Ask the Expert: Design, Configure, Implement, and Troubleshoot Fibre Channel over Ethernet (FCoE) and Cisco MDS 9000 SAN Switches with Cisco Press Authors

 

This is an opportunity to learn and ask questions about how to design, configure, implement, and troubleshoot Fibre Channel over Ethernet (FCoE) and Cisco MDS 9000 SAN Switches with Cisco expert Ozden Karakok and David Klebanov.

FCoE is an encapsulation of Fibre Channel frames over Ethernet networks. FCoE allows you to create flexible, agile converged networks at the edge and core for multihop FCoE with fast, high-density Cisco Nexus 7000, Cisco MDS 9000, Cisco Nexus 6000, Cisco Nexus 5000 Series switches and Cisco Unified Computing Product Family.

Cisco Storage Networking Solutions covers Cisco MDS 9000 Series multilayer director and multiservice switches.

Hi there,first of all I'd

Hi there,

first of all I'd like to thank you for this great topic and opportunity to get answers from proved experts.

Now, let me describe my challenge: I have working Cisco environment with UCS C series servers connected to N5K (utilizing FCoE) plus block-based storage array: in other words N5K is used as both ethernet and fibre channel switch, with veth and vfc interfaces plus physical FC interfaces connecting storage array. What will be recommended approach when connecting described deployment to environment containing another storage array and non-Cisco FC switch (Brocade)? Goal is to create one VM (that resides on UCS) and enable access to the new storage array (that resides behind Brocade switch).

One idea was to create new VSAN on N5K that will contain two interfaces: vfc from VM and FC port that goes to Brocade switch. Where should I create zoning in this case? Another idea is to use N5K in NPV mode but then I'm losing current zoning and will mean moving storage array from N5k to Brocade, correct? Seems to me there are couple different approaches but I'm not sure what is the best practice.

Thanks,

Dear Tenaro,It is nice to

Dear Tenaro,

It is nice to have you in this forum, thanks for your question.

I see three different options. And you may also want to consider how much disruption you can have in production SAN network. NPV option will always be disruptive. Both Option A & C can be less disruptive, you can provide the traffic separation either via zoning (activate zoning on N5K) or via VSAN. SAN best practices should always be followed.

I hope this helps.

Kind regards,

Ozden

 

Hi Ozden, thanks for you

Hi Ozden,

 

thanks for you reply. However, as an engineer I prefer simple straight forward answers and answer like "SAN best practices should always be followed" sounds more like sales speech.

So let me try and ask same question once more, in slightly different way: if the challenge that I described above was presented to you, what will be your advice to the customer? If you missing some details before you can make final decision, I'll be happy to provide you answers.

Yes, customer prefers less distruptive approach. In addition, customer found some notes in Cisco documentation advising against extending fabric across multi-vendor FC switches. Feel free to elaborate why it is not good to create fabric that consists of Nexus and Brocade switches.

 

Thanks,

Tenaro

Dear Tenaro, I will go with

Dear Tenaro,

 

I will go with option A and that's why it was presented as first option in my diagram.

SAN B is not extended to Brocade fabric, there is minimum traffic disruption. If I were a sales person I would try to convince the customer to use the best in class Cisco MDS switches http://www.cisco.com/c/en/us/products/storage-networking/product-listing.html in his/her SAN network.

SAN best practices can be best explained via white paper or in a book (chapter 6/7/8/9)

hello madam / siras a rookie,

hello madam / sir

as a rookie, i want to ask you about fibre chanel,

where do we can learn about fibre chanel termination, its that on ccnp or ccie

thats all,

thanks

Dear Rizky, Thanks for asking

Dear Rizky,

 

Thanks for asking this question in the forum.

I believe you want to know more about Fibre Channel terminology. On the other hand you wrote "fibre channel termination, its that on ccnp or ccie" so let me answer to both questions.

To learn Fibre Channel from A to Z the best place will be to read Robert W.Kembel's "Fibre Channel  - A Comprehensive Introduction" book http://www.amazon.com/Fibre-Channel-A-Comprehensive-Introduction/dp/0931836107 .If you don't have much time and want to learn it quickly, In our DC CCNA DCICT Certification Guide there is a good summary on the concepts and I also provided many references of good Storage books in the book.

The Fibre Channel concepts are being asked in DC CCNA, DC CCIE Certification exams.

http://www.cisco.com/web/learning/exams/list/dcict.html

http://www.cisco.com/web/learning/certifications/expert/ccie_dc/index.html

And for DC CCNP you need to have DC CCNA or DC CCIE as prereq if I am not mistaken

more on CCNP https://learningnetwork.cisco.com/community/certifications/ccnp_data_center/syllabus/?utm_source=cdc&utm_medium=lnk&utm_campaign=cdc-inbnd

I hope this answers your question.

Please let me know if you need more information or I didn't understand your question.

Thank you,
