In my last post, I talked about how we all – in our personal, and for those of us in technology, our professional lives – are trying to simplify and do more with less. This all sounds good in a data center unless it increases risk and/or lessens our actual visibility for control over our data and applications. We all get great offers and PowerPoint slides about how vendors A, B and C can easily simplify our data center and consolidate tier 1 and tier 2 applications down to virtualized servers.... but often, I am left wondering several things: Have these vendors done this before? Will they be around to support it? Will it really be cheaper when I calculate the OpEx required to manage all those virtual server sessions I can no longer see and touch?

 

Enter the HP StorageWorks P2000 G3 virtualization bundle!

 

Today Brocade and HP launched a solution that has been specifically developed and designed to help customers migrate their real tier 1 and tier 2 applications to the cost-optimized world of server virtualization. HP is utilizing specific technologies from Brocade (adaptive networking and server application optimization) to make sure, as you move those applications to a virtualized environment, you can truly identify, monitor and assign QoS to each virtual machine (VM) and application all the way through the network. By providing true application and VM-aware networking, Brocade and HP together have addressed the top two concerns of providing performance under load and manageability in deploying server virtualization.

 

In addition to developing a turnkey solution with application visibility and control to allow top-tier applications to enjoy the benefits of the virtualized world, Brocade and HP are providing the HP StorageWorks P2000 G3 virtualization bundle to the market with a starting list price of $25,000, with significant savings to the aggregated component pieces.

 

Now, you just may be wondering, have these two partners ever done this before? In addition to pioneering the SAN industry, HP and Brocade have led -- by a wide margin -- true enterprise SAN development and enterprise implementations. Recently, HP has crossed the seven million Brocade SAN switch and director port milestone, and is rapidly well on the way to eight million. If that’s not experience, I don't know what is.

 

Happy virtualizing!

In today’s environment of natural disasters, power outages, virus outbreaks and other IT interruptions that can bring business to a halt, it’s crucial for companies to have reliable IT solutions that give them always-on access to critical enterprise data. Some companies have learned the hard way – through life experience – that application downtime and data loss can be extremely costly, even to the point of decimating businesses altogether.

 

In addition, we are seeing companies depend more heavily on data centers that are remote and dispersed. It wasn’t too long ago that doing any type of data replication or migration “over distance” would have been an extremely novel, cutting-edge (and even scary) concept. Today, companies routinely manage systems across the world to gain efficiencies and scale for competitive advantages.

 

Given the importance of these trends, we are excited today to announce the Hyper-V Live Migration over Distance solution, which has been jointly architected and tested with our partners Hitachi Data Systems and Microsoft. Live Migration over Distance builds on the Hitachi Storage Cluster for Microsoft Hyper-V to take virtual machine (VM) mobility to the next level. This solution provides technology and integration that help organizations to proactively migrate Hyper-V VMs and data across distance, without worrying about user interruption or data loss. This can provide reliable, high performance, predictable VM-mobility for disaster recovery, application workload balancing, routine maintenance, and decommissioning or integration of new data centers.

 

Brocade provides the virtualization-aware network infrastructure (Brocade Fibre Channel SAN and IP) – and the end-to-end network management capabilities that optimize the environment. There are three advantages to Brocade’s technology for this solution:

  1. The network reliability for this solution should not be underestimated. Brocade’s nonstop networking gives companies a reliable networking solution – without dragging down server performance.
  2. The virtualization-aware element of Brocade’s network means that the network knows when a VM is migrated across servers, and takes appropriate actions for the VM’s network profiles to follow the VM.
  3. Integrated with the toolset provided by Microsoft, Brocade’s management capabilities enable performance monitoring of virtualized workloads and policy-based migration of virtual machines for workload optimization.

 

Our partners are also supplying key aspects of this solution. Hitachi is providing the storage foundation as well as the storage clustering and synchronous replication software, which enables the movement of the VMs and associated data across distance. And of course, Microsoft’s piece is the Hyper-V virtualized environment, live migration functionality and management.

