Note: This is the third of a three-part series on Next Generation Data Center Design with MDS 9700; learn how customers can deploy scalable SAN networks that allow them to Scale Up or Scale Out in a non disruptive way. Part 1 | Part 2 ]
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.
Cisco UCS M-Series servers have been purpose built to fit specific need in the data center. The core design principles are around sizing the compute node to meet the needs of cloud scale applications.
When I was growing up I used to watch a program on PBS called 3-2-1 Contact, most afternoons, when I came home from school (Yes, I’ve pretty much always been a nerd). There was an episode about size and efficiency, that for some reason I have always remembered. This episode included a short film to demonstrate the relationship between size and efficiency.
The plot goes something like this. Kid #1 says that his uncle’s economy car, that gets a whopping 15 miles to the gallon (this was the 1980s), is more efficient than a school bus that gets 6 miles to the gallon. Kid #2 disagrees and challenges Kid #1 to a contest. But here’s the rub, the challenge is to transport 24 children from the bus stop to school, about 3 miles a way, on a single gallon of fuel. Long story short, the school bus completes the task with one trip, but the car has to make 8 trips and runs out of fuel before it completes the task. So kid #2 proves the school bus is more efficient.
The only problem with this logic is that we know that the school bus is not more efficient in all cases.
For transporting 50 people a bus is very efficient, but if you need to transport 2 people 100 miles to a concert the bus would be a bad choice. Efficiency depends on the task at hand. In the compute world, a task equates to the workload. Using a 1RU 2-socket E5 server for the distributed cloud scale workloads that Arnab Basu has been describing would be equivalent to using a school bus to transport a single student. This is not cost effective.
Thanks to hypervisors, we can have multiple workloads on a single server so that we achieve the economies of scale. However there is a penalty to building that type of infrastructure. You add licensing costs, administrative overhead, and performance penalties.
Customers deploying cloud scale applications are looking for ways to increase the compute capacity without increasing the cost and complexity. They need all terrain vehicles, not school buses. Small, cost effective, and easy to maintain resources that serve a specific purpose.
Many vendors entering this space are just making the servers smaller. Per the analogy above smaller helps. But one thing we have learned from server virtualization is that there is real value in the ability to share the infrastructure. With a physical server the challenge becomes how do you share components in compute infrastructure without a hypervisor? Power and cooling are easy, but what about network, storage and management. This is where M-Series expands on the core foundations of unified compute to provide a compute platform that meets the needs of these applications.
There are 2 key design principles in Unified Compute:
As organizations seek ways to maintain real-time connections with their workforce and customers in an increasingly digital and mobile-centered world, the growth of mobile cloud will be a major force in shaping the business landscape and future tech decisions. The first blog post in this series, by Padmasree Warrior, explores how the convergence of mobility and cloud will deliver unprecedented transformation for all organizations. The second blog post in this series, by Sujai Hajela, answers the question of what mobile cloud really is and how it continues to provide new business opportunities. In the third post, Joe Cozzolino looks at what mobile cloud means for service providers and enterprises. In the fourth blog, Michael Fuhrman discusses the need for end-to-end security in a mobile cloud environment. And finally, this post will discuss actions that CXOs should take concerning cloud technology.
Our recent mobility landscape study showed that organizations are looking for ways to maintain real-time connections with their workforce and customers in an increasingly digital and mobile-centered world. The growth of mobile cloud is a major force in shaping the business landscape and future tech decisions. This blog series explores how the convergence of mobility and cloud will deliver unprecedented transformation for all organizations.
In this final post, Hans Hwang outlines two case studies where clients have used the reach of mobile cloud to improve customer interactions using real-time technology and results and speaks directly to business leaders on how to achieve the results they desire from mobile cloud technology.
In this series, we have covered a lot about what mobile cloud is and its capabilities, but can mobile cloud give you a return on your investment? As a Services leader, I see a lot of opportunity for you to get going with mobile cloud as a differentiator for your business. I’d like to close by talking about business outcomes. What is it you’d like to achieve? Increased efficiency? Reduced operating expenses? More revenue? A better experience for your customers? Or is it all of the above?
Let’s face it: your customers and your boss don’t care what particular technology you use to deliver results. They only care that you get there fast with minimal risk – and without extra funding. Investing in mobile cloud could be just your ticket, so let’s talk about business outcomes.
The appetite for the latest new products and services is growing exponentially driven by the 24 hour, on demand, social media driven, next day delivery expecting, ‘selfie’ posing with the new shiny object, hyper informed consumer. Satisfying the demand for this fast-paced consumer cycle requires manufacturers to move rapidly to stay ahead of competitors and consumer tastes. They must bring interesting and exciting new products to market in a timely fashion, whether they are first to market or responding to a competitor’s new product offerings.
Two specific trends are emerging and transforming how the industry develops, manufactures and meets the demands of the new on demand consumer driving market – crowd sourcing and 3D printing.
Manufacturing Game Changers: Crowdsourcing and 3D Printing
Crowdsourcing is not a new development model. In fact, the open-source model gave us the Linux operating system and the Apache Web server over 20 years ago. But there is one very distinct difference when applying crowdsourcing methodology to a manufacturing process, as opposed to software development, and that is raw material. This is where 3D printing technology is rapidly maturing driving orders of magnitude efficiencies and cost savings into the value chain.
A Printed Car
In fact, a start-up called Local Motors is on the cutting edge of combining crowdsourcing and 3D printing to revolutionize the automobile industry. In a process that Local Motors calls “co-creation,” — also known as “crowdsourcing” — the software allows enthusiasts to post a design for a part that other users in a worldwide community can call up on a browser, see in 3D, take measurements from, and comment on, thus providing a new model and methodology for innovation. Local Motors then leverage 3D printing technology to deploy “microfactories”
Can crowdsourcing and 3D printing produce an electric car?
Cisco’s vision is for an OpenStack-based Intercloud that allows organizations and users to combine and move high-value workloads – including data and applications – across different public or private clouds as needed. Doing so easily and securely, while maintaining essential network and security policies as well as full compliance with local data sovereignty laws, is critical.
Metacloud deploys, operates and manages OpenStack-based production-ready private clouds in any customer data center. Together, Cisco and Metacloud will enable the creation of hybrid cloud environments that combine service provider public cloud deployments with remotely-managed OpenStack private clouds. Bottom line for customers: More agility for less money.
Our customers and partners see the value proposition clearly and have rallied around Cisco’s Intercloud vision and strategy over the last year. Many leading companies are working with us in the adoption of the Intercloud. Among them, key service providers and cloud providers, as well as important technology partners, including Dimension Data, Johnson Controls, NetApp, Red Hat, Sungard, Telstra, and VCE.
Metacloud will become a critical part of our Cloud Services portfolio under the leadership of Faiyaz Shahpurwala.
