ACFS fragmentation

Hi all !

No clear answers in the ODA forum so I'll try here:

We suspect our Oracle Database Appliance box's suffering from fragmentation /performance issues ...

(Virtual Platform with ASM/ACFS deployment, running for +3 years,  growing from 3-> 10 TB)

Did some simple disk tests and I'm curious if these figures still are "normal" !?

Test performed in ODA_BASE

Prod box:

Data/tbs disk

hdparm -t /dev/asm/cobra1p-470

Timing buffered disk reads: 352 MB in  3.01 seconds = 116.90 MB/sec

FRA disk

hdparm -t /dev/asm/datastore-140

Timing buffered disk reads: 298 MB in  3.02 seconds =  98.52 MB/sec

***********************************************************************************

Test box 1

Data/tbs disk

hdparm -t /dev/asm/datastore-144

Howdy, Stranger!
