  • Welcome. Today, we are going to present information and concepts designed to help IT organizations use novel techniques to reduce the cost of owning the network edge, and increase accessibility to meet evolving demands. In essence, we are here to discuss “Rightsizing Your Network Edge.”
  • First, we will look at the technical reasons and financial implications of the “Rightsizing Opportunity.”Second, we will examine how Aruba’s solutions deliver a “Unique Technology Advantage.”Finally, we will speak briefly about the strengths of “Aruba as a Business Partner.”
  • KEY MESSAGE: IN THE CURRENT ECONOMIC CLIMATE, I.T. IS IN A BIND BECAUSE IT MUST CUT COSTS WHILE DELIVERING MOBILITY SERVICES TO IMPROVE PRODUCTIVITY. In the current economic climate, IT organizations face difficult challenges. IT budgets are flat, if they’re lucky, or more likely going down. They are being asked to choose which needed applications and capabilities to defer or cut entirely. At the same time, the overall organization is short of staff. Whether they have had layoffs or hiring delays, most organizations need to get more productivity out of an undersized workforce. Consequently, users are demanding more mobile applications because they increase productivity. How can IT meet these needs? IT cannot solve this problem using the ‘same old’ strategy and methods. They need a new strategy to deliver both mobility and cost reduction.
  • KEY MESSAGE: THE WIRED NETWORK EDGE IS INHERENTLY INEFFICIENT AND COSTS TOO MUCH… NOT BECAUSE I.T. HAS MADE POOR DECISIONS, BUT BECAUSE WIRED NETWORK TECHNOLOGY REQUIRES OVER-SPENDING AND EXCESS CAPACITY.If we look at the traditional way network connectivity has been delivered, we immediately see inefficiencies. Underneath most desks you will find 2-4 Ethernet ports, mostly idle. Think about the typical applications users run. Web applications run well on 1-2 Mbps, as do virtualized applications which are basically screen scrapes, much like streaming media. Microsoft Office files can be easily downloaded with 1-2 Mbps speed. Except for some corner cases, such as engineers with large CAD files, or graphic artists with large images, most users can get by fine with just 1-3% of the typical 100 Mbps cable.How much do organizations pay for each cable pull or drop? $200 is a fairly common amount. Organizations usually pull more cable than they need because it is so costly and time consuming to pull additional cables later.When you get to the wiring closet, these cables plug into large switches, which typically have 48 ports. Again there is more waste. If you have 100 cables, you can’t buy 2.1 switches, so you have to round up, ensuring the closet is almost always overbuilt. These switches typically have 15% maintenance, awkward VLAN security administration, and whenever users need to do “Moves, Adds, or Changes,” there is extra cost and labor associated with activating, deactivating and troubleshooting ports. When it is time to do hardware refresh on these switches, the wired vendor usually pushes GigE-capable switches to “future-proof” your network, even though your users don’t use much of the 100 Mbps they have today, let alone a 1,000 Mbps.What we see, is that there is excess and unused capacity gets magnified at almost every stage. The wired network edge is costly, and the costs continue every year after purchase.
  • KEY MESSAGE: MOST ORGANIZATIONS WILL HAVE SEVERAL WINDOWS OF OPPORTUNITY WHERE IT IS EASIER, FASTER AND MORE FINANICIALLY BENEFICIAL TO SHIFT A SIGNIFICANT PORTION OF USERS TO A “PRIMARILY WIRELESS” ACCESS MODEL.When are the key opportunities to save money and increase accessibility by rightsizing your network?While economizing is always a good idea, there are certain common activities that provide additional synergy for network rightsizing.When building out a greenfield network, that would require pulling new cables, WLAN can provide day-1 savings. A wireless card for a desktop PC is typically about $35. Pulling 3-4 cables is typically $600-$800.Additionally, when an organization is coming up on it’s wiring closet refresh, typically performed every 4 to 6 years, network rightsizing can often reduce the closet costs by thousands of dollars.When an organization is reorganizing, and converting more cubicles into a shared pool, also known as hoteling, Network Edge rightsizing can reduce upfront and ongoing costs.When a large group of users will move to another set of already-built cubicles, Network Edge rightsizing can dramatically lower the IT costs of the move.When IT budgets are being cut, Network Edge Rightsizing can reduce the ongoing costs of the existing wired network edge, and in some cases completely pay for Pervasive 11n WLAN while lowering IT budgets in the first year.When new applications are requiring you to expand your network access, Network Edge Rightsizing may allow you to liberate budget to pay for the network expansion.