 

We think the Microsoft Tech∙Ed 2010 show, taking place this week in New Orleans, is an excellent venue to announce Hyper-V Live Migration over Distance. Brocade is a silver sponsor at the show. If you’re attending, come by and visit us at Booth #501. Also, Brocade is a finalist in the Best of TechEd Awards, so be sure to vote for the Brocade DCX-4S Backbone in the Hardware and Storage category for the Attendees’ Pick Award!

Tell me I am not alone on this… As my kids grow, my job demands increase, my body ages and I have to get a lot more accomplished in my personal life in the same fixed 7-day week…very real images enter my brain about all the data center managers I have met around the globe. Corporations are demanding more and more from their limited and often flat to down IT budgets and resources … just as life demands more from all of us as time moves forward in the same, fixed amount of time…and, at least in my case, with a less current-generation chassis!

 

Many of these factors are why you have seen Brocade and all of our global OEM partners continue to engage to develop more tightly integrated solutions that can be designed, procured, implemented and supported by single organizations. A recent example of this is Brocade’s work with IBM’s System x server organization. The System x group is “OEM’ing” two key platforms that are specifically designed for integration with server environments: the FCX 648 and the TurboIron 24X. With IBM selling 100’s of thousands of servers into data centers every year, their customers are asking for more tightly integrated server and networking solutions to reduce cost, improve service and manage risk while also laying the foundation for future demands on their IT. With Brocade’s deep data center networking experience, we have specifically designed our technology to not only meet the demands of today and the future, but also to be tightly integrated with broader solution providers’ overall solutions such as those from IBM.

 

Another great step toward simplification in the data center, while reducing costs and preparing for the future with latest generation technology. Does anybody know where I can get a new to slightly used, well-integrated chassis to simplify and streamline the operations in my personal life?

OK, so typical office banter after returning from travel:


“How was the show?”


“Oh, you know, same as usual, glad I went…”


Well not this year! At least not for me nor for those who met with Brocade during EMC World. In fact, there was such a difference in Brocade’s overall experience at the event that this year and last might be compared to listening to an AC/DC concert, with last year being through my stereo system with pretty good subwoofers and this year a front row seat with all the energy and ear-shattering you would expect. So it was with EMC World 2010.


Last year it seemed a lot, if not most of the discussions were focused on VCE, the partnership between EMC, Cisco and VMWare.  This year, the volume was turned way down on that. As you may have seen in the story named “EMC-Brocade 10 Gigabit Ethernet deal raises questions for Cisco,” EMC announced it would be selling Brocade IP/Ethernet solutions. This not only obviously benefits Brocade, but gives customers the choice they continue to demand, especially in a time when vertically integrated solutions such as Cisco’s UCS are at that point in the hype cycle where people are still saying, “what?”


In fact, if called upon to name a theme for the discussions I had (from the roughly 90 meetings that six of us from Brocade had in three days), it would definitely be “Choice.” That’s what people want, and why they stay with Brocade.


Beyond that even, the event was a blast! I can’t say it would have been fun for the whole family, necessarily, but for guys like me who have clocked quite a few miles, this event seemed to rise above most others. In addition to the fantastic discussions we had with customers and partners, we tacked on a night party at the House of Blues

Jointly drove a very successful Be Next campaign with EMC

And I even made it to a Red Sox game!

By the way, people who enjoy American baseball but question the entertainment value of cricket based on the game’s length and complexity must enjoy watching paint dry and grass grow. No offense, of course, as I know there’s two sides to every story. However, I do understand the value of enjoying hot dogs and a cold one right at your seat vs. breaking for tea near the cricket field – so I guess everything evens out.

In March, a nor'easter came roaring up the U.S. East Coast knocking down trees, taking out power and forcing many residents in NY, NJ and CT to boil their drinking water. When the power went out in my home around six pm, the backup power unit kicked in to keep the cable modem alive, the laptops shifted from AC to internal batteries and the Internet died.


With all the precautions taken, our desktops and laptops were stranded. No Web sites, no IP phones, no streaming movies. Virtual bricks so to speak. However, a light was shining as the sun set. That light was coming from my smartphone. While restaurants and coffee bars in my town were closing, the applications and the signal bars on my phone were still open for business. The “G” in 3G was saying “GO” not “GONE.”


