I've been presented with the following scenario: - this is to be used primarily for ORACLE, including usage of ORACLE RMAN backups (to disk) - HP SAN (will NOT do JBOD) - 256 Gb disk available on high-speed Fibre Channel disk, currently on one LUN (1) - 256 Gb disk available on slower-speed SATA disk, currently on one LUN (2) - the mount point must be /ora01 to match legacy scripts
First proposed solution: - create one zpool using FC disk to hold ORACLE apps and data - create one zpool using SATA disk to hold user directories, RMAN backup files, etc. I think this lacks vision. My proposal (which I'm rethinking and request suggestions): - create one zpool out of both LUNs, perhaps a zpool mirror - create /ora01, /ora_RMAN and /users zfs file systems underneath Hence: 1. My understanding of the situation is having a zpool on a single LUN precludes some ZFS technology such as self-healing, hence is not best practice. Right? 2. My understanding of the situation is that ZFS is capable of detecting the fast FC disk vs. the slow SATA disk and arranging the underlying storage to best take advantage of this eg. shuffle the snapshots off to slower disk. Right? 3.
