Cisco UCS – Configuring the FC uplinks and port channel

To provide the external SAN access to the UCS environment, it needs to be connected to FC SAN switches or the Storage box which  supports the FCoE. Traditional infrastructure will be still using the FC SAN network as a centralized storage.  If you would like to connect the UCS domain to an existing SAN network, you have to configure the FC uplinks ports on fabric interconnect. you can also configure the port as FCoE where you can directly attach the storage which supports the FCoE.

Before Continuing the article , Please see that how to set the port mode in Fabric Interconnect.

Option:1

Configure the port FCoE (Only for DAS- Direct attach storage):

1. Login to the UCS manager .

2. Select the equipment pane and navigate it to Fabric Interconnect – > Fabric Interconnect A – > Fixed Module – > “Un-configured  Ethernet ports” – > Select the port (Which you want to configure as FCoE).

Confiure as FCoE Storage port
Configure as FCoE Storage port

 

3. Repeat the same for Fabric Interconnect – B.

4. Connect the storage in to the FI’s FCoE port which we have configured.

UCS Domain  - DAS
UCS Domain – DAS

 

Option : 2

Verifying FC uplinks ports: (To connect to the existing  SAN )

1. Login to UCS manager

 

2. Navigate to the Fabric Interconnect – > Fabric Interconnect A – > Expansion Module – > Uplinks FC ports.

3. Verify for the Fabric Interconnect B’s Expansion modules as well.

Configuring the port channel for SAN: (Optional)

A Fibre Channel port channel allows you to group multiple physical Fibre Channel ports  to create one logical Fibre Channel link to provide fault-tolerance and high-speed connectivity(link aggregation). You can create up to four Fibre Channel port channels in each Cisco UCS domain. Each Fibre Channel port channel can include a maximum of 16 uplink Fibre Channel ports.  (From www.cisco.com notes)

1.  Go to the “SAN” tab and then “SAN Cloud->Fabric A->FC Port Channels->Right Click and ‘Create Port Channel’”.

Configure port channel - SAN
Configure port channel – SAN

 

2.  Then give the port channel a name.

Configure port channel- SAN
Configure port channel- SAN

 

3. select the appropriate ports and select finish .

Configure port channel - SAN
Configure port channel – SAN

We have successfully configured the SAN port channel .
