I need some help for 10GB connection. I actually have a Procurve 5400zl series with some port SFP+ on V2 version module. We desperately need to connect a server with pci-x slot. what can I do to have a 10gb link? If possible I'd like to use existing HW on the switch side (mean SFP+), but I'm suspecting SFP+ DAC (with a SFP+ server adapter) won't work.
If you've just got a standard 10Gbps SFP+ (i.e. HP P/N: J9150A) then all you need to do is install a 10Gbps NIC inside your server. Unfortunately PCI-X is a very old standard now and the crossover between it's use and the advent of 10Gbps NICs was very small so there's not many adapters out there.
That said Intel did produce a part called a "PXLA8591SR" which was a PCI-X adapter with a 10Gbps LC SR optics that'd connect just fine to your server. You may struggle to find them out there but try eBay and other places as I found one in the uk.
