Switch zoning configurations for the NetApp E-Series system include fabric zoning, target port sharing, host splitting, and controller splitting.
The NetApp E-Series system has no zoning limitations.
The NetApp E-Series systems present themselves by default to a Lenovo Storage V7000 system as a single WWNN system with a WWPN for each port zoned to Lenovo Storage V7000. For example, if one of these storage systems has four ports that are zoned to Lenovo Storage V7000, each port appears as a controller with four WWPNs. A given logical unit (LU) must be mapped to Lenovo Storage V7000 through all controller ports that are zoned to Lenovo Storage V7000 by using the same logical unit number (LUN).
The controller must be separately zoned to Lenovo Storage V7000 ports for exclusivity requirements.
For robustness, dual fabrics is the minimum requirement.
Zone controllers individually. Lenovo Storage V7000 must have unique access to the LUNs.
Also, for robustness the NetApp E-Series controller fabric zone contains all the Lenovo Storage V7000 ports and at least one port from each of the NetApp E-Series storage systems controllers.
The NetApp E-Seriesstorage system supports LUN masking to enable multiple servers to access separate LUNs through a common controller port. To guarantee the necessary unique LUN access, use explicit masking with Lenovo Storage V7000.
Host splitting can be used. With hosts that connect to Lenovo Storage V7000 and the controller, Lenovo Storage V7000 must have sole access to its LUNs. There might be MPIO interaction considerations. For details about the supported host multipathing, see the following site:

Controller splitting is supported. Lenovo Storage V7000 does not need exclusive access to the controller. Explicit mapping is required for LUN exclusive use by Lenovo Storage V7000.
As Lenovo Storage V7000 is not aware of any other use of the controller, performance might be affected.
