Tumbleweed

The purpose of a sump is to increase water volume in the system and it gives you a place to hide equipment ie. protein skimmer, heater temp probe. They are very benefical to have if you have the room for one.

From what I understand, they are not necessary, but, as Tumbleweed said, they are a good idea. The greater the volume of water in your system, the easier it is to maintain a specific water quality.
Especially if you're keeping delicate inverts such as coral or anenomes, even a tiny, tiny change in salinity or other mineral concentration, or a too-rapidly-rising nitrogen level, can be devastating to your tank. Extra water volume helps mitigate this, giving your livestock an extra buffer.
