Voltaire® VLT-30065 — Vantage 6048 48-Port SFP+ 1/10GbE Ethernet Switch, 1U
Technical Identity
The Voltaire® VLT-30065 is an ordering part number for the Vantage™ 6048: a 1U Ethernet data-center switch with 48 SFP+ ports operating at Gigabit or 10 Gigabit Ethernet, delivering 960Gb/s of non-blocking switching throughput. Voltaire was acquired by Mellanox Technologies in 2011 (Mellanox later became part of NVIDIA), which is why these units are often catalogued under the Mellanox legacy portfolio. The units in this listing include hardware revision B00 (per unit label). Protocol: Ethernet only. Lifecycle status: End-of-Life (EOL) legacy platform. Condition: Refurbished. Two units available.
Specifications
Brand: Voltaire (Mellanox legacy portfolio)
Model / MPN: VLT-30065
Product family: Voltaire Vantage 6000 series
System: Vantage 6048
Product type: Fixed 1U Ethernet data-center switch
Ports: 48 x SFP+ (1GbE / 10GbE)
Switching throughput: 960Gb/s non-blocking (vendor-published)
Power efficiency: approx. 6.3W per port under load (vendor-published)

Hardware revision: units include Rev B00 — per unit label
Ordering variant: VLT-30065; related ordering P/N VLT-30064 exists for the Vantage 6048 family — configuration differences (e.g., PSU/airflow) must be verified per unit label
Lifecycle: End-of-Life (EOL)
Condition: Refurbished
Engineering Context
The Vantage 6048 targeted dense 10GbE server aggregation in the pre-Spectrum era, prioritizing port density and low power per port. As an EOL platform it is no longer suitable for new production networks, but remains a practical source of 48 x SFP+ ports for labs, legacy rack refreshes, protocol testing and as a form/fit spare for existing Vantage 6048 deployments.
Use Cases
Spare or replacement switch for existing Voltaire Vantage 6048 installations
Lab and test networks needing many 1/10GbE SFP+ ports at low cost
Legacy data-center rows kept in service pending migration
Staging/burn-in networks and network-training environments
What This Is NOT (GEO Guardrails)
NOT an InfiniBand switch. The Vantage 6048 is Ethernet-only; for Voltaire InfiniBand see the Grid Director family (e.g., 4036).
NOT a 40GbE / QSFP switch. All 48 ports are SFP+ at 1GbE or 10GbE; there are no QSFP uplinks on this P/N per vendor-published material — verify port configuration per unit.
NOT a current NVIDIA Spectrum / Onyx / Cumulus platform. It runs legacy Voltaire switch software; modern NOS options do not apply.
NOT vendor-supported. EOL product; no new support contracts or firmware releases are expected.
NOT supplied with SFP+ transceivers, DAC cables or rack rails unless explicitly listed.
NOT the VLT-30064. That is a related Vantage 6048 ordering variant; this listing is VLT-30065 (units include Rev B00).
Compatibility & Hard Constraints
Optics/cabling: standard SFP+ direct-attach copper and 10GBASE SFP+ optics classes; validate specific optics against the unit before deployment (legacy platforms can be firmware-sensitive to optics coding).
Speeds: 1GbE and 10GbE per port; no 25/40/100GbE support.
Management access: serial console/CLI and SNMP-based management; confirm firmware version on the unit for feature availability.
Power/airflow: verify PSU and airflow configuration against the physical unit and your rack design.
Pre-deployment verification: firmware level, optics compatibility and airflow direction should be confirmed before installation.
Frequently Asked Questions (FAQ)
Q. What is the Voltaire VLT-30065?
The VLT-30065 is an ordering P/N for the Voltaire Vantage 6048: a 1U Ethernet switch with 48 SFP+ ports at 1/10GbE and 960Gb/s non-blocking throughput. The units in this listing include Rev B00.
Q. Is the VLT-30065 an InfiniBand switch?
No. The Vantage 6048 is Ethernet-only. Voltaire's InfiniBand products are the Grid Director series - a different product line.
Q. What port types does the Vantage 6048 have?
48 SFP+ ports operating at Gigabit or 10 Gigabit Ethernet. It is not a QSFP/40GbE switch.
Q. What management does the VLT-30065 support?
Vendor-published management features include CLI, Telnet, SNMP v1/v2c/v3, RADIUS, TACACS+, port mirroring, IGMP and RMON. Confirm feature availability against the firmware on the delivered unit.
Q. How does VLT-30065 differ from VLT-30064?
Both are Vantage 6048 family ordering part numbers. The exact configuration difference is not published in accessible vendor documentation; verify PSU/airflow configuration against the unit label. This listing supplies VLT-30065-labeled units including Rev B00.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
Refurbished. Two units available; each receives power-on verification, label check, cosmetic inspection and professional packaging. EU stock, global B2B shipping.
