Demystifying a Small Business Network Dec 18, 2007
Although you can assign specific IP addresses to individual computers (known as static, or unchanging, addresses), most networks use a technology called DHCP (Dynamic Configuration Host Protocol) to assign addresses automatically, greatly simplifying network management.

There is good reason for this, as you don't want your SAN changing IP addresses when you don't expect it, but the company doesn't explain why DHCP is even an option on the 730i.

If you're considering growing your network beyond a client or two and a collection of servers, or adding a DHCP server, you'll need to move on up to a more sophisticated solution.
