UCS-C200M2 and 1980s' performance....

[casanavep]

Has anyone deployed UCS on C200-M2  boxes and attempted teaming the onboard gigabit interfaces? I am getting sub-Mbps performance to CUCM 8.5.1 VM deployed using the Cisco prescribed 1000 user template. I have ran the NICs teams and stand alone and get the same result, seriously poor performance. I have a Dell 2970 on the same switch running ESXi and am pulling near wirline gigabit from it. Both are running EXSi 4.1. Both are teamed using route based on IP hash. Even downloads from the ESXi host IP is dead slow.

Hello

What version of CIMC do you have on C200 M2 ?

What is the speed / duplex configuration of the NIC and switch ports ?

There was a known issue with old firmware where LOM ports are stuck with 10 Mbps speed.

Make sure that you upgrade the firmware for all the components using host upgrade utility to avoid above defect.

Thanks for the reply Padma. Running CIMC and firmware associated with CIMC 1.3.2d. Also, both links are negotiaged at 1000/Full. I will read the release notes associated with the recently released 1.3(2i). Any other thoughts?

To know the driver and firmware version

esxcfg-nics -l

ethtool -i vmnicX

ethtool -i vmnicY

verify whether NIC driver firmware is running the latest version using host upgrade utility.

For testing, let us have a standalone NIC interface connected to the switchport. Are there any drops on switch port or NIC interface ?

ethtool -S vmnicX

Tried different cable ?

So, updated my CIMC software which did contain LOM and BIOS updates. Now my DVD drive has disappeared. No longer even shows up as an available drive in BIOS. Gotta love it!

No interface drops on 3750G switch connecting to the VM in etherchannel or stand alone cabled mode. I have been doing test from directly connected to the same 3750G switch

Please open a TAC service request as we need more information about this setup.

Just a quick check. Do you have any traffic shaping configured on egress ports of virtual switch on the ESXi host ?
