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:


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”

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!

The Napkin Dialogues: Lossless iSCSI

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 …
