Last week, Raritan shipped our first production run of—what we believe to be—the highest-density rack power strip in the industry to date.
Like all other Raritan rack power strips sold in North America, these units are UL Listed (bear the true UL Listed Mark). They will be placed in cabinets that will obviously get very hot, so like all Raritan power strips with the part number prefix “PX2”, these units have a maximum ambient temperature of 140°F (60°C) in North American markets.
Although the customer application is confidential, generally-speaking this power strip could easily handle up to twelve blade chassis (with common configurations) in a Tier IV environment:
**This is meant as a generalization. Please be sure to consult your Raritan power architect for more detailed provisioning guidance.
Today, the status quo for cabinet densities tends to be approximately 5 to 10 kW. Raritan has been very fortunate to have partnered with some of the industry’s most forward-thinking datacenter operators and architects—and have thus designed and deployed a significant number of different power strip configurations at higher densities. For electrical reasons, they cluster in the 14kW, 25kW, 28kW, 33kW, and now 55kW ranges.
It’s a great deal of fun, and I enjoy advising clients on the best way to deploy ever-increasing power densities at minimal cost.
Here are some more photos, if you’d like to take a closer look:
I am obligated by law to mention that this power strip happens to be from Raritan’s PX2-4000 Series—which means that in addition to supplying an absurd amount of power, it also provides billing-grade (+/- 1%) kWh energy metering for every inlet, breaker, and individual outlet [C13 and C19]. It is compatible with our wide variety of environmental sensors (temp, humidity, differential air pressure, leak, door open/close); WiFi (802.11a/b/g/n) options; daisy-chaining; USB mass configuration; etc. And it can be queried via either SNMP v1/2c/3 or JSON-RPC.
But enough with the infomercial… fundamentally, I just think it’s awesome to have a single rack PDU that delivers the equivalent amount of power as consumed by five average U.S. homes.

I’ve been back from the GreenGrid Forum 2013 for over a week now, but the insights I formed there are still making my head spin.
Early on, the GreenGrid was focused on keeping data centers cool. We all remember when walking into a data center was like stepping into a refrigerator. Now that is changing. Most IT equipment can now operate reliably at much higher temperatures. So this improved the PUE of data centers without having excessive cooling.
Now, in the age of Petabyte of data being processed, a key theme at the conference was resource efficiency among huge array of compute equipment. To achieve this, we are all now focusing on more granular management. No more refrigerator approach. Now data center managers are looking for efficiencies down at the rack and device level. Take servers for instance.
Consumers of power in a server:
A GreenGrid study that was of great interest to me focused on the power required for different CPU utilization in data center servers from idle state to active state. When this state changes, the jump in energy draw is dramatic.
The main difference in power consumption between an idle server and an active one is based on the spinning of the disc when the server must move the read-write head. The differential in power utilization from idle to active is about 30%. You can see that in the chart above.
CPU utilization studies have shown that many servers sit idle for large periods of time. But even in that idle state, they spin. And the chart above shows that they are still consuming a large amount of power. The GreenGrid paper suggested segregating servers so that some development and build servers should be isolated and shut down completely when not in use. Backup servers are usually only needed at nighttime when the devices they’re backing up are idle. During the day, they could be shut down.
Another great example in the GreenGrid presentation was a server farm running 10 servers that are utilized only 50% each on average (we suspect your utilization will be even less). Five servers utilized at 100% would be exponentially more energy efficient. The question is, how to understand what each of your servers is doing on a granular level.
Power IQ is our energy management component of Raritan’s DCIM solution, and it helps your data center become dramatically more energy efficient. Here is a partial list of what this pro-active software solution can do:
Looking through that list, you can see why Raritan is excited to be in the right place at the right time. We are leaders in intelligent power management for the data center thanks to our intelligent rack power distribution units and our powerful energy management software.