  • KEY MESSAGE: NETWORK RIGHTSIZING IS THE ONLY WAY TO SOLVE IT’S DILEMMA To ‘right-size’ the network, you need to:Shift users to the least-cost access method that meets their needs. A wireless access point is significantly less expensive than a switch, so wireless will typically be a more cost-effective alternative for users of WiFi-enabled devices. For users that have desktop PCs or require greater throughput than wireless can deliver, a wired infrastructure is still necessary… But for an increasing number of users, a wired connection is a luxury rather than a necessity. The center of gravity on the network is shifting inevitably away from wired to wireless… which presents IT with a great opportunity. Eliminate unnecessary infrastructure… if you have an opportunity to reduce the number of switches you need to support, do it. The more users you convert to primarily wireless access, the more of your old switches you can decommission.To maximize the cost reduction requires simplification. The approach should require IT to make as few changes to the underlying infrastructure as possible. Aruba’s architecture is ideally suited for this – allowing IT to deliver cost-savings without having to re-engineer the entire network. Aruba include Adaptive Radio Management 2.0 and other intelligent self-optimizing to improve reliability and reduce complexity of enterprise WLAN.Of course, none of that works unless the user experience is acceptable.
  • KEY MESSAGE: ONCE YOU MIGRATE USERS TO A WIRELESS NETWORK, YOUR NEED FOR SWITCH CAPACITY DECREASES SIGNIFICANTLY, ALLOWING YOU TO CONSOLIDATE YOUR INFRASTRUCTUREThis “before” and “after” illustration shows how migrating to wireless can reduce the number of switch ports (and switches) by 50% or more for a given population of users… even without migration to wireless VOIP. This illustration assumes that the easier users to migrate, laptop users, and the easy ports to migrate (conference rooms), and unused ports can be reclaimed by providing that same network access via WLAN.The key efficiency is that WLAN does not require a 1:1 ratio of ports to devices, and that flexibility makes it much more affordable to deliver current and future connectivity in a given area.
  • KEY MESSAGE: WIRELESS IS INHERENTLY A MUCH LOWER-COST ALTERNATIVE TO WIRED NETWORK ACCESS. SHIFTING A USER FROM A WIRED PORT TO A WIRELESS NETWORK SAVES MONEY.If IT is looking for opportunities to drive excess costs out of the network, the wiring closet is a good place to start. For years, risk-averse IT organizations have been overbuilding their networks to support anticipated future needs rather than their immediate requirements (the “if you build it, they will come” philosophy”). In fairness to IT, this strategy was necessitated by the cost of installing and upgrading wired networks… if you have to pull cable every time you need to add new ports, it makes sense build for future needs. But this adds costs, year in and year out. In lean economic times, IT can no longer afford this overbuilt model: it needs to “right-size” the network to drive costs out.What we see in these numbers is that when building out a new network edge, including pulling cables, Wired edges can cost ten times as much per user. For networks that have already been built out, the inherent inefficiencies of ports, wires and switches still results in the wired network edge costing about 5x more than wireless edges, each year, every year.For this 1,000-person organization with 225,000 square feet of office space, a traditional build would have been 4 ports per person, which would require 4,000 cable pulls at a cost of $800,000, and 85 Ethernet switches, costing another half million dollars.If they instead rightsize their network edge, offering a blend of ports and pervasive WLAN, they can cut the number of ports in half, the number of switches in half, and even though they add 62 AP and a couple controllers, their overall build costs are about $550,000 less.Ok, but what if they have already built their network, and all those cables are a sunk cost. Does migrating to a rightsized network edge make sense if your network is already built?Yes. That’s because the annual operating costs of wired ports can be as much as or more than the purchase cost. Maintenance fees on typical enterprise Ethernet switches are 15% of list price, which is often between 10 and 11 thousand dollars, so $1600/year times 85 switches is about $130K.Adds moves and changes are more cumbersome with static ports, because you have activate, deactivate and trouble shoot ports. For a typical organization where each employee does an add/move/change at least once a year, this would be about $140K each year with wired ports. Then we have a category with 2 names, “Depreciation” or “Refresh.” If you are on a 5 year closet refresh cycle, then that means that each year you depreciate 20% of the cost of that closet gear. For a CFO or CIO that depreciation is actually a line in your budget. If you are a network engineer, you know that on average you’ll have to get enough budget to replace about 20% of the closet gear each year. For this 1,000-person organization that’s about $107K each and every year. Power and cooling for switches is another $24K. Add it all up, and just rolling out of bed, you are paying $407K per year, or about $400/employee just to keep your wired access layer running. Ok, so what if you rightsized your network edge? We’re not talking about going all wireless, just moving the users that it makes sense to move to wireless for primary data access. Typically this is most of your laptop users. Your maintenance fees would drop almost in half. Moves/adds/changes get much easier. You have less hardware so you have less cost for depreciation or refresh. An AP uses about 1/20th the power of a switch. What you find is that you cut your ongoing edge costs by 40%, or about $145,000/year, every year. Did you notice that the $145K in annual network rightsizing savings is less than the $85K in WLAN build costs?
