By John Chapman, Cisco Fellow, CTO, Cable Access BU
This week, we and 10,000 or so hard-core engineering colleagues within the cable industry descend upon the city once known as the cable capital of the world — Denver, Colorado — and, like it’s been since the earliest days of the Society of Cable Telecommunications Engineers’ annual Cable-Tec Expo, a trending topic, now and forever, is bandwidth.
The reasons why are obvious, but indulge me a brief recap: Consumer usage of broadband grows at an compound annual rate of 50% or more, ever since about 2009, when Netflix began streaming video, in addition to mailing DVDs. Add to that the sheer number of video-capable, IP-connected screens we all use, and the fact that video itself is only scheduled to get bigger (we’re looking at you 4K), and it’s easy to envision why it’s a considerable challenge to keep the cable infrastructure updated, and capable of ever-increasing carrying capacities.
Here in Denver, we are focused on this challenge. Big picture, we are “transforming” cable access from a DOCSIS focus, to integrate DOCSIS with service provider WiFi, PON & FTTx, and MetroE into a single, easily- managed portfolio, which only Cisco can deliver. Doubleclicking on the DOCSIS pillar alone, we are taking the CMTS architecture and redefining it to deliver far more bandwidth, for far less cost. We see two technologies that stand out: Read More »
This week is exciting, had opportunity to sit on round table with Cisco’s largest customers on an open ended architecture discussion and their take on past, present and future. More on that some other time let’s pick up last critical aspect of High Performance Data Center design namely flexibility. Customers need flexibility to adapt to changing requirements over time as well as to support diverse requirements of their users. Flexibility is not just about protocol, although protocol is very important aspect, but it is also about making sure customers have choice to design, grow and adapt their DC according to their needs. As an example if customers want to utilize the time to market advantage and ubiquity of Ethernet they can by adopt FCoE.
Moreover flexibility has to be complemented by seamless integration where customers can not only mix and match the architectures/protocols/speeds but also evolve from one to other over time with minimal disruption and without forklift upgrades. Investment protection of more than a decade on Cisco director switches allows customer to move to higher speeds, or adopt new protocols using the existing chassis and fabric cards. Finally any solution should allow scalability over time with minimal disruptions and common management model. As an example on MDS 9710 or MDS 9706 customers can choose to use 2/4/8 G FC, 4/8/16G FC, 10G FC or 10G FCoE at each hop.
Let’s review each aspect of flexibility at a time.
Cisco SAN product family is designed to support Architecture flexibility. From smallest to the largest customers and everything in-between. Customers can grow from 12 16G ports to 48 ports on a single 9148S. They can grow from 48 16G Line Rate Ports to 192 16G Line Rate with MDS 9710 and upto 384 ports on MDS 9710. Finally having seamless FC and FCoE capability allows customers to use these directors as edge or core switches . With the industry leading scalability numbers, customers can scale up or scale out as per their needs. Two examples show how customers can use Director class switches (9513, 9506, 9710 or 9706) based Architecture for End of Row designs. Similarly customers can orchestrate Top of Rack designs using Nexus fixed family or MDS 9148S.
If they want to continue with FC for foreseeable future or have sizable FC infrastructure that they want to leverage (and have option to go to FCOE) then MDS serves their needs. Similarly they can support edge core designs, and edge core edge designs or even collapsed cores if so desired.
If customers need converged switch then Nexus 2K, 5K and 6K provides the flexibility, ability to collapse two networks, simplify management as shown in the picture below.
Customers can mix and match the FC speeds 2G/4G/8G, 4G/8G/16G on the latest MDS 9148S, and MDS 9700 product family. With all the major optics supported, customers can pick and choose optics for the smallest distance to long distance CWDM and DWDM solutions in addition to SW, LW and ER optics choices. In addition MDS 9700 supports 10GE optics running 10G FC traffic for ease of implementing 10G DWDM solutions based on ubiquitous 10GE circuits.
FC is a dominant protocol with DC but at the same time a lot of customers are adopting FCoE to improve ROI, simplify the network or simply to have higher speeds and agility. Irrespective of the needs and timeline MDS solution allows customer to adopt FCoE today or down the road without forklift upgrades on the existing MDS 9700 platforms while leveraging the existing FC install base.
The diagram above shows how customers can collapse LAN and SAN networks on the edge into one network. The advantage of FEX include reduced TCO, simplified operations (Parent switch provides a single point of management and policy enforcement and Plug-and-play management includes auto-configuration).
Another example to allow non transition less disruptive for customers Cisco has supported the BiDi optics on the Nexus product family. This allows customers to use the the same same OM2, OM3 and OM4 fabrics for 40G FCoE connectivity and still don;t have to rip and replace cabling plant.
