Server virtualization technology over the last decade has remade the data center.
Enabling x86 computers to run multiple operating systems and applications — and
separating logical servers from the physical boxes on which they run — virtualization has
made IT infrastructure simpler, more automated and more efficient.
Server virtualization has saved IT billions of dollars on both capital and operating
expenses by relying on fewer physical servers, but ones that are more efficient and being
used to the max. That means data centers don’t have to be as big, which saves on power
and cooling. Server virtualization has also made data centers more reliable and better
equipped to enable IT to recover from disasters. Just as important, server virtualization
has been a key enabler in the inexorable march to cloud-computing infrastructures,
whether they be public, private or hybrid models.
Clearly, the benefits of server virtualization have been substantial, and they’re ongoing.
But even as improving technology continues to add benefits, they’re beginning to run into
inherent limits. Server virtualization is only the first step to fundamentally transforming
the data center. Enterprises need to address all the other layers of data-center operations
to complete the transformation.
The question then becomes, where do we go from here?
Server virtualization will continue to deliver
incremental improvements, the same way
carmakers offer faster, better- handling,
more efficient cars with each new model
year. Server virtualization is just one aspect
of creating the next-generation data center.
To create a truly better car, or a truly better
data center, you need to look at all the
elements, not just continued, incremental
improvements in the areas where you’re
already making progress.

Virtualization As We’ve Known It

The next generation of virtualization opportunities won’t just be more of the same, but will
extend the benefits of abstracting hardware to homogeneous pools of physical devices
and then slice and dice them as needed for optimal use throughout the data center. Just as
modern car buyers increasingly value new functionality like integrated satellite navigation
systems, digital infotainment and telematics systems over pure performance, the future of
virtualization lies in bringing greater efficiency and intelligence to networks, applications and
storage to create a truly software-defined data center.

Virtualization As We’ve Known It

The widespread adoption of server virtualization has revolutionized the provisioning and
management of computing power, saving enterprises billions of dollars. However, the rest of
the data center has not kept pace with those advancements.
As businesses bump up against bottlenecks in IT systems, they’re looking to virtualize
networks, applications and storage to open the path to simplified, automated, less-expensive
data centers. Trends such as Software-as-a-Service (SaaS), big data, mobile computing and
Bring Your Own Device (BYOD) are raising business expectations about what technology
can do, forcing IT to embrace new paradigms to avoid being left behind.
As businesses take full advantage of the low-hanging fruit of server virtualization’s relatively
easy implementation and now-obvious benefits, they can use that success as a proof
of concept for extending the approach throughout the data center. The next three big
opportunities for virtualization in the enterprise include:
1. Network virtualization
2. Application virtualization
3. Storage virtualization
Network virtualization becomes a priority when the enterprise no longer finds it acceptable
to wait weeks to manually provision new workloads with network connectivity or change
network configurations. It becomes essential when the network needs to quickly scale and
the enterprise can’t afford needlessly expensive
proprietary hardware.
It’s time to implement application virtualization
when scheduled downtime for mission-critical
software is no longer acceptable, much less the
risk of not having access to those applications in
the event of a disaster. Application virtualization
often finds its first toehold when new application-
development projects need to be rapidly tested.

Meanwhile, even though the cost per unit of storage continues to fall, the rise of big
data encourages enterprises to store more and more information. That makes storage
virtualization’s cost savings an increasingly attractive option.

By creating a complete software-driven abstraction layer that reproduces a physical
network, network virtualization — sometimes referred to as software-defined networking,
although they’re not precisely the same — does everything a physical network can do, but
with the same kinds of operational benefits and hardware independence that transformed
the world of servers.
By decoupling networking components from the underlying physical
infrastructure, organizations can rapidly provision and configure
networks of any size and complexity without having to run out and
touch the physical switches, ports and routers. Remote management
and monitoring allows for greater control and visibility into what’s
going on across the network, which can boost security by preventing
unauthorized nodes from accessing sensitive data.
All of this automation frees IT administrators from wasting time on
repetitive, manual drudgery, and reduces human errors that can slow
performance or even cause network outages.
Virtual networking can also cut capital costs by turning the physical
network into a simple packet-forwarding backplane running on
inexpensive, industry-standard commodity hardware — helping to
avoid proprietary vendor lock-ins.

Running enterprise applications such as databases, ERP, CRM, email, collaboration, Java
middleware and business intelligence on virtual machines promises a variety of benefits.
They include increased standardization, better availability with less scheduled downtime and
simplified disaster recovery. Of course, the cost savings that come from
consolidating infrastructure can also be significant.
Virtualized applications also make it easier to manage performance and
capacity, improving quality of life for technicians by allowing scheduled
maintenance to be done anytime without taking the apps offline.
Virtualization also offers a more reliable and realistic testing environment
that helps speed complex development projects.
The biggest benefits, of course, come with virtualizing the most important
Tier 1 applications, along with proprietary applications for specific
industries. IT leaders are often wary of moving these mission-critical
applications to virtual machines, but technical advances and performance
improvements continue to lower the risk.

Like other kinds of virtualization, storage
virtualization abstracts storage resources from the
physical devices to create a pool of flexible, efficient,
reliable and highly scalable shared storage for
virtual machines. Pooling of inexpensive industry-
standard commodity hardware allows storage to be
automatically addressed, managed and optimized
regardless of the type — solid-state drives and hard
disk drives — or physical location.
Storage virtualization can save up to 50 percent in
storage TCO, a critical advantage as the rise of big
data leads enterprises to store ever-larger amounts
of data, even if they’re not yet sure how they plan to
actually use all that information.
A fundamentally better way to manage storage resources, storage virtualization
dramatically reduces the capital and operational cost and complexity of storage
infrastructure.
Enhance Access With Simplified Storage
5 benefits of storage virtualization
1. Improve storage resource utilization and flexibility to reduce
wasted storage.
2. Enable provisioning that is rapid and dynamic, spinning up
storage as fast as a virtual machine.
3. Simplify storage management, including automatic replication
and de-duplication.
4. Simplify day-to-day IT operations, including OS patching and
driver requirements.
5. Increase application uptime.

The speed of business is moving faster than ever. Growing at an amazing pace, server
virtualization has moved key components of IT infrastructure into the fast lane, but many
other areas are stuck in traffic and simply not
keeping up.
Applying virtualization to the network, storage
and applications is the single most effective way
to reduce IT expenses while boosting efficiency
and agility. Enterprises — and small and midsize
businesses, too — want to move away from a reliance
on expensive proprietary hardware throughout their
IT infrastructure, and virtualization has proven to be
the best way to do that.
It simply does not make sense to limit virtualization’s
benefits of lowered costs and increased scalability to
computing power alone. The technology is in place.
The needs and benefits are clear.
The time is right to implement the next generation of
virtualization — in networking, in tier-one applications and in
storage — key elements of the software-defined data center.