  • KEY MESSAGE: WIRELESS IS INHERENTLY A MUCH LOWER-COST ALTERNATIVE TO WIRED NETWORK ACCESS. SHIFTING A USER FROM A WIRED PORT TO A WIRELESS NETWORK SAVES MONEY.So how does this work in the real world?One of Aruba’s customers, The California State University system of 23 college campuses with 450,000 students and more than 40,000 teachers and staff, was coming up on their 4-year closet refresh. They were deciding what equipment would be the new standard.To get usage data, they used a network monitoring too called “StatSeeker” which gathered data from all of their switches. They found that 40% of the switches had zero bandwidth usage over a period of several months. Zero bandwidth usage. So they asked themselves, “Why replace port capacity that nobody is using?”Instead, they rightsized their network edge. They shrank 90% of their wiring closets. Where they had 2 chassis, sometimes they got it down to one chassis and reclaimed the other. Where they had one chassis, sometimes they got it down to a stack of pizza boxes. In fact, they saved so much money that they were able to buy more than 2,000 802.11n AP with the savings.And, this is the best part, the way they knew that they had done the right thing for their users was that bandwidth usage went up.This was counterintuitive, but they removed ports that were redundant, or in the wrong place, or broken, and replaced them with AP that were accessible to anyone within the radius of the AP, and much more convenient, so of course overall bandwidth usage went up.
  • KEY MESSAGE: WIRELESS IS INHERENTLY A MUCH LOWER-COST ALTERNATIVE TO WIRED NETWORK ACCESS. SHIFTING A USER FROM A WIRED PORT TO A WIRELESS NETWORK SAVES MONEY.Another interesting case study comes from Aruba’s customer KPMG, which is a global management consulting firm. They were moving 2,800 employees from different buildings into a new 700,000 square foot (65,000 square meter) office building near Amsterdam. With their old standard, they would have pulled and patched 12,000 cables at a cost of about $2.4 million. This would have required more than 50 chassis and 260 blades at a cost of another $3 million, for a total of $5.4 million. Instead, they rightsized their network edge. They used half the number of cables, chassis and blades. They purchased several hundred 11n AP to provide dense and pervasive WLAN, but the overall savings was more than $2 million on day-1.The best part was that by reducing the average number of ports per user from 4.4 to 2.1, they cut an estimated 3/4th of a million dollars from their recurring operating costs.
  • KEY MESSAGE: 802.11N IS A KEY ENABLING TECHNOLOGY THAT MAKES IT POSSIBLE TO SHIFT USERS FROM THE WIRED NETWORK TO WIRELES… BUT THE .11N STANDARD ALONE IS NOT ENOUGH TO MAKE RIGHT-SIZING WORK.Many IT professionals would be asking themselves at this time, “Can wireless replace the wired edge today?”The majority of analysts say, “Yes.”802.11n offers approximately 150 Mbps of shared throughput, which Burton Group says “for many organizations will be good enough.”While WLAN has slightly more latency than wires, it is imperceptible to human beings, and analysts conclude it is “…more than good enough for most latency-sensitive applications.”11n includes Multi-In, Multi-Out, better signal processing, and generally better signal to noise ratio, which analysts conclude even for voice applications is good enough.11n AP enhancements also make legacy 11abg devices perform better, closer to their actual potential. Additionally, more than 10 million 11n chipsets have already shipped, and most laptops purchased in 2009 will be 11n capable.Clearly, 11n is a key enabling technology, that analyst Craig Mathias of far point group says can offer a “…wire-like performance.” under good conditions. We don’t always have ideal conditions, however.802.11n alone is not enough to achieve robust network connectivity in evolving or crowded environments.
