The internal architecture of the Unity system eliminates complex configuration and tuning steps. In our laboratory, we used the Dell EMC UnisphereTM for Unity OE 4.2.1 to:
Figure 13 shows the interface in which you can perform these tasks.

Each physical host must have two host bus adapter (HBA) ports that are zoned to the FC ports of the Unity I/O modules. If the zoning is correct, the host initiators are visible to the Unity module after the hosts are started. Because we are using a virtual environment, we added the ESXi hosts used for SAP landscapes.
To create an SAP host:
The Hosts page appears.
The Add a Host screen appears.
Note: The operating system information is not required, but it allows for more specific configuration and troubleshooting instructions. The network address (name or IP address) is required to customize access to the NFS share.

If the initiator that you want is not in the list, click Create Initiator to add an initiator manually, and then select it from the list of manually added initiators. Click Next.
In Unity All Flash models running OE version 4.2.x or later, all new pools created in the Unisphere GUI are dynamic pools. New pools created in the Unisphere command line interface (CLI) and REST API are dynamic pools by default.
Note: You cannot change the RAID type of a dynamic pool. Also, you cannot shrink a dynamic pool or change its storage characteristics without deleting the storage resources configured in the pool and the pool itself. However, you can add drives to expand the pool.
To create a dynamic pool on All Flash models with Unity OE version 4.2 or later:
The Pools page appears.
The Create Pool screen appears, as shown in Figure 15.

The Tiers page shown in Figure 16 appears.

The Drives page shown in Figure 17 appears, showing the number of flash drives that are needed to support the required amount of storage.

To create and map the volumes:
The LUNs page appears.
The Create a LUN screen appears.
The Configure Storage Characteristics page appears, as shown in Figure 19.
