Confused about iSCSI?
Confused about iSCSI?
If you are, this post from NetApp Dave Hitz will probably add to the confusion.
Warning: When you are done reading you might cave in to the notion that iSCSI is ... like a NAS. Because this is the argument that Mr. Hitz is diabolically presenting in that article:
Many customers wonder whether iSCSI is a type of SAN or a type of NAS. I used to know, but not any more.
Is the man loosing it? You'll have to read his post and reach your own conclusions.
Fear not: If after your are done reading the faith in your technical convictions is somewhat shaken I have an antidote.
Reach out for this Dell's view on iSCSI and you will find a technically (and politically) correct explanation of what iSCSI is all about, no tongue in cheek there.

In the comment section of that same blog entry, one of the readers said that if he builds an isolated subnet for his iSCSI, then he thinks of it as SAN, but if he runs it over the corporate network then it is a form of SAN. See http://blogs.netapp.com/dave/TechTalk/2007/04/19/.
Interestingly, I've talked to other customers who applied that same definition to NFS, resulting in the wildly counter-intuitive result that they define NFS on an isolated Ethernet subnet as a form of SAN. (!!!)
I'm not going to try to defend that definition, but I will observe that when people interpret the same words wildly differently, it's sometimes a signal that a breakdown in categories has begun.
