Frequently Asked Questions

Does the QLE2694 support NPIV?

Yes — the QLE2694 supports N_Port ID Virtualization (NPIV), enabling multiple virtual FC ports per physical port for virtualized SAN environments.

What SFP+ transceivers are compatible?

The QLE2694 requires 16Gb/s SFP+ FC transceivers (short-wave or long-wave). QLogic-branded or compatible third-party 16GFC SFP+ modules are supported.

Is a low-profile bracket included?

The QLE2694-CK typically ships with both full-height and low-profile brackets. Verify bracket inclusion when ordering for low-profile chassis.
