Is data center consolidation causing bloating and congestion?

doctor and patientIf you answered “yes,” well, I’ve got the remedy.

If your enterprise is feeling the ill effects of poor WAN performance, you may assume it’s a bandwidth problem. If you invested in more bandwidth and a bigger pipe to ease the pain, and the problem persisted, the problem may be due to packet loss, latency or bandwidth-hungry applications, such as streaming video.

If you’re like me, when you’re feeling sick and the basic medicines aren’t helping, sometimes a doctor that knows far more about the issue can help relieve the problem. Similarly, if you are responsible for ensuring your WAN’s reliability and performance, you may be frustrated by not having insights into the underlying limitations of your network. But, with the right tools and visibility, you can make a much more informed decision in dealing with your WAN capacity issues.

There’s no question that data center consolidation can save significant capital and operating expenses. Data center consolidation can dramatically save deployment, maintenance and support costs by reducing the number of servers and remote IT staff — and by lowering IT infrastructure complexity. Many enterprises will modify and consolidate redundant data center facilities to reduce costs associated with power, cooling, efficiency and space.

Consolidation brings congestion

Network IT personnel should be able to implement data center infrastructure so it makes the most business sense, without worrying about the impact that WAN performance will have on remote user productivity. However, that’s not always the case. With all the benefits data center consolidation brings, it puts additional strain on the WAN, as increasing amounts of traffic must pass between the data center and remote and mobile workers. Inevitably, this leads to poor application performance and slow response times for branch offices, telecommuters and mobile workers.

While the Internet, VPNs, and MPLS networks have many advantages, they also have inherent problems. In this case, the benefits rendered by data center consolidation are now causing new problems that affect user productivity, business communications and commerce.

WAN optimization solutions have become essential for data center consolidation and data migration. Data center-class WANop solutions are capable of reducing network bloat by eliminating over 95% of unnecessary and redundant traffic using disk-based de-duplication and compression. Enterprises can use WAN optimization to consolidate data and IT resources within fewer data centers – eliminating the need to upgrade WAN capacity in those locations. WANop allows large data transfers over the existing networks, which is vital for data migration. By enabling massive amounts of data to be moved to new locations quickly and cost effectively, enterprises can avoid additional monthly costs to upgrade existing bandwidth.

By localizing content delivery, and coupling it with latency mitigation techniques such as TCP and CIFS acceleration, enterprises can ensure all centralized applications work across the WAN — with LAN-like performance. To further reduce network bloating and congestion, WANop solutions can alleviate network performance challenges due to packet loss that is common with the Internet, IP VPNs and MPLS networks.

WAN optimization vendors, and Silver Peak in particular, have adaptive Forward Error Correction (FEC) and real-time Packet Order Correction (POC) technologies that improve WAN quality by ensuring traffic is delivered reliably, without requiring additional packets to be sent to compensate for lost packets.

When resources are consolidated within data centers, congestion becomes a very tangible problem. WAN optimization can address this with quality-of-service (QoS) to ensure essential applications are not adversely impacted by non-critical applications, and real-time traffic is prioritized for optimal performance.

Network relief for IT personnel

Data center consolidation can affect all users, as they now contend for shared resources. This is particularly true for remote users located farther away from centralized servers and storage. These users can experience inconsistent, unreliable and slow application response time.

To keep network IT personnel from having upset stomachs caused by WAN problems and calls from disgruntled users, look into how WAN optimization can help alleviate WAN pain associated with data center consolidation.

Is your WAN caught in a Catch-22?

WAN-Catch-22You may or may not remember “Catch-22,” the novel published in 1961 by Joseph Heller. Since then, Catch-22 has become a term generally used to describe a “no-win situation,” in which there is no positive outcome from any decision you make. Whether due to unavoidable or unforeseeable circumstances — or outside influences — Catch-22 situations are never fun.

When it comes to your organization’s wide area network (WAN), you may be facing a Catch-22 situation right now. In managing your WAN infrastructure, you may be challenged because of efforts to consolidate your data centers in the interest of lowering costs and complexity.

With data center consolidation in particular, not only do you have to consolidate the equipment of two sites into one single location, but you’re also now faced with more network traffic in and out of the newly consolidated data center.  The result? Users may complain about slow applications, and the network that you count on to deliver your applications becomes unreliable.

Don’t Be a Victim

Let’s examine the common solutions to this problem: One the one hand, you can add more bandwidth, but this can get extremely expensive–even cost-prohibitive for all but the largest of corporations.  But let’s be honest, you can chase your tail adding bandwidth.

