Project Natick has made serious waves in the data center industry over the past two months.  Natick is the name of Microsoft’s subsea data center research project.  The project aims to cut the costs of cooling modern infrastructure.  And, it may yield a service that offers content providers extra capacity in the proximity of billions of end-users.  So what can we learn from Project Natick that can be applied to data centers currently?

Which Data Center Power Outages Are Preventable?

Compared to a decade ago, downtime caused by data center power outages is exceedingly rare.  However, they can cost companies tens of thousands of dollars or more when they do occur.  Should all power outages be accepted as an unavoidable part of data center reality? Or, are there some data center power outages that are actually preventable?

This month we are thrilled to introduce Raritan’s new logo. Raritan Inc. is now Raritan, a Brand of Legrand.  On the surface, it would appear to be nothing more than semantics and a sleek new modern design.  But, there’s more to the story than that. 

Why Do Idle Servers Exist in the Data Center?

When orchestrated correctly, the data center is a symphony of disparate devices working together in complete harmony.  But, the reality is that few data centers are as orderly as the New York Philharmonic.  In 2012, the Uptime Institute published a report that found around 30% of data center servers were under-utilized or altogether idle.  But why do idle servers exist in the data center in the first place?

Understanding Overload Protection in Raritan’s Rack Transfer Switch

This past week, we opened our mailbag and found the following customer email:

Dear Raritan team,

We mostly love the 16A rated rack transfer switch so far! The physical design made it easy to connect power feeds from the back of the cabinet. The outlet-level metering and switching let us power off development servers no one was using on weeknights and weekends.  But, here’s one thing that wasn’t so great:

We recently experienced a total device failure.  We weren’t sure what it was at first, but quickly realized it was a blown fuse from both the web interface and indicator lamp/alarm on the unit. Once we replaced the fuse the unit continued operating just fine.  But, why is it there in the first place? And why not have a circuit breaker instead of a fuse?

Tl;dr What is the purpose of the fuses located on the inlet side of Raritan’s rack transfer switch and why not have a circuit breaker instead?