  • KEY MESSAGE: ONLY ARUBA CAN MAKE RIGHT-SIZING A REALITY BECAUSE ONLY ARUBA HAS THE TECHNOLOGY TO MAKE AN ‘ALL-WIRELESS’ NETWORK SECURE, RELIABLE, MANAGEABLE, AND SCALABLE.For right-sizing to be real, something you can count on for heavy use by a large portion of your users, you need to be able to deliver these 4 things... And only Aruba can do it.Your WLAN has to be reliable. It’s obvious, but early wireless was fickle. Aruba changed all that, and is now on the second generation of our Adaptive Radio Management, which analyzes the airspace and uses advanced algorithms to automatically adjust AP power, channel, and steer clients to the best AP for optimum reliability and performance even in the most crowded and challenging environments.Your enterprise WLAN has to be secure. This is obvious, but only Aruba offers native Identity-based security with a stateful firewall enforcing policy based on the rights of the user or device. Only Aruba offers endpoint-to-core encryption for absolutely secure session. This security, which complies with military, medical and financial regulations out of the box, is more secure than most wired networks.To efficiently manage your rightsized network edge, it is important to have centralized visibility and control. Only Aruba offers best-in-class centralized support for all WLAN users in all locations. In fact, Aruba’s centralized management is so good, many of the world’s largest Cisco WLAN’s use Aruba’s Airwave management console to make it work better. Finally, to scale the benefits of network edge rightsizing, your WLAN has to be…scalable. Aruba has the highest performance WLAN controllers, with the most capabilities, and yet in a far more cost-effective platform.
  • KEY MESSAGE:CLIENTS AND APPLICATIONS ARE GETTING MORE COMPLEX AND DEMANDING… MEETING TODAY’S PERFORMANCE REQUIREMENTS NECESSITATES COMPLETE CONTROL OVER THE INFRASTRUCTURE – AND ONL Y ARUBA CAN PROVIDE THISAruba pioneered Adaptive Radio Management (ARM), and with the release of Aruba ARM 2.0, offers even more exclusive automated optimization.Aruba ARM 2.0 is entirely within the 802.11 standards, so it works with the widest range of devices, the widest range of applications, mulitple operating systems, and extremely high density user environments. ARM 2.0 allows every client to operate at its highest throughput, resulting in more efficient use of the spectrum, 20% better fairness, 40% less interference and more than 30% more overall throughput. Aruba ARM 2.0 is a crucial innovation to making WLAN a true wire replacement.
  • KEY MESSAGE:MANAGEMENT IS KEY TO DELIVERING COST REDUCTION VIA NETWORK RIGHTSIZING – WITHOUT IT, OPERATIONS COSTS WOULD SKYROCKET AS THE NUMBER OF WIRELESS USERS INCREASES. AIRWAVE ALLOWS THE IT STAFF TO EFFICIENTLY MANAGE EVEN THE LARGEST WIRELESS NETWORKS.To efficiently manage your rightsized network edge, it is important to have centralized visibility and control. Only Aruba offers best-in-class centralized support for all WLAN users in all locations. Aruba provides real-time heat maps, remote packet capture, and full integration with help desk systems. Aruba’s Airwave Management console can track years of reports, specialized to document compliance. In fact, Aruba’s multi-vendor centralized WLAN management is so good, many of the world’s largest Cisco WLAN’s use Aruba’s Airwave management console to make it work better. Aruba can help you get additional value from your legacy WLAN by managing old and new equipment via the same high-powered console.
  • KEY MESSAGE:ARUBA PLUG-N-PLAY REMOTE ACCESS POINTS DRAMATICALLY REDUCE COSTS BY SECURELY AND EASILY EXTENDING THE NETWORK EDGE TO ANY LOCATION.Aruba can extend your LAN out to remote sites. With Aruba’s Remote Access Solution technology, you can plug an Aruba Access Point into an Internet connection anywhere in the world and it will create a secure tunnel back to your data center. For a user accessing that AP, it is as though they are on the corporate LAN, able to run any applications. This allows you to easily and cost-effectively deliver a virtual branch office, minus the local servers and IT headcount, anywhere in the world.This reduces upfront capital expenses, monthly networking line fees, and ongoing IT support costs. This can make telecommuting and distributed teams much more effective.
  • It’s really very simple. The day of the Switch…is over. WLAN AP are less costly, more flexible, support higher value mobile applications, and cost less to own.Consequently, Yankee Group in their 2009 predictions, expects that this will be the first year ever that ethernet switch sales will go down, and recommends IT professionals use this upgrade cycle to make Wireless networks the primary means of network access. Help your users, help your budget, help your organization be more productive with the rightsized network edge.
