Improve Your Backbone, Improve Your Business

Cisco recently announced the Cisco Catalyst 6840-X backbone switch to address new network backbone needs, especially in space constrained deployments.

According to the Visual Networking Index, Network traffic has grown exponentially over the last several years, and this trend is expected to continue into the foreseeable future. By 2018, there will be over 20 billion networked devices, a 100% increase from 10 billion in 2011. Business IP traffic is expected to reach 13.1 exabytes per month in 2016[1].

While devices grow in number, wireless connectivity speed is increasing. Gigabit wireless (802.11ac) enables a network that is three times faster due to its 1.3 Gbps capacity.  802.11ac Wave 2 more than doubles that.  Thus, the bottleneck is moving “up the network” from wireless AP to the access uplinks. With 1G becoming the standard for access switch ports, access switch uplinks will need to move to ubiquitous 10G and 40G.

To help improve business, networks must be capable of scaling well beyond the needs of today to deal with the traffic of tomorrow while at the same time providing investment protection.  While most Enterprise network engineers agree with this approach, the actual number of enterprises moving in this direction is still relatively small. According to a report published by the Dell’Oro Group, it’s not a technology issue – there are plenty of products on the market to handle 10G – but the economics of the network upgrade remain the key challenges, such as equipment cost, expense of upgrading and future proofing.

Cisco is changing those economics by offering easy, cost effective, network upgrades to support the explosion of mobile devices and video applications. The Cisco Catalyst 6840-X Series Switch is a prime example.

The Catalyst 6840-X is a 2RU fixed backbone switch6840-X with a line rate of 10G downlinks and 10G /40G uplinks for high bandwidth applications and video. The Catalyst 6840-X is cost effective and is also the smallest MPLS aggregator in the Catalyst Family and offers models with 16 to 40 ports. This is the industry’s most feature rich fixed switch with 15 years of Catalyst 6500/6800 innovations and feature depth built into it day one.

Join us on for a free, live 60-minute webcast entitled, “Get More for Less with the New Cisco Catalyst 6840-X Series Switch,” to  learn how this small but mighty fixed backbone switch enables you to accelerate traffic all across your campus with plenty of support for high-bandwidth applications.  The webcast will cover:

Pssst, IT Operations Analytics Is Actually Cool

OK, using data to make decisions to streamline operations is not a new concept, but the resources and types of data that we have at our disposal is unprecedented. Gone are the days when we had to rely on data only available in the data center. There are new exciting ways to sift through terabytes of data to proactively predict problems before they impact service, optimize your IT and application infrastructure and gain an end-end view of operations.

Today there are more and more applications, devices, users, and tasks. They are generating a large amount of structured and unstructured data at the edge of the network. The net result is the old – read 5 years ago — centralized approach is no longer sufficient enough to guarantee true operational efficiency.

Let’s talk about some of the technology break-throughs and solutions that are driving this:

  • On premise Hadoop offerings are replacing high cost Multi Parallel Processing (MPP) Platforms.
  • Customers are now leveraging NoSQL Databases with Hadoop to uncover analytics from live interactive data to create operational analytics platform.
  • Security solutions are now focusing on meeting the challenges presented by the Internet of Things (IoT) that addresses concerns over malicious intruders and malware.
  • Business users and data scientists are now able to easily and iteratively derive insights from the unstructured data.

As I speak to customers daily, I am amazed that how many don’t realize Cisco is leading the operational analytics paradigm shift with its portfolio of hardware, software and services. Cisco’s offerings are augmented by the partnerships with companies like Cloudera, Hortonworks, MapR, Splunk, Platfora, Attunity, Intel and others to deliver integrated solutions facilitating crucial decision-making that can result in operational excellence and rigor.

To address that lack of awareness, on September 9th, we’re hosting a virtual conference on the topic of Operational Analytics together with Intel and some key Big Data and Analytics partners.


When you go to register, you will notice that this conference is one in a series of three conferences. The first focused on data warehouse optimization, which kicked off June 17th. The sessions held at this event are still available for replay, so be sure to take advantage of the recording for some great insights on how to modernize your data centers. And we’ll wrap the series up with a conference on Business Analytics in November, so be sure to let your colleagues know about it.

Hope to see you on September 9th. Follow me on Twitter for real time updates.

Hosting Provider Zitcom Accelerates Time to Market with Cisco ACI

Recently I had an opportunity to sit down with Thomas Raabo, Network Operations Manager of Zitcom, a premier partner-driven hosting company based out of Denmark. Thomas and his team address companies and applications of various sizes, and were one of the early adopters of Cisco’s Application Centric Infrastructure (ACI). At the time of my conversation, they had this architecture in production for almost 10 months.

