Dell PowerEdge C6100 review

The PowerEdge C6100 is Dell's best-selling cloud server system. In this exclusive review, Dave Mitchell takes a closer look at this multi-node, rack dense system to find out why.

In idle we saw one, two, three and four nodes draw a total of 136W, 205W, 275W and 348W. Under pressure these figures rose to 295W, 516W, 737W and 964W respectively. An average peak of 241W per node under heavy load is low, showing just how power frugal the C6100 is.

Remote management features differ from Dell's standard PowerEdge servers as the nodes in the C6100 don't support its iDRAC upgrades. The motherboards feature a basic Intelligent Platform Management Interface (IPMI) controller that can share access with the first Gigabit Ethernet port or use the dedicated port alongside it.

Apart from some rebranding, the web console is identical to that presented by Intel's, Supermicro's and Asus' IPMI controllers. It provides a simple web browser interface where you can view all motherboard sensors for critical components.

Full control over power allows the server to be remotely switched on and off, reset or gracefully powered down. It's better value than Dell's iDRAC as KVM-over-IP remote control and virtual media services are provided as standard and not as an optional upgrade.

Despite its obvious benefits, Dell is facing very little competition to the C6100. The only real alternatives are HP's SL6500 Scalable Systems and Supermicro's Twin rack servers.

The C6100 delivers an equally high processing density in a compact rack server. Considering the specification of the review system, it is good value overall value and it has the considerable weight of Dell's DCS group behind it.

So what's our verdict?

Verdict

Dell’s PowerEdge C6100 is aimed at the middle ground between customers looking for a few rack dense systems and those requiring a few thousand. Businesses building an HPC, gaming or cloud services solution will find it has good processing density for a 2U chassis and it’s low on power consumptions as well. Supermicro was here first with its Twin² servers which are better value, but its resellers won’t be able to compete with the warranty and support services offered by Dell’s mighty DCS group.
