I have two HP DL360 server in a vmware environment. I have a synology unit that will accept nic bonding/link aggregation (it has two nics on it). I also have two dedicated nics on both esx hosts just for the storage access (network). On the esx server vmnic4 and 5 are on both hosts are on vlan 30. The synology unit is also on vlan 30. If I do link aggregation on the synology side, and on the vmware side will I benefit any in throughput? Or should I use the nics for the vm network. The synology unit is presenting nfs storage, and not iscsi.

You will see an improvement in performance, but have you measured current performance and utilisation of the current links?

It's only when you start to max out links and have many virtual machines, that you may notice performance increase.

Enabling Jumbo Frames can also improve performance.

HOW TO: Enable Jumbo Frames on a VMware vSphere Hypervisor (ESXi 5.0) host server using the VMware vSphere Client

One of the biggest management holes in vCenter of ESX is the vSphere Client can indicate that VM network traffic is causing a 1 GB Ethernet adapter to have a 99% utilization rate. But strangely, it doesn't display which kind of traffic is going across the virtual networks, where it came from or where it's going.

To learn which traffic is going across a virtual network, there's another free tool for vSphere: Xangati for ESX, a virtual appliance that tracks conversations on the virtual network. It's great for troubleshooting any virtual network issue, analyzing virtual desktop infrastructure and correlating vCenter performance stats with virtual network stats.

It's available as a fanastic FREE download here.
