Viewing System Information

Procedure

1. Click Home.
   

   The functions supported by the system and the actual GUI vary depending on the imported license or selected service type.

2. In the Basic Information area, view the current system version and SN. When deploying a converged service, you can also view the current service type.
3. View the number of main resources, bandwidth, and IOPS of the system.
   • Converged services:
     • DPC Nodes: number of DPC nodes.
     • NFS Connections: total number of storage nodes connected to all NFS clients. It is associated with performance metric NFS Connections.
     • CIFS Connections: total number of storage nodes connected to all CIFS clients. It is associated with performance metric CIFS Connections.
     • HDFS Concurrencies: total number of requests sent by all clients. It is associated with performance metric HDFS Concurrencies.
     • Object Concurrencies: total number of requests sent by all clients. It is associated with performance metric Object Concurrencies.
     • Namespaces: number of namespaces.
   • Block service:
     • Hosts: number of hosts.
     • VBS Nodes: number of VBS nodes.
     • Volumes: number of volumes.

4. In the Hardware area, view hardware information about the storage system.
   • Disks: displays disk information (excluding system disks), including the numbers of faulty, subhealthy, and healthy disks.
   • Storage Nodes: displays information about storage nodes, including the number of faulty and healthy storage nodes.
   

   Click More to view details about the storage system hardware on the Hardware page.

5. In the Available Capacity or Usable Capacity area, view the capacity information of each service type in the storage system, including the disk type, used capacity, total capacity, and capacity usage.
   

   • After you upload a purchased license, the capacity information is displayed based on the license type.
   • When a license that supports scenario-specific SmartCompression is imported, Usable Capacity is displayed in this area. In other scenarios, Available Capacity is displayed in this area.
     • Usable Capacity: indicates the actual available physical capacity of disks in the storage system (excluding the capacity consumed by EC redundancy or the capacity lost due to hardware faults).
     • Available Capacity: indicates the system-estimated data volume that can be written by users.
   • If the storage system is upgraded from an earlier version with a raw capacity license imported to the current version, Capacity is displayed in this area, including Total capacity, Used raw capacity, and Free raw capacity.
     • Total capacity: total applied license capacity.
     • Used raw capacity: used raw capacity of physical disks in storage pools.
     • Free raw capacity: Total capacity – Used raw capacity.
   • When the ratio of the used capacity to the total capacity exceeds 80%, the progress bar is in orange, indicating that the capacity is about to be used up.
   • Storage system capacity conversion: 1 PB = 1,024 TB, 1 TB = 1,024 GB, 1 GB = 1,024 MB, 1 MB = 1,024 KB, and 1 KB = 1,024 bytes

6. In the Top 5 Storage Pools by Usage area, view the capacity trend of the top 5 storage pools sorted by capacity usage in descending order.
   

   You can click More in the upper right corner of the Top 5 Storage Pools by Usage area to view details about existing storage pools of the storage system on the Storage Pool page.

7. In the Alarms area, view alarm information about the storage system, including the total number of alarms, alarm severities, and number of alarms of each severity.
   

   You can click More in the upper right corner of the Alarms area to view details about current alarms and events of the storage system on the Alarms and Events page.

8. In the Performance area, view the performance indicators of each protocol type in the storage system.
