There is an EMC document titled Storage Target Revisions and Adoption Rates. This lists the operating codes that all EMC hardware should be running at. These may not always be the latest revisions of the code but is the revision that EMC reccommends be running on your array. The document is updated about once a month it seems and is located at:
The current target for FLARE 29 is 04.29.000.5.003.
@Roy: Are you not able to find FLARE release notes using this powerlink menu selection?
There are two docs, one for the 28 brach and another for 29 branch.
About whether at all to move to FOE 29, is there a compelling reason presented to you from EMC or any that you discovered for this decision? Perhaps the Release notes' Fixed problems section will help you decide.
Oh, all those servers aren't SAN attached. There are only about 80 SAN attached servers. I just listed the datacenter count as we all have to share the same maintenance window.
I am taking my Cx4-480 to Rel 29 for that reason as well, the improvements to VMware integration make it worth it in addition to the updated features to VP. I have a Cx3-80 that is being upgraded to a Cx4-960 and that will be on rel 29 as well.
