Most significant benefit in 3210 is an expandability. You can use a 2x PCIe ports, for example for FlashCache, 10G Ethernet, 8G FC ports or additional SAS ports.

And why should he / we use Ontap 8 ?
To me this is mostly about 64-bit aggregates. Whether you need them or not is a subject to a discussion - see e.g. this thread: http://communities.netapp.com/message/49508#49508.
On that note:
Be wary that certain configuration maximums are different for 2040 vs. 3210 - e.g. max 64-bit aggregate size is 30TB for the former & 50TB for the latter.
