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's stability test to load the CPU, and then we recorded the results. We also now add in the power use for a server from the off state to hitting the power button to turn it on and take 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 RD340 did peak out at about 225 watts under load and at about 260 watts on boot up. Setting the server power features and CPU SpeedStep will lower these numbers. Overall, the RD340 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.
The feature list for the RD340 is very much like other servers out in the market, so what sets the RD340 aside from the others?
The first thing that caught our eye was the ease of install and access to internal components. However, that was not everything; maintenance of components like fans was very simple to do. The air shroud comes off very easily, which allows for easy CPU and memory upgrades.
We also liked the EasyStartup DVD that simplified setup of one server to many servers. With the EasyStartup program, you do not have to worry about RAID drivers and other chipset drivers; it builds it for you. Setting up the OS is also painless. After you input the required information, EasyStartup takes over and does the install for you.
You can still do the install the manual method if you wish; everything that you will need is included on the software DVD. Remote management was also a snap, and Lenovo offers several ways to manage your servers, including IPMI, KVM, and EasyManage. We did not know about the management controller premium module at first, but we found Lenovo tech support to be fast responding, friendly, and helpful. They quickly shipped a module out to us.
Lenovo offers a great line of support for their servers also. Here you can see all the options they offer.
About the only complaint we could find is it feels a little like a closed system at first, but we did work around that when installing Ubuntu on the machine. Most of the more common operating systems are available for you to install. Ubuntu Server is not on the list, so you will need to work around that if you plan to use it.