According to Infonetics Research, the number of mobile broadband subscribers surpassed DSL subscribers for the first time in 2009, and is forecast to grow to 1.5 billion worldwide in 2014. This shouldn’t be a surprise. Mobile broadband is primarily a “personal” connection while wire-line broadband is a “premises” connection.


In my home, I have computers, gaming consoles and media players sharing a cable modem. In the same home there are three 3G phones. My home has one broadband connection provided by the cable company, and each 3G phone has one provided by the mobile provider. That 3 (mobile) to 1 (home) ratio is not uncommon—and in many homes it’s even higher.


The move to mobile broadband is being encouraged further by the ability to purchase portable hotspots. These handheld devices (and soon phones) combine 3G and 4G access with Wi-Fi, enabling up to five devices to share a mobile broadband connection.


An FCC broadband survey conducted in late 2009 reveals that 15 percent of all Americans use wireless broadband with a computer today, and that number is also expected to grow rapidly. The move towards tablet computers with mobile broadband capabilities will further increase the number of mobile connections and demand for richer content.


In developing nations, wireless is projected to be the dominate Internet connection. For example, as Haiti rebuilds from a devastating earthquake, the country is considering rebuilding its broadband infrastructure on the back of mobile technology.


By some estimates, each smartphone consumes as much data as 30 traditional cellphones. And when you add mobile broadband-connected laptops, netbooks and tablets, that number can jump to as high as 450. The anytime, anywhere nature of mobile access, combined with the rollout of higher-performing WiMAX and LTE networks, will continue to reshape the application and content expectations of consumers and businesses alike.


In the end, it’s all about managing more data. Mobile technology provides another Internet access point, which in turn increases network connections, which drives up the number of users, who demand sophisticated applications and richer content, which requires more bandwidth, which increases demand on IT resources, which forces IT infrastructure to scale and adjust or collapse. In a world where the user is always on the “GO,” services can never be “GONE.”


At Brocade, we are keenly aware of this rapidly emerging phenomenon. Our next-generation technology combines years of experience in carrier networking and application delivery as well as a tradition of bet-your-business data center networking. This is a wining trifecta in the race to enable virtual infrastructure. More importantly, we understand why a single-transport infrastructure with rich application-aware services will become integral to managing client connections, applications, workload, server mobility and storage. The virtual infrastructure will derive its utility from the agile network.


Less will become more as people drop the wire and go wireless with mobile broadband. As a result, more data centers will move from yesterday’s infrastructure architectures and into tomorrow’s cloud architectures. So a nor’easter of sorts is beginning to blow through data centers around the world. This storm is not originating from the Atlantic but rather the coast of the mobile network. And these counter-clockwise winds are driving user demand into data centers in ways we’ve never seen before.


All of which makes you wonder: Is your infrastructure ready for the impending storm?

Dealing with a critical situation, or “crit sit” is a nightmare for customers and IT vendors alike. A failed piece of equipment or software application, whether for technical or human reasons, generates a considerable amount of disruption, discord and finger pointing. Fortunately, an increasing number of our customers are either replacing their “legacy” (read: other vendor's) networks with our gear or expanding their Brocade deployments because crit sits are a rarity at Brocade.

My good friends in Brocade engineering have done wonders over the years by designing quality and reliability into every product we sell.  In recent times, as networks have grown to a size and level of complexity we would have considered unthinkable a few years ago, the boffins in R&D have surpassed themselves by developing an array of “RAS” capabilities that are unmatched in the industry. RAS stands for Reliability, Availability and Serviceability. It's a term used to describe the way companies diagnose, troubleshoot and fix problems when they occur in their products - or preferably before they occur. Brocade RAS shows up in the form of software tools that enable you to identify -- with pinpoint accuracy -- the root cause of problems affecting the performance of the network.  The level of sophistication designed into these tools is the IT equivalent of being able to locate the group of microscopic human cells causing that nagging back pain you've had for the past few days, being able to zap the cells, and then getting back to normal....get it, "back" to normal?  OK – so I'm corny and the example is a bit of stretch – but you understand the analogy.

