A virtual network adapter is a program (instead of a physical network adapter) that allows a computer to connect to a network. A virtual network adapter can also be used to connect all the computers on a local area network (LAN) to a larger network such as the Internet or a collection of LANs.
Here, I would like to share how to change virtual machine virtual network adapter manually. In fact, you may know you can add a new virtual adapter and choose the adapter type from drop down menu.

As we noticed that all servers vendors like HP, DELL and IBM had launched their latest generation of servers to support the Intel Nehalem which also name as Intel Xeon 5500 series high performing virtualization chipset. I had read up couples of review from the expert which provide some useful information for reference purpose.

Been a while we all working on virtualization for consolidation purpose, I am sure that 1 of the biggest selling point we always remind the customers and management is we will able to fully utilize the investment we put in for the servers in our data center with virtualization in place. Most of the time, we may still not 100% utilize the servers capacity due to some consideration of High Availability and Performance issues.
Here I am interesting to show 1 of the screen shot I capture during my stress test on the ESX host for our production machine which hit to 100% of the CPU utilization on the ESX host level.

Intel had recently acquirred the company call Neteffect which is focusing on 10Gbps ethernet adaptors technology. As 10Ge is no longer a new thing in the market, but we still do not see it become the popular solution in the industry due to the expensive switches, NIC and solution that been widely control by the technology leader in networking solution. As we may also see some technology related to infiniband which provide 20Gbps by using HCA (host channel adapter), that will be another major competitor to be compared with the 10Ge.
Personally I had been urging the storage and network vendor over and over again regarding the 10Ge products. The reason of it is pretty simple that the Fiber Channel is just too expensive to be deployed and managed VS ethernet 10Ge. But the concern is the vendor are very slow responding to the 10Ge release roadmap although customers are demanding on that.
