ThP Pool Occupancy report

The THP Pool Occupancy report provides the usage percentage of the eight busiest ThP pools.
Following are the types of charts that are available when you generate ThP Pool Occupancy report for
XP, XP7 or P9500 Disk Arrays:
• Total THP Pool Utilization, First Top 8 THP pools, shows the pool occupancy by the 8 THP pools.
• Total Front-end I/O Rate, First Top 8 Pools, shows the number of I/O operations performed by the first
busiest 8 THP pools.
• Total Front-end MB Rate, First Top 8 Pools, shows the number of MB operations performed by the first
busiest 8 THP pools.
• Total Back-end Track I/O Rate, First Top 8 Pools, showing the real back-end I/O rate sustained by the
first busiest 8 THP pools.
• Max read response time, first top 8 pools, shows the max read response times for the busiest 8 pools
of the XP disk array. The max read response time depends on factors such as, but not limited to, the
RAID level and disk mechanism type configured in the pool, pattern of the I/Os (sequential or random),
size of the individual I/Os and cache configurations.
• Max write response time, first top 8 pools, shows the max write response times for the busiest 8 pools
of the XP disk array. The max write response time depends on factors such as, but not limited to, the
RAID level and disk mechanism type configured in the pool, pattern of the I/Os (sequential or random),
size of the individual I/Os and cache configurations.
• Average read response time, first top 8 pools, shows the average read response times for the busiest
8 pools of the XP disk array. The average read response time depends on factors such as, but not
limited to, the RAID level and disk mechanism type configured in the pool, pattern of the I/Os
(sequential or random), size of the individual I/Os and cache configurations.
• Average write response time, first top 8 pools, shows the average write response times for the busiest
8 pools of the XP disk array. The average write response time depends on factors such as, but not
limited to, the RAID level and disk mechanism type configured in the pool, pattern of the I/Os
(sequential or random), size of the individual I/Os and cache configurations.

Snapshot Pool Occupancy report

The Snapshot Pool Occupancy report provides the usage percentage of the eight busiest snapshot pools.
NOTE: PA reports only those snapshot volumes in an array that are assigned to a pool.

Continuous Access Journal Group utilization report

The Journal Pool Utilization report displays the utilization percentage of the eight busiest Journal groups.
Figure 38: Continuous Access Journal group utilization on page 324 displays a sample Continuous
Access Journal Group Utilization report for a P9500 Disk Array.
