Vertiv SR2N03010NAA1 3-Rack 10kW Row Cooling System — No Redundancy

Overview

The Vertiv SR2N03010NAA1 is a pre-engineered, three-rack row cooling solution rated at 10 kW total capacity — the right choice for small-to-mid server clusters where you need contained thermal management without the footprint or cost of a full N+1 redundant deployment. It ships as a single integrated row spanning 2,700 mm, combining three 42U x 600 x 1400 mm racks, one cooling unit, and three 30 A PDUs under the SR2 platform's Power Management Controller (10kW PMC) distribution architecture.

At 3.3 kW per rack, the SR2N03010NAA1 is sized for edge deployments, compact data rooms, or dedicated surveillance server clusters where per-rack loads stay moderate. The single-cooling-unit design keeps the row footprint tight and installation straightforward — important when ceiling height, raised-floor access, or row spacing is constrained.

Key Features

• 10 kW Total Capacity: Enough headroom for three fully populated 1U/2U server racks at moderate densities. If your per-rack load is consistently under 3.3 kW, this row handles growth without thermal throttling concerns.
• Three 42U Racks (600 x 1400 mm): The 1400 mm depth accommodates standard 2-post and 4-post rail kits for most enterprise servers, NVRs, and network gear. 42U height fits full-depth UPS units and patch panels alongside active compute.
• Single Cooling Unit: One cooling unit handles the full 10 kW load in this configuration. That simplifies service contracts and spare-parts planning, though it means any cooling maintenance requires a managed thermal window — factor this into your SLA if uptime is critical.
• Three 30 A PDUs (10kW PMC Distribution): Each rack receives a dedicated 30 A PDU managed through the Power Management Controller. PMC gives you branch-circuit monitoring and load visibility per rack — useful for capacity planning when you start adding or swapping equipment.
• 2,700 mm Row Length: The assembled row footprint is 2,700 mm end-to-end. Verify your aisle width and fire-egress clearance before committing — this is a fixed-row solution, not modular per-rack.
• No Fire Suppression: This SKU (trailing AAA1) does not include integrated fire suppression. If local code or insurance requires suppression within the row enclosure, step to the AAA2 variant (SR2N03010NAA2), which adds suppression and extends the row to 3,300 mm.

When This Is the Correct Choice

Deploy the SR2N03010NAA1 when you have a defined three-rack cluster at or under 10 kW aggregate load, your facility has reliable room-level cooling as a backup thermal layer, and fire suppression within the row is not a code requirement. It is also the right fit when budget or physical space rules out a redundant cooling configuration.

When to Choose a Different Model

If a single cooling unit failure cannot be tolerated, the SR2N03010FAA1 adds a second cooling unit in the same three-rack, 10 kW configuration — full cooling redundancy with six PDUs instead of three. For higher density workloads where per-rack load exceeds 3.3 kW, the SR2N03020NAA1 scales the same three-rack row to 20 kW total (6.6 kW per rack) with the same single-unit cooling footprint. For four or five rack deployments, see the SR2N04020NAA1 and SR2N05020NAA1 respectively in the same product family.

Frequently Asked Questions

Q: How many racks are included in the SR2N03010NAA1?

A: Three racks, each 42U x 600 x 1400 mm, assembled as a single integrated row 2,700 mm in total length.

Q: What is the per-rack cooling capacity of the SR2N03010NAA1?

A: 3.3 kW per rack (10 kW total divided across three racks), supported by one cooling unit.

Q: Does the SR2N03010NAA1 include fire suppression?

A: No. This configuration does not include fire suppression. The SR2N03010NAA2 variant adds integrated fire suppression if that is required.

Q: How many PDUs are included and what amperage are they?

A: Three PDUs, each rated at 30 A, distributed via the 10kW Power Management Controller (PMC).

Q: What is the difference between the SR2N03010NAA1 and SR2N03010PAA1?

A: The SR2N03010PAA1 doubles the PDU count to six (two per rack) versus three in the SR2N03010NAA1, with all other specs — 10 kW capacity, three racks, single cooling unit, 2,700 mm row length — identical.

Q: Is this a redundant cooling configuration?

A: No. The SR2N03010NAA1 is a no-redundancy design with a single cooling unit. For N+1 cooling redundancy in the same three-rack, 10 kW footprint, specify the SR2N03010FAA1.

Marty Allison

The SR2N03010NAA1 is the baseline three-rack entry point in Vertiv's SR2 row cooling line — 10 kW total, single cooling unit, three 30 A PDUs managed through a 10kW PMC. At 3.3 kW per rack, this is a deliberate fit for edge server rooms and surveillance infrastructure clusters where load density is predictable and moderate, not for high-density compute environments chasing 10+ kW per rack.

Technical Highlights:

• 10kW PMC Distribution: The Power Management Controller provides per-branch circuit monitoring across all three 30 A PDUs — you get real load data per rack without adding a separate power monitoring overlay, which simplifies capacity planning as the cluster grows.
• 2,700 mm Row Footprint: The fixed 2,700 mm end-to-end length is the key physical constraint. This is not a modular add-a-rack system; the row length is set at manufacturing. Verify aisle dimensions and service clearance before order — retrofitting a row into an undersized room is a costly problem.
• No Fire Suppression (AAA1 suffix): The trailing AAA1 designator confirms no integrated suppression. If the authority having jurisdiction (AHJ) for your facility requires suppression within the enclosure, you need the AAA2 variant — ordering the wrong suffix will require a full replacement, not a field upgrade.

Deployment Considerations:

• With one cooling unit handling 100% of the 10 kW load, plan a maintenance window protocol before installation. Any cooling service event is a full-row thermal event — room-level backup cooling or a scheduled low-load period is necessary if you cannot tolerate an unplanned temperature rise.
• The three-PDU configuration gives one PDU per rack, which is adequate for single-feed equipment. If your servers or NVRs have dual power supplies requiring separate feed paths, step to the SR2N03010PAA1, which provides six PDUs (two per rack) at the same 10 kW capacity and 2,700 mm length.

Best fit: a three-rack surveillance server cluster in a branch office or edge data room — predictable sub-3.3 kW per-rack loads, facility-level HVAC as a thermal backstop, and no local code requirement for row-integrated fire suppression.
