The following opinion-editorial is written by Ben Muise, Senior
Systems Engineer of Continental
Resources, Inc. (ConRes):
One of the truths of life is nothing great is ever achieved by playing
it safe. Look at Christopher Columbus. It would’ve been easy for him to
say “Hey, you know what? That trade route to India around the Cape of
Good Hope seems to be working alright. Let’s just stick with it.”
Instead, thinking there might be a faster, more direct route to India,
he pointed his ships westward. It seemed to work out pretty well for him.
The world of business and technology is facing a similar dilemma.
Virtualization has become a new hot-button issue for enterprises that
want to improve their computing power while reducing equipment, power
and cooling costs and requirements. The safe route – the Cape of Good
Hope of IT – is to take the servers you own (and/or buy new ones) from
the suppliers you have always purchased from and impose virtualization
on them. It certainly works; there have been plenty of success stories
about the virtues of virtualization.
Yet just because it works doesn’t mean it’s the best option. That’s what
makes Cisco’s Unified Computing System (UCS) so attractive. Rather than
creating a retrofit for existing technology, Cisco started from ground
zero. Instead of saying, “How can we make virtualization work with what
we have?,” Cisco engineers said, “What is the best way to create a
virtual server environment?” The result is a complete re-imagining of
server technology and how it operates in a system.
Take moving an application from one server to another. In a normal data
center environment, moving the entire “personality” of a server – the
MAC address for Ethernet and World Wide Name and Port Name for fibre
channel – is a time-consuming, complex process. It doesn’t matter
whether you’re moving it across the country or across the aisle; it’s
likely going to take 90 to 120 hours to bring up that new server.
With Cisco UCS and UCS Manager, you have the ability to insert an
abstraction layer between the hardware and the user community in a
virtual environment. This abstraction layer makes it possible to move
the MAC address, World Wide Name, Port Name, etc., almost as easily as
you move the data. You can spin up the new server in hours, or at most,
a few weeks.
This ability to move server personalities easily is a huge advantage
both for green field virtual data centers and upgrading existing (brown
field) ones because it gives enterprises the ability to start small and
then increase capacity as your needs grow. You can gain a sense of how
much you can stand up on an individual blade, and if it turns out you’ve
undersized it, you can increase the available CPU count, memory and I/O
port count by moving the personality to a larger blade – creating an
almost instantaneous improvement in application performance. For anyone
in a financial or manufacturing environment, where there is a constant
demand for improved hardware performance, that’s huge.
Another improvement Cisco has made by starting fresh with UCS is a
reduction in the amount of cabling required. Typical servers, of course,
require eight cables. Blades in a Cisco UCS environment require two
cables at most, and often only one. As a result, it’s faster, easier,
and less expensive to build or revamp your virtual data center. Fewer
cables also mean fewer pieces that can deteriorate, get pulled out
accidentally, be mis-wired or otherwise fail. And should a problem arise
at 2:00 AM on a Sunday morning – which is the time these things usually
occur – it’s that much less cable to trace through to find the source.
A good way to think of the Cisco approach is it’s the difference between
designing an airplane and trying to make an automobile fly. Both might
get into the air, but it’s pretty much a given that the purpose-built
airplane will out-perform the flying car.
With any new technology, there are always questions about whether it
will perform as stated. Critics (especially those with their own agenda)
like to point out that the traditional server environment has been
around a long time, while UCS is new, and by implication, unproven. Yet
that’s not the case.
The current technology is already up to what can be considered version
1.3. The kinks have been worked out, and it’s ready for prime time. UCS
has proven both its stability and scalability in real-world
environments. It’s ready to become a difference-maker for enterprises
that want more performance with much greater flexibility in their data
centers.
Of course, as anyone in IT knows, having a great product isn’t enough.
In the complex environment of the data center, you also need expertise
to make it perform to its capabilities. That’s where Continental
Resources shines.
We are one of the few integrators that have earned UCS certification
from Cisco. We already know the in’s and out’s of the technology, and
can help you take advantage of it whether you want to make a gradual
changeover or get a fresh start from the beginning.
Like Columbus, Cisco has chosen to defy conventional wisdom by trying a
new approach rather than simply following the crowd. And also like
Columbus, that bold move has proven itself to be a smart one that is
paying huge dividends to UCS customers.
Instead of settling for a retrofit approach, make your move to
virtualization – one that incorporates forward-thinking: Cisco UCS. It’s
creating a whole new world in data center excellence.
