Welcome to The Virtual Viewpoint: Storage Virtualization - A Contributed Series by DataCore Software
Retailers Take Stock: “Empowerment through Flexibility” Available Today with a Storage Hypervisor Written by DataCore Software President and CEO George
are more than a million retail companies in the United States, ranging
from mom and pop corner stores to large department store chains and big
box stores, not to mention online retailers. At first glance, you’d be
hard pressed to point out what virtually all of them have in common
besides selling merchandise piecemeal to the general public. That is,
until you looked at their bottom line, which is characterized by
razor-thin net profit margins, generally around a couple of percent.
Little wonder that retailers have been among the most aggressive
adopters of server virtualization, seeing in it a way to improve their
bottom line by reducing IT costs and promoting the agility needed to
meet competitive demands. The economic uncertainty of the last few years
and its impact on consumer spending has made this technology even more
strategic for retailers. But as they expand their virtual server
footprint, many retailers find that their storage infrastructure stands
in the way of continued improvement.
That was the case with Thorntons, a company that operates 162 gasoline
and convenience stores, car washes and travel plazas across Kentucky,
Illinois, Indiana, Ohio, Tennessee and soon, Florida. Thorntons dove
into server virtualization in 2007, and now over 90 percent of the
company’s systems are virtualized. But as the company grew—both in terms
of new stores and the applications that support them—its SAN couldn’t
keep up. By 2011, with storage utilization soaring past 80%, performance
was starting to suffer, and it looked like another, large storage
expenditure would be needed.
But Kevin Schmidt, senior network engineer at the company, knew a better
way. He didn’t want to keep just throwing storage at the problem,
especially since that approach wouldn’t leave room in the budget for the
high availability and disaster recovery capabilities that his roadmap
called for. He turned to DataCore partner The Mirazon Group, and the
SANsymphony-V storage hypervisor, which does for storage what VMware
does for servers: managing all storage assets as a single virtual pool.
The benefits were immediate and far-reaching.
When interviewed previously this year, Schmidt stated, “The deployment
of SANsymphony-V not only boosted overall systems performance, but
basically paid for our high availability deployment and gave us a huge
boost towards a full disaster recovery site. It was a significant
savings overall and put us in much better shape to keep our
infrastructure solid and enhance our productivity.”
SANsymphony’s RAM cache vastly decreased latency for all of Thorntons’
storage, resulting not only in faster application performance but also
much faster backups. A monthly profit and loss report that used to take
9-10 hours to run now only takes 3.5 hours, and overall backup time,
whether for VMs, SQL databases, or a full system backup, was reduced by
Even more important, by boosting the performance and utilization of both
the new SAN and the old one, SANsymphony-V made it possible to
repurpose the old SAN as the target of DataCore’s synchronous mirroring
capabilities, providing the non-stop high availability demanding by the
chain’s stores, which operate around the clock. The old SAN was moved to
another site on the Thornton campus, linked to the primary storage by
8-gigabit Fibre Channel. If primary storage fails, the secondary site
takes over immediately, with no effect on applications or users. The
next step will see this site upgraded with additional VMware ESX servers
to provide full disaster recovery capabilities, so that even if the
primary servers go down, operations can continue.
