Microsoft IQNs use the iqn.1991-05.com.microsoft prefix. I'm curious to know, is there a particular meaning to that set of digits. I've seen in other environments that it is referred to as a date - so in this case, May of 1991. And perhaps it's the date (or a date) on which the creator of the IQN was in control of the reversed domain suffix (microsoft.com in this case).
Does anybody know if this is, in fact, why Microsoft iSCSI uses the prefix that it does? Did Microsoft in fact register its domain name in May of 1991? The only other thing I can see that happened in May of 1991 is that Microsoft broke off the relationship with IBM over OS/2 in that month and began developing Windows NT 3.1 in earnest, releasing it eventually in 1993.
Thoughts?
