    Upgrades: Standard switch and iscsi target to distribute switch and vsan

    massimo Lurker

      Hi to all,

       

      and sorry in advance for my English.

       

      Current configuration:

      - 3 x Server Esxi 6.7 in one vCluster in one vDataCenter

      - Each host with 4x 1Gb NICs + 2x 10Gb Nics

      - Each host with 8x SSD

      - About 30 VMs running inside the cluster

      - vCenter's VM inside the cluster

       

      - 10GB NICs still unused

      - SSDs still unused

       

      - 1 standard vSwitch0 with 2 x 1Gb NICs for management and vmotion traffic (crossing active and standby in portgroups).

      - 1 standard vSwitch1 with 1 x 1Gb NIC for iSCSI traffic. (standby NIC removed recently, after an issue with additional NIC)

      - 1 standard vSwitch2 with 1 x 1Gb NIC for VM traffic and different portgroup vlan isolated (standby NIC removed recently, after an issue with additional NIC)

      - Two physical switch 1GB based with 10GB uplink. 2 x 1Gb NIC of each host in first switch. 2 x 1Gb NIC of each host in second switch

      - Two physical switch 10GB based. 1 x 10Gb NIC of each host in first switch. 1 x 10Gb NIC of each host in second switch.

       

      Goals:

      Move to distributed vSwitch

      Move to vSan and dismiss iSCSI target

       

      Now, please can someone help me to understand the best steps to complete the "migrations" with the least number of downs/issues... i hope!

       

      Based on my knowledge, steps in my intentions:

      1. New vDS with 2x 10Gb NIC as uplink and NIOC enabled

      2. New portgroups in vDS, same as in current vSwitch2

      3. Move all VM traffic from vSwitch2 to new vDS. (No more point of failure for VM traffic)

      4. Remove vSwitch2 and add its NIC to vDS as third uplink

      5. New portgroup in vDS for vMotion traffic

      6. Move vMotion traffic to new vDS

      7. Remove one NIC from vSwitch0 and add it to vDS as fourth uplink

       

      Assuming that so far everything is correct, which the next steps?

       

      How to go ahead with vSan and its traffic?

      How manage the vCenter's VM that, i think, cannot be connected to vDS?

      One ore more vDS?

       

      Hope i was clear in my explanation.

       

      Thanks in advance to all.

       

      Regards.