For customer who are not ready to converge networks but want to achieve faster time to market, higher performance, Ethernet scale economies can use separate LAN and SAN network and use FCoE for that dedicated SAN .
Coupled with broad Cisco product portfolio means that customers have the maximum flexibility to tune the architecture precisely to their needs. Cisco product portfolio is tightly integrated, all the SAN switches use same NxOS and DCNM provides seamless manageability across LAN, SAN, Converged infrastructure to Fabric Interconnects on UCS.
From the last 3 blogs lets quickly capture what are the unique characteristics of MDS 9700 that allows for High Performance Scalable Data Center Design.
The IBC (International Broadcasting Conference) opens again in Amsterdam this autumn with Cisco demonstrating advanced solutions that push the envelope of new technologies offering Service Providers new and innovative services to their customers whilst reducing the costs in delivering these advanced services utilizing newer infrastructure architectures.
Cisco’s report on the growth of Internet traffic (the VNI Global IP Traffic and Service Adoption Forecast) declares that by 2018, the world will reach 2.5 trillion Internet video minutes per month. That’s 5 million years of video will cross the Internet each month. The quality of video is also increasing, with 4K video technology now becoming available. Soon this will become mainstream as video Service Providers are gearing up toward providing HEVC across all delivery platforms -- cable, satellite and broadband.
It isn’t just the high resolution services that are changing; the demand from customers to view their content on more and more devices, with differing formats and a more ‘personalized’ experience, is still prevalent. New trends are also starting to emerge. The Internet of Everything (IoE) is an exciting new market for Service Providers to explore and leverage to provide innovative new services outside the traditional delivery of video. Cisco have been at the forefront of the IoE revolution, with John Chambers predicting that IoE will have a significantly greater effect on people’s lives than even the internet has done!
As services provided to customers change, so do infrastructures. An example is the move from large private data centres to Read More »
I speak with many business leaders about “the cloud” and how best to use it to improve collaboration. Quite often, discussions end up getting into specific services and technologies but I always try to ensure that some basic considerations are a primary focus – namely People, Processes and Culture. This video is a great overview and insight into how important it is to get the foundations right, and what questions you should ask before you start looking for a specific solution or ‘technology’.
The Three Considerations
People are your company’s greatest asset and you need to enable them fully and effectively. Increasingly, they “vote with their feet.” They use their own solutions or those provided directly by their departments instead of official IT options (shadow IT). For many reasons public cloud services are a big hit, but you can’t afford for the virtualized environment you have painstakingly created to be used only for functional or legacy workloads. Nobody can afford a discrete, separate underutilized platform -- unappreciated and with hidden value. Read More »
As a Cloud Architect, I’ve had the privilege to work with CTOs and CIOs across the globe to uncover the key factors driving Business Continuity and Workload Mobility across their cloud infrastructures. We’ve worked with enterprises, large and small, and service providers to answer their top five concerns in our new Business Continuity and Workload Mobility solution for the Private Cloud.
1) Can you provide business continuity, workload mobility, and disaster recovery for my unique mix of applications, with lower infrastructure costs and less complexity for my operations teams? Yes.
2) Can you provide a multi-site design that reduces business outages and costly downtime, allowing my critical applications to be more secure and available? Yes.
3) Can my operations teams perform live migrations of applications across sites while maintaining user connections, security, and stateful services? Yes.
4) Does your multi-site solution allow me to utilize idle standby capacity during “normal” operations, and reclaim that capacity as needed during an outage event? Yes.
5) Can your Cisco Validated Design greatly reduce my deployment risks and simplify my design process, saving my business significant time, money, and resources? Yes.
A Proven Multi-site Design, Built on the Most Widely Deployed Cloud Infrastructure
We addressed each of these pain points as we designed, built, and validated our new multi-site business continuity and workload mobility solution. Our multi-site solution is built upon Cisco’s cloud foundation, the Virtual Multi-service Data Center (VMDC) that’s been deployed at hundreds of the world’s top enterprises and service providers. In our latest VMDC release, we’ve extended our cloud design to support multi-site topologies and critical use cases for private cloud customers. This validated design simply connects regional and long-distance data centers within your private cloud to address some critical IT functions, including:
application business continuity across data center sites;
stateful workload mobility across data center sites, will maintaining user connections and security;
application disaster recovery and avoidance across data center sites; and
application geo-clustering and load balancing across data center sites.
Choose the Cloud Infrastructure that Fits Your Unique Business Needs
The VMDC Business Continuity and Workload Mobility solution (CVD Design Guide) is grounded in the reality of today’s cloud environment, providing different design choices that match your applications needs. We realize there is no “one size fits all” cloud design, that’s why we support both physical and virtual resources, multiple hypervisors and storage choices, and security compliant designs with industry certifications like FISMA, PCI, and HIPPA.
