Subject Vlan and network motification
Date Thu, 14 Jun 2012 18:17:09 GMT

We currently have following setup:

1 cp
1 nic on management network(public IP,
1 nic on the storage network.(private IP.

2 hv(hyperviser server)
1 nic on management network
1 nic on storage network
1 nic on guest network(public IP, direct to the access point,

1 storage
1 nic on storage network
1 nic on management network.

In the advanced network setup, we found out that we can not use the
direct access point, so before we are doing any modification to the
network, we'd like to ask colleagues to help confirm the following

1. The guest network, now it is on the access port, do we need to
change it to trunk port?(with public IP range

2. How many Vlans we need to operate one public shared guest network,
can we config all into the same Vlan, and use it as shared network
port? and create unlimited number of VMs inside this Vlan?

3. In advanced setup, is that really need something of 300 VLan to
operate the cloud?(so how the vlan is assigned, one per client, one
per account, one per guest network, etc?)

Kind regards.
