What is your SAN by the way? StarWind Software R&D
Just a little add: PVSCSI is supported for Windows boot drives starting with ESX 4.0 Update 1, released in November 2009 (VMWare KB Article: 1010398). StarWind Software R&D

VCB is a backup proxy - it provides you with the ability to mount the VM file structures in folders on a Windows Server. The VCB server can be a VM but performance will generally be better if it is a physical machine with a direct connection to your SAN and visibility to the shared LUNS. The Virtual Machine Backup Guide has quite comprehensive instructions on setting this up. I wouldn't say it is simple but it is not terribly complex and you can certainly get both full VM backups of all VM Guests and File level LAN free backups (ie directly over the SAN and offloading from the Guest OS's) for Windows Systems. There's a nice short guide on the basic steps involved on the VMPros.nl web site that covers the main steps needed to get it working. Once you are this far you can write your own scripts (using whatever scripting language you prefer and VCBmounter) to mount the relevant VM files and then just backup the data directly from the VCB server. This is going to be quite painful to manage but it is a cheap way of getting full VM\LAN free backups working. If you want to use the BE 12.5 management interface and have it understand that it is backing up ESX Hosts\Virtual Infrastructure machines then you will have to buy the Backup Exec Agent for VMware Infrastructure. Yep it costs money but it will give you a proper management GUI for the VM's and their content that can handle all backup and restore tasks within a consistent UI. </div> StarWind Software R&D

<div>Exactly - you can have whatever mix of ESX licenses that you want in ESX hosts managed by a vCenter server however the functionality of your infrastructure will depend on the specific spread of licenses - you can only be guaranteed that the functionality of the most restrictive license will be available on all ESX hosts. With the above mix you could have all hosts in a HA cluster with vMotion enabled but wouldn't be able to enable DRS or use Storage vMotion (for example).</div> StarWind Software R&D

Haven't messed with OpenFiler that much, but just because a something says "iSCSI" or "NFS" on it doesn't mean it is necessarily compatible with VMware ESX. VMFS is a clustered file system, and therefore uses locking/reservation features of the iSCSI protocol that are often not available or poorly implemented in many iSCSI implementations (low-end NAS devices for example). If you're running this setup in production, and not just a test lab, I would strongly suggest finding something from the official VMware hardware compatibility list. This will cost money, but there are some less-expensive devices on there. We use OpenSolaris storage on an old box in our VMware lab, because it is cheap. Also we are using HP/LeftHand clustered storage in our test VMware cluster. This isn't ideal, but ponying up $3/GB for the test lab didn't make it past accounting. StarWind Software R&D
I really can't find any reference to ESXi 4U1 supporting your motherboard, it's built in nForce 3 250GB based NIC or your secondary D-Link/Realtek. StarWind Software R&D

Multipathing may be causing your issue. Are you able, and have you tried, to disable multipathing and just have one 1Gb connection to your SAN? VMware may be path thrashing when put under load because of a bad link, or a delay in packet delivery... BTW, your maximum throughput with a 1Gb link is going to be ~30MBytes/sec if your SAN and ESXi host were the only two devices on that link... StarWind Software R&D

You should be fine. To power everything off. Shut down all VM's (apart from the vCenter Server and its SQL server if it's a separate VM). Then put all all the hosts apart from the one running vCenter\SQL into maintenance mode and shut them down. Shut down the VC box and the SQL box (if needed) from an RDP session or using a VI Client session connected to the remaining host. Now shut down the last host. Remember which one this was as you want to restart this one first since the VC server is registered to this host and restarting it is straightforward. To start up again. Power up the last host you shut down and connect to it with the VI Client. Start up SQL (again only if it's a separate VM) and then start up the vCenter VM. Disconnect the VI Client from the single host and connect to vCenter. Now start up your hosts and take them out of maintenance mode. You can begin starting VM's as soon as you have a couple of Hosts running and out of Maintenance mode, just make sure you don't try to start so many that you overload the available host resources before the cluster is back to sufficient strength. </div> StarWind Software R&D

Are your iscsi hba's 1gig or 10gig hba's? But some general suggestions. Make sure you have jumbo frames enabled on the filer, the switch and your vsphere hosts. Make sure you have your virtual guests partitions aligned properly. Do a google on netapp partition alignment and read up if you aren't already familiar with. Another thing you'll want to know before the move is, Are your hosts even fully utilizing and pushing your 1gig (I'm assuming) iscsi network throughput. If they aren't doing this then 10gigs isn't really going to do much. On the filer end of things, check to see how hard it's being pushed right now. Does your filer even have 10gig cards in it? .... </div> StarWind Software R&D

As Anatoly has told you, I think the better way is a complete re-installation, I guess you had clustered your installation? So, if you correctly set your servers, one missing during the operations will be automatically replace by another one on the cluster. In my corporate, we have replace all our VMWare ESX VI3.5 by a VSphere 4.0 with this way. StarWind Software R&D

You can have the VMKernel\Service Console ports and VM Port Groups on the same vSwitch but you should then segregate the traffic using VLAN tagging at the port\port group level. In your case with 4 Nic's the simplest way to do this while retaining some level of redundancy and isolation is to use two Nic's as uplinks for each vSwitch as you are planning to do.

Depends. If you are backing up the VM store, you should be OK if you are using some kind of snapshotting. Otherwise you are backing up inconsistent data anyways. If you are backing the VMs up as if they were real computers, then your backup will probably abort if the VM reboots while the backup is happening. StarWind Software R&D
I think you should to configure 30 vlans on the port on second sesrver (where the VMs will move to) in the same way, as it was on forst one. StarWind Software R&D
