The latest storage arrays for Security Analytics (SA-STAG8-2U144 and SA-STAG8-5U840) include a special set of MIBs for your SNMP trap server. These MIBs can be downloaded from Dell's support site, but are also provided below. The MIB file available within Security Analytics on the Settings > Communication > Advanced page is strictly for software events and general hardware events on the main head unit.
The Dell models for these storage arrays are the ME4 platform: ME4012, ME4084, ME412, VA012, VA084, VA12
