install Nexus 1000 v over existing architecture

Hello,

I have got a architecture VMware :

- 2 esxi

- 1 Vcenter server

- Dvswitch configured

Can we install  Nexus 1000 v VEM over dvswitch ?

Is it possible to have dvswitch and Nexus 1000V (VEM) together on the same architecture?

Regards,

André

Hi Andre,

You can surely have N1K + vDS on the same host.

However the VEM uses its own uplink interface and they cannot be on the vSwitch or the vDS. what does that mean, you will need seprate vmnic / interface which will be used by the n1k vem on the esxi host.

Abbharqa,

Now, I don't know very well this architecture, VM/Nexus.

No problem for uplink interface, I have got lot of interfaces  !!

It's for easly migrated the VMs from Vm dvswitch to nexus DVS.

Now, I don't know very well

Andre,

Here is a deployment guide which should help you.

install Nexus 1000 v over existing architecture

Hi,

I have realised the deployment of my nexus 1000v.

Can I connected two VEMs by etherchannel to switch of datacenter ?

VEM Esxi A  > Vnic 7                                              SwA Int  Fa0/1

                                     >>>>>>>Etherchanel>>>>

VEM Esxi A  > Vnic 9                                              SwA Int  Fa0/2

VEM Esxi B  > Vnic 7                                                SwA Int  Fa0/3

                                    >>>>>>>Etherchanel>>>>>

VEM Esxi B  > Vnic 9                                                SwA Int  Fa0/4

On Sw A, All interfaces would in the same etherchannel.

I don't make it,  I afraid a loop !!

Hi Andre,

You would have different portchannels configured for each esx host.  So on SwA you would have 1 portchannel for EsxiA nics only and another seperate portchannel for EsxiB nics only.

Hi,

I have a another problem.

I don't remove a VEM from ESXi 5.0.

I did  :

~ # vem-remove

Please remove host from DV switch or run hotswap script.

~ # hotswap.sh -u

The following switch is of type cisco_nexus_1000v: DvsPortset-2

0x 2. 0. 0. 0

Starting time: Mon Jul  2 14:41:24 UTC 2012

How do for remove the VEM on Esxi server??

Re: install Nexus 1000 v over existing architecture

Hi Andre,

To remove the host you should be able to do it from within the vsphere client once all networking has been migrated back to a vswitch.  Goto inventory->networking, select the nexus dvs, select the host tab, right click on the host and select remove from vnetwork distributed switch. 

Once this is done try running vem-remove -d again.
