Vertiv SR2N03010NAA2 10kW 3-Rack Row Cooling System with Integrated Fire Suppression

The Vertiv SR2N03010NAA2 is a pre-configured, three-rack row infrastructure system rated for 10kW total IT load — purpose-built for edge deployments, branch data rooms, and secondary compute clusters that need integrated power distribution and fire suppression in a fixed, predictable footprint. This is not a standalone rack; it is a complete row solution shipping as a coordinated assembly of enclosures, cooling, and distribution hardware.

Overview

The SR2N03010NAA2 combines three 42U x 600mm x 1400mm cabinets into a 3,300mm row with a single cooling unit handling the full 10kW load. The inclusion of the fire suppression system (FSS cabinet) is the key differentiator from the NAA1 variant — mandatory in jurisdictions or facilities that require active suppression at the row level without relying on a room-wide suppression system.

Key Features

• 10kW Row Capacity, 3.3kW Per Cabinet: Total IT load is distributed across three enclosures at 3.3kW per rack. At that density, you are comfortably below the thermal ceiling for most 1U/2U server configurations — plan your per-rack load carefully if running GPU nodes or dense storage, as 3.3kW fills up faster than it sounds.
• Single 10kW PMC Cooling Unit: One cooling unit manages the entire row load. This is a no-redundancy configuration — if cooling fails, the row goes down. That trade-off is acceptable for non-critical workloads or where room-level backup cooling exists. Data center cooling options are available separately if N+1 cooling redundancy is required.
• Three 30A PDUs (One Per Rack): Each of the three cabinets receives a dedicated 30A PDU, keeping circuit management straightforward and avoiding cross-cabinet distribution. The 10kW PMC distribution architecture means power monitoring and control are handled at the row level.
• Integrated Fire Suppression System: The FSS cabinet is physically incorporated into the row assembly, extending total row length to 3,300mm vs. the 2,700mm of the comparable NAA1 variant without FSS. Budget the additional 600mm in your floor plan — this is a non-trivial footprint difference in tight data rooms.
• 42U x 600mm x 1400mm Cabinet Form Factor: The 600mm width and 1400mm depth are industry-standard for 1U to 4U rackmount equipment. The 42U height accommodates full-height deployments including patch panels, cable management, and top-of-rack switching without compromising usable rack units.
• Pre-Integrated Row Architecture: Ordering as a row system versus individual components reduces on-site assembly time and eliminates compatibility guesswork between cooling, PDU, and enclosure components. The SR2N03010NAA2 arrives as a coordinated bill of materials from a single source.

When This Is the Correct Choice

The SR2N03010NAA2 fits when your load is at or below 10kW across three racks, local code or facility policy requires row-level fire suppression, and you can accept single-point cooling (no N+1). Edge data rooms, branch office server rooms, and secondary IDF build-outs with modest compute loads are the primary use cases. Browse data center rack systems to compare row configurations by rack count and capacity.

When to Choose a Different Model

If 3.3kW per rack is insufficient for your workload — GPU compute, hyperconverged nodes, or dense storage — step up to the SR2N03020NAA2, which doubles per-rack capacity to 6.6kW at the same three-rack count. If cooling redundancy is non-negotiable, the FAA2 variants in the SR2 family add a second cooling unit. If fire suppression is not required and footprint is constrained, the SR2N03010NAA1 trims 600mm from the row length. Review rack PDU options if your power requirements differ from the 30A configuration included here.

Frequently Asked Questions

Q: What is the difference between the SR2N03010NAA2 and the SR2N03010NAA1?

A: The NAA2 variant includes an integrated fire suppression system (FSS cabinet), which extends the total row length from 2,700mm to 3,300mm. All other specifications — 10kW capacity, three racks, single cooling unit, three 30A PDUs — are identical.

Q: Does the SR2N03010NAA2 include cooling redundancy?

A: No. This configuration uses a single 10kW PMC cooling unit with no redundancy. If N+1 cooling is required, the FAA2 variants in the SR2 family include a second cooling unit.

Q: How many PDUs are included and what is their amperage rating?

A: Three PDUs are included — one per rack — each rated at 30A, operating under the 10kW PMC distribution architecture.

Q: What is the total footprint of the SR2N03010NAA2 row?

A: The assembled row spans 3,300mm in length. Each cabinet is 42U tall, 600mm wide, and 1,400mm deep. The 3,300mm row length accounts for the FSS cabinet integrated into the assembly.

Q: Can this system scale to higher power densities?

A: Not within this SKU. The SR2N03010NAA2 is fixed at 10kW total / 3.3kW per rack. For higher density, the SR2N03020NAA2 supports 20kW total / 6.6kW per rack in the same three-rack row configuration with FSS.

Eden Phillips

The SR2N03010NAA2 is a straightforward system to spec when the requirements are clear: three racks, 10kW ceiling, fire suppression required by code, and no budget or space for redundant cooling. Where I see teams get into trouble is underestimating the 3,300mm row length — the FSS cabinet adds 600mm over the NAA1, and in a branch data room where every floor tile counts, that difference can block a cold aisle configuration or conflict with an existing raised-floor grid.

Technical Highlights:

• 3.3kW Per-Rack Ceiling: Sufficient for standard 1U servers and network gear, but hits its limit with dual-socket compute nodes or NVMe storage arrays pulling 4–6kW per rack. Confirm per-rack load before committing to this model.
• Single 10kW PMC Cooling Unit: The PMC (Precision Module Cooling) handles the full row load from a single unit — no redundancy. In a branch where room cooling serves as the fallback, this is an acceptable risk. In a standalone edge room with no CRAC backup, it is not.
• Integrated FSS Cabinet: Fire suppression is physically part of the row, not a separate room system. This matters for permitting — local AHJs often accept row-level suppression as a substitute for room suppression, which can reduce construction scope on a retrofit project.

Deployment Considerations:

• Floor plan the full 3,300mm before ordering — the row ships as an integrated assembly and re-arranging post-install is not straightforward. Confirm aisle clearance and door swing on both ends.
• With no cooling redundancy, this system depends on facility HVAC as a thermal backstop. Document the fallback plan and set high-temperature alerts on your DCIM or BMS before commissioning.

The SR2N03010NAA2 is the right call for a branch office or secondary edge room where local fire code mandates row-level suppression, the IT load is predictable and stays under 3.3kW per cabinet, and room-level cooling provides an adequate thermal backstop if the single PMC unit goes offline.
