Description

Diskperf is a tool testing the performances of the disks subsystem.

Some possibilities:

  • read only/read-write/write only.
  • sequential or random I/O
  • different size for read I/O and write I/O
  • bypass Virtual IO Cache
  • send simultaneous I/O on severals disks
  • generate a report and a CSV result file, so results can be graph using your favorite tool
  • etc...

Example

$ define diskperf sys$disk:'f$directory()'diskperf
$ set comm  sys$disk:'f$directory()'diskperf.cld
$ diskperf $1$dka100 -
        /type=read/range=(start:1,size=1000000)/rand -
        /nocach/end=sec:15 -
        /io_size=(min=6,max=12)/simultaneous=8 /pass=3
