| Hollywood movies
are increasingly computer-generated. Big-budget pictures use effects in
every shot, but more modest films have started using CG imagery as well,
to reduce costs. As a result, post-production houses are under constant
pressure to increase capacity while also keeping up with the very latest
technical advances – putting huge demands on their data storage.
That’s why one post-production company
turned to Nexsan, the leader in innovative storage technology.
The chamber of
secrets
The Moving Picture Company (MPC) is
one of the world’s leading post-production houses, based in Soho, London.
Building on over 30 years’ experience in the advertising, television and
music industries, MPC is now a pre-eminent name in feature film effects,
recognised on both sides of the Atlantic.
MPC’s artists and technicians have created
some of the most spectacular scenes ever committed to celluloid, with recent
projects including Troy, Alien Vs. Predator, Big Fish,
Ella Enchanted and Harry Potter and the Prisoner of Azkaban.
However, it isn’t just epics and fantasies
that call for the MPC touch. Even ‘straightforward’ contemporary films,
such as Working Title’s Wimbledon, are using digital effects for
crowd shots and to simulate complex camera moves.
As the diversity and sophistication
of CGI increases, MPC must strive to meet – and encourage – demand for
new effects. Cutting-edge ideas soon become old hat, so if MPC is to remain
competitive, it has to keep pushing the boundaries of imagination and technology.
The sorcerer’s stone
Leading the push is Steve MacPherson,
Head of Technical Operations in MPC’s film division. Steve has worked in
the computer industry for almost 20 years, which included a period at Silicon
Graphics Inc. where he first crossed over into the movie world. Although
Steve spent a couple of short spells working with MPC earlier in his career,
he only took up his current role in June 2003.
Steve’s primary responsibility is running
the MPC machine room: a huge storage facility and render farm with a 100TB
capacity. Of that, around 40TB is dedicated to film work.
Just over four years ago, MPC made the
decision to move from Silicon Graphics technology to an Intel/Linux-based
solution. At the same time, they decided to investigate new ways of storing
and processing the vast amounts of data that their work generates.
Their investigation led them to Andy
Wray at Nexsan reseller Boxer Systems. Andy recommended that they tried
the Nexsan ATAboy RAID array – and MPC has used Nexsan products ever since.
“Storage is pretty much a commodity
to us – but Nexsan has proved to be so reliable over the past four years,
and at such an attractive combination of price and performance, that it’s
become the bedrock of our storage system.”- Steve MacPherson, MPC
Enchanted
Having upgraded to the ATAboy2, Steve
now runs an extremely flexible hierarchy that allows him to allocate varying
levels of storage and processing power to different projects, using MPC’s
own in-house software.
Each film project has a number of servers
assigned to it, depending on how much capacity it requires. All the servers
are attached to an Ethernet backbone. Via an edge switch, the servers can
be connected directly to any part of the thousand-processor render farm.
The balanced architecture of the network means that there is just enough
storage capacity to feed the voracious render boxes.
The high-capacity Nexsan arrays predominantly
store image data: namely DPX, Cineon and TIF files. They also hold
Job Description Files (JDFs) created by the advanced graphics applications
employed at MPC. A large amount of storage space goes to application caching,
mainly for 3D effects – many gigabytes of geometric data are generated
and saved for future operations.
At any given moment, twenty or more
artists can be working on different aspects of the same shot or sequence,
making multiple passes, amending and rendering as they go. The network
needs to be able to cope with all of these parallel, data-intensive operations
– without impeding performance. With Hollywood deadlines, time is always
tight, and Steve has to ensure that any hitches are anticipated and eliminated.
The Nexsan ATAboy2s are a vital part of that.
“My job is to make sure that all our
operators have the resources they require, all the time. We can’t afford
to have a server go down, ever, but at least I know the Nexsan systems
will always be available. It means I worry slightly less.”- Steve MacPherson,
MPC
Big fish
The future of MPC looks bright, with
their work dazzling people in cinemas around the world. The company has
gained a tremendous reputation in the film industry and there are plans
for expansion. But success brings its own challenges.
“We offer greater computing power to
our artists, who use that to create fantastic new effects, which audiences
love – but then they want to see the next new thing, so we have to step
up capacity again. It’s like a feedback loop: we always need to increase
the amplitude, without distortion. Scaling capacity with Nexsan storage
helps make that process seamless. ”- Steve MacPherson, MPC
Faced with the movie-going public’s
insatiable hunger for bigger and better effects, Steve is glad to have
had a solid, scalable foundation for the MPC architecture, enabling it
to grow. Just a few months on from the last upgrade, Steve is already thinking
about the future – and with Nexsan’s help, he can be sure that MPC will
be keeping audiences spellbound for years to come.