Thomas’s take on it was quite interesting. When I asked him to compare the before vs. after scenarios with Cisco ACI, he shared some insights –

  • Time to market dropped from hours to minutes (applications, VMs were deployed much faster)
  • Making firmware upgrades (usually a challenge for any NetOps person), became “kid’s play”.
  • Application teams are better integrated with the network team and have access to the Application Policy Infrastructure Controller (APIC) if they want to. This helps reduce silos.
  • Interestingly, programmers without network knowledge are able to program into networks rapidly deploying new services

Every company’s deployment is unique. For hosting companies the very nature of their business makes it very important to focus on agile service delivery at scale. This is what keeps them competitive and where the network, IT and operations teams can deliver true business impact.

An SD-WAN Bill of Rights

In my last blog post, I talked about the business outcomes customers are looking to achieve when evaluating SD-WAN solutions. However, if you are going to invest in an SD-WAN solution, it is also important to think about the trends that might impact your WAN and remote sites in the next few years. Are you prepared for trends like digital disruption or the Internet of Things (IoT), which are transforming businesses and creating new sources of competitive advantage?

Today’s leading businesses are constantly reinventing themselves to disrupt the market, and they are using the latest technology to do so. Businesses that want to accelerate their digital transformation and stay ahead of the competition need a dynamic network that enables constant reinvention, all on demand. Organizations will need fast IT capabilities that accelerate business innovation through IT simplicity and insights.

Traditional WANs have been built for static applications and are managed using multiple management tools that make it difficult for IT teams to reconfigure and troubleshoot the network when responding to business needs. Solutions for moving to hybrid WAN by augmenting your network with lower-cost connectivity like the Internet, or improving application experience and security, are a first step but still tend to be a static solution.

Software-defined WANs (SD-WANs) promise to ease many of these problems by abstracting the applications and services running on the network from the physical infrastructure and letting you load-balance and shift traffic among networks in response to network conditions. But the SD-WAN landscape is changing rapidly, and not every solution will meet your most critical needs. For example, as security is pushed to the edge of the network, how do you ensure you have the visibility into all of your data without impacting application performance? As more devices and things are connected to your branch do you store the data generated by these devices locally or do you send it over the WAN to your data center for analysis? Are you taking advantage of virtualization to consolidate your branch infrastructure?

Consider this ten-part “WAN Bill of Rights” a guide to evaluating your overall strategy and deciding which SD-WAN solutions will improve your digital business transformation and help you win against the competition.

  1. The Right to Monitor and Tune Application Performance. Getting the best user experience from your applications requires that you know what is on your WAN. Look for solutions that can identify applications passing over your WAN and allow you to prioritize your most mission-critical data and then optimize to save bandwidth.
  1. The Right to Never Visit a Branch Again. No network manager should have to waste countless hours on routine drudgework like managing security and compliance controls, unlocking features, and travelling to remote offices to patch or reconfigure hardware. Look for solutions that let you automate the delivery of business-critical applications from a single location by using templates to deploy new locations quickly and reduce complexity, cost, and the risk of human error.
  1. The Right to Choose Your WAN Connectivity. You have the right to choose the WAN transport that best suits your ever-changing needs for bandwidth, security, and performance. The lower cost of business-class Internet and fourth-generation (4G) LTE can make them compelling alternatives to traditional Multiprotocol Label Switching (MPLS) links. SD-WAN solutions should enable applications to choose the best path based on business policy and the cost and quality of the link for improved reliability and lower management costs.
  1. The Right to Experience Rich Media. An increase in users and devices in the branch office can increase network costs by streaming huge amounts of data over the WAN. Look for SD-WAN solutions that let you cache content locally, especially high-definition video and visual content. You can reduce latency and increase bandwidth savings when you combine caching with other features, such as policy-based configuration, automated prioritization of bandwidth, and the ability to reroute traffic across your network.
  1. The Right to Secure Your Applications and Infrastructure. You have a right to the same security on public Internet and 4G LTE connections as on your private WAN through a consistent, layered security approach at all points of the network infrastructure. Look for SD-WAN solutions that provide policy-based security using advanced threat defense such as VPN, firewall, intrusion detection, network segmentation, and strong cryptography.
  1. The Right to Use Third Party Applications and Services. No one vendor can provide all the applications, features, and services you need to make the most of your software-defined network. Rather than being limited to what a single vendor offers, look for solutions whose open application programming interfaces (APIs) allow IT and technology partners to develop applications that improve how you operate, manage, enhance, and secure your SD-WAN infrastructure.
  1. The Right to Embrace the Internet of Things. Getting maximum benefit from the IoT requires analyzing and acting on the data gathered from IoT devices at the edge of the network. To support IoT applications that require real-time insight into the network, look for SD-WAN solutions that support automated traffic management and cost-effective servers and network devices at branch offices and remote locations.
  1. The Right to a Scalable Architecture. You have the right to automated and efficient provisioning of business applications across your network using centralized policies for application performance, security, and monitoring. Take advantage of SD-WAN solutions built on a common, open architecture that can scale across your branch office, data center, cloud, and campus.
  1. The Right to Flexible Deployment Models. Across the IT industry, cloud-based delivery of IT infrastructure, development platforms, and applications has reduced costs and made it easier for businesses to meet changing priorities. Look for SD-WAN solutions that give you the freedom to be deployed on your premises or consumed as a service from your managed service provider. This “as-a-service” model not only frees your staff for more strategic work, it also helps you scale your WAN as your business grows.
  1. The Right to a Return on Your Investment. The technology and business worlds are changing far too quickly and your IT budget is under too much pressure to do a complete equipment upgrade of your network infrastructure whenever you need more performance or security. Look for SD-WAN solutions that combine flexible consumption models with physical and virtual form factors and the ability to port software across platforms. This model gives you the freedom to purchase only the software you need when you need it, and to protect your software investment as your hardware infrastructure changes.

