I have done some testing for our newly built VSAN 6. I used VMware I/O Analyzer to do testing. Its all flash Vsan environment and currently have 7 nodes in the cluster. when I did 4k_50read_100rand testing, I found that there are 5x more adapter reads/writes than VM reads/writes.Could it be that all the VSAN overhead is consuming that much bandwidth. I have attached my results.

Are your VMs and vSAN networking sharing the same nics ?

So you traffic is mixed between VM, and vSAN replication traffic.

replication between nodes, as was previously posted.

we have enabled nic portioning.  and using explicit failover order load balancing. active uplink0 and a standby uplink1 for VM port group. and then a active uplink1 and standby uplink0 for VSAN port group.

Normal. vSAN is Cluster Storage e.g. replicated via your network via Multicast, hence why 10GBe is highly recommended, for fast replication, and resilience, on all local nodes, based on your storage policy selected.