Being a networking company, Brocade and our gear touch almost every other element of IT at a customer site.  We're in the data path of each piece of digital information traversing the network, shaking hands with almost every application, PC, printer, server, storage device, gateway and firewall out there. You name it, we interface with it. As a result it is not uncommon for the network to be found “guilty until proven innocent” when IT systems break or even just slow down.  Hence the need for networking companies like us to have super smart tools buried deep in the operating system layer of our products - tools that can quickly and efficiently spot the offending device, application or cable, deal with it (a.k.a. shut it down, open up an alternative path, or fix it) and get everything up and running as quickly as possible. When that process fails, crit sits occur.

Crit sits are complex and often emotionally charged situations. While usually everyone is focused on the right thing i.e. helping each other to fix the problem, sometimes things can become fraught as patience wears thin, the clock is ticking and the CEO can't get access to email. I am proud to say that Brocade has developed not only the tools but the right attitude in dealing with these situations. By focusing on the best outcome for the customer and using the tools we have developed to spot and fix business-affecting issues, we are able to resuscitate the heart and lungs of the company - its network. From a sales perspective, there’s no better claim to make.

As expected, the Federal Communications Commission (FCC) this week submitted its proposal to Congress outlining a plan to increase the quality and the quantity of broadband connections here in the United States. By doing so, the United States is following on the heels of countries such as Singapore and Australia who have already adopted national broadband plans to increase broadband usage in their countries.


As a CEO of a networking company, my position on the broadband plan is not as clear as it might seem. There is no doubt that I would view any plan that increases the use of networking technologies and possibly accelerates the upgrade cycles of networking hardware and software as a good thing. However, some of my best customers, particularly those in the service provider industry, may have some serious reservations and concerns about further regulation of their business by the federal government. I must weigh both views in formulating my own opinions.


But, putting aside commercial interests, I believe that this is the time for the private sector to partner with the public sector to help not only create a national plan for broadband but to put the plan into motion. In addition, I believe there are at least two other areas that the private and public sectors can partner on (specifically in corporate tax and educations reforms) that will help keep the United States as the world’s leader in innovation, a position that is arguably more tenuous than it has been in more than 150 years.


This was the basis of a recent speech I delivered to an audience full of fellow CEOs and captains-of-industry. In it, I outlined a three-step proposal that the US should adopt to keep our competitive edge especially compared to countries in emerging regions that are less burdened with legacy technology infrastructures and regulatory structures than we are. Specifically, I called for action on these three areas:


  • One, work with the federal government and develop a sensible national broadband plan.
  • Two, introduce comprehensive corporate tax reforms that will result in more US exports of technology and encourage more R&D investments.
  • Three, increase our investment in educating our students in math and sciences through whatever means including overhauling our arcane public education system.


I have posted a complete copy of the presentation with notes below. You can download the full file by clicking on the icon. I would greatly appreciate to hear back from you with your thoughts – good, bad or indifferent – on my proposal. I hope to inspire a healthy dialogue on the three areas of action and to foster collaboration among businesses and the federal government to help get the U.S. recapture its history of innovation and economic leadership.

I wanted to share with you a great example of how we are using new social media tools to help connect joint partner customer communities around hot IT topics. This was the first time Brocade and NetApp had tried such an endeavor and we were both pleased to help close the knowledge gap around an increasingly important topic: data encryption.

Currently 45 states within the US have enacted consumer privacy laws to protect customers’ Personal Identifiable Information (PII). Some states like Nevada & Massachusetts have gone further to mandate the use of encryption for anyone who “collects data”. In today’s global web-based economy, it is not just financial services and healthcare organizations that collect & save customer PII, so the new mandates are far reaching. The EU also has very strict rules around personal privacy which can be addressed using encryption technologies.

Brocade and NetApp deliver solutions that can be seamlessly deployed into a customer’s data center to encrypt data stored in disk and tape storage systems. NetApp’s LKM key management products coupled with the Brocade encryption products create high performing solutions and I am glad we were able to help demystify some of the finer points for our joint customers.

The event was a great success with 4421 page views across both NetApp & Brocade communities. I am looking forward to more of these types of events where we work together with our ecosystem of partners to help simplify networking-based solutions for customers everywhere.

