VPlex Geo brings disparate storage arrays into a single resource pool and enables petabytes of storage to be made available to production systems over long distances.
LAS VEGAS - EMC is literally
going the distance with its Virtual Storage initiative.
The world's largest storage
and data-security company on May 10 at EMC World 2011 introduced VPlex Geo, an
improvement upon a year-old product that enables terabytes of data inside
non-EMC and non-connected storage systems in geographically dispersed data centers
to be federated and used as a single pool of virtual storage.
Islands of storage currently
have to be located physically within a system to work optimally with processing
servers. Even then, as data center managers will attest, large data sets still
can take hours or days to move and process.
Add miles of physical
distance, which causes latency and additional technical bottlenecks in systems
that aren't designed to work together, and a large workload can be brought to
its knees in no time.
Today, using virtualization
tools from VMware, IBM, Hewlett-Packard, Microsoft and other companies,
businesses can move huge server workloads, but they cannot move terabytes of
stored data nearly as easily.
That's where EMC's VPlex Geo
comes in. The product-available as server-borne software or a physical
appliance-brings those disparate storage arrays into a single resource pool and
enables petabytes of storage to be made available to production systems over
The secret sauce is in EMC's
lightweight, block-level connector protocol that adds only changes to the data
and updates all instances of files wherever they may be.
The VPlex appliances, introduced
in May 2010 at EMC World in Boston
, were the first products in EMC's
Virtual Storage initiative, announced the previous March.
VPlex features Local and
Metro editions, depending upon the size of the IT system. VPlex Local enables
businesses to move large amounts of storage within a single data center; Metro
allows such movement between data centers in distances of about 100 kilometers.
Massive Data Stores Now Available Across Continents
With VPlex Geo, EMC now can
enable access to massive data stores between continents with VPlex Geo.
"We can easily do 2,600 miles today, which is almost the distance across
the United States," Brian Gallagher, president of EMC's Enterprise Storage
Division, told reporters at EMC World 2011.
still-being-developed Global version will enable movement of these stores
throughout the world, Gallagher said.
"When [will it be
available]? Let's just say 'later,'" Gallagher said with a smile.
For starters, VPlex Geo can
work with basic business applications such as Microsoft SQL and SharePoint,
Oracle RAC and SAP in a Hyper-V environment. EMC has lined up a number of other
sanctioned applications for this environment.
VPlex does for virtual
machines what VMware's VMotion does for servers, enabling them to move them
from one place to another-providing new efficiencies without cutting any
lifelines. VPlex enables this using a technique called distributed cache
coherence, gained through its acquisition of YottaYotta in 2008.
The combination of this
technology and global federation eliminates the issues of distance when talking
about data, issues such as latency, bandwidth and resiliency.
In the 12 months since these
appliances have been available, VPlex also has served to enable enterprises to
continue their push to cloud computing, a key part of EMC's message at the show
VPlex Geo is scheduled to be
available this summer, Gallagher said. Other VPlex capabilities will become
available this quarter, he said.
