Bug Alert - 12732502 !! CALIBRATION_IO RESULT IS 10 TIMES HIGHER (IOPS) THAN ORION

Oracle Support has confirmed that it's a bug.  Oracle Development is currently working on the patch to fix this issue.

Bug 12732502 - CALIBRATION_IO RESULT IS 10 TIMES HIGHER (IOPS) THAN ORION

SQL> set serveroutput on

declare

max_iops integer;

max_mbps integer;

SQL> 2 3 4 actual_latency integer;

5 begin

6 dbms_resource_manager.calibrate_io (

7 num_physical_disks => 20,

max_latency => 10,

8 9 max_iops => max_iops,

10 max_mbps => max_mbps,

11 actual_latency => actual_latency);

dbms_output.put_line ('IOPS = '|| max_iops);

12 13 dbms_output.put_line ('MBPS = '|| max_mbps);

14 dbms_output.put_line ('Latency = '|| actual_latency);

15 end;

16 /

IOPS = 74644

MBPS = 1219

Latency = 1

And here is the ORION test result on the same luns (5 luns, 20 physical disks)

-run advanced -write 40 -testname traxpoc -num_disks 20 -cache_size 8000 -duration 240 -matrix basic

Maximum Large MBPS=430.41 @ Small=0 and Large=39

Maximum Small IOPS=5297 @ Small=95 and Large=0

Minimum Small Latency=5.07 @ Small=3 and Large=0
