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
After recently receiving my new 3270 controller pair I had a few suprise's...
There is an additional issue which I either missed when reviewing the documentation or is possibly not mentioned at all. The issue I speak of is that with the new 10GbE interconnect (HA Active/Active) change there is no longer 4 onboard fibre channel ports available per controller. If you wish to cluster a pair on 3200's series arrays you will only have two 4GbS FC ports per controller pair. While I understand that an FC card can easily be added to expansion ports this seems like a glaring issue for those of us who wish to use our new 3200 as a multi-purpose SAN/NAS box. Plus this goes against existing best practices which state that FC target traffic should be isolated to either a single card or the local FC ports but not both.
I'd also like to get feedback on how others are planning on using the two local SAS ports built into each controller. With the cabling diagrams I've reviewed as well as the best practice documents I see no real use for them unless I wish to build out a non-redundant SAS stack. In my environment this is not an option since uptime and performance is my main concern.
