Architecting a vRealize Operations Management Solution : Integration : 11.2 Integration Between vRealize Operations Manager and Storage Devices Including VMware vSAN : 11.2.5 Constraints
   
11.2.5 Constraints
The following are constraints of the Management Pack for Storage Devices:
The Management Pack for Storage Devices Solution requires SMART capability to show performance metrics for hardware components.
Some RAID controllers configured in individual RAID 0 mode might not expose all SMART statistics for physical drives. In such cases, the Management Pack for Storage Devices cannot capture and show statistics.
The Management Pack for Storage Devices solution requires SNMP to show vSAN network performance metrics for switches.
The Management Pack for Storage Devices can collect data from IP switches used for vSAN using SNMP only if the switches are configured with sufficient credentials to read switch SNMP data.
