You configure any storage plan to define up to four different storage tiers, including the ingest tier. To modify an existing service plan to add a new storage tier:
1.On the left side of the Storage page, click on the Service Plans tab.
2.On the Service Plans panel, click on the table row that corresponds to the service plan for which you want to configure a new storage tier.
3.At the top of the panel that opens, click on the Tiers tab.
4.On the Tiers panel, click on the Add Tier button.
The Add Tier wizard opens.
5.On the Transition page in the wizard, use the appropriate fields to set the transition criteria for the new storage tier.
6.Click on the Next button.
7.On the Options page in the wizard, use the appropriate fields to specify:
oWhether to enable rehydration for the new storage tier, and if so, the number of days an object must remain on the ingest tier after it’s rehydrated
oWhether to make this storage tier metadata-only
8.Click on the Next button.
9.Take one of these actions:
oIf in step 7 above, you did not select the appropriate option to make this tier metadata-only, then on the Storage Pools page:
–The wizard displays a table containing a list of all of the storage pools that you can include in the storage tier, along with a check box that corresponds to each storage pool in the list. Use the checkboxes in the left column in the table to select one or more storage pools to be included in the tier.
–A dropdown list box appears next to the name of each storage pool you select. Use these fields to specify the the number of copies of object data that HCP must maintain on each storage pool for each object that’s moved to the storage tier you’re configuring. The total number of copies of object data that must be stored on each pool is the DPL for the storage tier.
–In the Metadata Copies on Primary Storage field, specify the primary running storage MPL for the new tier. This is the number of copies of the object metadata that HCP must maintain on primary running storage for each object that’s moved to the new storage tier.
–At the bottom of the page, select I Understand to indicate that you understand the consequences of moving all copies of the object data to the new tier.
oIf in step 7 above, you selected the appropriate option to make this tier metadata-only, on the Storage Pools page:
–In the Metadata Copies on Primary Running Storage field, specify the primary running storage MPL for the new tier. This is the number of copies of the object metadata that HCP must maintain on primary running storage for each object that’s moved to the new storage tier.
–Select I Understand to indicate that you understand the consequences of moving all copies of the object data to the new tier. In this case, this statement means that you understand that the DPL of the new tier is zero, so all copies of the object data will be deleted for each object that’s moved to the new tier.
10.Click on the Next button.
11.On the Review page in the wizard, review the storage tier configuration settings that you specified in the wizard.
12.Take one of the following options:
oIf the information you entered is correct, click on the Finish button.
oIf the information is incorrect, use the Previous and Next buttons to navigate through the pages of the wizard and make the changes you want. When you’re satisfied with the configuration settings you’ve entered, click on the Finish button.
When you click on the Finish button, the wizard exits, and the Storage page displays the Tiers panel on the service plan configuration page for the service plan for which you’ve just created a new storage tier.
