nning guide critical april 18 2025 sap hana sap hana use a separate disk for each sap hana filesystem for optimal performance of your sap hana system google cloud recommends that you use a separate disk for each sap hana filesystem notably the disks hosting the sap hana data and log volumes must not be used for any other function such as serving as the installation path or system instance path this recommendation also applies to the sap hana backup volume if you save your backups to a disk hosting filesystems on separate disks is also recommended to be able to use data snapshots as a backup and recovery option from october 27th 2025 the severity of this evaluation rule has been updated from medium to high this change also applies to existing evaluations that include this rule for more
