Hi to all,
we are running the following configuration since late 2008: We have 2 server rooms on two different floors. In each room we have 2 PowerConnect 5424 and one EQL PS5000. The system is completly redundant. The 2 switches in the rooms are configured identically as:
- Spanning tree enabled
- No VLAN
- iSCSI disabled
- Flow Control enabled
- Jumbo frame enabled
- Port g17-g20 defined as LAG 1 and connected to the other local switch
- Port g21-g22 defined as LAG 2 and connected per fibre to the switch located in the other server room
The switch is handling just all of the iSCSI traffic. We are using VMWare ESX / vCenter to accessing the EQL.
What i want to do now is to seperate the iSCSI and the vMotion traffic (as recommended by VMWare). Therefore i would need two seperate VLANs (as far as i can figure out). What would be the best way to do this? I already found some hints on this forum, but there is no "Best Pratice" or something like that.
Port 1-14 for iSCSI (10.3.33.x, 255.255.255.0)
Port 15-16 for vMotion (10.3.34.x, 255.255.255.0)
Port 17-20 LAG 1 (local stacking)
Port 21-22 LAG 2 () No need for communication between iSCSI / vMotion iSCSI and LAG1 should be in VLAN (10)?
vMotion in VLAN (20)?
How to configue the lag groups 1+2 to push the seperated VLAN information to the other switches? I'm a bit more familar to the configuration of our HP switches we use for the rest of our the networking and in my opinion they are a bit easier to configure for VLANs as the dell do.
First of all I want to clarify something: do you need help with VLANs and LAGs configurng or some best practice advices?
To configure trunking on LAG between switches you need:
As far as I understand you have square topology, it may lead to suboptimal traffic flows. It's just my observation:)
