Fabric administrators create storage reservation policies to allow tenant administrators and business group managers to assign the volumes of a virtual machine to different datastores for the vSphere, KVM (RHEV), and SCVMM platform types.
Assigning the volumes of a virtual machine to different datastores allows tenant administrators and business group managers to control and use storage space more effectively. For example, they might deploy the operating system volume to a slower, less expensive datastore and the database volume to a faster datastore.
Tenant administrators and business group managers can assign a single datastore or a storage reservation policy that represents multiple datastores to a volume. When they assign a single datastore to a volume, vRealize Automation uses that datastore at provisioning time, if possible. When they assign a storage reservation policy to a volume, vRealize Automation uses one of its datastores at provisioning time, if possible.
1-Create a Storage Reservation Policy
When you create a storage reservation policy, you are creating an empty container that you use to group datastores that have similar characteristics, such as speed or price.
1-Log in to the vRealize Automation console as a fabric administrator. In my case, I have created one already in my Active Directory with name “firstname.lastname@example.org” and gave permission to configure fabric group during “create Fabric Group” Configuration. Enter the “credentials” and click “Login”
2-Create at least one reservation.
You may choose “My Goal” walkthrough wizard and go to “Infrastructure” tab -> Reservation-s> Reservation Policies -> Click “New Storage Reservation Policy”
Enter a name “VMExpo-Storage-Policy-Tier1” and description “VMExpo Production High End Storage Policy with Storage Disk (FC, SSD) “optionally. Once done, Click the Green check box icon to “Save”
Verify your created storage reservation policy
Similarly, I have created another Storage reservation policy for my Tier2 storage as shown below.
2-Assign a Storage Reservation Policy to a Datastore
After the storage reservation policy is created, populate it with datastores. A datastore can belong to only one storage reservation policy. Add multiple datastores to create a group of datastores for use with a blueprint.
Create a storage reservation policy.
Select Infrastructure > Compute Resources > Compute Resources. Here you can see all your compute resources. Point to a compute resource “RG-Cluster” and click “Edit”.
1-Click the “Configuration” tab
2-Locate the datastore “NFS_DataStore” to add to your storage reservation policy in the Storage table. Click the “Edit” icon.
3-Select your storage reservation policy “VMExpo-Storage-Policy-Tier2” from the Storage Reservation Policy column drop-down menu.
4-Once done, Click on green icon to “Save”.
Repeat the same steps to assign additional datastores to your storage reservation policy. As you can see below, I have assigned all my storage policies to their relevant storages. Once done, click “OK”
