Re: Article about IBM racks

Yes, two things.

First; STEEL.  IBM racks are made to withstand most any abuse, stand 
straight, and more importantly don't flex like other racks do.  I was in 
a data center about 6 months ago that had a row of OEM racks, and one 
with all IBM racks.  The OEM racks (about 7 of them) actually leaned to 
the right (as you were looking at the front)  nearly 1/2 inch. It was 
enough to enable you to visibly detect it.  This was due to the weight 
distribution in them and the way the cables were run over the top.  The 
rails on the servers were useless since with the slight pitch, you could 
not easily get a server in and out anyway.    The IBM racks  -- straight 
as they day they were installed.  Also, IBM racks come with a real man 
tip plate that keeps the rack from coming over on top of you when 
servers are rolled out.  Other racks don't have them.  Significant 
safety feature.

Second and more important reason.  The space allocated on the sides 
allows for proper cable management and room for any of the systems (In 
this case POWER) IBM builds.  Cables are kept out of the way allowing 
proper air flow.  Plenty of space to mount 4 PDUs in the sides out of 
the way, or if you like horizontally at the top or bottom.

Lastly, the real cost of the rack is not list.  It's usually included in 
the order (if needed) and discounted at the same percentages as the 
balance of the equipment.  If you buy OEM racks, the discount may not be 
as good.

APC makes an excellent rack. IBM is actually working with them on 
various cooling solutions and sells the APC racks as well.  You'll see 
them in many of the IBM customer centers.