It’s nine o’clock on a Saturday night and the regular crowd is standing in line at the coffee shop ordering lattes, Frappuccinos and mochas. I’m here, but I’m not supposed to be here. Normally, I’d be on the other side of the country, but my flight was canceled due to inclement weather. Between the heavy rain in the West and the heavy snow in the East, my scheduled flight, well, couldn’t fly.


All this precipitation started me thinking about how we look to the formation of clouds for answers to questions about the weather—and how companies looking to deliver services from the Clouds also ask about Whether.


I started fielding “Whether” questions in the late 1990s. I guess you can say I became something of a Whetherman. Several months before the century gave way to the Y2K issue, I left behind years of technology management on Wall Street and joined a start-up company based in Waltham, Massachusetts. The premise behind StorageNetworks was simple: deliver storage as a service over a “wire.” Our customers would subscribe to capacity that would be delivered (provisioned) within the constraints of an SLA. The model worked and many companies (large and small) leveraged the service to meet the growing data demands of the dot-com era.


StorageNetworks essentially provided a cloud service. We didn’t call it cloud at the time, but that’s what it was. We owned the assets and provisioned parcels of storage to customers who in many cases shared common infrastructure. We provided storage services from public and private data centers. We met with companies ranging in size from dot-com start-ups to established enterprises. There was little doubt we could deliver cloud storage. Actually, the responses mostly ranged from excitement to curiosity. But, in the same way a low cloud ceiling keeps planes on the tarmac, Whether kept many customers from taking off into early cloud storage.


The customers always wondered Whether they should do it. Whether services would be responsive to their business needs. Whether the right levels of data security would be applied. Whether the infrastructure would be available 24×7×365. Whether subscribing to resources would keep them competitive. Whether the subscription model would truly reduce costs compared to an ownership model. Whether they were headed toward vendor lock-in. Whether they could trust it.


In the late 1990s the Internet was less than a decade old, cell phones called home instead of calling up home pages, a sales force was something you had (not something you used) and Twitter wasn’t tweeting. A lot has changed since then. The pervasiveness of cloud services today for consumers and professionals has reduced the resistance to placing digital assets beyond arm’s length. But the ubiquity of the cloud for end users has only raised more questions about Whether for those providing cloud services.


The bottom line is that end users expect applications to be available, period. No excuses. So providers have a wide range of Whether-related issues to contend with, such as:
• Whether they can handle an unanticipated deluge of requests
• Whether they can mitigate morphing security threats
• Whether they should expand infrastructure to support customer growth

• Whether the infrastructure is reliable enough to meet availability SLAs


For service providers this means building physical cloud infrastructures with the most reliable, efficient and high-performance technology.


When I was responsible for early public and private storage clouds, we leveraged Brocade technology to meet many of these Whether challenges. Today, the next generation of Brocade data center technologies is simplifying the boundaries between SAN, LAN and application delivery. These products are designed to meet the growing demands on physical infrastructure, virtualized infrastructure and applications. Our goal at Brocade is to help our customers think less about the Whether by providing them with the networking reliability and scalability to meet their business demands.


Well, it’s cloudy weather today in the Bay Area but, as I sit here in Starbucks with Wi-Fi and 3G, I have no doubt Whether it’s cloudy everywhere. Ah, you gotta love a hot latte and the Netflix instant play queue to make being stranded feel almost like home.

According to IT analyst firm, Forrester Research, approximately 40 percent of businesses will significantly increase their spending on new IT security technologies in 2010.

What’s driving the need for network security into 2010 and beyond? I see three things:

  1. The growing global nature of business including malicious and competitive forces as well as increasingly mobile employee workforces, all of which pose security threats.
  2. Increase in data security regulations and compliance requirements.
  3. Customers’ desire for best-of-breed solutions that are seamlessly integrated, so that their data center is not the point of integration.


Since Brocade is recognized as a leader in end-to-end networking, naturally many of our customers approach us for network-based security solutions. However, we’ve made a strategic decision to focus on providing the best networking solutions on the market and rely on a strong ecosystem of partners to provide best-of-breed point products and solutions.

