Can V8 and V6 run on the same machine using different ports?

I'm not using fault tolerance. It's a single server and using .ibv files.

I see that V8 uses .swdsk files for VDs and V6 uses .ibv files.

Is there a performance difference between the two?

What will happen to the .ibv files during the upgrade?

V8 allows cache larger than 512MB, can the cache size be changed on the old VDs after the upgrade?

When you say the upgrade from V6 to V8 can be done with no downtime, do you mean that the upgrade can be done without shutting down the VMs and nobody will notice anything?

OK, I meant "netsh int ipv4 set subint "SAN" mtu=9000 store=persistent" not 1500.

The Netgear 10GbE switch I got suppose to support Jumbo frames

I'll try it and get back with results as soon as I can.

OK, I just need to look at all the possibilities just in case.

Also, is it better to use the Intel driver Jumbo Packet of 9014 option or to use the Windows command: netsh int ipv4 set subint "SAN" mtu=1500 store=persistent? I tried the Windows command and seems to cause problems.

Would I be able to downgrade if V8 didn't work?

How old is V8 and will V8 install seamlessly over V6?

NIC teaming not supported with iSCSI: is that the case even when using Intel's software?

In addition, I created a RAM drive on the SAN the test shows that I am getting about 9.4Gbps write and about 3.2Gbps read.

What could be the problem?

I have a new SAN server and having poor read performance on all VMs and a test Windows server. SAN network is a 10Gbe LAN with just the 2 servers connected to a Netgear XS708E 8-port 10Gbe switch. I originally had the servers connected together using crossover cables and performance did not change. ...
