When you install Site Recovery Manager you have to do Inventory Mappings from DC site to DR site. Inventory Mappings includes Network Mappings, Folder Mappings, Resource Mappings, Storage Policy Mappings. All of the Mappings require for proper management and configuration of virtual machine at DR Site.
Storage Policy Mapping is very useful when you are using storage policies for your virtual machines. Storage policies place virtual machines in the vCenter Server inventory and on datastores according to rules and tags that you define in vCenter Server. If you map storage policies on the protected site to storage policies on the recovery site, when you run a recovery plan, Site Recovery Manager places the recovered virtual machines in the vCenter Server inventory and on datastores on the recovery site according to the storage policy that you mapped to on the recovery site.
In this post we will see on How to configure Storage Policy Mappings in Site Recovery Manager Step by Step:

Login to vSphere Web Client.
Go to Site Recovery Manager.
Expand the Configure section.

Click Next.
Step 6:
Review the Mappings you have configured.
Click Finish to create Storage Policy Mappings.
As you can see that Storage Policy Mapping is created successfully. It is listed below.
That’s it we have successfully created Storage Policy Mappings for Recovery site. So Now Site Recovery Manager will place the recovered virtual machines in the vCenter Server inventory and on datastores on the recovery site according to the storage policy that you mapped to on the recovery site.
This is an optional step, If you are not using any storage policy then you can skip this mapping.
Once you have configure Storage Policy Mappings, we have to configure Placeholder datastore in SRM:
