Hi guys, I see that is possible to mix IOM6 with IOM12 using the correct version of Ontap that allows this and a lot of examples of adding new IOM12 shelves on existent IOM6 stacks (very common since IOM6 was discontinued)   But I don't see examples of adding old IOM6 shelves on existent IOM12 stacks.   Example: Current: Fas2750+1 shelf DS224c Plan: Fas2750+1 shelf DS224c+1 shelf DS2246 at the end.   Is it possible? Any additional comment?   Thanks!               ... View more

Hello,   I am thinking about upgrading the complete FAS2750 stack we have from IOM6 to IOM12. Does anybody have any experience with the performance increase when doing this? The SAS and SSD disks we have do all support 12 Gb/s, only not the SATA shelf. I am wondering or it's worth the money to upgrade all IOM6 to IOM12 modules. In theory there should be a 100% perofrmance increase isn't it?   Regards, Maurice ... View more
