The Napkin Dialogues: Lossless iSCSI

March 2, 2013 at 10:14 am PST

What do you get when you cross iSCSI with lossless Ethernet? A lot of confusion.

I do quite a lot of presentations regarding converged networks, including Fibre Channel, whether native or over Ethernet (i.e., FCoE), iSCSI, NAS, etc. The hardest part about these presentations are combating some of the expectations that audiences have, considering they may come from server backgrounds, network backgrounds, or storage backgrounds.

Why is this important? Quite frankly, because like fish who don’t know they live in the water, they have come to grow unaware of their own environmental backgrounds. They tend to forget the assumptions with which they make their decisions. Ethernet and Fibre Channel networking people have very different fundamental philosophies about the way their networks run.

In the world of converged networks, this can cause some, er, unintended consequences.  Read More »

Introducing Nexus 6000 Series – Industry’s Highest Density Layer 2/3 40 Gigabit Fixed Switch

The evolution of the applications environment is creating new demands on IT and in the data center. Broad adoption of scale-out application architectures (i.e. big data), workload virtualization and cloud deployments are demanding greater scalability across the fabric. The increase in east/west (i.e. server-to-server) traffic along with the higher adoption of 10GbE in the server access layer is driving higher bandwidth requirements in the upstream links.

Following up on the introduction of 40GE/100GE on the Nexus 7000 Series, today we unveil the new Nexus 6000 Series, expanding Cisco’s Unified Fabric data center switching portfolio in order to provide greater deployment flexibility through higher density and scalability in an energy efficient form factor.  

The Cisco Nexus 6000 Series is industry’s highest density full-featured Layer 2 / Layer 3 40 Gigabit data center fixed switch with Ethernet and Fiber Channel over Ethernet (FCoE) – an industry first!In addition to high scalability, Nexus 6000 Series offers operational efficiency, superior visibility and agility 

Some say “Nexus 6000 Series is a red carpet platform that will turn heads”. We agree! It’s because of …

CLOUD COMPUTING IS READY FOR YOU. BUT ARE YOU READY?

Previously I talked about the growing demands and how the role of IT has to change from a cost center to a business strategic partner.  And we also looked at the journey you need to take to deliver IT as a Service. Cloud computing is part of this journey and it is happening – and I mean all types of Clouds – Private, Public and Hybrid. In other words, we are entering the World of Many Clouds. Forrester Research recently published a report that concluded, “Cloud computing is ready for the enterprise… but many enterprises aren’t ready for the cloud.”1   Yet cloud deployments are happening, driven by workload virtualization and changes in application architecture and usage.

Take a look at this short video with Paul Perez (VP/GM of Unified Computing System and CTO of Data Center Group) and me. Paul shares his insights on the trends of how Cloud is changing the way of the IT and the challenges you will be facing.

Guess what? Once again Cisco is here to help you on your journey to the World of Many Clouds. How you ask?

The Journey You Need To Take To Deliver IT As A Service

Previously I talked about the growing demands and how the role of IT has to change from a cost center to a business strategic partner.  It’s important to acknowledge that getting an organization to the point where it can implement IT as a Service isn’t easy, nor does it take place all at once.  Every customer has their own journey and different customers will take different journeys.  For some, it’s all about doing what they do now, only more efficiently or perhaps adding new capabilities. For others, it’s about making that full-blown transformation to service-driven IT.

So how do you get there? Each phase expands into a series of key initiatives…

It all starts with moving into more of a unified architecture of network fabric and corresponding operations.

What Is Cisco UNIFIED FABRIC? Why Should You Care?

Is your network ready to help you transform and be the strategic partner that you can be? Let’s face it… Today’s data centers are challenged with siloed resources and facilities… Limited scalability… Poor resource utilization… Growing complexity…Perhaps the biggest challenge is time.  When 80% of your resources are dedicated to “keeping the lights on” and managing all what you have, there is very little time left for innovation that benefits the business.

And the reality is that the role of IT has to change – from a cost center to a business strategic partner!  Why? Because there are increasing demands on IT to help your business differentiate in order to survive and grow in these rough economic conditions. And let’s not forget that the increasing cost pressures, technology changes, and the advent of game-changers like cloud are forcing IT executives to look at how to deliver IT differently. 

These growing demands put even more pressure on the shoulders of IT especially given the current state of your Data Centers. The data center network sits at the core of IT and is key to how IT can deliver services and provide value back to the business.

So what do you do?  The good news is that …
