Virtual IP failover issue with vmware exsi ip based hashing

The ESXi's vSwitch doesn't care about IP addresses, just MACs. The "IP hash-based routing" is about L2 load balancing - which egress port is used - and has no relevance for IP routing. You need to ...

VMware Ethernet connection to two different switches that are linked together - What can result?

ESXi's route based on originating virtual port ID is a good way for a somewhat even load distribution with a larger number of VMs - the virtual port ID is more or less a random value, associating a VM ...

HP 5900 Switch to ESXi vSwitch , how do you configure the HP port?

vSwitches use static VM/MAC-to-port distribution, do not put redundant ports in trunk mode on the physical switch. With this logic you can have complete control over frame distribution/load balancing ...

Lots of Small Requests over Broadband Connection - Slow Response Times?

Your behaviour of slow browsing and fast file transfers is consistent with DNS problems. As you stated, you are using as DNS servers 4.4.4.4 and 8.8.8.8. It is a common mistake assuming 4.4.4.4 is a ...

How can I determinte the reason of server-to-server latency in my network?

Latency issues might not be specific enough. You can certainly get round trip (millisecond) response times using basic ICMP tools like ping and traceroute. However, poor application performance / ...

Bridged Mode Networking vs. Network Bridge

I must stress that VMware (ESX) vSwitch and dvSwitch are not true bridges. They do not track MAC:port based on traffic. They do build a "CAM" table, but it's based on VM static configuration, not ...

pfSense & VMWare ESXi VLAN integration

How can I determinte the reason of server-to-server latency in my network?

A packet capture at the 9k should do the trick. You can see when each packet comes in and heads out, which will tell you the latency. I would suggest one on the interface where "Virtual Server 1" ...
