Hello,
Can anyone help me find a suitable ref architecture to add a NFS v4.1 datastore with multipathing on vsphere distributed switch?
Actual configuration:
3 ESXi 6.5 hosts with 2 vDS connected to 4 pSwitches.
1 vDS is connected with 2 10gbe uplink all active NICs to 2 10gbe switches (10GBE VDS)
1 vDS is connected with 4 1gbe uplink all active NICs to 2 1gbe switches (1GBE VDS)
10 GBE VDS is configured with NIOC LBT with the following portgroup:
- fast VMs
- vMotion with vmk2 from each hosts
- vSAN with vmk1 from each hosts
1 GBE VDS is configured with NIOC LBT with the following portgroup:
- normal VMs
- Management with vmk0 from each hosts
Now my customer wishes to add an NFS storage for backup, scratch disk and datastore for testing VMs.
The NAS has 4 1gbe NICs and supports NFS 4.1 multipathing and I don't know what is the best practice for having performance and reliability.
First case:
create a new NFS port group on 10GBE VDS with a new vmk3 vmkernel port and assign 4 IPs on same subnet on NAS
Second case:
create a new NFS port group on 10GBE VDS with 4 new vmkernel ports (vm3,vmk4,vmk5,vmk6) and assign 4 IPs on different subnets on NAS (PVLAN here?)
Third case:
create 4 new NFS port groups on 10GBE VDS with a new vmkernel port each (vm3,vmk4,vmk5,vmk6) and assign 4 IPs on different subnets on NAS (normal VLAN here?)
Or maybe create vmk ports across all vDS (10GBE and 1GBE)?
Thank you very much for any help
