Issues with a 40G network

Job Description:

I had a 1Gb network which I upgraded recently to 40Gbps.

I have DELL servers with ESXi7 installed.

My issues.

When I run iperf between two virtual machines, I get a bandwitch ranging from 6Gbits/sec to 10Gbits/sec.

When I copy files with scp I getting a transfer speed of about 110-120MB/s which is very far from the theorical bandwitch of 1GB/s x 4 ~ 4G/s for a 40G network.

Recently I discovered that encryption reduce transfer speed so, I setup FTP server. Transfer speed doubled with FTP. I got a transfer rate about 240-280 MB/s.

I also updated MTU to 9000 on both hosts and VMs but transfer rates are still the same.

My needs.

I am looking for an Cisco/VMWare expert who can identify and solve the issue.

I need 40G Network bandwidth as configured in Switch to be reflected in Virtual machines

I also need the transfer speed to reflect as close as possible transfer speed of 40G network (~1250 MB/s x 4).

You will need to connect remotely using TeamViewer.

This is the current architecture details:

- Cisco Nexus 9396PX Switch with 40G module

- 4 Dell PowerEdge R930 Servers (VMware ESXi7 hosts)

- NVME disks on each server

- 40 Gbps Mellanox NIC on ESXi7 hosts

- QSFP+ DAC cables to connect servers to switch

Kemahiran: Linux, Pentadbiran Rangkaian, Cisco, Pentadbir Sistem, VMware
