Load Balancing with Dynamic FCoE

July 8, 2014 at 6:00 am PST

It may sound strange to hear me say it, but when I wrote the previous blog post about Dynamic FCoE I thought that it may get a little blip of attention and then filed away as a “oh, that is cool” little factoid about Cisco’s storage portfolio. Perhaps I shouldn’t have been so nonchalant, but I confess I was not expecting the number of questions that I (and other speakers at CiscoLive back in May) have been getting about the technology.

Many questions – including some in the comments of the previous blog – have indicated a strong desire to know more, and they have been excellent and well-thought out. I’m going to try to address some of them in a deeper dive blog whenever I can, in the hopes of being able to address some of the concerns and clarify some points.

switch goes downWe’ll start with one of the biggest concerns – sharing the spine layer for logical separation of SAN A/B, and what happens if one of the spine switches (nodes) go offline. 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

Top Things to Know About DFA Before Cisco Live Milan

January 24, 2014 at 2:15 pm PST

Two weeks ago, I presented a webinar on Dynamic Fabric Automation (DFA) and went over the allocated 1 hour to cover the content.  Yesterday, as I was doing follow up with a hands-on demo, I went over time too. This illustrates how rich DFA is, and how much there is to say about it! Dynamic Fabric Automation is an environment for data center automation that is centered on the CPOM (Central Point of Management), a set of services that are provided with the new Data Center Network Manager (DCNM) release 7.0(1).

The services available on the CPOM provide the following:

  1. Power On Auto Provisioning (POAP)
  2. Inter-switch link connection verification
  3. A single console for configuration
  4. Network Auto-Config Profile provisioning
  5. Message processing for external orchestrator
  6. Automatic host provisioning
  7. Embedded management for network monitoring and data collection

All of these services are provided using standard protocols and applications. For example, the POAP service uses DHCP, TFTP and SCP/SFTP, but using a combination of templates and a very intuitive and easy-to-use GUI, DCNM provides a simplified and systematic way of bringing up your data center fabric. The inter-switch link validation or cable consistency check allows the operator to verify the fabric connections against a predefined template and prevent unexpected connections to come up.

The Jabber process provides the single console for configuration, statistics and troubleshooting. Using any XMPP client, an operator can “chat” with the fabric devices; this approach offers the possibility to organize devices in chat groups that match their role, their location or simply some administrative set. With XMPP, a single command can be sent to multiple devices in a secure way.

The most important element of the CPOM is certainly the network profile provisioning. Read More »

Introducing Cisco Unified Fabric Innovations: Cisco Dynamic Fabric Automation, Nexus 7700 Switches, and F3 Modules

Cisco today introduced Application-Centric Infrastructure as the vision for Next Generation Data Center architecture, built for both today’s physical and virtual workloads as well as tomorrow’s highly dynamic Cloud-based, and performance-intensive big data application environments. Please check out Padmasree Warrior’s blog or Cisco Unified Fabric to learn more.  

What I would like to share with you is how we are evolving the Cisco Unified Fabric to deliver operational simplicity through superior integration.

Introducing Cisco Dynamic Fabric Automation (DFA)

Delivering Operational Simplicity through Superior Integration

As organizations accelerate private and public cloud deployments, IT organizations and data center networks must evolve to meet rapidly changing and growing requirements.  Virtualized and cloud environments require more agility and simplicity to quickly deploy and migrate virtual machines. IT organizations, on the other hand, are challenged with operational complexity, architectural rigidity and infrastructure inefficiency with manual processes, disjointed provisioning, deficient software overlays, static resource allocations and disruptions when growth is needed.

The good news is that Cisco continues to evolve its Unified Fabric to address these needs. The new Cisco Dynamic Fabric Automation delivers unsurpassed operational simplicities through superior integration. It does this by …. Read More »
