layout, cooling, power, racks, sensors and expansion are modeled together so that conflicts are found in the drawing rather than on site.

Document

The model becomes a coordinated drawing set, a hardware schedule and a written build sequence that the installation team can follow directly.

Stage

Construction is divided into phases with defined checkpoints, so the hall is never left in an unverified state as work continues.

Verify

Each phase ends with verification against the design before the next load is energized, keeping the hall safe and auditable.

Handover

The client receives the drawings, the schedules and the operating thresholds, with a clear path for the next expansion phase.
