vHBA/vNIC placement

Hi,

My blade contain two server types B200M3 with 2 adapters and B200M4 with 1 adapter

When vHBA/vNIC placed automatically

They all placed on one adapter for B200M4 and distributed on the 2-adapters on B200M3

Do I need to have 2 separate placement policies for each of the servers

So to have them on one vCon for B200M3 and to separate on 2 vCons for B200M4, or it will give the same effect ?

Also do I need to place vHBA in above order specially the servers will boot from SAN ?

Thanks

If you assign a service profile with vHBA/vNICs pinned to VCON2 and assign it to a blade that doesn't have a second card the profile will just ignore the VCON2 settings.

Please be aware of the Admin Host Port settings that only apply to the M4 equipment using the VIC 1340/1380:

Hi Steven,

Thank you very much to make me note that.

I do your advise for B200M4 which contain 1 adapter

But how to do vnic/vhba placement for a server with 2 adapter

I put vnic and vhba ports of FI-A on VCON1

then vnic and vhba ports of FI-B on VCON2

And I have 2 vnic with failover on VCON1

When I check VIF path as attached

I found all is ok but the failover ports is going out on path A1 and path B1 which I think is related to adapter 1

So if Adapter 1 come down, then I'll lose this vnics

I think it is because it is one vnic which is on one adapter

So I think to create a second vnic for vmotion for example on the second adapter

But with this, I'll have 4 vnic for vmotion , on A1, A2, B1 and B2

So what do you think ? or it is useless to do that ?

Thanks

thanks
