look at your specific array release notes, EMC supports stuff for ages, we still have SCSI attached Symmetrix 3500. You just have to be prepared to pay premium price for extended support. Support for old gear becomes so expensive that it's cheaper to migrate to a brand new platform. If you buy your DAE right now and in 2 years want to migrate to VNX, EMC might buy your array back, don't expect a lot of money back though [IMAGE].
Hi,  We would like to purchase an existing DAE4P enclosure.  We are planning to use it for another 4.5 years.  From the EMC "Release and End of Life Dates" List, we are not able to find that particular DAE.  We would like to seek your advice whether it will be supported for another 4.5 years before we make the decision.  Thanks
End of Support Date for EMC DAE4P ?
