7.1.1 Performance Information Types

The following information can be managed: Performance monitoring can be set at different intervals, refer to "7.2.3 Setting monitoring intervals" for the settings available for each device.
On the following tables, "A" indicates "Available", "N/A" indicates "Not Available".

Note

  • When RAID Consolidation is performed in ETERNUS6000 the RAIDGroup response time will not be displayed.

  • LogicalVolume(LUN) and RAIDGroup performance information including LogicalVolume, created by LUN Concatenation in the ETERNUS4000 (except models 80 and 100) and ETERNUS8000 that firmware versions are before V11L40, will not be displayed.

  • Performance information about the ETERNUS disk storage system main frame volume and MVV/SDV are not supported, and performance information values for RAIDGroup cannot be guaranteed.

  • On ETERNUS6000 devices, CA performance information relates to the FC-CA or FC-RA port. Furthermore, performance information obtained during the execution of REC and ROPC is displayed as Write performance information, regardless of whether FC-RA port is set up on the Initiator side or the Target side.

  • On ETERNUS4000 models 300 and 500 and ETERNUS8000 models 700, 900, 1100 and 2100, the CA performance information displays FC-CA or FC-RA port performance information. Performance information during the execution of REC and ROPC will be displayed as follows.

    • It will be displayed as Read performance information, if FC-RA port is set on the Initiator.

    • It will be displayed as Write performance information, if FC-RA port is set on the Target.

  • On ETERNUS DX400 series, ETERNUS DX8000 series, ETERNUS4000 models 400 and 600, and ETERNUS8000 models 800, 1200 and 2200, the CA performance information displays FC-CA, FC-RA, iSCSI-CA or iSCSI-RA port performance information. Performance information during the execution of REC and ROPC will be displayed as follows.

    • It will be displayed as Read performance information, if FC-RA or iSCSI-RA port is set on the Initiator.

    • It will be displayed as Write performance information, if FC-RA or iSCSI-RA port is set on the Target.

  • The ETERNUS DX60/DX80 CA performance information displays the FC-CA or iSCSI-CA port performance information.

  • ETERNUS DX90 CA performance information displays FC-CA port or FC-RA port performance information. Performance information during the execution of REC will be displayed as follows.

    • It will be displayed as Read performance information, if FC-RA port is set on the Initiator.

    • It will be displayed as Write performance information, if FC-RA port is set on the Target.

  • The performance information for the number of active disks, power consumption and temperature can be managed by setting to perf.conf file. For the settings, refer to "C.4 perf.conf Parameter".

  • Performance information for VE ports used by 10GbE(XGE) ports is not supported, and the values in the displayed performance information are not guaranteed. It is recommended that 0 be set for the transfer rate for VE ports used by 10GbE(XGE) ports, and that performance and threshold values should not be monitored. For details on how to set this value, refer to "C.14 Explanation of the Configuration Settings File".

  • The CPU and ROE usage rates are displayed for the CM load (CPU usage) for ETERNUS DX400 series, ETERNUS DX8000 series, ETERNUS4000 models 400 and 600 and ETERNUS8000 models 800, 1200 and 2200. For other ETERNUS disk storage systems, the ROE usage rate is not displayed. Also, for ETERNUS disk storage systems that do not have a ROE, the parity generation processing for RAID5 and RAID6 and encryption processing that would otherwise be performed by the ROE are performed by the CM and the CM-CPU.

  • RDB performance information cannot be displayed in environments that use the REC Disk Buffered Consistency function.
