"Weight" hosts in cluster

[abergman89]

Hi,

I have two bladechassis, one with 10 GbE  network connections and one with 1 GbE connections, the servers inside is the same model and configuration.

The plan is to have the two chassis om the same cluster, for the hardware redundancy, I would prefer to place as many machines as possible in the chassis with 10 GbE and use the "1 GbE" as last resort. Is it possible to add "weight" to the servers in a cluster? Do I event want to do that?

Are the 10GbE connections used for VM traffic only, or storage as well? How is the networking set up?

There are ways to accomplish what you ask, but I woud let DRS do its thing and monitor the VMs for a while. If there are issues, then maybe pin certain VMs to certain hosts, etc. I would personally try to use the default settings and not complicate the setup unless necessary.

The 10GbE connections is used for all traffic, the two chassis is connected to each other via 10GbE uplinks and a ToR switch, but each chassi also have their own switches and all traffic between hosts/vms in a chassi will use the internal switches.

Do DRS take things as bandwidth, latency etc in consideration when moving VMs?

You would likely want to look at Stroage DRS and Network I/O Control as well.
