In SCVMM 2012, in order to have Storage and Load Balance integration you will need the Provider.

For the Storage you will need the SMI-S provider and for the Load Balance you will need their custom provider.

If you are looking for the download links for the SCVMM 2012 Storage and Load Balance Providers, here is the list:

Load Balancer Providers

Storage  SMI-S Providers
* Note: For the SMI-S provider type, a value of “proxy” indicates that you must install the SMI-S provider on a server that the VMM management server can access over the network by IP address or by FQDN. Do not install the SMI-S provider on the VMM management server itself

Now VMM 2012 with SP1, supports the following types of storage providers:

• SMI-S CIM–XML
• SMP

Besides the new SMP provider type, the VMM 2012 SP1 release adds the following new functionality:

• Supports auto (dynamic) iSCSI target systems, such as the Dell EqualLogic PS Series. System Center 2012 – Virtual Machine Manager supported only static iSCSI target systems.
• Supports the thin provisioning of logical units through VMM. Your storage array must support thin provisioning, and thin provisioning must be enabled for a storage pool by your storage administrator
