We're currently in the "research" phase for moving to the NetApp platform, and I have a few questions related to the upgrade paths between the E-series and the FAS-series. If we purchase an E2624 and chain 3 or 4 DE5600's off of it (24-bay expansion enclosures), and then later decide we're ready for the more advanced features in the FAS line, can we buy a FAS2200 head-unit and attach the previously purchased DE5600's to it? Or even possibly down-grade the E2624 to a DE5600 and attach it as an add-on enclosure to the FAS2200-series as well?
The issue is that we're yet to the point where we can justify the cost of the FAS-series, but don't want to sink the money into our existing product (Dell PowerVault) line if we eventually plan to upgrade to NetAPPs FAS line.
Currently it's not possible to migrate between FAS and E-series , since both of them are differ in OS/Software -( Eseries -san tricity FAS - Ontap)
But the upgradation of integrating both is in progress, Probably netapp guys can comment on it
