Danas,
you can choose between using Microsoft Windows MP I/O or using NetApp Data ONTAP DSM.
You MUST use Host Utilities in both cases tho! Host utils will install MS Windows MP I/O anyway, it just depends on you then to either use MS internal DSM or the NetApp DSM.
Host Utils are a must because they set HBA & Disk Timeouts to NetApp recommended values.
Kind regards
Thomas
