We have 10 hosts , each with 4 x 10GBe cards in them. We use Dell EMC SC series Arrays (one per DC)
2 Adapters are teamed with an MTU of 1500 running management and VM vLans and vMotion
1 Adapter goes to 1st iSCSI subnet - MTU 9000
1 Adapter goes to 2nd iSCSI subnet - MTU 9000
The 2 clusters are spread across 2 datacenters, but share the same IP space.
The only difference is site A tags the vLAN for iSCSI traffic and site B does not pass vLAN tags
My question is as follows :
I wish to migrate to vDS in part because it is now required for Tanzu on vSphere. Would it be better to create one dVS using 2 x 10GBe adapters for all management and VM traffic and leave the iSCSI traffic on standard switches
or
Create 1 dVS for management + vMotion + vLAN traffic (MTU 1500)
Create 1 dVS for iSCSI (MTU 9000) however, create 4 port groups. 2 tagged for the iSCSI vLAN for site A and 2 without tags for site B.
It has been many years since i've had to do a migration to dVS and am not quite up to speed on what is best these days.
Thank you
