I am testing on a DELL OEM-R 720xd server, with a "NetXtreme II BCM57800 1/10 Gigabit Ethernet" C-NIC.
Note 1: All server firmware is updated to the latest available version.
note 2: DELL C-NIC designation: "QLogic 57800S Quad Port 2, 1GB x 2, 10Gb rNDC SFP+/DA"
note 3: the server is legacy, I have no control over the hardware.
The Server has 2 E5 2650v2 cores and 128GB DDR3 ECC RAM.
I installed PROXMOX 8.x and am testing to use CHR (7.12).
note 4: "hyper-threading" is disabled.
I pass the network card directly to the CHR through "PCI Passthrough".
note 5: I added the C-NIC to "/etc/modprobe.d/[*].conf" with the vendor and device ID, also I added "bnx2x" to the blacklist so that PROXMOX does not detect the C-NIC and becomes available for "PCI Passthrough".
So far everything works fine, in fact the "PCI Passthrough" is done correctly, I have no errors and the C-NIC interfaces are seen in CHR.
The problem is that when I check the balance of the vcores from the “Profile” tool I see that there is always one that shoots up between 80 to 98% and the rest remain at an equal average between them.
a- Is this behavior normal, in CHR?
I ask this question because in my CCR1072-1G-8S+ the balancing of the cores is equitable between all of them.
b- Can this be a bottleneck for my CHR?
I ask this because the “Networking” percentage associated with that “vcore” also skyrockets unlike the rest of the “vcore’s” and perhaps this proves to be the packet loss problem in the Bandwidth Test.
Thank you for your time and dedication in answering this question.
