Storage
This section is used to configure the Global e-mail server.
Global Servers
The lists of all configured server and buckets are shown here.
Server Details
In the Server Details section it is possible to select a server, check its currently used volumes and assign new ones, and finally configure HSM policies.
Data Volumes
After you selected the server, the volumes it currently uses are shown, along with a few configured options. To add a new Volume, click on the NEW VOLUME button.
In the dialog window, provide the basic information of the new volume in the first tab: The allocation type, name, and path.
The second tab depends on the allocation:
Local: decide whether this is a primary, secondary, or index volume, select a compression threshold if necessary, and finally if this will become the new current volume.
External, Sproxy, Centralized: primary, secondary, or index volume, select the type of Object Storage and a prefix to identify the volume. You can set this volume as Centralized, which proves useful in case it will be shared by multiple servers.
HSM Settings
HSM settings are policies for automatically processing objects in the mailstore: e-mails, documents, contacts, and events.
HSM Policies can be scheduled to be run automatically at given times and days; after this operation, deduplication can be enabled to save space in case of duplicated items, by keeping only one copy of an item.
Create a New Policy
The dialog that opens after clicking the NEW VOLUME button allows to create a new HSM policy in a few steps.
In this step, first select to which items the policy will be applied.
Hint
A click on the All checkbox toggles all items at once.
The policy can be applied on the size of the items or on a time interval. in our example, we remove all messages older than 7 days whose size is larger than 20Mb.
We now chose the volumes to which the policy is applied. By default, all the primary volumes are selected. While it is possible to manually specify the volumes from the list, we do not change this.
The last stop shows the settings for review. You can go back to change any options or create the policy.
