IBM Systems Magazine, Power Systems - July 2017 - 29
Seeking a better alternative, the
retailer ran a proof of concept to
see if a Linux on POWER system
would improve performance of
the batch job. It did. The batch
job was executed 12 times faster
on the POWER platform with only
10 percent CPU utilization. Tasks
that previously took more than
24 hours to run on x86 are now
completed in less than one hour.
The retailer employs POWER8
E870 systems running Red Hat
Enterprise Linux. Migration of
the MongoDB database from x86
to POWER was quick, easy and
completed in just one business day.
Organizations must consider a
number of factors when deciding
on a platform. They need to
understand their current and
future workload characteristics
and the infrastructure needed
to support them, Garvin says. If
that analysis isn't done properly
and without bias, a company
may find itself saddled with a
system that doesn't work and
If your current POWER system
has been running well with
no performance, reliability or
scalability issues, then tread
carefully before deciding to switch
to x86, which may turn out to
be more costly and difficult to
manage, Garvin says.
IBM Power Systems can
handle open-source applications
and Linux, so x86 isn't the
only system to consider.
SAP HANA and open-source
database applications have seen
tremendous performance benefits
when run on a POWER platform
versus x86. That's another reason
to do some comparison shopping
before buying a "good enough"
server that doesn't perform well.
"Infrastructure does matter,"
Organizations will benefit
from exercising due diligence on
any platform being considered.
A cheaper platform might not
be robust enough, resulting in a
costly reimplementation. "Anyone
with fiduciary responsibilities
needs to look very hard at
the POWER platform or risk
investing the company's money
in a solution that may have to be
replaced," he explains.
