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

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.

Next Generation Data Center Design With MDS 9710 – Part I

 

High Speed (16Gbps) and High Capacity (384 Line Rate ports per Chassis)

Data centers are undergoing a major transition to meet higher performance, scalability, and resiliency requirements with fewer resources, smaller footprint, and simplified designs. These rigorous requirements coupled with major data center trends, such as virtualization, data center consolidation  and data growth, are putting a tremendous amount of strain on the existing infrastructure and adding complexity. MDS 9710 is designed to surpass these requirements without a forklift upgrade for the decade ahead.

MDS 9700 provides unprecedented

  • Performance - 24 Tbps Switching capacity
  • Reliability -- Redundancy for every critical component in the chassis including Fabric Card
  • Flexibility -- Speed, Protocol, DC Architecture

In addition to these unique capabilities MDS 9710 provides the rich feature set and investment protection to customers.

In this series of blogs I plan to focus on design requirements of the next generation DC with MDS 9710.  We will review one aspect of the DC design requirements in each.  Let us look at performance today. A lot of customers how MDS 9710 delivers highest performance today. The performance that application delivers depend

How does Cisco Access Switching help address BYOD, Mobility and Security Needs?

November 11, 2013 at 5:45 am PST

Cisco will host a live webcast on Wedn November 13, 2013 to discuss BYOD, mobility, security and how Cisco access switching address these customer needs. If you are reading this blog, there is a good chance that your work is somehow related to these critical areas. To test how widely BYOD, mobility and security impact IT professionals, I’ve used an unscientific way to check it out on several popular online IT web sites. I want to see if they consider at least one of these areas to be their main focus.  Here’s what I’ve found – many of them (although not every single one) are devoted to at least one area.

Cisco @ Interop – It is All about Solutions that Solve Problems

Usually at shows like Interop Las Vegas 2013, attendees wander around the show floor looking at all the new products that are coming out from vendors. Now it is always exciting to see the latest and greatest technology coming out, but very often there is so much information to consume it is difficult to envision how these new products will solve problems that IT organizations are facing today.

Cisco is taking a different approach at Interop this year. In the Cisco booth there are a number of demo stations including the traditional new product demos, ask the experts stations, trivia games and many more, but in addition there are two unique demos the “Your NOC Your Way” Demo and the Unified Access Experience Demo that take a solution perspective to addressing top IT concerns.

1. The “Your NOC Your Way” Demo

This unique demo focuses on how Cisco solutions can aid in addressing the top concerns of network operations managers. Read More »
