Lenovo ThinkServer RD640 Server Review

Power Consumption


We have upgraded our power testing equipment and now use a Yokogawa WT310 power meter for testing. The Yokogawa WT310 feeds its data through a USB cable to another machine where we can capture the test results.


To test total system power use, we used AIDA64 Stability test to load the CPU, and then recorded the results. We also now add in the power use for a server from off state, to hitting the power button to turn it on, and taking it all the way to the desktop. This gives us data on power consumption during the boot up process.




With dual socket systems, power use can be rather high when fully loaded. The Lenovo ThinkServer RD640 did peak out at about 360 watts under load, and about 280 watts on boot up. Setting the server power features and CPU speed step will lower these numbers. Overall, the RD640 does not use a lot of power compared to bigger systems. This is good, as it also lowers heat output and makes for a cool running server.


Idle power use is in the range of ~110 watts, which is very good for a server of this type. Lower idle power use means less running costs in the long run, making the RD640 inexpensive to run over time.



Final Thoughts




The Lenovo ThinkServer RD640 is a powerful server that is well suited for heavy VM workloads, and offers a complete virtualization management solution.


With a large number of storage bays and onboard or optional storage adapters, the RD640 is able to handle the increasing demands of the datacenter with a wide range of options. High-speed network access comes pre-installed, and optional expansion cards can increase the capacity if needed.


The EasyStartup DVD simplifies setup of one server to many servers; it is simple to use, and walks you through a compete server OS install. We have now used EasyStartup on several Lenovo servers, and find it a breeze to use now. After the first server is configured with EasyStartup, the settings can be saved to a USB drive to set up additional servers without having to go through the whole process again. You can still do the install the manual method if you wish; everything that you will need is included on the software DVD.


Server management provided though IPMI, or the optional Lenovo Management Controller Premium Module for iKVM abilities. This allows server management just like any other server you would run into. Extended management abilities using EasyManage allow a larger number of servers to be managed with ease.


Lenovo's line of servers offer simple tool-less operation; simply unlock the server lid, pull out the air shroud, and install RAM or upgrade expansion cards. This is very simple to do, and can be done while the server is installed in a rack without any problems. Just like the server itself, the rail kit is tool-less and snaps into place, but you still need to screw in a retaining screw to lock everything into place. Once you figure out the rail install, it is rather simple to do.


It is hard to find things to not like about the RD640; we had no issues installing the OS, adding RAM, or reconfiguring the hard drives. The RD640 is open standards based, which allows it to easily fit into your existing network and work flows, and its high performance, so it will not be a bottle neck to your system.
