- Does it work in a 10GbE network?
- Yes. The SFP28 cages accept SFP+ modules and DACs, so the ports run at 10GbE or 1GbE with the right optics. You only get 25GbE with SFP28 modules and a 25GbE switch.
- Which QNAP NAS support it?
- It fits QNAP NAS models with a free PCIe 4.0 x8 slot, and the slot also accepts PCIe 3.0 cards at lower speed. Check your model's expansion slot and QNAP's compatibility list before buying.
- What cabling and optics do I need?
- Use SFP28 DAC cables or SFP28 optical transceivers for 25GbE, or SFP+ equivalents for 10GbE. The card has empty cages, so transceivers or DACs are bought separately.
- Can I use it in a regular PC?
- Yes, it is a standard PCIe x8 card and works in desktop and server boards with an open x8 or x16 slot. Drivers are needed for non-QNAP systems.
- Is it worth it over a single-port 25GbE card?
- If you need two high-speed links, for example one to a switch and one to another NAS, it saves a slot. For a single link, a one-port card does the same job for less.
