HPE Q6M26AR SN2700M 100GBE 16QSFP28 Reman Switch

HPE Q6M26AR SN2700M 16-Port 100GbE QSFP28 Remanufactured Switch

The HPE Q6M26AR is a remanufactured HPE SN2700M 100GbE switch delivering 16 QSFP28 ports for high-density, high-throughput spine or leaf deployments where per-port 100GbE capacity is the requirement and new-unit budget is a constraint. The 'AR' suffix in HPE's part numbering convention designates this as a remanufactured unit — a common procurement path in enterprise and data center environments where cost efficiency matters and the underlying hardware platform is proven. Country of origin is the United States.

Key Features

• 16x QSFP28 Ports at 100GbE: Each port runs at 100 Gigabit Ethernet over QSFP28, which means you can break out to 4x25GbE per port using standard breakout cables — useful when connecting to servers that haven't yet moved to 100GbE uplinks but share the same switch fabric. This port density suits leaf-layer aggregation in spine-leaf architectures or direct server interconnect in smaller high-performance clusters.
• SN2700M Platform: The underlying SN2700M is an HPE-branded Mellanox Spectrum ASIC-based platform, a well-understood design in high-performance compute and storage networking. If your team already operates SN-series switches, the management familiarity is a real operational advantage.
• Remanufactured (HPE AR designation): Remanufactured units go through HPE's refurbishment and testing process before resale. This is not surplus or grey-market hardware — it is a defined HPE supply chain offering, appropriate for lab environments, secondary data center tiers, or budget-constrained expansion projects where a new-unit price point is not justified.
• Ethernet Interface: Confirms standard IEEE Ethernet framing, compatible with the broader ecosystem of 100GbE NICs, DAC cables, AOC cables, and fiber transceivers available from multiple vendors.
• UNSPSC 43222612: Classified under network switches in the United Nations Standard Products and Services Code taxonomy — relevant for procurement systems that require UNSPSC coding on purchase orders.

Integration and Compatibility

The Q6M26AR is suited for environments running HPE's networking management stack or third-party open networking tooling compatible with the SN2700M platform. QSFP28 is a widely adopted form factor, meaning DAC, AOC, and optical transceiver options from multiple vendors are readily available. Before deploying in a mixed-vendor environment, verify firmware revision compatibility with your existing fabric management tooling. As a remanufactured unit, confirm the specific firmware version shipped and whether it aligns with your current production standards before racking.

Frequently Asked Questions

Q: What does the 'AR' suffix mean on the HPE Q6M26AR part number?

A: In HPE's part numbering convention, the 'AR' suffix designates a remanufactured unit. This is a defined HPE supply chain category — hardware that has been returned, tested, and refurbished to HPE standards — distinct from new ('B' suffix) or open-box units.

Q: How many 100GbE ports does the Q6M26AR provide?

A: The Q6M26AR is based on the SN2700M platform, which provides 16 QSFP28 ports, each capable of 100GbE. QSFP28 ports also support breakout to 4x25GbE using standard breakout cables.

Q: Is the Q6M26AR appropriate for a production data center deployment?

A: It depends on your organization's policy on remanufactured hardware. Many enterprises use AR-designated HPE units in secondary tiers, lab environments, and budget-constrained expansions. For primary production spine roles, evaluate your support contract requirements and firmware currency before committing.

Q: What cable types are compatible with the QSFP28 ports?

A: QSFP28 supports direct-attach copper (DAC) cables, active optical cables (AOC), and SR4/LR4 optical transceivers. The specific reach and transceiver compatibility should be verified against HPE's compatibility matrix for the SN2700M platform.

Karl Wilson

The HPE Q6M26AR is one of those units that shows up in procurement discussions when a team needs proven 100GbE switching capacity without the new-unit price tag. The 16x QSFP28 port configuration on the SN2700M platform is a well-understood design in high-throughput environments — if you've already sized your cabling and transceivers for QSFP28, this remanufactured unit slots directly into that plan.

Technical Highlights:

• 16x QSFP28 at 100GbE: Full 100GbE per port means no per-port oversubscription at the access layer for 100GbE-connected servers — relevant in HPC, NVMe-oF storage, or dense virtualization environments where east-west bandwidth is the bottleneck.
• Breakout capability: QSFP28 to 4x25GbE breakout lets you serve 25GbE-connected servers from the same switch fabric without adding another tier — keeps your port count flexible during a phased server refresh.
• Remanufactured HPE supply chain: The AR designation is a formal HPE product category with its own part number in the HPE catalog — not ad-hoc surplus. That distinction matters when you need a support contract or need to match the unit to an HPE Care Pack.

Deployment Considerations:

• Verify the firmware version on arrival against your current production fabric before racking — remanufactured units may ship on an older firmware revision than a new-unit order would.
• HPE Care Pack coverage for AR-suffix units can differ from new-unit entitlements; confirm support terms with HPE before treating this unit as equivalent to a new deployment in a production SLA environment.

Best fit for secondary data center tiers, lab-and-staging infrastructure, or budget-constrained spine expansion in environments already standardized on HPE SN-series switching — where the platform is proven and new-unit pricing is hard to justify.
