To open the Clients page, click Storage > Clients. This page displays the total number of clients that are connected to the DR Series system, which can be a combination of NFS, CIFS, RDS, OST, NDMP, iSCSI, and DR2000v clients. The total number of clients is listed above the tabs (NFS, CIFS, RDA, NDMP, iSCSI, and DR2000v tabs).
Depending on the tab you select, the number of clients for each connection type is displayed, as well as other information about the clients. For example, if you select the RDA tab, the number of current OST or RDA clients (OpenStorage Technology or Rapid Data Storage clients) that are connected to the system are displayed. The RDA tab also provides the following types of client-related information:
|
• |
Number of RDA Clients — The number of OST and RDS clients. |
|
• |
Name — Each client referenced by name. |
|
• |
Type — The type of RDA clients. |
|
• |
Plug-In — The plug-in type installed on each client. |
|
• |
Backup Software — The backup software used with each client. |
|
• |
Idle Time — The idle time (non-activity) for each client. |
|
• |
Connection — The number of connections for each client. |
|
• |
Mode — The current mode type for each client. |
On the Clients page (Storage→ Clients), click the NFS or CIFS tab to view the following information for NFS or CIFS clients.
|
• |
Name — lists each client by name. |
|
• |
Idle Time — lists idle time (nonactivity) for each client. |
|
• |
Connection Time — lists connection time for each client. |
To display the Clients page, click Storage→ Clients. This page displays the total number of clients that are connected to the DR Series system, and this number reflects all of the clients based listed under the Clients tab (NFS, CIFS, and RDA). Using this page and the RDA tab lets you perform the following tasks for RDS or OST clients:
|
◦ |
Auto: DR will set the deduplication to Dedupe or Passthrough, based on the client’s number of cores and whether it is 32– or 64–bit. |
|
◦ |
Passthrough: The client will pass all data to DR for deduplication processing (appliance-side deduplication). |
|
◦ |
Dedupe: The client will process hashing on data, so deduplication processing occurs on the server side (client-side deduplication). |
If an OST or RDS client has four or more CPU cores, it is considered to be dedupe-capable. However, the OST or RDS client operating mode depends upon how it is configured in the DR Series system (Dedupe is the default RDA client mode).
|
• |
|
• |
If an OST or RDS client is not dedupe-capable (meaning the OST or RDS client has less than four CPU cores), and the administrator sets it to run in the Dedupe mode, it will only run in the Passthrough mode. |
|
• |
If an OST or RDS client is set to run in Auto mode, the OST or RDS client will run in the mode setting determined by the media server. |
The following table shows the relationship between the configured OST or RDS client mode types and the supported client mode based on client architecture type and corresponding number of CPU cores. For information about Rapid NFS and Rapid CIFS supported client modes based on architecture and CPU cores, see Best Practices: Rapid NFS and Best Practices: Rapid CIFS.
On the Clients page (Storage > Clients), click the NDMP tab. On this tab, you can view the following information for NDMP clients.
|
• |
ID — NDMP session ID. |
|
• |
Duration — The duration of the current active session. |
|
• |
State — The current status, for example, Active. |
|
• |
Source — IP address of the source filer. |
|
• |
Target — The target tape drive being used for the current NDMP session. |
|
• |
Throughput — The current and average throughput. |
|
• |
Transfer size — The total size of data transferred in this backup session. |
|
• |
DMA — The IP address of the DMA initiating the backup. |
|
• |
NDMP Completed Sessions Statistics — Shows the above information for any completed NDMP sessions. |
