Hi Pasi,

Can I have more information about your topology ?

- Number of physical and virtual servers per SAN (if it's possible).

With Equallogig by Dell, there is two controllers but 1 active an 1 passive, so if I understand, you have bonded all NIC (3) by controller to obtain 3 Gbit/sec?

In my case, I want to use 3 physical servers and 1 SAN to manage 10-15 virtual servers.

What is the best solution : ISCSI (1Gb/s) or Fibre Channel (4Gb/s)?

I've been using Equallogic iSCSI SAN storage for years without problems.
It's n*1 Gbit/sec, you can scale it with multiple NICs and dm-multipath.

I don't see any reason to go for FC nowadays, unless you have some special 

What kind of device are you using ?

Equallogic PS series arrays.
