UCS C210M2 NIC Teaming

Hi,

I have 2 x C210M2 Servers with 6 NICs on each Server.

I am looking for some guidance on NIC teaming when using the following VMs

UC

Unity Connection

UCCX

I was intending two use 2 teamed NICs for ESXI and the remaining 4 teamed NICs for the 3 UC applications per Server.

Would it be better to split the the UC aplications/NIC configuration or would the above be suitable.

thanks

Ian.

Ian,

The following link provides recommendations on configuring physical links for UC apps on UCS.

UCS C210M2 NIC Teaming

Padma,

Thanks for responding to my initial query. I had seen this link but it wasnt detailed enough to answer my question.

Cisco UCS C-Series tested reference configurations ship with two or six 1Gbps Ethernet ports (two on the motherboard for C210 or C200 plus on C210 additional four on a PCIe NIC). The recommended best practice configuration when using this tested reference configuration is:

  • One or two pairs of teamed NICs for UC VM traffic. One pair is usually sufficient on C200 due to the low load per VM.
  • One pair of NICs (teamed or dedicated) for VMware-specific traffic (e.g. management, vMotion, VMware High Availability, etc.)

Based on the above would it be correct to have all 3 UC applications (UCM, Unity Connection, UCCX) configured in the same vlan and use 2 pairs of teamed NICs?

The remaining pair of NICs can be used for VMWare.

thanks

Ian.

Hello Ian,

>>> Based on the above would it be correct to have all 3 UC applications  (UCM, Unity Connection, UCCX) configured in the same vlan and use 2  pairs of teamed NICs?

Yes, 2 pairs of teamed NICs ( assuming 1 Gbps ) can handle the traffic generated by above three UC apps.

From ESXi / UCS perspective, having these three UC apps in same VLAN / host is not an issue. However, I am not aware of any application ( CUCM , CUC or UCCX )  specific requirements that demands them to be on seperate VLANs.

>>> The remaining pair of NICs can be used for VMWare.

Yes, you can dedicate a pair for ESXi management.
