Niall,
When I use AWR report with Tyler Muth 's tool, I see about 5.3 as Total IOPS
when I use the script below from Alejandro Vargas's blog, it says there
are 55.1697642 as PHYS_IOPS_TOT.
Which one is correct? Any idea please?

*spool io_maxtot_summary.log*
*select min(begin_time), max(end_time),
sum(case metric_name when 'Physical Read Total Bytes Per Sec' then maxval
end)/1024/1024 +
sum(case metric_name when 'Physical Write Total Bytes Per Sec' then maxval
end)/1024/1024 +
sum(case metric_name when 'Redo Generated Per Sec' then maxval
end)/1024/1024 Phys_IO_Tot_MBps,
sum(case metric_name when 'Physical Read Total IO Requests Per Sec' then
maxval end) +
sum(case metric_name when 'Physical Write Total IO Requests Per Sec' then
maxval end) +
sum(case metric_name when 'Redo Writes Per Sec' then maxval end)
Phys_IOPS_Tot,
sum(case metric_name when 'Current OS Load' then maxval end) OS_LOad,
sum(case metric_name when 'CPU Usage Per Sec' then maxval end)
DB_CPU_Usage_per_sec,

Host_CPU_util, --NOTE 100% = 1 loaded RAC node
