The DiskXtender Container option is selected as the storage type for the archive folder to be created.
If the DiskXtender Container storage type is selected, the following fields must be defined:
1. In the Archive Location field, specify the path to the volumes for this folder. To change the location, click Browse and select a new path to the volumes. The maximum number of characters for the Archive Location field is 1024.
When specifying the path in the Archive Location field, you can specify that path as a UNC path or a local path.
Refer to “Common guidelines for specifying archive location paths” in the EMC SourceOne Email Management Administration Guide or the EMC SourceOne Email Management Console Online Help for guidelines on when to use each type of path. 2. In the Maximum Volume Size (MB) field, specify the maximum size (in MB) of
individual volumes in this folder. The default value is 100 MB. You can change this value to be from 10 MB up to 10000 MB (10 GB). When a volume reaches the maximum volume, it is closed and a new volume is created.
If you set the Maximum Volume Size (MB) field to a value greater than 2048 (2 GB), you will receive a warning indicating that this may make your archiving and retrieval operations take longer.
If you are planning to use DiskXtender to write EMC SourceOne files to an EMC Centera device, change the maximum volume size to 90 MB, instead of the default size of 100 MB. There are known performance issues when retrieving volumes of 100 MB and greater from an EMC Centera device. Setting the volume file size to 90 MB allows for slight overflow of the volumes before they are closed, while keeping the total volume file size to under 100 MB.
Refer to “Best practices for setting the volume size” in the EMC SourceOne Email Management Administration Guide or the EMC SourceOne Email Management Console Online Help for additional guidelines on setting the value of the Maximum Volume Size (MB) field.
3. Specify how long data in the archive folder should be retained by entering a value in the Months to retain field.
Valid values for the Months to retain field are the following: • The default value is 1, indicating 1 month.
• The minimum value is 0, indicating that no retention is specified. If 0 is selected the Enable automatic disposition field cannot be used.
• The maximum value is 1200 (indicating 100 years). Consider the following before specifying this value:
• If you are storing the data in the archive folder on a NAS storage device that supports data retention, you should be aware of the data retention settings on that device, if any. You should also be aware of the maximum time of retention
supported by the device, as this differs by device. Refer to “Retaining and disposing of archived data” on page 113 for more information on data retention and disposal.
• Retention should not be enabled on archive folders used for SharePoint External BLOB Storage (EBS). For these folders, the Months to retain field should be set to 0. Refer to “Archive folder requirements for SharePoint EBS content” on page 95 for other requirements for archive folders that contain EBS content.
4. Specify whether to allow EMC SourceOne to automatically dispose of data in the archive folder. Select the Enable automatic disposition field to specify that EMC SourceOne should automatically dispose of data in the archive folder when the data is older than the value specified in the Months to retain field. Refer to the section on retaining and disposing of archived data in “Retaining and disposing of archived data” on page 113 for more information on data retention and disposal.
5. Select the type of media to be used by DiskXtender in the Media Type field. This media type must match the type selected in your DiskXtender configuration.
6. Specify the path the DiskXtender local extended drive in the DiskXtender local extended drive path field. This path should contain the drive letter and the path, such as
E:\EMC SourceOne\Five Year.
7. Select the Purge after move option if you want the files purged immediately after they are moved to media by DiskXtender.
If you do not select the Purge after move option, you should configure purge rules using the DiskXtender File System Manager Administrator as described in the DiskXtender for Windows documentation. Purging files is usually needed to avoid running out of space on the storage drive.
8. Select the Direct Read option if you want files to be read directly from media rather than first being copied back to the extended drive and then read.
If you are using DVD-R or DVD+R media, files are not marked for direct read or purged until you finalize the media.
EMC technical representative to determine if this strategy is appropriate for you. Refer to “Configuring Native Archive folder DiskXtender options” on page 97 provides more information on using EMC SourceOne with DiskXtender.
9. Click Next. The Indexing page of the New Archive Folder wizard displays and is described in “Using the Indexing page of the New Archive Folder wizard” on page 84.
Using Centera containers for storage
The Centera Container option is selected as the storage type for the archive folder to be created.
If Centera Container is selected as the storage type for an archive folder, the following fields must be defined:
1. In the Pool Address field, specify the one or more addresses to be used with the Centera device. The address may be specified using the host name, such as mycomputer.emc.com or can be specified using the dotted decimal format, such as 8.10.444.122. To specify multiple addresses in either form, separate the addresses with a comma (for example, node1.emc.com,node2.emc.com).
Note: A best practice is to use the host name address form if possible so that if an IP address changes for a machine, the Pool Address field value will not need to be changed. Instead, the change can be made at the DNS server or in the local hosts file. Using host names also makes more sense in a disaster recovery scenario.
Click Test Pool to verify the addresses in the Pool Address field are correct and currently reachable. Any problematic addresses will be identified for you to correct. 2. Specify how long data in the archive folder should be retained by entering a value in
the Months to retain field.
• The default value is 1, indicating 1 month.
• The minimum value is 0, indicating that no retention is specified. If 0 is selected the Enable automatic disposition field cannot be used.
• The maximum value is 1200 (indicating 100 years). Refer to the section on retaining and disposing of archived data in “Retaining and disposing of archived data” on page 113 for more information on data retention and disposal.
Consider the following before specifying this value:
• If you are storing the data in the archive folder on a Centera storage device configured to support data retention, you should be aware of the data retention settings on that device, if any. You should also be aware of the maximum time of retention supported by the device, as this differs by device. Refer to “Retaining and disposing of archived data” on page 113 for more information on data retention and disposal.
• Retention should not be enabled on archive folders used for SharePoint External BLOB Storage (EBS). For these folders, the Months to retain field should be set to 0. Refer to “Archive folder requirements for SharePoint EBS content” on page 95
older than the value specified in the Months to retain field. Refer to the section on retaining and disposing of archived data in “Retaining and disposing of archived data” on page 113 for more information on data retention and disposal.
4. In the Maximum Volume Size (MB) field, specify the maximum size (in MB) of individual volumes in this folder. The default value is 100 MB. You can change this value to be from 10 MB up to 10000 MB (10 GB). When a volume reaches the maximum volume, it is closed and a new volume is created.
If you set the Maximum Volume Size (MB) field to a value greater than 2048 (2 GB), you will receive a warning indicating that this may make your archiving and retrieval operations take longer.
Refer to “Best practices for setting the volume size” for guidelines on setting the value of the Maximum Volume Size (MB) field.
5. Determine whether to enable Enable File Audit Deletes. When enabled, EMC SourceOne labels all file deletions it makes on the Centera device with a string. By default, the file audit delete string is set to EMC SourceOne. You can change this to another string by entering another string in the File Audit Delete String field. 6. Click Import to import a Pool Entry Authorization (PEA) file for use with the Centera
device. A file selection dialog opens to allow you to select the PEA file. Once selected, this configuration is entered into the PEA Configuration area.
The PEA file allows access to data on a Centera storage device. Refer to the EMC Centera online help for more information on creating and using PEA files.
7. Click Next. The page of the New Archive Folder wizard displays and is described in “Using the Large Content page of the New Archive Folder wizard” on page 82.