To provide our customers a total solution for network security, we recently announced a partnership with McAfee, the industry’s leader in enterprise security solutions. This is more than just a marketing announcement, Brocade and McAfee evaluated shared risk, shared investment and division of labor to encompass features that customers need. From this partnership, joint customers will be able to implement today:

Comprehensive networking + security solution

  • Endpoint security from core to edge


Reduced business risk and improved compliance

  • Maintain compliance with federal, state and industry security regulations


Validated solutions

  • Interoperable and integrated solutions
  • Both companies are committed to open architectures and standards giving the customer the flexibility and choice they desire


In our next phase we will continue to work with McAfee to deliver a set of jointly-designed solutions developed specifically to address the network security needs of enterprise customers. The first stage will involve extending the network management integration to further utilize metrics and security intelligence information.

Our vision at Brocade is to provide the industry’s leading networks across the data center, campus and service provider customer segments. As our customers’ environments become more demanding, we will continue to leverage our unique partner model to provide best-of-breed solutions that are tested and qualified to drive out their operational costs. While the best day for many partnerships is the day of the press release, we’re already seeing significant customer demand and value from this new relationship with McAfee.

In my January blog I provided a high-level overview of the technology at Brocade’s new state-of-the-art San Jose campus. Now, I’d like to focus on a specific area of that infrastructure, one that’s critical to Brocade and to its customers: the network.


We began mapping our requirements about a year and a half ago. The goal was to design a high-speed, secure, scalable, and reliable IP network foundation – one that would deliver the right mix of functionality, performance, scalability, security, and cost savings. Wherever possible, we wanted to leverage our own capabilities and products.

 

In fact, the SAN and IP networks at the new campus will rely on Brocade products exclusively for the fast and reliable connectivity we need to serve the ever-growing demands of business applications. To limit downtime during data migration, Brocade will use its SAN/Fibre Channel products to complete an 8 Gbps Fibre Channel connection between the SAN infrastructures serving the current buildings and the new campus. Brocade NetIron XMR Series routers will link the existing and new IP networks at 20 Gbps of bandwidth with virtually no latency.

Image-1---NetIron-XMR-4000_BlogPost.jpg

The network transport connecting the Brocade campus and vendor-neutral co-location facilities will travel over a dense Wavelength Division-Multiplexing (WDM) network with optical protection, for uninterrupted, high-bandwidth connectivity to the outside world. To provide best-in-class content delivery, we’ll use the Brocade ServerIron ADX platform.

Image-2---ServerIron-ADX-4000_BlogPost.jpg

WAN connectivity between Brocade and partner networks will leverage inexpensive Ethernet and allow us to connect directly to service providers and business partners with cost-effective, scalable bandwidth via co-location facilities. This gives us the flexibility to engage as needed, match capacity to demand, and pay as we go.

 

The network core and data center at the new campus will use Brocade NetIron MLX technology. Because our technology eliminates the need for the aggregation layer in a traditional network configuration, we can connect the network edge directly to the core. This will greatly reduce capital outlay and simplify operations. It also lessens requirements for space, power, and cooling for lower total cost of ownership.

NetIron-MLX-32_BlogPost.jpg

We’ll further reduce our space, power, and cooling requirements in our wiring closets by installing Brocade FastIron CX access switches at the network edge. Essentially, we’re looking at every opportunity to do more at a lower overall cost, and to do it better.

FastIron_FCX648S-HPOE_BlogPost1.jpg

Finally, we’re leveraging our OEM relationship with Motorola to build a next-generation Wireless LAN (WLAN) at the campus. Basically, the entire facility will be a Wi-Fi hotspot, which will help maximize productivity by allowing employees to seamlessly connect to business applications, regardless of their location on campus.


With just 10 weeks remaining until move-ins start, there’s still a lot to do. When it’s finished, the new campus will be served by a world-class converged IPv6-ready network offering a secure, scalable, and robust voice and data platform for assured rich multimedia content delivery. The network will serve VoIP, wireless, video, and Web services, and support future applications such as Fixed Mobile Convergence and Unified Communications (UC). We’re excited about our momentum, and I’m pleased to report that we’re on schedule.

This is the first in a series of blogs I am writing to cover technical topics as the industry gears up to build next-generation data center architectures. These blogs are intended to provide a basic overview of the innovations that Brocade and the industry at large are developing.

