we are going to use vmware vsphere 6.0 for everything in our environment
and we already have VNX 5400 and our VNX work now with fiber connection
the question is my manager want to change and he want to use ISCSI
so i need advice is really now ISCSI better because the Ethernet switches has 10 G speed
personally i had from long time ago problems to fix and troubleshot iscsi storage with Solaris servers so from that time i don't like Iscsi
now i want real good advice and especially for v sphere it is better to use fiber or ISCSI and why ?
