No idea to be honest, even if there is its scary if it can cause these kinds of problems…

Br,

Rune






You don't know wether these systems got risers or not?

That can't be difficult to find out: Are the HBA's located directly in PCIe slots on the system board, or are they instead located in riser boards that sits in the PCIe slots?

It would be very interesting to find out....

If Richards theory is correct, you got HBA's sitting in risers on the Supermicro, but on the HP you got the HBA's directly in the PCIe slots on the system board.

Yeah, there is on R720s, I think. What about on the Supermicro and HP servers?

I’ve had this problem for a while, and I have no way to diagnose what is going on, but occasionally when system IO gets high (I’ve seen it happen especially on backups), I will lose connectivity with my Fibre Channel cards which serve up fibre channel LUNS to a VM cluster. All hell breaks loose, and then connectivity gets restored. I don’t get an error that it’s dropped, at least not on the Omnios system, but I get notice when it’s restored (which makes no sense). I’m wondering if the cards are just overheating, and if heat sinks with a fan would help on the io chip.

 

Is there a PCI bridge in the data path? These can often be found on mezzanine or riser cards.