In today's introductory blog, we take a step back with an overview of a technology that we are very familiar with in the Ethernet world—Spanning Tree Protocol (STP). If you know Ethernet networking, you know that STP has been the primary protocol in Layer 2 LANs since the very beginnings of Ethernet. Its primary goal is to create a loop-free topology that provides a single active path between any two network endpoints, by shutting down all but one path between any two switches. While this approach has served the development of Ethernet well, STP does have bandwidth, performance, and, ultimate cost and management limitations in light of the advent of converged data center architectures.

Various networking vendors have developed mostly proprietary enhancements to STP to address these shortcomings, but these are all stopgap measures to mask network-level inefficiencies. As we move forward to the virtual data center and cloud computing architectures, these vendor-specific solutions will take too much time to reconverge when a link or switch goes down or an application migrates from one server to another. With STP, data can take a path through several switches because a shorter path is disabled. During the time it takes for links to reconfigure and reconverge, the entire network is unavailable. This is unacceptable for mission-critical applications, hence the move toward "lossless" Ethernet technologies—namely Converged Enhanced Ethernet (CEE) or Data Center Bridging (DCB). (More on this in a later post.)

What is needed is to re-architect the way traffic should flow, so that it makes better use of all the available paths. This requires the building of larger, physical/logical networks (think flatter) to account for applications such as Virtual Machine (VM) mobility across interconnected hosts within a single network. Brocade is working with the Internet Engineering Task Force (IETF) on a standard called Transparent Interconnection of Lots of Links (TRILL), which provides multiple paths via load splitting. TRILL will allow us to reclaim network bandwidth and improve utilization by establishing the shortest path through Layer 2 networks and spreading traffic more evenly. The net effect is that the network can respond faster to failures. By addressing the limitations that STP poses, the data center network will be able to scale to meet the demands of virtualized and cloud computing environments with on-demand Layer 2 network capacity.

In my next blog, I will explore the benefits of flattening your Layer 2 networks.

These days, we hear a lot about cloud computing and how it's a massive shift from the traditional approach to a large-scale Internet-based service delivery environment. I'd like to shed some light on the technical aspects of this new model - hopefully providing some insight into the unique challenges we experience at Hostway.

 

 

From a basic infrastructure standpoint, not much has changed from the days of discrete hosting. The technological challenges in that arena have always been network reliability, power, cooling and scalability. The cloud model actually makes datacenter power delivery easier, as datacenter space experiences less churn while virtualization drives server consolidation. Server consolidation means less cooling is required and although density is higher, so is overall power efficiency.

 

 

The network, however, is radically different. In the datacenter, with multiple customers sharing the same hardware in most cases, a failed Ethernet port no longer means a single customer is offline. More than ever, absolute reliability is crucial. To this end, we now heavily rely on quality, rock-solid network devices and fast-acting, intelligent solutions to fault tolerance such as VSRP and Metro Ring Protocol in place of Spanning Tree.

 

 

Flexibility and scalability are just as important with the "have it your way, when you want it" nature of cloud hosting. Let's say a customer wants a number of instances, combined with a dedicated firewall and access to their portion of a shared iSCSI SAN. Not only must you have the flexibility to create this configuration, but the capacity to deliver it. Port density is very important in this environment.

 

 

Cloud hosting has also forced us to adjust our scope. No longer is a service restricted to a single datacenter or geography. The network must be able to reach further out to the consumer while providing overlay services, similar to CDN. In our case, this meant deploying our own multiservice transit network, capable of bringing our customers' data right to the edge while also bringing our datacenters closer together.

 

 

We chose to build our transit network on MPLS, with both IPv4 and IPv6. Traditionally a heavyweight technology, MPLS implementations are now mature, optimized and provide some very powerful advantages for large networks.

 

 

Our platform of choice is the NetIron XMR, which has density and configurability that allows us to deploy a much simpler POP. Wire-speed routing and switching on ports up to 10 gigabit Ethernet enable us to fend off DDoS attacks and handle unexpected surges in demand with grace. Just a few years ago, the same capability would have required a multitude of vendors and power-hungry devices.

 

 

It's been quite a journey the past few years and we're still evolving, but I'm excited to see where cloud computing takes us, both as an engineer and an Internet user.
