RE: [SAGE] 2-post vs. 4-post racks

 Hi!

Well, not being a structural engineer, I can say that our company's
safety engineer made it a rule to not put anything but telecom
equipment in telcom racks (2-post).  So no large/deep servers
like v280Rs.

If you have them, they better be solidly attached top and bottom.

Subject: [SAGE] 2-post vs. 4-post racks

I now work for a company that has nothing but 2-post racks in their 
production colo.  They have a ton of 1U Intel/Linux servers stacked on 
shelves in those racks, but also an entire rack with Sun V280Rs on 
shelves, and a Sun L1000 tape library on a shelf about chest-high.  
This is the first time I've seen 2-post racks used for anything more 
than network gear and small servers (eg. Sun Netras).  It looks 
dangerous to me.

Anyone have experience with using 2-post racks with large equipment?  
Is it safe, or will these things twist & buckle in the next earthquake?
