Total Backend I/O Rate First Top 8 Ldevs Report - HPE XP7 User Manual

In the LDEV I/O Mapping table:
• Hyphen (-) is displayed in the RAID Format column if that RAID format is not applicable for THP Pool
V-Vols.
• Hyphen (-) is displayed in the LUSE Master column if the LDEV record is not a LUSE Master. So, the
LDEV will either be a LUSE component or an individual volume (not part of any LUSE).
• Hyphen (-) is displayed in the LUSE Status column if the LDEV record is neither a LUSE master nor a
LUSE component. The LUSE Status is not applicable for such LDEV records.
A sample of each report is given below:

The maximum throughput varies depending on RAID level and disk mechanism type and other factors
such as the size of the individual I/Os. Figure 20: Total Backend I/O Rate First Top 8 LDEVs on page
