Cisco UCS Configuration - x9508 chassis and 210c M7 blade configuratio

[Ketanshirsathe11]

Hello There, 

I am new to Cisco UCS technology and trying to configure Cisco UCSx9508 in our environment hence I have some question on configuri g chassis and port connectivity

1. Do I need Cisco Nexus switch to connect Fiber Interconnect ? If yes any document for reference

2. How to configure fiber Interconnect port ?

- server port 

- network port 

- FC port 

Any reference link.

Thanks in advance

The Cisco UCSx9508 is intended to be connected to a UCS Fabric Interconnect (not a Fiber Interconnect) and the UCS Fabric Interconnect (FI) connected to the upstream network (Can be Cisco Nexus switch, but other switches work fine usually.)

In this topology diagram "Chassis 1" can be a 9508 and "FI A" and "FI B" would be a 6400/6500 Fabric Interconnect.

Depending what management model you want to use follow the docs:

• UCS Intersight Managed Mode (IMM) (SaaS/cloud managed), follow IMM docs from Intersight.
• UCS UCSM Managed Mode (UMM) (Local managed), follow UCS UCSM docs.

The ports on the chassis itself are not configured directly. The ports on the FI (Fabric Interconnect) facing the 9508 chassis should be set as a "Server" port. The ports on the FI (Fabric Interconnect) facing the upstream network/FC-SAN should be configured as "Uplink" port.

If you have gone through the docs and have specific questions, feel free to ask.

Thanks Steven. This information would help me.

Hi,

In order to create port channel ethernet uplink port in UCMS,  Is there any configuration need to be similar in order to communicate with network switch

Nw switch : Juniper QFX5120

On the UCS side follow the [Uplink Ethernet Port Channels] docs which on the UCS side amounts to:

1. Configure port as uplink port
2. Create port-channel
3. Add port to port-channel
4. Done

What needs to happen on the upstream side is create a standard/vPC/MCLAG port-channel.

Any Cisco CVD details what that switchport/port-channel configuration needs to be on a Nexus switch.
Adapt accordingly to whatever the Juniper configuration needs to look like.
(Not Juniper support, so not exactly sure what configuration works or doesn't work.)
Would be an excellent resource if you could post your Juniper configuration /sanitized if needed/ once you get it working so others know what Juniper configuration should work with UCSM Fabric Interconnects.

Thank you Steven !!

Is it possible to have connectivity between fabric Interconnect 6454 to IFM module (x9508) and fabric extender (Cisco 5108)

To give brief background 

We have new chassis x9508 which will be configuring from scratch also from other site we have current setup of Cisco 5108 chassis (count-3) so we are planning to migrate those 3 chassis in new setup 

We are planning to use FI 6454 for both connectivity IFM and fabric extender 

Also would like to know any major consideration or practice to be followed during pre-migration and post migration

The 6454 Fabric Interconnect supports both new 9508 and elder 5108 chassis per the spec sheet:

• https://www.cisco.com/c/dam/en/us/products/collateral/servers-unified-computing/ucs-b-series-blade-servers/6400-specsheet.pdf

See section "5108 Blade Chassis Server Connectivity" as some IOMs/FEXs are not supported.

Be sure to decommission the servers and decommission the chassis from the old UCS domain.
Should be able to connect up to the new Fabric Interconnects and discover just fine.

Thanks Steven

I have configured the fabric interconnect 6454 

I have couple of issues in configuration 

1. I need to change the hostname of fabric Interconnect during time of configuration subodinate fabric interconnect (secondary) took same name 

2. I run show cluster state command on primary FI

Both FI are showing Up 

Following status is showing 

HA not ready

No device connected to this fabric interconnect 

I have validated the L1 -L1 and L2-L2 physical connectivity between FI and FI to chassis 

Pls suggest how to rename the name of fabric interconnect and fix the HA issues

[Ketanshirsathe11]

Sure. I will post juniper configuration once will get it
