You reference these data services when you define storage requirements for virtual machines and
virtual disks in a storage policy. Depending on your environment, the SPBM mechanism ensures
appropriate storage placement for a virtual machine or enables specific data services for virtual disks.
For details, see Creating and Managing VM Storage Policies.
n
Storage status. This category includes reporting about status of various storage entities. It also
includes alarms and events for notifying about configuration changes.
This type of information can help you troubleshoot storage connectivity and performance problems. It
can also help you to correlate array-generated events and alarms to corresponding performance and
load changes on the array.
n
Storage DRS information for the distributed resource scheduling on block devices or file systems.
This information helps to ensure that decisions made by Storage DRS are compatible with resource
management decisions internal to the storage systems.
Storage Provider Requirements and Considerations
When you use the third-party storage providers, certain requirements and considerations apply.
Typically, vendors are responsible for supplying storage providers. The VMware VASA program defines
an architecture that integrates third-party storage providers into the vSphere environment, so that
vCenter Server and ESXi hosts can communicate with the storage providers.
To use storage providers, follow these requirements:
n
Make sure that every storage provider you use is certified by VMware and properly deployed. For
information about deploying the storage providers, contact your storage vendor.
n
Make sure that the storage provider is compatible with the vCenter Server and ESXi versions. See
VMware Compatibility Guide.
n
Do not install the VASA provider on the same system as vCenter Server.
n
If your environment contains older versions of storage providers, existing functionality continues to
work. However, to use new features, upgrade your storage provider to a new version.
n
When you upgrade a storage provider to a later VASA version, you must unregister and reregister the
provider. After registration, vCenter Server can detect and use the functionality of the new VASA
version.
Register Storage Providers
To establish a connection between vCenter Server and a storage provider, you must register the storage
provider. Make sure to register a separate storage provider for each host in a cluster.
