PHOTO As part of its revamped infrastructure strategy, Cisco is installing
cabling in a new way. As the emphasis is on flexibility in an
architecture moving towards full virtualisation, it makes sense to make
the cabling flexible too.
Traditional data centre cabling runs under the floors and most IT
professionals will admit that the biggest pain in moving systems is
moving the cabling. Cisco now runs cables over rather than under the
floor, in the yellow ducts shown here.
This makes it easier to re-configure the room’s devices and makes
everything easier to see. It looks odd, but IT staff who are spared
from having to scramble around floors tugging cables through conduits
are unlikely to complain about aesthetics.
Another benefit is in heat distribution. Data centres run hot in
certain parts and cool in others, which leads to poor heat
distribution. According to Cisco’s managers, finding power is not a
problem but dissipating its by-product, heat, is. Cables that run over,
now under, data systems are now recommended as better distributor of
heat.
Now, who said that cabling was boring?
