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.