Depending on your environment, you may be bringing more servers online to support the added traffic, as well as adding applications to support the data center consolidation initiative, some of which may be more impacted by WAN quality than WAN bandwidth.  VDI comes to mind.

WAN Optimization to the Rescue!

Fortunately, WAN optimization appliances can help you avoid a Catch-22 situation in your data center consolidation efforts. WANop solutions help alleviate bandwidth congestion by reducing the amount of traffic that goes across the network using a combination of data compression, de-duplication and transmission optimization technologies. Additional quality of service (QoS) technologies can be used to make application delivery more reliable when traversing networks that are not directly under your control. In some cases, WAN optimization can result in a 20:1 reduction in traffic and a 10:1 reduction in WAN costs.

The benefits of WAN optimization don’t stop there. If you’re replicating data between your newly consolidated data center and a disaster recovery (DR) site, WAN optimization can be a huge lifesaver. You may have hundreds of gigabytes of data residing in distributed file systems, distributed databases, cloud computing platforms, or scalable storage systems. And due to the inherent nature of large volumes of data, and the distance between sites, data replication without WAN optimization can either be impossible to carry out, or can be a nightmare to manage and support.

Using WAN optimization, you are better positioned to support a data center consolidation project or support the addition of a disaster recovery site using either your existing WAN infrastructure, or investing in a lower-cost, lower quality WAN.

WAN Optimization: Balancing Green with the Need for Speed

Green data centerAh, data center consolidation: the vehicle by which today’s businesses may achieve “Green” status. The many Green benefits of data center consolidation have been hashed and rehashed, blogged about and discussed, hailed and revered so much so that they are forever burned into our minds to the point where even the government has gone out of its way to seek energy efficiency through data center consolidation.

Certainly, energy efficiency and lower operating costs are among the benefits, as is attaining a competitive edge over non-Green competitors. And while we’re at it, let’s talk about the tax breaks for Green companies. In our April 15 blog “Going Green for Green“, we talked about the incentives initiated by former President George W. Bush and later amplified by the Obama administration. For the welfare of our planet and wallets, it’s good to be Green.

But, as Kermit the Frog used to say, “It isn’t easy being green.” While data center consolidation and the accompanying Green distinction present a financial boon and a reputation boost to companies of all sizes, it can also compromise efficiency for remote users accessing applications. Users tapping the centralized servers and storage located in close proximity to a branch office will no doubt experience LAN-like performance. But move the data center elsewhere to consolidate — and Greenify — and application performance goes down the tubes along with overall remote user productivity. Unless companies are willing to shell out big bucks for more bandwidth, latency will rule and WAN performance will suffer.

So how does a company balance a need for speed with its endeavor to be Green and cost-effective through data consolidation? There are really only a couple of choices: stick with what you’ve got and watch productivity lag or throw your WAN (and remote workers) a lifeline by using the most advanced WAN optimization technologies.

Silver Peak is at the cutting edge of WAN optimization technology, and its solutions aim to deliver LAN-like performance regardless of branch office proximity to the data center. It achieves this through a number of innovations and unique approaches. Network Memory™, for one, is Silver Peak’s WAN deduplication technology, used to inspect all inbound and outbound WAN traffic in real-time, storing a single local instance of data on each appliance. Essentially, it maximizes WAN bandwidth and lowers WAN expenditure.

Silver Peak also employs latency mitigation techniques to ensure all centralized applications work across the WAN with LAN-like performance, employing local information delivery whenever possible. Packet loss, which can dramatically affect performance, is also addressed with Silver Peak’s Network Integrity features, dramatically improving WAN quality.

The bottom line is that businesses can reap all the benefits of going Green with data consolidation without bowing under the backlash of latency and poor performance. And with this week’s announcement of VX-Xpress, a free, fully functional WAN optimization virtual appliance, and VRX-8, the industry’s highest capacity WAN optimization appliance, companies of all sizes and at all points of WAN optimization utilization – from entry-level to maxed out – can improve their WAN performance and go Green at the same time.

Do you have a BSD? Then you need NX-10K!

With the launch of the industry’s highest capacity WAN optimization appliance, the Silver Peak NX-10K, we are occasionally asked – who needs a device with so much capacity?  The answer is simple – anyone with a Big Strategic Datacenter (BSD).

