THE PERFECT MARRIAGE: ZFS STORAGE APPLIANCE AND EXADATA
As fellow database administrators (DBA) and database machine administrators (DMA), we want to better leverage the space that we have available on the Exadata. Space is a premium on the Exadata, and we want to squeeze every byte we can. How can we do that? The best-suited answer is the ZFS Storage Appliance. We plan to demonstrate how you can couple the ZFS Storage Appliance (ZFSSA) with the Exadata to fully maximize space utilization by tier-ing storage on the Exadata and ZFSSA. We will also discuss data migration strategies to archive data from DATA and RECO disk groups and to the ZFSSA. Along the way, we can take advantage of Exadata Hybrid Columnar Compression (EHCC) to reduce our footprint even more. We plan to provide insight into optimal RMAN backup settings, direct NFS (dNFS) settings, and quick scripts used to drive throughput on the ZFSSA across all the compute nodes. You will also learn about the power of implementing snapshots and clones to provision databases on the fly, and replication to achieve another level of protection. ZFSSA is not just for the Exadata. We will reveal additional use cases for the ZFSSA that will be relevant for your IT infrastructure.
