Measures reported by HPStOReVTLPfTest
In order to optimize bandwidth usage and throughput, minimize congestions, and maximize the replication speed, administrators need to constantly keep a vigil on how well replication is performed on the Virtual Tape Libraries(VTLs). For this, administrators can use the HPStOReVTLPfTest test.
This test reports real-time metrics of the volume of data received by and transmitted from the VTLs for replication per second. This test also throws light on the count of target replication job sessions and the source replication job sessions established on the VTLs.
Outputs of the test : One set of results for the target HPE StoreOnce Backup system being monitored.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| repRxBandwidth |
Indicates the rate at which actual data (deduplicated data and meta data ) was received by the VTLs for replication during the last measurement period. |
MB/sec |
Any attempt made to transmit or receive traffic faster than the allotted bandwidth can result in congestion. Therefore, administrators should ensure that just about enough data is transmitted and received by the VTLs to prevent congestion and optimize throughput. |
| repTxBandwidth |
Indicates the rate at which actual data (deduplicated data and meta data) was transmitted for the replication of the VTLs during the last measurement period. |
MB/sec |
Any attempt made to transmit or receive traffic faster than the allotted bandwidth can result in congestion. Therefore, administrators should ensure that just about enough data is transmitted and received by the VTLs to prevent congestion and optimize throughput. |
| repRxThroughput |
Indicates the rate at which apparent data was received by the VTLs for replication during the last measurement period. |
MB/Sec |
Any attempt made to transmit or receive data faster than the allotted throughput can result in congestion. Therefore, administrators should ensure that just about enough data is transmitted and received by the VTLs to prevent congestion and optimize throughput. |
| repTxThroughput |
Indicates the rate at which apparent data was transmitted for the replication of the VTLs during the last measurement period. |
MB/Sec |
Any attempt made to transmit or receive data faster than the allotted throughput can result in congestion. Therefore, administrators should ensure that just about enough data is transmitted and received by the VTLs to prevent congestion and optimize throughput. |
| repInSessionCount |
Indicates the number of target replication job sessions established on the VTLs during the last measurement period. |
Number |
|
| repOutSessionCount |
Indicates the number of source replication job sessions established on the VTLs during the last measurement period. |