Do you need to move large volumes of data for business continuity or disaster recovery? Do you have hundreds of remote sites accessing servers from a centralized location? Are you deploying a managed service or cloud offering over a high capacity backbone? If so, odds are that you have one — or even several — BSDs and the NX-10K is for you.

We know how challenging and expensive it can be to own and operate a BSD.  With the new NX-10K, life just got a whole lot easier.

Going Green for Green

It’s April 15 again, and to every adult citizen of the U.S. that means one thing – income tax deadline!

This year, individual taxpayers get a reprieve of a few days, until Monday, April 18, to file their taxes because Washington D.C. celebrates Emancipation Day today. Meanwhile, businesses across the country still have a few months to think about filing their corporate returns. As they do, they may be looking for a reprieve of their own, only theirs comes in the form of tax incentives for “Going Green.”

In 2005, former President George W. Bush signed into law a tax incentive plan that provided a deduction for companies and building owners that enacted plans to reduce heating, cooling, lighting and energy costs. That break helped to reduce companies’ taxable income, so owners got back a percentage of what they spent on implementing sustainable systems. However, these same incentives now stand to become an even bigger boon to business and property owners as the Obama administration moves to change them from deductions to credits. This means the dollars spent will directly reduce the amount of tax owed (or increase a refund) on a dollar-for-dollar basis or close to it.

Grassroots Green

For many companies, trying to qualify for these tax credits will require a good bit of retrofitting existing systems.  They will seek out ways to reduce their carbon footprint through energy use reductions and find methods to cut back on the number of hardware items – servers, routers, et al – used in their data closets. There’s one limiting caveat behind all of these efforts, though. Not only can the reduced power and physical footprint not detract from the current service being provided, but also it has to allow for growth, because as we all know, business data grows exponentially every year. If the “Green” data center doesn’t allow for growth, the tax credits won’t outweigh the inconvenience.

Some companies are going back to square one and building brand new, Green-conscious data centers from the ground up. Arthur Cole over at IT Business Edge has some good tips for companies looking to take this route to Green Data Centers. He discusses keys to making a Green data center plan work including verifying the local power infrastructure and ensuring that allowances for vertical scalability are incorporated. He notes that the initial investment for a Green, sustainable data center will be higher than just adding servers and more cable, but “the longer that solution is in place, the greater the return on that initial investment.”

The list of companies going Green is as long as it is impressive. In fact, Charlie Babcock at InformationWeek reports there is a virtual contest of sorts being waged between giants like Facebook, Google, Amazon.com to see who can build the largest data center that consumes the least amount of energy.

It isn’t Easy Being Green

Not everybody has the resources of Facebook, Google and Amazon.com. Nevertheless, over the next five years, 70% of enterprises will move or significantly modify their data center facilities to conserve on power, cooling and space. Sure, these efficiencies will pay for themselves over time if Congress and President Obama sign the proposed tax credits into law. But even today, eliminating redundant facilities can provide savings to companies in the form of lower facility costs and reduced operational expenditures.

This has elevated data center consolidation to the top of most CIO agendas, but it also presents performance challenges as users vie for shared resources.  In addition, remote users that are far away from centralized servers and storage can experience inconsistent, unreliable and overall disappointing application performance, while data migration further adds to the challenges.

This begs the question, “How can enormous volumes of data be moved to new locations quickly and cost effectively?”

Silver Peak’s WAN optimization solution is strategic to data center consolidation and data migration initiatives.  With Silver Peak’s NX, VX and VRX appliances, enterprises receive the following benefits:

  • Maximize WAN bandwidth / Lower WAN expenditures: Reduces over 95% of WAN traffic through disk based WAN deduplication and compression, enabling enterprises to consolidate data and resources within fewer data centers without upgrading WAN capacity. It also enables large transfers to take place over existing network infrastructure, which is vital for data migration.
  • Optimize application performance: Local information delivery coupled with latency mitigation techniques ensure that all centralized applications work across the WAN with LAN-like performance, and performance challenges that come from packet loss across the WAN, as is often the case with Internet VPNs and MPLS, are addressed. Mitigating WAN latency and loss overcomes the single biggest challenge to data center consolidation – poor application performance for remote users.
  • Manage shared resources: Robust QoS tools ensure critical applications are not starved and that real-time traffic is prioritized for optimal performance.

With Silver Peak, enterprises can put data centers where they make the most business sense without worrying about the impact that WAN performance has on remote user productivity.  In addition, data centers become operational quicker, and operate more cost effectively while taking advantage of the financial incentives for going Green.
