What is the realistic throughput speed of the PCIe3 bus. I have a client who wishes to use PCIe3 RAID controllers to hand RAID sets to a server and then serve that storage to number cruncher servers via InfiniBand 5. I need to ensure the PCIe3 can handle the speed and not be a choke point. Please email me at firstname.lastname@example.org.
At least I don't know of any raid controller / disk config that fills it. And even then the problem will be to shift the data to the InfiniBand controller. Call DELL / HP / IBM sales and ask how they would do it.
