IBM 00KG329 — Connect-IB InfiniBand PCIe x16 Host Channel Adapter for NeXtScale nx360 M5
Identity
This listing is for an OEM service part carrying the printed part number 00KG329, an IBM / Lenovo field-replaceable unit. Across the secondary market 00KG329 is listed consistently as a single-port Connect-IB PCIe x16 adapter for the IBM NeXtScale nx360 M5 (machine type 5467) and n1200 enclosure (5468). Connect-IB is the Mellanox host channel adapter generation that sits between ConnectX-3 and ConnectX-4, using a PCIe 3.0 x16 host interface. No IBM or Lenovo parts document naming 00KG329 was located, so this identification rests on consistent reseller data. T.E.S confirms the exact model from the unit label before dispatch.
What is confirmed about 00KG329
The printed part number is 00KG329, an IBM / Lenovo field-replaceable unit number.
Reseller listings describe it consistently as a Connect-IB PCIe x16 InfiniBand adapter.
The host platforms cited alongside it are the IBM NeXtScale nx360 M5 (5467) and the n1200 enclosure (5468).
Connect-IB, as a product family, is a Mellanox InfiniBand host channel adapter generation that uses a PCIe 3.0 x16 host interface — the x16 width being the distinguishing feature against the x8 ConnectX-3 cards.
It is a PCIe adapter card. It is not a chassis switch module and not a mezzanine or ML2 form factor card.
What is not yet confirmed
This list is deliberate. It is what T.E.S could not establish from documentation, and it is read off the physical unit before dispatch rather than guessed at here.
The underlying Mellanox order part number. Reseller listings cite a CB193A-class number for 00KG329; T.E.S has not corroborated that against Mellanox or NVIDIA documentation, and the MCB191A / MCB193A / MCB194A variants differ in port count.
Port count. Reseller titles say single-port. That is not confirmed by vendor documentation and is read off the card before dispatch.
Link speed. The Connect-IB generation covers FDR 56 Gb/s InfiniBand; QDR, FDR10, FDR, EDR, HDR and NDR are distinct and non-interchangeable generations, and the marking on this card is what settles it.
Bracket height as fitted — low-profile or full-height. Brackets are frequently swapped over a card's service life.
Firmware level, and whether the card was ever flashed to an OEM-specific image.
Request label photos before you order
Ask us for photographs of this unit's product label and we will send them before you commit to anything. This is a single unit. We will photograph the card's own label, the Mellanox board marking, the QSFP cage face and the fitted bracket so you can confirm port count and generation before you commit. If the label does not match what is described on this page, we say so and re-quote or cancel — we do not ship a substitute and hope it fits. Quote part number 00KG329 when you contact us.
Frequently asked questions
What exactly am I buying with 00KG329?
A refurbished IBM / Lenovo field-replaceable unit whose printed number is 00KG329. It is listed consistently across the secondary market as a single-port Connect-IB PCIe x16 InfiniBand adapter for the NeXtScale nx360 M5 (5467) and n1200 (5468). T.E.S located no IBM or Lenovo parts document naming 00KG329, so port count, link speed and the underlying Mellanox part number are treated as unconfirmed and read off the card before dispatch.
Is 00KG329 a ConnectX-3 or a ConnectX-4 card?
Neither, on the available evidence. Connect-IB is its own generation, sitting between ConnectX-3 and ConnectX-4, and is distinguished by a PCIe 3.0 x16 host interface where ConnectX-3 used x8. Driver, firmware and OFED support differ between these generations, so do not treat 00KG329 as a drop-in for a ConnectX-3 or ConnectX-4 part. Ask for the board photograph if this matters to your build.
Will T.E.S confirm the exact model before shipping 00KG329?
Yes, as a standard dispatch step. We read the printed 00KG329 number, the Mellanox board marking and the physical port count off the card before it leaves. If any of it contradicts this page — in particular if the card is dual-port or a different generation — we contact you before shipping.
What if 00KG329 turns out not to be what I need?
Tell us the host server, the slot width and the fabric generation you are running before you order, and we check the card against that first. If the marking shows a different variant we re-quote or cancel. If the card ships and we misread the label, it comes back at our cost.
Is the 00KG329 adapter tested?
It is cleaned, visually inspected and bench-tested where a suitable test topology is available. For an InfiniBand HCA that typically means a host power-on and PCIe enumeration check; it does not mean the card has been link-tested against a matching FDR fabric. Ask what was actually done to this card and we will tell you.
Can I get photographs of the 00KG329 card before I order?
Yes, and for this part it is worth asking. Request photos and we send images of the printed part number, the Mellanox board marking, the QSFP cage face and the fitted bracket — which together settle port count, generation and whether the bracket suits your chassis.
Why T.E.S IT-SOLUTIONS
T.E.S IT-SOLUTIONS supplies refurbished enterprise networking and server hardware from EU stock to a B2B market. On OEM service parts whose exact model is not established by the part number alone, we publish what we can verify and name what we cannot, instead of filling the gap with plausible-sounding specifications. Every unit is photographed and its label read before dispatch. If the unit differs from this page, we tell you before we ship.
