FC-HBA - only PCI-X supported?

Hello,

the Open-E product compatiblity list only shows QLogic QLA FC-HBAs for FC target mode. As the QLA-Adapters are all based upon PCI-X, I am wondering if there is any support for Adapters based on PCI Express as most actual Mainboards doesn´t have a PCI-X slot any more.
Does someone know FC-HBAs based on PCI Express that are running in target mode?

regards

Olly

The only HBAs that we've used are PCI-Express, so obviously the PCI-Express ones work.
