Thanks Jeff, You made it clear in amazing details that anyone can easily follow.

@ebus5 Great question. If one of the cables becomes damaged between the IOM and the Fabric Interconnect, it does not automatically rebalance. Instead, you have to ensure that the service profiles for any blades plugged into slots affected by the outage is configured to also send traffic via the other fabric. If you are not able to fix the IOM port, then you can "reacknowledge" the chassis, which will then rebalance the IOM connections from 4 links to the next lower option of 2 IOM links.

Without a service policy, a blade does nothing, so yes, it's the service policy where you define how many vNICs a blade will have and whether they'll be 1 or 10GB. Your ability to create more vNICs per mezz card is dictated by the number of fabric ports between your IOMs in the chassis and your Fabric Interconnects. Port channeling appears as a single interface to the blade's service policy, so there is no negative effect and is always recommended. Great questions, thanks!

izs125: No, if you have 6 blades, you still have the 1, 2, or 4 fabric port connectivity options for the IOM 2104. If you connect all 4, then you'll just see that ports 3 and 4 will service 3 and 4 and not ports 7 and 8. The number of fabric ports should be based on the throughput needed for your blades. Thanks for the question!

Excellent Video and really well explained. Please release part 3 as mentioned below sir!

[@KenP-207]

Another awesome video. I am looking forward to your new video. Take care.

Amazing session jeff !! thankyou ! When can we expect PART 3

[@JeffreyHallHomestead]

I totally understand and am about to create a brand-new updated whiteboard video for the new 62xx and 22xx hardware for the Cisco UCS. So, I won't need to create a Part 3, instead, it'll be a brand-new video. Expect this very soon! Thanks, Jeff

[@jaashutosh]

Very Well Explained. Thank You Jeff.

traffic excellent video very very clear ...thanks

Arnold Decal: Do you mean the full-width blade? In those cases, they map to both slots (1&2, 3&4, 5&6, or 7&8). You can have any combination of full and half-width blades that fill up the chassis. The full-width blades can have two mezzanine cards, so each one will fill the respective port numbers towards the IOM modules. Hope this helps!

Jeff where is the 3rd Video you mentioned? This is great stuff man, you do know how to simplify the material.

[@arshadgp]

Excellent... Thanks Jeff ! BIG THANKs... Part 3 ?

[@ajaykrsv]

Superb Presentation

[@soljaboy1906]

Are the 2 10GB presented to the blade as 10GB or does it take a service policy to say how many and what speed I want the NIC presented to the blade? I thought that the 10GB was presented to the mezzen card (north facing) and than the service policy told the server how many connections it will have that connected into the south side of the mezzen card( i think thats one two many layers) Also how does port channeling effect pinning in a 2, 3 or 4 uplink scenario?

[@arnolddecal3486]

how about for the full height blade? any port mapping? thanks..btw, nice vids.. :)

[@izs125]

Hello Jeffrey, if I need to configure 5+1 (5 main and 1 backup blades), does that means that my only option is 8:1 over subscription?

[@arshadgp]

Jeff, Part 3 ?

[@layer8man]

@soljaboy1906 I really apologize for not having part 3 posted by now, but it seems like everything that could happen in this past half year did. At this point, I'm planning on doing a brand new series to update the videos using current info. Stay tuned!

[@luisdnunez9677]

thanks jeff is being quite helpfull.

[@soljaboy1906]

dude you got to give us part 3...
