This videos seems to be focused on blade. What about UCS rack server?

Thank you very much for this video, very interesting and helpful. But I have a question. You stopped adding leaf switches at 128 because 128 its the number of ports in your spine switches. I know 6k is a large number for servers, but what if you are running a really big data center, and need more leafs? you just buy bigger spine switches? I am aware that there exists bigger chassis switches, though but they're quite expensive.

Hello Brad, and thatnk you for your video! I have a question regarding the diagram involving the Rack Server. Wouldn't its connection be: Management and Data through the FEX and then one cable from the FEX to the FI? I ask this because it would follow the architecture you can see in the chassis (internally connected to the FEX and then one single cable transfers management and data to the FI's). Thanks!

@tanvirahmedmp5198 7 жыл бұрын

+petebeast- If that would be the case, then you would use the rack as a blade, which technically anyone wouldn't do it seeking statelessness of a blade server.

I'd like to hear or see a discussion on the challenges of non symmetrical dynamic pinning across the FIs where port throughput is impacted and how we can better manage this without impacting fault tolerance.

Great Video Brad! Do you happen to know a reference that shows where firewalls or virtual firewalls should go in this architecture?

Brad - I just looked at your diagram in this video and noticed that you have the FEX's cross-connected across the FI's, which is technically incorrect. All IOMs from the first chassis should connect to FI-a and all the IOMs from chassis 2 should connect to FI-b.

@kernelpanic19 9 жыл бұрын

***** Actually Brad has it right. Each chassis has two IOMs, one connected to the A fabric and one connected to the B fabric to enable failover. If a chassis were connected to a single FI, the loss of that FI would disconnect all the servers in that chassis from network and storage. There is a lot of documentation on this, here is an older document that has a basic diagram (you'd want to look at version specific documentation if you're doing actual config). www.cisco.com/c/en/us/support/docs/servers-unified-computing/ucs-manager/110202-lan-san-connectivity-ucs.html

I got confused by that. At 6:06, the right hand side "FEX" is referencing the 2248 nx-os, while the UCS "FEX" on the left, chassis 1, is referring to the "UCS FEX"

Can "End Host" mode and "Switch" mode be configured port-wise on the the 6100 hundred or is it implemented globally, that is the whole box will either work in "end host" mode or "switch" mode.

@mohammedelhassanhabiballa5700 3 жыл бұрын

Globally, The FI must be globally configed as either EHM or SM.

Brad a query from me. Does the VM uses VMXNET3 Vmware drivers for the virtual adapters provided by PALO adapters or the Cisco PALO adapter provides a different set of drivers?

Hi Brad, I'm Tony and I have been watching your Cisco UCS tutorials. I'm a currently a Data Center Technician but my goal is to become a DC design architect. I was wondering if you had any advice in reference to courses I should start with. Thanks again and your great videos are very helpful.

In 2.1 ate least, in Switch mode, if Zoning is enabled on on the VSAN, UCSM creates zoning for you based on your initiator group policies you define for the vHBAs. This is actually very easy to manage.

Hi,master!can you do some practical configuration video of real devices with step-one-step to show us but not only the illustrates,that would be greatful~gratitude,good technology speech!

Totally awesome information. With the new 6200 series fabric interconnects, can you run a VPN link from the 6248 to a pair of non-multichassis etherchannel capable switches such as two Cat 4500's or HP 4208vl's? A sales engineer told me today that it was possible but i'm not convinced. fingers crossed for a response...
