General Distributed Switch Question

I am starting a project where i want to move away from VSS to VDS.  However I have a few questions.

On a host that has (2) dual 10GB NIC in each host.

Currently I have in the VSS setup 2 uplinks for Data and 2 uplinks for everything else.  With using vDS is it best to keep those separate or can it handle that traffic with vlan tagging?

If I keep them together I would use the 4 NIC and LACP them together, but if they need to be separate then I would have to design it another way.  Just looking for input.  Thanks in advance.

When you say "everything else" are you talking about Management, vMotion, Fault Tolerance? Or it also includes iSCSI/NFS traffic? Anyway, depending of your workload you can just create a single vDS with all 4 uplinks and enable Network I/O Control.

No matter if you use 2 or 4 NICs per vDS, avoid the use of LACP, instead of that, use the LBT (load based teaming), see some considerations here: Etherchannel and IP Hash or Load Based Teaming? | Long White Virtual Clouds
