HP VC 1/10Gb - move from 1Gb uplink to 10Gb CX4 uplink

My current setup is

 

Using Share Uplink Sets -

     External Uplink Ports -

              Uplink Set Name "TrunktoCore"

              Bay1 Port 1, Port 2, Port 3, Port 4

              Bay2 Port 1, Port 2, Port 3

              Connection Mode Auto

 

 

Ethernet Networks

     Network Name - VLAN4

             External Ports

             Use Shared Uplink SEts

             Shared Uplink Set "TrunktoCore"

             External VLAN ID : 4

 

  Network Name - VLAN5

              External Ports

              Use Shared Uplink SEts

              Shared Uplink Set "TrunktoCore"

              External VLAN ID : 5

 

 

I would like to use the 10Gib CX4 and remove all the 1Gb RJ45.

 

 

 

I was thinking if I could do it like this

 

Using Share Uplink Sets -

External Uplink Ports -

Uplink Set Name "TrunktoCore10Gig"

Bay1 Port X2

Bay2 Port X2

Connection Mode Auto

 

Ethernet Networks

Network Name - NEWVLAN4

External Ports

Use Shared Uplink SEts

Shared Uplink Set "TrunktoCore10Gig"

External VLAN ID : 4

 

Network Name - NEWVLAN5

External Ports

Use Shared Uplink SEts

Shared Uplink Set "TrunktoCore10Gig"

External VLAN ID : 5

 

 

On each server profile assign "NEWVLAN4" for the Ethernet Network Connections.

 

 

Will the above work?

 

Or is there some other approach

 

Thanks,

Suhail.

If you have a maintenance window I would guess that you could add the two te ports to your current SUS's and then phase out the existing 1G's.  If you want to aggregate the two ports and aren't using Nexus they will need to go to the same switch and LACP will need to be on.

Thanks for the reply.

 

I do not have a maintenance window.

 

Can we assign same VLAN ID number to a new SUS which will have different physical ports?

 

Then I can go one blade at a time and change the server profiles to point the network connections to the newly created network name.

 

I will be aggregating ports-  different VC Module, Same External Cisco Switch.

 

Thanks.

Sure you can assign the same vlan ID to different SUS with different ports. As long as you have unique vnet name, VC will be happy. This is actually how VC active/active design works.

 

Your current config will have some uplink ports as standby because you have one SUS covering both modules so you are using VC active/standby design.

 

the method you mentioned should work but as Psychonaut, you can use the same SUS and same vnet, just first delete old 1G ports and DO NOT apply and then go ahead to add 2 10G ports and then APPLY, that should switch the SUS to 10G ports.

 

I suggest for either way, you should do it at off hours just in case anything happens.
