Hello Jose,

It is difficult to make specific recommendations without knowing your workloads.  It would be better for you and your team to first review the online resources below and then post to this topic if you have any leftover questions.

Most organizations that use the 1000V utilize a 2 vNIC setup.  The 1000V is capable of QoS in the virtual switch itself. So, there is no need to have multiple pairs of vNICs per server.

The number of vHBAs has no relation to 1000V, but most organizations are fine with the bandwidth of 2 vHBAs.

Make sure each vNIC and each vHBA are on different Fabrics: For Example, vNIC0 and vHBA0 are on Fabric A, and vNIC1 and vHBA1 are on Fabric B.

Do not enable Fabric Failover on your vNICs.  Although it is a supported capability, in the event of a failure, using this functionality with vSphere setups will place load on the FI CPU to support the re-mapping of VM traffic.  It is better to have a NIC on each Fabric instead.
