Increase network connection speed to 1Gb/s?

Question

Debian

Good afternoon,
There is a server (intel s2600cp + 2 * e5-2620) with 4 network cards on board, PROXMOX virtualization system.
Switch 24 port, those. all ports are gigabit with a bandwidth of 48Gb / s
While 1 network card is configured and used. Bridge tuned.

Question 1: Do I understand correctly, in order to increase the speed of the network with devices, etc. computers \servers not virtual servers need to configure bonding on the remaining network cards?
Question 2: The most relevant at the moment is how to make / increase the speed to the nominal value of 1Gb / s for connecting through a switch.
Question 3: It is possible to throw one network from a server into a virtual machine, I think this will be a temporary solution.
Thank you.

Answer 1

1) To make bonding, you need a MANAGED switch. Yours is no good. More precisely - still better manageable with support for 802.3ad LACP
2) The speed of 100Mb is not normal, but the whole question is how and what you measure. I recommend mastering iperf and testing the speed with and without a switch (by direct connection of two adapters).
3) There is an ethtool utility, through which you can see at what speed the adapter connected to the switch. Read how you can, for example, here - lexpr.ru/ethtool
4) The case may be in bad or incorrectly crimped cables. At least see point 3.
5) About virtio Already wrote to you.
6) Yes, you can throw a completely physical adapter into a virtual machine (and even make several virtual ones from one adapter!). To do this, the server must be able to VT-d / IOMMU (enabled in the BIOS), and adapters - SR-IOV / VFIO.

Answer 2

Virtual machines already have the latest virtio 171 drivers from redhat.
This is not the question. And the fact is that the speed outside the virtual switch falls sharply and does not give out more than 100 megabits!

Answer 3

Set up intelligent bonding on the network card, and on the lacp switch, distribute the receiver and transmitter ports over IP, the traffic is relatively evenly distributed if there are not very few clients
