Summary: Renewable Energy Agency Deploys Scalable, Power-Resilient Network

With its fast-growing economy, India faces significant challenges in meeting the energy needs of its population and industry. And given the growth of the renewable energy sector, the Indian Renewable Energy Development Agency (IREDA) was established in 1987  to promote, develop, and extend financial assistance for projects involving renewable energy generation, energy efficiency, and conservation. IREDA recognized the need to optimize use of its resources and leverage technology advances to better serve its constituents.

To improve the efficiency of its increasingly complex operations, IREDA sought to replace its aging heterogeneous campus network infrastructure with a scalable, unified solution. Key requirements included superior reliability and security as well as energy efficiency to foster the agency’s values while providing cost savings. There was an immediate benefit in lowering network energy consumption and the network would be the tool to both help ensure the security of confidential information and provide high performance for applications such as video.

How did this renewable energy agency approach deploying a network that would be scalable and power resilient while optimizing network efficiency? Click to read the full blog

Next Generation Data Center Design With MDS 9710 – Part II

EMC World was wonderful. It was gratifying to meet industry professionals,  listen in on great presentations and watch the demos for key business enabling technologies that Cisco, EMC and others have brought to fruition.  Its fascinating to see the transition of DC from cost center to a strategic business driver . The same repeated all over again at Cisco Live. More than 25000 attendees, hundreds of demos and sessions. Lot of  interesting customer meetings and MDS continues to resonate. We are excited about the MDS hardware that was on the display on show floor and interesting Multiprotocol demo and a lot of interesting SAN sessions.

Outside these we recently did a webinar on how Cisco MDS 9710 is enabling High Performance DC design with customer case studies. You can listen to that here.

Three Pillars of ReliabilitySo let’s continue our discussion. There is no doubt when it comes to High Performance SAN switches there is no comparable to Cisco MDS 9710. Another component that is paramount to a good data center design is high availability. Massive virtualization, DC consolidation and ability to deploy more and more applications on powerful multi core CPUs has increased the risk profile within DC. These DC trends requires renewed focus on availability. MDS 9710 is leading the innovation there again. Hardware design and architecture has to guarantee high availability. At the same time, it’s not just about hardware but it’s a holistic approach with hardware, software, management and right architecture. Let me give you some just few examples of the first three pillars for high reliability and availability.

 

Reliability examples in MDS

 

Picture6

MDS 9710 is the only director in the industry that provides Hardware Redundancy on all critical components of the switch, including fabric cards. Cisco Director Switches provide not only CRC checks but ability to drop corrupted frames. Without that ability network infrastructure exposes the end devices to the corrupted frames. Having ability to drop the CRC frames and quickly isolate the failing links outside as well as inside of the director provides Data Integrity and fault resiliency. VSAN allows fault isolation, Port Channel provides smaller failure domains, DCNM provides rich feature set for higher availability and redundancy. All of these are but a subset of examples which provides high resiliency and reliability.

 

Weakest link

 

We are proud of the 9500 family and strong foundation for reliability and availability that we stand on. We have taken that to a completely new level with 9710. For any design within Data center high availability  has to go hand in hand with consistent performance. One without the other doesn’t make sense. Right design and architecture with DC as is important as components that power the connectivity. As an example Cisco recommend customers to distribute the ISL ports of an Port Channel across multiple line cards and multiple ASICs. This spreads the failure domain such that any ASIC  or even line card failures will not impact the port channel connectivity between switches and no need to reinitiate all the hosts logins. You can see white paper on Next generation Cisco MDS here. At part of writing this white paper ESG tested the Fabric Card redundancy (Page 9) in addition to other features of the platform. Remember that a chain is only as strong as its weakest link.

The most important aspect for all of this is for customer is to be educated.

Ask the right questions. Have in depth discussions to achieve higher availability and consistent performance. Most importantly selecting the right equipment, right architecture and best practices means no surprises.

We will continue our discussion for the Flexibility aspect of MDS 9710.

The Cisco RV325 – The newest edition to the Cisco Small Business Routing Portfolio

December 20, 2013 at 12:56 pm PST

Now that the Holidays are upon us, and we look forward to 2014, the Cisco Small Business team continues to raise the Small Business networking bar with the introduction of the all new Cisco RV325. This Dual WAN, 14-port VPN Router, provides all of the same performance, security and reliability of the RV320 launched last June. Both routers are perfect for fast-growing small businesses or branch deployments. So if you are looking for more ports in the same enclosure, the RV325 is the Small Business router to take a look at.

RV320 and RV325

RV320 and RV325

Like the it’s smaller sibling the RV320, the RV325 is a perfect match with the Cisco Small Business SG300 Series Switches and WAP500 Series Access Points. As you saw from my last Blog, the WAP551 and WAP561 boasts a nice feature-set including Captive Portal and Single Point Set-up. The WAP 551/561 are controller-less Access Points meaning additional hardware is not required. The SG300 Series offers a nice blend of features at an affordable price and are designed Small Business. It has most of the features that can be found in today’s Enterprise-class Switches.

This formidable combination makes for the perfect solution for that many Small Businesses and Organizations can take advantage of. Add in our portfolio of award-winning Cisco Small Business Services, and you have a solution that all that guarantees a positive experience from Cisco Small Business Team.

One Option for this solution is the newly launched 200 Series of Smart Switches. There are four new models including 10-, 24-, 26-, and 50-port switches. These Full Power PoE Smart Switches are a great alternative as they offer a generous feature-set, solid performance and even greater affordability.

UCS E-Series: The Survivability Guide | Inside the Branch

Free Cisco learningIt goes without saying (but I’ll say it anyway): reliability is important, as well as ensuring that you have a backup plan to continue that reliability. Just yesterday as I was embarking on my 50-mile commute into the office, I discovered that one of my car tires was completely flat. A spare tire, a standard feature in most cars here in the States, came to the rescue. Knowing how to change the tire myself, now that’s a different story…

In all seriousness, reliability and high availability are especially critical when it comes to keeping your business – including your branch locations – up and running. After all, downtime has disastrous consequences on your day-to-day operations, productivity, customer experience, and revenue. Imagine you’re in a retail environment and the WAN goes down, even for 10 minutes: the Point of Sale (POS) system is kaput, thus transactions are halted, customers are upset, and you’ve just lost thousands of dollars or more in revenue!

So what happens if your server, WAN, or worse, total system, fails? Read More »

What is the longest running item of Cisco equipment in your data center? Can you beat 13 years?!

June 18, 2012 at 4:33 am PST

Where were you in 1998? Somewhere in one of our customers, a customer booted one of our 3640 routers, and it’s been running ever since without a reboot!

It’s been running since last century! Wow.   It’s been running since around the time my daughter was born, and a good few years before my son was born!  It’s been running longer that some of our competitors have been in existence, and longer than Juniper Networks has been a publicly traded company!

I learned this from an email was passed around my office, that highlighted this remarkable evidence of reliability.  It made me wonder, in your data center, what is your longest running piece of Cisco data center equipment?

And it also reminded me of some of our best practices for network reliability, such as Cisco Smart Services, described in this short VoD:

So now for the evidence.  As you can see from the “show version” Cisco IOS output below ……
