Hi Smokey22, Welcome to the forums and sorry for the late reply.  You can find if your system is supported by navigating to our E-lab navigator.   You can get to e-lab by following Home > Support > Interoperability and Product Lifecycle Information > E-Lab Interoperability Navigator  on powerlink. You can search via your model array or use one of our Wizards to narrow your search.  But from what I've seen on e-lab ESX 4.x is not supported on our cx500 model arrays. But I do advise upgrading your flare to the latest release avalible for the CX series which is flare 26.  All of which you can download from powerlink if your array has been registered to your account if performing the upgrade yourself. Click here for documentation to create customizable documentation on upgrading.  Or you can contact your Service Account Manger to arrange a site engineer to schedule the upgrade with you.  Thanks,
Hello,  Newbie here so please bear with me [IMAGE]  A site we manage has a CX500 array that is still within warranty. We would like to upgrade the sites VMware infrastructure to vSphere 4.0 Update 2 as the ESX 3.5 suite is nearing EOL. VMwares HCL does not list the CX500 as supported. We are not worried so much about support per say, but would like to verify if the SAN is compatible and potentially supported if needed. If FLARE or other components need to be upgraded, we can accomplish that with minimal impact.  Can anyone provide information as to what I would need to do to get answers to the compatibility question and what we would need to do moving forward?  Thank you for your time.  V/R,  Chris
