The long awaited mid-range refresh has finally, officially materialised in the form of 3200 series boxes:
The new platforms do offer a lot of goodness, no doubt about it, yet with my usual grumpiness I will ask (rather obvious IMHO) question:
What has dictated the decision to use 4Gbit, not 8Gbit onboard FC ports? If the 3200 series was designed to be 'future ready' (http://www.netapp.com/us/company/news/news-rel-20101109-future-ready.html), then in my view someone overlooked this 'tiny' detail.
I am well aware of an old argument that this is actually very unlikely to saturate even a 2Gbit link under usual circumstances, yet my point is:
4Gbit FC looks, hmm, old school, not future ready I am afraid...
Solved! SEE THE SOLUTION

The original specification I saw was 8GB but then was surprised to see the release was 4GB... I don't think it will be a huge hurdle, but I agree it would be easier to not have to answer the speeds and feeds FUD competitors will give... although we can always add an HBA in the 6 new slots we get with 2 onboard and IOXM One other thing I noticed is the 3200 IOXM is PCI 8x GEN1.0 and the 6200 IOXM is GEN2 (both models onboard are GEN2)..

FAS3200 is 1 ½ U per controller and hence has limited power budget and IO subscription. In the case of FAS3200 we were able to fully subscribe all onboard IO including the IOXM. But if 8Gb FC would have been used we could have either undersubscribed them so they performed more like 4Gb or given something up like onboard SAS or the IOXM. The other downside is we burden everyone’s COGS when not everyone needs 8Gb FC ports.

Agree 100% with your comments - even products like HP EVA 4400 and EMC CX-4 have 8 Gb/s Fibre Channel, its not a matter of if people need it or will ever use it, its the fact the perception that 4 Gb/s Fibre Channel is old technology and deffinietly NOT "Future Ready". (last week Brocade announced 16Gb/s Fibre Channel).
This then allows compeditors sales team have a free hit and sit there and say - look they don't even have 8Gb/s Fibre Channel

Yes, this is exactly what I've heard initially about a year ago. Then in June someone else from NetApp showed me updated spec with 4Gbit ports

Many thanks for your answer - it does make some sense technically now.
The problem is more of a commercial nature though: it is how the product is perceived by an average reader of basic speeds & feeds.
