Storage settings

Identify the Repositories the server can use, define the Purge Settings for the data stored in the repositories, and, when the server connects to an Enterprise Server, review the Disk Array Status for that server.   If your organization uses multiple Data Center Expert servers, and Windows or NFS repository servers for remote storage, each Data Center Expert server should use its repository server: multiple Data Center Expert servers should not store data on the same remote repository.   Disk Array Status tab   View Overall Status and Individual Disk Status information for the disk array associated with an Enterprise Server. If a disk array status changes to degraded, an email is sent to the Data Center Expert Administrators who include an email address as part of their user credentials.   Purge Settings tab Define settings that affect automatic purges, or to manually purge the repositories. You can choose to include the repository data in the backup files created in the System > Server Administration Settings > Server Backup/Restore option.   The Total Repository Usage section identifies allotted capacity (Size) and current usage (Percentage) for each Type of data stored in all repositories, unless Use Remote Storage Only is selected in the Repositories tab. In that case, identifies capacity and usage for all remote repositories, only.   If an error condition occurs at a repository, an email is sent to the Data Center Expert Administrators who include an email address as part of their user credentials. Automatic Purge Settings   Define the settings for the conditions that will cause an automatic purge of the repositories.   Begin Purge: Identify the percentage of total capacity that will initiate a purge.   End Purge: Identify the percentage of total capacity that will cause the purge to end.   Warn of Purge: Identify the percentage of total capacity that will cause the purge to end. Depending on how data is stored, the actual percentage may be below the configured value.   Send Warning Emails: Select to send e-mails to the Data Center Expert Administrators that include an e-mail address as part of their user credentials, when the Warn of Purge threshold is reached.   Apply Purge Settings: Click to save changes to the settings.   Manual Purge   Purge Data Created On or Before: Select the date for which all data stored on or before that date will be purged.   Choose the Types of Data to Manually Purge: Select to include Alarm History Data, Alarm Binary Data, Sensor Data, Untagged or All Surveillance Data, or a combination of these choices, in the manual purge. You can prevent tagged surveillance data from being purged by selecting Untagged Surveillance Data instead of All Surveillance Data.   Run Manual Purge: Click to purge the selected data for the defined range of dates.   Repositories tab   Manage the repositories the server can use, and review information about a selected repository. Local and remote repositories are listed, including each repository's Status, Type, Maximum Capacity, and Conditions.   Details: Identifies the Type, Status, and Condition for the selected repository.   Usage: Information about the current usage for the selected repository, as well as detail about the Type of data that can be stored, as well as the allotted capacity (Size) and current usage (Percentage) for each Type.   A Status Message provides information when something occurred at the server for the selected repository, such as the server went offline, or the an authentication (Username or Password) value changed for a Windows repository. This message appears only when status at the selected repository's server has changed. If the problem persists, contact the Administrator for the affected repository server.   Select Use Remote Storage Only to have the Data Center Expert server limited to using a remote repository, only (disabled when no remote repository is available).   Click Migrate to Remote to migrate the server configuration and repository data currently stored in the local repository to the remote storage repositories.

  CIFS (Windows) mounts do not work when FIPS mode is enabled. MD5 authentication is required for CIFS, which is not supported in FIPS mode. FIPS mode is supported in DCE 8.2.0 and newer. See Server access   At least one remote repository should be defined and used by the server, rather than the local repository.   If your organization uses multiple Data Center Expert servers, and Windows or NFS repository servers for remote storage, each Data Center Expert server should use its repository server. Multiple Data Center Expert servers should not store data on the same remote repository.   You can add, edit, or delete any remote repository, but not the local repository. To delete a repository, select it in the Repositories tab, and click Delete Repository.   Select System > Server Administration Settings > Storage Settings. In the Repositories tab, select to edit or add a repository. To edit a repository, select the listed repository and click Edit Repository. To add a repository, click Add Repository and select Windows Repository or NFS Repository. Configure the Windows or NFS Repository settings. For Windows, specify the NT LAN Manager authentication level: NTLM, NTMLi, NTLMv2, NTLMv2i, NTLMSSP, or NTLMSSPi. For NFS, select the transport protocol, UDP or TCP, and the NFS version: v2.0, v3.0, v4.0, or v4.1. Click Test Repository Settings. An error message identifies why the test failed, if the share settings are defined incorrectly. Configure the File System settings, and click Finish. Use the Purge Settings tab to define when data will be purged from all online repositories that are not in an error or read-only state.

CIFS (Windows) mounts do not work when FIPS mode is enabled. MD5 authentication is required for CIFS, which is not supported in FIPS mode. FIPS mode is supported in DCE 8.2.0 and newer.
