Storage Distance by Protocol – FC, FCoE, and FCIP, Part I

September 9, 2013 at 9:01 am PST

A long time ago I got asked to write about how to use Fibre Channel over Ethernet (FCoE) for distance. After all, we were getting the same question over and over:

What is the distance limitation for FCoE?

Now, the short answer for this can be checking out various data sheets for the Nexus 2000, Nexus 5500, Nexus 6000, Nexus 7000, or MDS 9X00 product lines. But it didn’t answer the most obvious follow-up questions: “Why?” and “How?”

Problem is, whenever you start talking about extending your storage connectivity over distance, there are many things to consider, including some things that many storage administrators (or architects) may not always remember to think about. The more I thought about this (and the longer it took to write down the answers), the more I realized that there needed to be a good explanation for how this worked.

Red_Propeller_Cap_clothing_icon_ID_407Generally speaking, the propeller spins the ‘other way’ when it comes to storage distance.

To that end, I began writing down the things that affect the choice for selecting a distance solution, which involves more than just a storage protocol. And so the story grew. And grew. And then grew some more. And if you’ve ever read any blogs I’ve written on the Cisco site you’ll know I’m not known for my brevity to begin with! So, bookmark this article as a reference instead of general “light reading,” and with luck things will be clearer than when we started. Read More »

Introducing MDS 9710 Multilayer Director and MDS 9250i Multiservice Switch – Raising the Bar for Storage Networks

The data center landscape has changed dramatically in several dimensions. Server virtualization is almost a defacto standard with a big increase in VM density. And there is a move towards world of many clouds.  Then there is the massive data growth. Some studies show that data is doubling in every 2 years while there is an increased adoption of solid-state drives (SSD).   All of these megatrends demand new solutions in the SAN market.  To meet these needs, Cisco’s introducing the next generation Storage Network innovations with the new MDS 9710 Multilayer Director and new MDS 9250i Multiservice Switch.  These new multi-protocol, services-rich MDS innovations redefine storage networking with superior performance, reliability and flexibility!

We are, once again, demonstrating Cisco’s extraordinary capability to bring to market innovations that meet our customer needs today and tomorrow.  

For example, with the new MDS solutions, we are announcing 16 Gigabit Fibre Channel (FC) and 10 Gigabit Fibre Channel over Ethernet (FCoE) support. But guess what? This is just couple of the many innovations we are introducing.  In other words, we bring 16 Gigabit FC and beyond to our customers:

A NEW BENCHMARK FOR PERFORMANCE

We design our solutions with future requirements in mind. We want to create long term value for our customers and investment protection moving forward.

The switching fabric in the MDS 9710 is one example of this design philosophy. The MDS 9710 chassis can accommodate up to six fabric cards delivering:

  • 1.536 Tbps per slot for Fibre Channel   – 24 Tbps per chassis capacity
  • Only 3 fabric cards are required to support full 16G line rate capacity
  • Supports up to 384 Line Rate 16G FC or 10G FCoE ports
  • So there is room for growth for higher throughput in the future …without forklift upgrades

This is more than three times the bandwidth of any Director in the market today – providing our customers with a superior investment protection for any future needs!

Mega Trends are Reshaping Storage Area Networks. But Are You Ready?

The data center landscape has changed dramatically in several dimensions. Server virtualization is almost a defacto in our customers’ data centers with a big increase in VM density. They are also moving towards world of many clouds.  And then there is the massive data growth. Some studies show that data is doubling in every 2 years while there is an increase in the adoption of solid-state drives (SSD). Several of our customers are also either consolidating their data centers or forming mega data centers. All of these mega trends certainly come with increasing challenges for the Storage Administrator as the storage network is becoming more critical as it is the strategic asset in the Data Centers. 

Take a look at this short video with Richard Darnielle (Director of Product Management for MDS Product lines) and me. Richard shares his insights on the mega trends that will shape the next-generation storage networks.

Guess what? Once again Cisco is here to help you on your journey to addressing these mega trends by raising the bar for storage networks. How you ask?

Fibre Channel Standards, Speeds and Feeds, and Generation “X”

March 27, 2013 at 7:24 pm PST

Okay, I have a confession to make.

I’ve been somewhat amused by Brocade’s recent “Gen 5″ Fibre Channel campaign. After all, the idea that “we’re going to simply call 16G Fibre Channel something other than 16G Fibre Channel and pretend that people will not figure out that it’s really just 16G Fibre Channel” is, well, amusing!

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 …
