Background
JCB are one of the world's top three
manufacturers of construction equipment, employing over 8,000
people in factories spread across four continents and with
operations in over 150 countries. In the UK their name has become
synonymous with engineering vehicles as a whole, to the point that
the term can be found in the Oxford English Dictionary.
Problem
Like any company, JCB spends a lot of money each year on
marketing. A part of this marketing involves
computer-rendered digital images of various JCB
designs, created using LightWave 3D graphics
program. However, JCB had only one computer
on-site dedicated to rendering the images and this was
also being used by the 3D designer for other purposes. The result
was that image rendering would take several days, even a week,
during which time the computer could not be used for anything else.
Because of this it was becoming increasingly difficult to
maintain a sufficient work rate and to meet deadlines.
What was needed was a solution that could achieve the
following:
- Reduced rendering times to speed up turnover of images.
- The ability to be working on a machine while the rendering is
occurring in the background.
- Maximum potential and minimum disturbance to the rest of the
network through its own dedicated computers.
- Adherence to JCB's existing security policies.
Solution
JCB consulted with Jigsaw about the best solution. Installing a
render farm would provide the answer to JCB's
problems and various options were looked at before a decision was
reached. It was decided that the best option was to install a
Muster render farm with an edit
station and six Xserve servers as render
nodes, alongside six more nodes on Mac Pros that JCB
already had and wished to use. During pre-installation testing
Muster was found to be incompatible with the Mac-based Lightwave
software so the render farm was switched to
Screamernet instead.
This solution met all the requirements JCB had for the new
system, offering a significant performance increase at a price
within their budget.

Implementation
JCB already had some of the required equipment on-site,
including the six Mac Pros and a rack mount for the servers. The
rest of the equipment was delivered first to Jigsaw, where much of
the set-up work on the Xserve servers and edit station was done
before it was transported to the site for installation,
thus speeding up the actual time needed on-site and
minimising disruption caused by the installations.
It is also at this time that checks are run to ensure the
equipment works and that the software is functioning and
compatible. This allows unexpected problems to be spotted before
installation has been completed and therefore makes corrections
smoother and quicker.
The on-site installation itself took only two
days, partly because JCB was able to set up the Mac Pros
and install the necessary security software beforehand, preparing
the way for the Jigsaw engineers.
Benefits
There were two primary benefits as a result. Primarily, the
render farm means a lot more processing power is available to be
used for rendering the designs, meaning shorter rendering
times and higher quality. In addition, the presence of
dedicated servers instead of a single overworked CPU means
designers will no longer suffer from the downtime brought about
while an image was being rendered, when they were previously unable
to use their computer.
Beyond these, though, the decision to also install six Mac Pros
as additional nodes allows for even greater processing
power to be drawn upon when necessary by shifting these
nodes to work with the servers. This can also easily be done during
evenings and weekends when they would otherwise be idle. Finally
these Mac Pros mean greater access to the rendering
system, as now more than one workstation is connected to
the rendering data and hardware.
Summary
JCB required a means to more efficiently render their digital
design images and enhance their effectiveness through the use of a
dedicated rendering system. Jigsaw was able to provide this through
the installation of a full render farm with dedicated servers,
providing them with a new system that met their requirements for
performance and functionality while not exceeding their budget.
The possibility of upgrades to the render farm in the future
remains, with changes from simple software upgrades to the
expansion of the hardware itself (such as the addition of further
servers to boost the power of the render farm) all being
viable.
Deciding on the exact render farm for your needs isn't a simple
'compare the numbers' exercise. It's more often a matter of looking
at the individual requirements and getting expert technical help
for that particular case.
