10gb backup only managing about 80Mb
-
That's also what we do in our prod.
-
I could be wrong but from VMware world the management interface didnt transfer much data if at all. It was only used to communicate to vsphere and/or to the to the host. So no need to waste a 10gb port on something only only see kb worth of data.
Our previous server had 2x 1gb nics for management 1x 10gb nic for network 2x 10tgb nic for storage 1x 10gb nic for vmotion.

Tbh I do the same on our vmware hosts, 2x10G or 2x25G and then the management as a vlan interface on that vSwitch, aswell as the VLAN's used for storage, VM traffic and so on.
I find it much easier to keep the racks clean if we only have 2 connections from each hosts, rather than 4, since it kind of adds up really fast and makes the rack impossible to keep nice and clean when you have 15-20 machines in it + storage + switches + firewalls and all the inter-connections with other racks, ip-transit and so on.
Edit:
Except for vSAN hosts where the vSAN traffic needs atleast 1 dedicated interface, but those are the only exception. -
@nikade My 10gb nic are directly connected to my hosts.. i dont have a 10gb switch.. the mgmt is connected via switch ports...
-
@utopianfish I see, that explains a lot.
-
@nikade Yeah, that is a far from optimal setup. It will force the data to flow through the management interface before being routed to the storage NICs.
Running iostat and xtop should show the load. A better configuration IMO would be putting the storage NICs on the switch and using a separate network or VLAN for the storage I/O traffic.
Storage I/O optimization takes some time and effort. The type, number, and RAID configuration of your storage device as well as speed of your host CPUs, eize and type of memory, and configuration of your VMs (if NUMA aware, for example) all will play a role. -
@tjkreidl I think the issue is that he's got no 10G switch, hence the direct connection
But you live and you learn, best would be to pick up a cheap 10G switch and make it right! -
@nikade ok thanks.. that’s begs the question.. where can I get a cheap 10gb switch.. not sfp. Would need to be rj45 connections

Mikrotik CRS304-4XG-IN or CRS312-4C+8XG-RM

@utopianfish Or look for deals in places like amazon.com or bestbuy.com or even Ebay.com.
