What is Dynamic FCoE?

May 15, 2014 at 12:25 pm PST

96588998_47It’s been a very busy few weeks. The Data Storage Innovations (DSI) conference, the Ethernet Summit conference, EMCWorld, and next week at CiscoLive, I’ve been starting to talk about a new concept in Data Center storage networks called Dynamic FCoE. Understandably, there have been a lot of questions about it, and I wanted to try to get this blog out as quickly as possible.

The TL;DR version: Dynamic FCoE combines the best of Ethernet Fabrics and traditional deterministic storage environments to create massively scalable and highly resilient FC-based fabrics. If you thought you knew what you could do with storage networks, this takes everything to a whole, new level. Read More »

Two Resources on Nexus Programmability

April 28, 2014 at 4:50 pm PST
Class is in session

Class is in session

As I start to explore more and more information about Software-Defined Networking and Programmability in the Nexus portfolio, I’ve been fortunate that there have been a lot of people helping me learn along the way.  I thought I’d share some of these as it gave me a bit more insight into some of the more holistic perspectives that I’ve been trying to get my head wrapped around lately.

I’m still starting off at a rather high level, though I’m spending more and more time getting deeper into the tech. Every once in a while, though, I need to look up and make sure that I’m swimming in the right direction. It’s really easy to get mired in the details and forget the bigger picture. Read More »

Cisco Live US 2014 : Looking Forward to Great Sessions on Storage Networking (FC and FCoE)

April 23, 2014 at 7:00 am PST

Cisco Live 2014 is fast approaching in few weeks from now.
This is an important year for Cisco Live as well as Fibre Channel (FC) along with Fibre Channel over Ethernet (FCoE) family of products. For Cisco Live : it is celebrating 25th anniversary on its home ground – Bay area, San Francisco. For Storage Market, Next Generation MDS product family lineup with 16G linerate FC and 10G FCoE support has renewed the energy in SAN industry with large customers building Green field Datacenters using new 16G FC and 10G multihop FCoE. This year has seen lot more traction on multihop FCoE; new set of customers now include Aerospace, Financial and Technology solution companies.
More details can be found here under Case studies.

BhavinyadavI asked Bhavin Yadav, from the engineering team, to bring his technical  expertise and knowledge of the customer’s needs  to help us create a catalog of the sessions you don’t want to miss at Cisco Live San Francisco .

“This year at Cisco Live, we have lot more focus and sessions on both SAN technologies -- Fibre Channel (FC) and Fibre Channel over Ethernet (FCoE). Once the registration is finished, you can subscribe to the sessions and put it on your calendar as well. The Cisco Live Smart Mobile apps launching on April 28th will also help us drive to the right session using our smart phones.
In April 2013, a little while before last year’s Cisco Live 2013 in Orlando, Storage business unit of Cisco released its next Generation Fibre Channel Director class switch MDS 9710 and Multiservice Fabric Switch platform MDS 9250i. By now, most of us know that MDS 9710 is designed to support 16G linerate FC and 10G FCoE using its FC and FCoE Linecard modules. MDS 9250i is a 2 RU switch that gives us all the flexibility we need in terms of multi-protocol support, whether it is FC / FCoE / FCIP or ISCSI. MDS 9250i has 16G FC Line rate ports with 10G FCoE, 2 x 10G FCIP ports along with iSCSI support as well. This is like a Swiss army knife – you can use it anywhere (backups, storage migration, etc.) for any of the mostly used protocols (FC, FCoE, FCIP, ISCSI) in Fibre channel industry.

This year, we are bringing in more than 20 sessions to the storage track in various flavors, ranging from Learning Storage Fundamentals, Design, Deployment, Operation, Troubleshooting, Best Practice, Migration, etc. Let me highlight some of the important sessions for Storage experts. This will help you quickly identify, reserve your spot and get most out of the Cisco Live 2014 for storage focused technology experts.

Storage specific sessions:

BRKARC-1222 - Cisco MDS9000: expanding the family:
This session presents detailed analyses of the new members of the market leading MDS 9000 family, demonstrating their performance, reliability and flexibility. Topics include architectural design and enhanced capabilities of Cisco MDS 9710 and MDS 9250i, their typical use cases and interoperability with the other MDS 9000 family members as well as Nexus switches. This session is designed for storage engineers involved in FC and FCoE network design and Data Centre storage architecture. An understanding of FC switching technologies and FCoE benefits is assumed.

2 hours Technical Breakout – Presented by Adarsh Viswanathan

BRKSAN-2282 - Operational Models for FCoE Deployments -- Best Practices and Examples:
Converging SAN and LAN traffic onto common infrastructure enables customers to realize significant cost efficiencies through reducing power consumption, cooling costs, adapters, cables, and switches. FCoE/Unified I/O also provides additional flexibility through a wire-once model that allows ubiquitous access to block storage from all servers.. This session will help customers determine the FCoE operational model for their organization to successfully share a Converged Network between LAN and SAN teams. Best practices, case studies, and configuration examples will be provided, based on experiences with Cisco customers who have successfully implemented FCoE. The session covers operational management for FCoE deployments on Nexus 5000, Nexus 6000, Nexus 7000, Nexus 7700 and MDS.

90 min Technical Breakout -- Presented by Jason Walker and Santiago Freitas

March 10, 2014 at 9:37 am PST

ZKIn his paper  “A Data Center Fabric  is Critical to the Next Generation of Data Center ” published on January 2014,  Zeus Kerravala (@Zeeman)  wrote  ” The data center has gone through many major evolutionary changes over the past several decades, and each change has been defined by major shifts in architectures…in 2011, another major shift began: the shift to a virtual data center.  This has been the primary driver in enabling customers to transition to the cloud and ultimately IT as a service…Next-generation data centers will see a greater coupling of hardware and software to bring together both physical and virtual infrastructure. The result will be a fluid, dynamic “fabric” capable of moving IT resources where the business needs them.”

End of January at Cisco Live Europe, Cisco introduced new solutions “Data Center and Cloud Networking Accelerations Continues” expanding the portfolio of data center fabric solutions designed to create this virtual data center.

On March 11, a  panel of experts shared  the best ways to achieve this shift . You can  access here to the recording
