Overview of DeviceManager

DeviceManager is a storage management system. Before using DeviceManager, check the validity of the port range used by DeviceManager on the client.

There are two types of products, which provide the converged service and block service, respectively. The converged service includes the file service, object service, and HDFS service. For detailed functions provided by each type of product, see Table 1 and Table 2.

The functions supported by the storage system may vary based on permissions of the imported license.
When Service Type of the converged service is set to Intelligent video and image, DPC, cross-site DR, HDFS, and SmartCompression are not supported.
When Service Type of the converged service is set to Backup and archiving, DPC and the HDFS service are not supported.
When Service Type of the converged service is set to Media, DPC and SmartCompression are not supported.

Menu	Function
Home	Allows you to monitor the cluster and its components and view related information.
Resources	Resources: Namespace allows you to provision and maintain storage resources. Dtree allows you to allocate and maintain dtrees of namespaces. Share allows users and programs to access files on a remote system as if accessing local files. Services allows you to manage services of the storage system. Storage Pool allows you to integrate storage resources on multiple nodes for centralized management. Access: Account allows you to configure and manage accounts that are used to access different services. Multiple accounts can share the same storage hardware resources in a storage infrastructure where various protocols are employed without affecting data security and privacy of each other. Authentication User allows you to create and manage users who are used to access NFS shares, CIFS shares, FTP shares, and the object service. DPC enables upper-layer applications to access storage space more intelligently. Service Network allows you to configure and manage the service networks of the file service, HDFS service, and object service. Tuning: SmartQuota limits the number and size of files in namespaces or namespace dtrees. SmartQoS supports upper limit traffic control and resource isolation at the namespace, client, user, and directory levels. SmartCache stores data on high-performance NVMe SSDs to accelerate data access. SmartCompression allows you to configure compression policies for specified image files to reduce space usage and costs. Dataflow: SmartTier automatically stores data in different locations based on specified policies. SmartSync pushes mass service data to the cloud and pulls the data off the cloud, helping users perform high performance data analytics (HPDA) and back up data.
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. Client Information allows you to view information about FTP, NFS, and CIFS clients and the number of connections on storage nodes. Task Center allows you to view information about tasks created by the system and the task parameters. Data Pilot allows you to retrieve the file or object list using the system metadata or custom metadata fields.
Data Protection	Protection Entity: Namespace allows you to manage data protection for namespaces. Dtree allows you to manage data protection for dtrees. Plans: Snapshot Schedule allows you to create snapshots for namespaces or dtrees at multiple points in time. You can also customize a time policy to automatically generate snapshots. Configuration: Replication Cluster allows you to manage remote replication services in replication clusters. Cross-Site DR: Multiple sites back up each other. When a device at a site is faulty, services can be switched to another site. This solves the problem that the traditional DR center cannot carry services and services cannot be switched over.
Cluster	Cluster: Control Cluster allows you to view or modify the cluster name and view the cluster node information. Hardware allows you to view details of nodes, disks, and ports, as well as manage data cluster modules. Heterogeneous Device allows you to add and manage other heterogeneous devices and establish connections between the local storage cluster and other heterogeneous devices to migrate data to the heterogeneous devices. Network: Network Topology allows you to view the network structure and node information. Diagnosis allows you to manually diagnose the network health status to proactively detect and quickly locate network problems. In addition, the system displays information about the detected subhealthy links. Port and Route allows you to view and configure route information for physical ports, bond ports, and VLAN ports, implementing data transmission across network segments. Lifespan: Lifespan Information Query allows you to view the lifespan information of management nodes and storage nodes, and update information about nodes whose lifespan is to be supplemented, about to expire, or expired.
Settings	Object Service Settings allows you to use functions of the object service when the object service is supported by the storage system. This module is available only when the object service is enabled. Share Settings allows you to set parameters of NFS, CIFS, and FTP shares. By setting this parameter to the account level, all shares under the account take effect. NDMP Service allows you to enable or disable the NDMP service and set a monitoring port. Data Security allows you to configure the global WORM clock, audit log storage policy, and antivirus scan policy. Time Settings allows you to view and adjust the system time settings. External Key Service allows you to configure external key servers to manage keys of self-encrypting storage pools or encrypted accounts. License Management allows you to view license information as well as import and activate a license file. Certificate allows you to view and manage certificates on the current device. User and Security allows you to manage users, configure security policies, configure domain authentication, manage sessions, and set access control. Alarm Settings sends fault information to email addresses, mobile phone numbers, or computers of the related personnel. Monitoring Settings allows you to set monitoring thresholds for performance indicators. If a set threshold is reached, the system will send you an alarm notification. SNMP Management allows you to configure SNMP, query and set system information, or receive system alarms.
