What about iSCSI, FCIP, FCoE, CIFS, NFS, NAS, FC etc.. and more acronyms than a reasonable person should be asked to ingest? It's such a good question that I will write a blog article about it and try and make some sense of what it means and why it is important.

I have a small infrastructure. It's around 70 hosts, 12-15 of which are actually connected to the SAN. I've got around 20TB of raw storage in two EMC AX4-5s, and I'm using FC. This is just to let you know that I have no idea about what I'm going to ask ;-) I've spoken to people who have much larger SAN infrastructures than I do, and the people who run ethernet based SANs (be it FCoE or iSCSI) have all said that their SAN traffic is completely segregated from their networking traffic. None of them do any sort of complex routing, certainly not over WANs, and I haven't heard of anyone doing anything with IP based firewalls or the like. I assume you speak to more storage engineers than I do, so are these features that people are using? Is the 10GbE solution only speed related, or are people taking advantage of the flexibility of the platform, or are they treating it like FC, just faster and with copper cables?
