I have a tricky question and need your advice
UCS customer, using ESXi 5.1 and vswitch, no DS nor N1k
NFS with multiple shares on the same Netapp Filer
ESXi and Netapp are on the same Vlan and IP subnet
With standard balancing setup (originating virtual port ID), the VMkernel interface sends actually traffic over one outbound interface (VIC-1240) to a single NFS share
Statement from VMware:
It is also important to understand that there is only one active pipe for the connection between the ESX server and a single storage target (LUN or mountpoint). This means that although there may be alternate connections available for failover, the bandwidth for a single datastore and the underlying storage is limited to what a single connection can provide. To leverage more available bandwidth, an ESX server has multiple connections from server to storage targets. One would need to configure multiple datastores with each datastore using separate connections between the server and the storage. This is where one often runs into the distinction between load balancing and load sharing. The configuration of traffic spread across two or more datastores configured on separate connections between the ESX server and the storage array is load sharing.
Question from customer
For e.g. 2 NFS Shares on the same Netapp filer, how can loadbalancing be changed to make use of the second uplink interface ?? if the same VMkernel interface is used for both NFS shares, all the traffic flows over one interface.
We know, that IP-hash isn’t possible; FI doesn't support LACP
