Overview of DeviceManager

Home

Allows you to monitor the cluster and its components and view related information.

Services

Block Service:

• Host allows you to create and manage hosts.
• Host Group allows you to set multiple hosts to form a logical host group for unified management.
• VBS allows you to manage volume metadata.
• Volume allows you to manage storage resources.
• QoS Policy allows you to adjust data flow and properly allocate storage resources.
• iSCSI Service allows you to configure and manage the iSCSI service.

File Service:

• Resource Manager allows you to create and manage file systems.
• Share allows users and programs to access files on a remote system as if accessing local files.
• User Authentication allows you to create and manage local authentication users and user groups.

Object Service:

• Account allows you to create and modify accounts for accessing the object service and set storage policies for the accounts.
• Global Namespace allows you to create and manage regions, clusters, and global domain names.
• DNS allows you to configure the domain name resolution service for the object service.
• Service Network allows you to create and manage the service network of the object service.

HDFS Service:

• Account allows you to view information about the default HDFS service account.
• File System allows you to create and manage file systems.
• Service Network allows you to create and manage the service network of the HDFS service.
• Tiering allows you to create a tiering policy so that files can be stored or migrated to disk pools of different tiers.

Data Protection

Block Protection:

• Snapshot allows you to manage snapshots of storage devices.
• Remote Replication Pair and Remote Replication Consistency Group allows you to set up a replication relationship between the local and remote devices and synchronize data from the primary LUN to the secondary LUN on the remote device. If data on a storage device is lost due to a disaster, data on the other storage device is available, ensuring data security and availability.
• HyperMetro Pair, HyperMetro Consistency Group, HyperMetro Domain, and Quorum Server allow you to implement real-time data synchronization and uninterrupted service access in the event of a fault.
• Replication Cluster allows you to manage HyperMetro and remote replication services.

Object Protection:

• Remote Replication ensures data consistency between clusters in a region and service continuity in the event of a link failure.

Monitor

• Alarms and Events allows you to view and export alarms, logs and details about system events.
• Performance Monitoring allows you to monitor the performance of selected objects by creating performance statistics charts.
• Task Center allows you to view information about tasks created by the system and the task parameters.

Cluster

• Control Cluster allows you to view and modify the cluster name and view information about the selected nodes in the cluster.
• Hardware allows you to view details about servers, disks, and ports.
• Network Topology allows you to view structures of the management network, storage network, replication network, and iSCSI network.
• Storage Pool allows you to integrate storage space of different disks for unified management.

Settings

Object Service Settings:

• Basic Configuration allows you to configure basic parameters of the object service, including Object Service Request Response Namespace, Redirect to upon a Website Access Error, and Account Default Parity Fragments.
• External Service allows you to configure information about the global location service (GLS) and regional location service (RLS), and view or modify the KMS encryption server and authentication information.
• Security Settings allows you to configure security policies for the object service to improve system security.
• Billing allows you to manage billing accounts and billing files.

File Service Settings:

• NFS Service allows you to configure NFS shares by enabling the NFS service.
• External DNS Server allows you to connect the storage system to an external DNS server and access the storage system using an IP address or domain name.
• Domain Authentication allows you to configure AD domain authentication, LDAP domain authentication, and NIS domain authentication.

System Settings:

• Time Settings allows you to view and adjust the time settings.
• SNMP Protocol and SNMP Security Policy allow you to query and set system information and receive system alarms.
• Alarm Notification allows you to specify email addresses, servers, NMSs, or devices at a specified address to which fault alarms are sent.
• Alarm Dump allows you to automatically dump alarms that exceed the upper capacity limit to a specified application server.
• Alarm Masking allows you to select the alarms to be reported.
• Alarm Severity allows you to browse alarms by severity and set alarm severities.
• License Management allows you to view license information as well as import and activate a license file.
• Certificate Management allows you to view and manage certificates on the current device.
• Security Policies allows you to set the user name policy, password policy, and login policy to ensure system security.
• Users and Roles allows you to view and manage system users and roles.
• Domain Authentication allows you to configure the LDAP service and log in to the storage system in LDAP server authentication mode, achieving unified management of user information.
• Session Management allows you to view the current online users.
• Access Control allows you to control the IP addresses that can access the storage system.
