I am trying to figure out an ideal setup for an ESX environment running on a QNAP NAS to get optimal iSCSI throughput and redundancy.
I was thinking of the following setup.
QNAP with 4 x 1gbit and 2 x 10gbit ethernet
2 x ESX host with 4 x 1gbit and 1 x 10gbit ethernet
2 x 24 port switch (1gbit)
1. Attach ESX host directly to NAS on the 10gbe interface. This interface is reserved for iSCSI communication. If possible I want to avoid buying 2 10gbit switches.
2. Attach ESX 1gbit interfaces to the two switches. Two on each swtich
3. Attach NAS 1gbit interfaces to the two switches. Two on each switch
On ESX I define the 1gbit interfaces as failover iscsi communication in case the 10gbit link goes down.
Is such a setup feasible? Could I increase throughput through LACP on the 1gbit interface? How would I need to configure them?
