Hello,  Storage API's is nothing but VAAI and Yes, VAAI is only available for entreprise and enterprise plus and you sould not be worrying about this feature if you are planning in implementing all iSCSI from VNXe because as of now VNXe supports VAAI for NFS with ESXi5 and above.  What is VAAI?  The vSphere API for Array Integration which enables offloading specific tasks to storage array and it requires the plugin from EMC to be installed on ESX.  Please refer this link for more info: Storage APIs   Where can i find VAAI? [URL]  Regards, Srikanth  
Hi, We're almost 90% convinced about purchasing a VNXe3150 for a brand new enviroment which will primarily be used for VMware as well as other storage.  As we're starting off quite small, we're also looking at running the VMware vSphere Essentials Plus kit which is restricted in the number of hosts but also on functionality.  We're looking at the Essentials Plus kit which is much cheaper but still provides the HA and vMotion which we require (see table linked below). [URL]  One thing I have noticed is that the Essentials Plus version doesn't include the "Storage APIs for Array Integration, Multipathing" feature (see table linked above).  My question is, would this have an impact on the overall integration of VMware with the VNXe3150?  If so, how important is it to have this feature and what would we be losing by not having this?  If this is the case, I need a convincing argument to justify the extra spend as this feature only comes with vSphere Enterprise which is a lot, lot more...  Cheers!
