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 ETERNUS8000 and ETERNUS4000 (except models 80 and 100) 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.

  • ETERNUS8000 and ETERNUS4000 (except models 80 and 100) CA performance information displays FC-CA port 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.

  • 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".

  • The CPU and ROE usage rates are displayed for the CM load (CPU usage) for 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.

  • Performance information for Thin Provisioning Volume and RAID Group used by Thin Provisioning Pool in the ETERNUS8000 and ETERNUS4000 (except models 80 and 100), will not be displayed.
