A few questions about setting up my NAS to my Virtual enviroment with ISCSI

I have an ESXi 6.0 HOST with several Windows and Ubuntu guest sitting in an ASUS essentio cm1630 (quad core AMD 3.2 and 16 gb's of DDR3 1 TB internal spinner used as my datastore). I want to attach my new QNAP TS-231 NAS with 1 3 TB Red WD in it for now but plan to expand. I want to be able to create a few ISCSI targets to my guests. The way I have it set up right now is I have 1 500 GB target and 1 TB target attached via SCSI initiators mounted on my windows 7 guest and Ubuntu 14 guest. Its working ok but I want to get some thoughts including speed, reliability and best practice. I don't have any data on the drives right now so I can scrap the whole plan and start from fresh if needed. The NAS has 2 NICS the PC only has 1. I do have a switch I just bought I could use if needed (TP-LINK TL-SG108 8-Port 10/100/1000Mbps). I plan to not raid anything since its only 2 bays and use crash plan as an offsite backup of the NAS.  My goal is to familiarize myself with ESXi and VMware while running a small media server for my family. Any suggestions?

Hi,
One thing I learned about iSCSI best practices is to set a dedicated ip range for the iSCSI netwotk.
Or to use a dedicateed switch, or doing vlan, but the theory is to separate iSCSI network from the LAN. If not, Lan devices and resquests could suffer from iSCSI, and iSCSI could suffer from Lan.

Do you use software or hardware initiator? Hard is not supported on all NIC, but will consume less host cpu.

On top of that for example you have several method to create dedicated VMKernel ports for iSCSI, I could tell you what I do but the best way to be sure is to look at vmware documentation on vsphere 6 (vsphere storage guide) :
https://www.vmware.com/support/pubs/vsphere-esxi-vcenter-server-6-pubs.html 

You could take a look at EE articles too, the leader in this style seems to be Andrew Hancock, in fact everything I read from him was really accurate and helpful. Here is his article for iSCSI on vsphere 5.5 :

Your biggest bottleneck will be the single disk in your NAS.

You may want to experiment by using NFS and compare it with using iSCSI.

also remember to use Jumbo Frames, e.g. a frame of at least 9000, which will help for performance.

see my EE Article

HOW TO: Enable Jumbo Frames on a VMware vSphere Hypervisor (ESXi 5.0) host server using the VMware vSphere Client

This is also applicable for 6.0, you already have a link to my other article, on Best practice for iSCSI and Multipath.

if possible create a storage network, which is just for storage.
