UCS and vmWare (6.7) with Port Groups

Hi

 

We are new to vmWare. As of now we prepared single vNICs for Management (vNIC1), vMotion (vNIC2) and for VM traffic (vNIC3). These vNICs are configured with failover option in UCS. We found many Cisco as well VMWare articles talking about Port Groups, each Port group defined with pair of virtual adapters. We are looking for more details on Port Groups with respect to UCS and VMWare (do we need to integrate ESXi with UCS, in our scenario with single vNIC do we need to create Port Groups and how this Port Group defined with VMWare & UCS) 

 

Thanks in advance

Port groups are a part of virtual networking at the ESXi level.  I am unsure as to what you mean when you ask whether you need to integrate ESX with UCS.  Please define what you mean there, I think that would be a reasonable place to start.

 

As for failover etc...

 

There are multiple ways to accomplish this.  Failover can be configured at the UCS level with the Enable Failover radio button in the vNIC configuration (this appears to be what you have done.)  Alternatively, you can create two vNICs (one for each fabric) that service the same networks/VLANs.  Do be cautious when adding vNICs with ESX however, there is a known issue in ESX that can cause re-ordering of the PCI bus.

 

Failover can also be configured at the ESXi level in several ways but you should NOT configure failover at both the ESX and UCS level as this can create a race condition during a failover event.
