I think that me and Anton gave you pretty detailed recommendation, but your plan will work too. Please note that you have no need to use four vlans to connect to SANs.
To learn more please read SAN configuration guide from VMware pubs. Here is for ESX 4.0 and ESX 4.1
Please note that interfaces between StarWind Servers are used for synchronazation channel and used to be bounded and connected directly. Also switches are connected in order to increase fault-tolerance of your system.
First of all - what have you ment by saying "StarWind iSCSI Initiator 5.5"? StarPort or Microsoft initiator?
Could you please clarify what version of StarWind Server are you using and where it was installed in your system?
Hello
Could you provide more details about IOmeter configuration? Outstanding IOps? Disk align, number of workers, etc.?
You can send .icv file that you`ve configured for iometer.
Could you provide more detailed information about your system? What StarWind build are you using? What is the size of Mirror device? Are the mirrors are remote iSCSI targets? Are the firewalls turned off? Could you e-mail StarWind logs to me?
