Is the QLE2692 worth it over a 32Gb adapter?

If your fabric and switches run at 16Gb, yes. A 32Gb card only pays off when the whole path, including switches and storage ports, supports 32Gb.

Does it work with VMware ESXi?

Yes, QLogic 16Gb FC adapters are supported in ESXi, but check the VMware compatibility guide for your exact ESXi version and firmware level.

The QLE2692 has two FC ports for redundant paths; the QLE2690 has one. Both are 16Gb PCIe 3.0 adapters from the same line.

Typically the adapter itself with the standard full-height bracket. Low-profile brackets and optics are usually separate, so confirm before ordering.

Yes. The card provides the ports; you still need 16Gb SFP+ optics and the appropriate fiber cables to connect to your switch or storage.

Yes, it supports direct attach to storage or another HBA, but most deployments use it with an FC switch for zoning and multipathing.