Breaking the link between network software and network hardware opens new opportunities for agility, flexibility, cost-saving and business effectiveness. But remember your essential rights as a customer to make the most of this emerging technology frontier.

5 Top Challenges of SAN Design: View from our SAN Design Experts – Part 2

Last week, here, I started my 2 part blog on some of the top SAN design and deployment challenges we see.  As I mentioned, I put this together with help from my SAN expert colleagues, Barbara Ledda and Wolfgang Lang.  We are all part of the Cisco Services professional services team, where we experience first-hand the challenges of adopting new technologies including SAN.

Last week, we discussed the following challenges:

#1 Don’t assume that your server multi-pathing software is installed or working, or even licensed, or installed but never used/tested by your server team!

#2 Tendency to significantly over-estimate utilization on the SAN network. 

Lets’ now discuss our challenges #3 – #5, which will discuss interoperability, expertise and architectural details respectively.  Architectural details as it turns out is a key concern of some of you reading Part 1 of this blog – a few questions came in and you can view the discussion here (and thanks to my colleagues Venkat Kirishnamurthyi and Jing Luo for contributing to this discussion). With this in mind, you may find the Cisco MDS architecture discussion video here also useful.

#3 Interoperability doesn’t really exist!

OK, if you are working in a multi-vendor SAN environment, you probably know this already.  Networks rely on standards that multiple vendors adhere to.  Customers also demand innovation in areas that the standard either doesn’t address or hasn’t yet caught up with.  This is the “catch 22” of advanced protocol design.

Some vendors – we won’t name them – have rejected interoperability modes of operation, in favour of adding innovative yet proprietary features.  While we in Cisco have added such features, we always try to design with the “minimum common denominator” in mind i.e. we have retained inter-operability support.  In this way, you can still opt for inter-operability across vendors (albeit at the expense of losing some advanced Cisco-only features, but at least with Cisco, you always have the option to interoperate).

Lesson #3: Question your SAN vendors aggressively on their support for inter-operability.  Or choose Cisco – where you have a choice of inter-operability or advanced feature support!


#4 Lack of Fibre Channel protocol knowledge in IT departments

Love your SAN engineer!

Love your SAN engineer!

Unfortunately, over the past 5-10 years, IT and in particular SAN design and operations teams, have been squeezed as IT budgets have been reduced.  Consequently, our consultants in the field have noticed a significant decline in broad availability of fibre-channel SAN design experts across our customer base.  This has proven a challenge to more than a few companies who have decided to extend or modernize their SAN.

Lesson #4 then is to:


#5 Understand your hardware capabilities really well

Lesson #5 is to ensure that you and/or your design team understand in detail the limitations of your SAN hardware.  Here are some examples of the issues that can occur if you don’t.

As I’ve discussed above, designing multiple redundant traffic paths is a key pillar of best practice SAN design.  Therefore you must consider what will happen if, for example, a SAN line card fails, bringing a redundant path into live network operation.  Will that second line card (and associated switch) be able to cope with the traffic demand?  Don’t assume it will, investigate your hardware capabilities in detail.

It’s important to fully analyse and understand the architectural benefits (or otherwise!) of your SAN switches.  Look – in particular – for architectural issues that will cause, for example, performance issues under heavy load.  It’s not uncommon with some vendor’s switches to find over-loaded ASICs causing SAN performance issues.  There is a good discussion in the comments on my Part 1 blog last week – thanks for these questions guys!

Cisco MDS SAN switches have a non-blocking, non-oversubscribed architecture.  Some of our competitors do not!  If you choose a switch architecture that is NOT non-blocking, non-over-subscribed, they you can expect performance issues e.g. significant jitter and latency in your SAN network. You may find that your switch internally runs out of internal buffer space, causing a long delay in sending frames. In practice, such issues are very hard to diagnose.  (For more information, there is a good discussion on YouTube on the Cisco MDS “Crossbar” architecture and its advantages, which you may be interested in).

Wrapping Up

Concluding my discussion of SAN design challenges, I hope you’ve found this useful.  What are your top SAN design challenges?  Do you agree (or disagree) on our choices of key issues above?  What have you experienced? Let me know via the comments box below or contact me on Twitter and we can discuss with our Cisco Services’ SAN design experts!
