6 Hot and Cold Data Oracle 12c ILM, Heat Map à What if cold data becomes hot again? You can define what cold data is à ex. Data elder than 18 month is definitely cold You can measure the reads and writes on an object. If there are lots of reads with less writes, the object is a candidate for hcc on a ZS-Storage appliance. à ask for paragon data tool kit for determing cold data Seite 6

12 Some ideas for HA without two exadatas Running exadata as a consolidation plattform? But only some databases need a HA construct? Physical standby databases? You are running hcc on exadata? What about the standby database without exadata? à ZS Appliance or FS1 for serving the standby database hcc aware Log shipping primary site exadata standby site 2 x x5 Server, infiniband ZS3 Appliance SAS storage, infiniband Seite 12

13 Some facts about costs exadata storage server: 0,40 / 1GB ZS Appliance sata: 0,02 / 1GB sas: 0,10 / 1GB Seite 13

14 Test databases running on exadata db servers stored on zs appliances save licence costs for test databases 10 prod DB 5 test DB connected by infiniband active ressource management ok for functional tests, not ok for performance tests! Seite 14

15 Summary Oracle ZS appliances makes Oracle exadata more profitable Oracle ZS appliances make exadata backups more performant Oracle ZS appliances save expensive hard disk space on the exadata storage servers Oracle ZS appliances serve test databases very efficient not running performance tests, saving licence costs.
